Sunpower Solar Panels Review | #1 Residential Solar Panel?

Sunpower Solar Panels Review
When it comes to residential solar panels, Sunpower solar panels have been on top of the consumer choice list. Sunpower solar panels have been called the most efficient and worthy rooftop solar panels, but what makes them special? Many aspects of SunPower solar make them stand out from the crowd but in this SunPower solar panels review, let us dig deep into their technology and solar modules.

SunPower Solar Panels- How it All Started

Early in the ‘80s, SunPower embarked on an unofficial mission. It all started in a lab where they experimented with various solar panel technologies before launching as SunPower- the brand, in 1988. The R&D team’s initial financial acquisition allowed for the formal excursion to take place.
After then, there was no looking back since they collaborated with Honda, the legend of a brand, to build record-breaking PV (photovoltaic) cells utilizing cutting-edge cell technology and went on to win the world solar challenge automobile race, which established them as renowned pioneers of the renewable energy sector.
Over a 25-year period, their presence can be seen in a multitude of NASA programs as well as other aircraft projects. San Jose, California, is where SunPower’s corporate offices are located.
They also have the designation of Bloomberg Tier 1 ranking, which is a sign of the company’s financial soundness rather not necessarily of the high calibre of its panel. If this label is current, it implies that the company is a well-known major manufacturer that has successfully served clients on a worldwide scale for a long time.

About SunPower Solar Cell Technology

On the basis of pure tech advancements, there is no denying SunPower research and development team has been doing the most with the utmost quality assurance. 22.8% panel efficiency is the best in the market and undefeated so far, and that, paired with 420W panels, seems like a match made in heaven. Not only that, their cell technology of Maxeon cells, IBC cells and shingled cells are spectacular.

Let’s get to know them in brief-

Maxeon Cell Technology

Everything is held together by a strong foundation of tin-plated copper on the back of the solar cells. To make their solar panels even more effective, they employ the purest silicon that is created exclusively for solar panels. The Maxeon cells absorb sunlight with their distinctive light-trapping surface, which is also anti-reflective.

The metal gridline that was attached to the front of the solar panels was removed. Because of this, Maxeon cells have fewer shading issues and have a very posh appearance when installed on a rooftop. As said before, they are powered by a solid copper backing, and each cell is joined to the next by thick connectors called strain relievers. These are not always affected by heat; as you know, metal expands in extreme heat.

Maxeon solar cell technology has nearly eradicated the shattering and rusting problem, which historically prevents many solar cells from operating to their full potential. They have a special design that eliminates 85% of the problems that cause conventional cells to fail. SunPower may cost a bit more upfront, but you will enjoy the rewards in the long term.

IBC Solar Cells

IBC, or interdigitated back contact, is a form of solar cell that, in contrast to conventional solar cells, converts energy from the cell’s forward contact to the rear contact. In contrast to conventional solar cells, this technique enables the whole front portion of the solar cell to function as a vessel for absorbing sunlight without wasting even a single inch of space.

One of the main reasons for efficiency loss is shading issues, which are caused by exposure to heat with metal gridlines. SunPower unveiled their market-leading IBC cell technology to completely eliminate this.

Shingled Cells

Just like rooftop shingles, these cell types work in a similar manner. They are laid in shingles that eliminate the need for busbars that accumulate space unnecessarily. More area of the roof is covered with the use of shingled cells that allows more PV cell space to actually work on generating renewable energy. Electrically Conductive Adhesive, or (ECA) is used to stick all the solar cells together while keeping them working.

To get the best price, you should get multiple quotes from Canadian Solar. Checking out different products might help too. The final price depends on the equipment you get, based on your product. More specifically, the kind of inverter or battery you need with your panel depends on what panel you get. Most Canadian Solar PV systems are priced between $2.70 and $3.20 per watt, making them an excellent value in the home solar market.
This means that the gross cost of a 6 kW system (before any tax credits or other incentives) would range between $16,200 and $19,200.
Furthermore, most homeowners pay far less than the total gross cost. With the federal solar tax credit of 26 percent, a 6 kW system with Canadian Solar panels would cost between $11,988 and $14,208. And everyone is eligible for the said credit. Numerous state-level solar incentives and rebates are available to help you further reduce your upfront costs. 
The table provides below is not an exact amount. Rather, it’s an approximate amount. Check out the best solar packages here. 
System Size (kW).Average cost (with installation)
6kW$11,988 – $14,208
8kW$13,500- $15,650
10kW$16,550- $17,900


“Solar panel efficiency” refers to how effectively a solar panel captures and converts sunlight into usable electricity. A high-efficient solar panel can produce more electricity than a lower-efficient panel of the same size under the same conditions. As a result, a higher efficiency rating is generally preferred.
The efficiency of your Canadian Solar panels will differ depending on the model you select for your system. The efficiency rating of Canadian Solar panels ranges from 15.88% to 20.60%.

Performance (temperature coefficient) 

The temperature coefficient indicates how well your solar panel will perform in less-than-ideal conditions. Like other electronic equipment, solar panels perform better when kept cool (ideally at temperatures around 25° C/77° F). The temperature coefficient indicates how much your panel performance will change during hot, sunny summer days.
Your solar panel’s electricity production decreases by a temperature coefficient for every degree above 25° C (77° F). The temperature coefficient of the Canadian Solar CS1H-325MS panel from their HIDM residential series, for example, is -0.37%/°C. This means that if the temperature of the panel rises by one degree, from 25° C (77° F) to 26° C (79° F), electricity production will fall by 0.37%. If the temperature rises to 35° C (95° F), electricity production will fall by 3.7%.
Your solar panels will most likely see a few hot and sunny days throughout the year, so they should have the lowest temperature coefficient possible.
The temperature coefficient of Canadian solar panels ranges between -0.41 and -0.35.


Whether you’re purchasing a television, a car, or solar panels, the manufacturer should provide a strong warranty. The materials warranty (also known as the product or equipment warranty) of a solar panel is a guarantee from the manufacturer that they will replace your panel if it fails due to manufacturing defects or environmental issues.
Depending on the product line, Canadian Solar provides a warranty of up to 15 years for defects in their solar panels. Warranty claims were also made easier by the government of Australia. 

Pros and Cons of Canadian Solar 

Canadian Solar panels provide various options for solar systems. There are solar panels that range from average to extremely well-performing. However, it depends entirely on the user and what they are looking for in a solar panel; this determines whether it is worthwhile.

How Do Portable Solar Panels Work

how do portable solar panels work
The concept of residential solar panels is known by most of us. However, portable solar panels have gotten quite a lot of attention for their portability, of course, and also for their ease of installation, more like no installation. For those who like camping or love to be on the roads for intercity vacations, portable solar panels are a must-have. Sometimes when you choose to live off the grid, having access to portable solar panels will surely come in handy in any unforeseen circumstances.
How do portable solar panels work, then? What do you need to keep in mind before you buy portable solar panels? All are discussed below-

Portable Solar Panels- Their Mechanism

There are several different sizes of portable solar panels, depending on which they work differently. The one which is tiny and foldable typically ranges between 10W to 40W panels. These foldable solar panels, if exposed to sunlight, can generate ample solar energy to charge any devices like a phone, portable speaker, power bank, etc.
solar panel for camping
Also, there are some portable solar panels that offer a bit more power than carry-ons. These solar panels range between 70W to 100W. They are perfect for your day trip or weekend getaways when your electronics require a little more juice to rev up. These portable/ personal solar panels are ideal for your needs, whether you’re an extreme hiker venturing into the wilderness or a sunbather trying to complete some work in your neighborhood park.
A factor to keep in mind here is the higher the wattage the portability of the panels drops. If you need a solar panel that can provide more than 100W to 120W of backup, it can lose the easy access and mobility aspect of it.
Most portable solar panels work the same way as the regular ones do. But there is no bulky solar inverter in most cases. These portable solar panels come with integrated charge controllers to regular the DC to AC flow. Those who don’t come with a charge controller will auto-charge the solar battery that comes in the package, and you can use that as the primary source of power.
A USB port and a DC output connection are likely to be present, enabling customers to immediately charge their smartphones or laptops. Portable lithium-ion batteries are most frequently used in conjunction with portable solar panels to ensure that their energy may be utilized in any circumstance. (While it is in use, the battery cannot be charged.) The batteries can have a wider variety of output devices, including DC output jacks and common domestic 120-volt AC outlets.

What to Look for When Buying Portable Solar Panels

When you are buying portable solar panels, make sure you check on the followings –

Quality of The Panels

The quality of the panels makes a world of difference. Make sure you go with monocrystalline panels over polycrystalline because they provide higher efficiency, which is crucial. There are many other attributes of portable solar panels which make them of better quality. For example, if they come with an integrated charge controller, they would be able to regulate power better without harming the storage unit. So, keep an eye out for it.

Price Range

Portable solar panels come in different varieties and sizes. Which can alter the price range. Depending on what your agenda is with the portable PV set, you have to set a budget. If you only plan to occasionally use it for camping or hiking, then low-budget ones can be your choice. Otherwise, a bit on the high-range panels is the best choice if you plan to use it a bit more frequently.

Weatherproof or Not

If the panels are weatherproof or not is a huge factor that can make or break the deal. Essentially portable solar panels are purchased with the intention of being carefree with them in terms of usage and carrying. Also, they need to withstand harsh weather and roads to be carried into the middle of nowhere to serve their purpose. For that reason, make sure the panels you choose are sturdy and weatherproof.
Portable solar panels are essentially free energy on the go. We highly encourage everyone to opt for renewable energy sources at any chance they get so that our carbon footprint can remain at a limit. With these small changes in adopting clean energy, we can make a huge difference in the long run.

Tier 1 Solar Panels Brands

I’m pretty sure you’ve come across a title that reads, “Our panels are listed Tier 1” while searching the internet for the optimal solar panel. Anyone would presume this to be a quality indicator at first look, but that is not the case.
A production line for that specific panel with a tier 1 rank is an entity that signifies it is in good financial standing. That’s great for the business, but why should it matter to you? According to the manufacturer and panel model, a solar system comes with a guarantee that lasts between 25 years and 30 years. Would the 30 year panel warranty still prevail if the firm closed within that time frame because it was not financially stable? Nope, I quite don’t think so.
There are anecdotes I can recall in which this did happen, and some companies kept the promise of availing solar panel warranty, and some failed miserably. So, it’s better not to take such a risk.

Solar Panel Warranty

The majority of solar panels have a product warranty that lasts from 25 years to 30 years. Due to the fact that solar panels are not inexpensive, a warranty is a crucial consideration and must have; the higher the number of years, the better. Although there are less expensive options, they are still regarded as being inferior to certain other solar PV.
There are several types of warranties, such as product warranty, performance warranty, parts warranty, etc., make sure you understand and get a good warranty offer.
Additionally, some solar panels have a third-party warranty program. So be sure to thoroughly consider it before you make a purchase. Or you can designate us to handle the task and simplify your life.

Solar Panel Degradation Curve

Imagine you still own the same cell phone you bought five years ago. Yes, you may be using it, but does it still function the same way that it did five years ago? I sincerely doubt that it does. Similar to this example, the efficiency rate of a solar panel closely correlates with how well it performs as it matures. This occurrence is known as degradation. The lower this number is, the better.
Keep in mind that nothing good lasts forever; therefore, every solar panel will eventually deteriorate as time goes on. However, what actually matters—and what you should take into consideration as a key factor—is the rate at which the panel deteriorates.
In simpler words, the degradation of solar panels is bound to happen but at what rate is it happening is what matters. The degradation should happen slowly over the course of several years. Check the performance history of the choices you picked so far, or simply consult a solar expert.

Solar Panel Temperature Coefficient

The temperature coefficient is the percentage by which your panels’ effectiveness falls off when the temperature goes over their ideal level, which is 25 degrees Celsius. A solar panel that is very efficient will have a low temperature coefficient, whereas one that is less efficient will have a greater temperature coefficient.

Australian Presence

Make sure the company you choose has a presence in Australia before you commit. The worst-case scenario can occur suddenly, and the business you select to purchase from may go bankrupt. This is merely a plausible outcome.
how to buy solar panel
What happens if the firm from which you purchased your solar panels, ‘X,’ goes out of business and you need to lodge a warranty claim? Would you hold the installer accountable? They weren’t the true supplier; therefore, it doesn’t work like that. But they can definitely help you with it but remember, certain limitations do exist in extreme events like this.
Additionally, it is vital to know that the panels you are spending so much money on have a real office in your country. This way, you may ask them for assistance or use their services whenever you need them.
Now that you know how to buy the best solar panel, please understand that buying the solar panels is only half the job done. I can’t emphasize enough how crucial it is to supervise and ensure that the installation is done exactly according to the rules because the installation procedure determines the other 50% of the remaining job.
Go with a CEC-approved installer who knows what they are doing and what’s best for your property and your future.

What Happens to Solar Panels After 25 Years

what happens to solar panels after 25 years

Among all the renewable energy sources, solar panels are the the most accessible one for families all across the globe who are looking to switch to a greener source of energy while decreasing their electric bill.

Solar panels are also becoming less expensive as we speak, making them a perfect candidate for a sustainable energy source for most of us. With easier access, wide availability and government rebates, smart families are switching to solar; however, they last about a maximum of 25 years to 30 years. So, what happens to solar panels after 25 years?

Almost 95% of solar panel are recyclable. That means when solar panels reach an end of life, they can be recycled! Dumping ‘dead’ solar panels in landfill have been completely banned by the Victorian government because any sort of electronic waste is banned.

However, there are far fewer recycling facilities across the country present, making it difficult to recycle at the moment. The good news is multiple initiatives are on the way for establishing recycling facilities in Australia.

At the moment, Lotus energy is the most active in this field, and they already got started with recycling in the past panel lifespan

Why Recycle?

Australia is expected to produce one million tonnes of waste (solar panels) by 2047; according to Macquarie University, this amount is likely to rise as more families upgrade their systems rapidly. To help photovoltaic (PV) cells convert sunlight into energy, solar panels are mandated to include hazardous substances (if disposed of incorrectly) like lead. These chemicals may seep out when old and damaged panels are dumped, creating dangerous conditions.

That makes it crystal clear, if not dealt with correctly, it can be a task to dispose of outdated panels. So, it makes total sense for panels to be recycled and not just left to be a massive pile of e-waste when the first wave of solar panel dumping starts.

What Other Options are Available Other Than Recycling

Instead of recycling, there are many ways a solar panel can be disposed of. There are many services available that take care of your electronic waste, such as solar panels, and take measurements for proper disposal. Because dumping them in landfills is illegal, many local councils can be tipped off.

Other than that, you can also reuse the panels and make it a part of your camping essentials. Even after solar panels reach its official end of time, they can still produce some electricity if used in bright sunlight and cleaned properly.

Also, there are many offshore facilities for recycling solar panels. You can contact the relevant government departments or the IRENA (International Renewable Energy Agency), or your initial installer to talk about your solar replacement options.

How To Make My Solar Panels Last Longer?

To get the most out of your solar panels, you must taking precautionary measures from day 1. You know what they say, precaution is better than cure! In these measures, you can take the installation process itself as the first task. Make sure you go with a team of professionals who knows what they are doing. Please note, they must be approved by the CEC (Clean Energy Council).

The entire rooftop solar system has to be of high quality for it to be long-lasting. Also, check the government rebates, the components used have to be CEC-approved.

Make sure you clean your solar panels at least twice a year, so that excess amount of dirt and debris don’t accumulate on them, creating a barrier for proper sunlight to shine. This is deemed as a shading issue, which lowers the efficiency of solar panels by almost 50%.

So, what happens to solar panels after 25 years is they go through a proper recycling and disposal channel and get a second life. Unfortunately, the unavailability of such facilities results in the panels being dumped unethically. To prevent such occurrences, the Australian government is soon to take measurements in the upcoming years.

Are Solar Panels Recyclable | The 2022 Update

Are Solar Panels Recyclable

In the past decade, people have gravitated towards renewable energy sources the most than at any other time. Among all of the sources, solar panels on a residential scale were welcomed the most. However, when the world seemed to have geared up for renewable energy sources like solar panels, the long-term management of such a change was given little to no thought.

Solar panels have a lifespan of about 25 years to 30 years at max. What happens to all these solar panels after they reach the end of the line? Are solar panels recyclable? To answer it simply, yes, they are recyclable for the most part. On average, 90%- 95% of the photovoltaic cells which are made of silicon are recyclable. But the question remains are they getting recycled even if how easy it is to do so? That is something to work on as soon as we can.

How are Solar PV Panels Recycled?

Let’s take a look at the basic solar model made of silicon. There are essentially two types of solar panels; monocrystalline solar panels and polycrystalline solar panels. Both of the types have an equal ability to get recycled as it’s the way the silicon is laid out that decides the type of solar panels. Other than these two, a separate kind of solar panel is present, which is a thin film solar panel. Thin film solar panels are not made of silicon; rather, they use one of the following-
  • Cadmium Telluride (CdTe)
  • Amorphous Silicon (a-Si)
  • Copper Indium Selenide (CIGS)
This type of solar panel is rarely used for residential purposes as they don’t offer efficiency while the cost soars up pretty high. Usually, thin film solar is used in a commercial setting because of their other advantages, like they use fewer materials to get produced, they deal with shading issues, and low light conditions pretty well. However, still, the prices are not conducive to the outcomes.
can solar panels be recycled in australia
For those reasons, we will be limiting today’s discussion to silicon-made solar panels only.
In essence of it, a solar panel is a glass-trapped silicon module that is framed in aluminium. The wires are made of silver and copper. All of which are recyclable using different methods.
The first step to recycling is disassembling the solar panels. The frames, glass, silicone body, and wires get disassembled. Separately they get recycled in large quantities. The entire process does take a lot of big machinery, and the process itself gets a bit expensive, but the price that we will pay without recycling is greater in the long run.
95% of the glass body gets reused after disassembly, and 100% of the metal gets reused. In this case, the thermal processing takes about heat sources that are 500 degrees Celsius to melt down. The silicon is also heated to break it down to its cellular level to make it reusable.
Don’t think that all of this process takes any manual labor, especially the disassembly; rather, there are many detectors and high-level machinery used in such cases.

Are Solar Panels Recyclable in Australia?

On today’s date, there aren’t many full-fledged facilities for solar panel recycling in Australia. However, last year a solar recycling facility did start operating in Melbourne’s north which has been confirmed by their video footage posted on a social media platform. They work in conjunction with Lotus energy, the first company to take such steps in Australia.
The point to be noted here is not 100% of the panel is recyclable in Australia at the moment; still, it has to be sourced from different off-shore facilities. Only about 17% of the recycling is done in Australia, which includes recycling of the metal frame and the junction box. The rest of the body is yet to be managed, but it is also a fact that in Victoria, this type of waste is considered electronic waste and is completely banned from landfill.
how solar panel recycled
In the future, it has been projected that a national working group will conduct a COAG Regulatory Impact Statement (RIS) to evaluate industry-led and co-regulatory solutions for solar panels, as well as the ensuing regulatory and economic implications. A national working committee will advise the federal, state, and territorial governments on the best management strategy.
Check out this end of life management steps to be taken by the International Renewable Energy Agency (IRENA) here.
So, are solar panels recyclable is not the question that is puzzling but when and how efficiently it can be achieved in our country is the current concern. The government is working on several projects and rebate schemes to make solar energy accessible to the mass. The next big thing to figure out is recycling, for which the authority is already constructing prospective plans for the near future.

Should I Get Solar Battery for My Solar Panel?

should i get solar batteries for my solar panel
One out of four households in Australia has rooftop solar panels in today’s date. Can you guess why people accepted this change with open arms? To get away from the rising electric bills, of course. Also, with the prevalence of solar rebates at the federal and state level altogether, it made perfect sense for you and I to go solar. Because who wouldn’t like the opportunity to save money while saving nature at the same time, right?
Apart from all those good things, do you know what can make this investment even more fruitful? Adding a solar battery storage system to the whole deal. “But aren’t solar batteries expensive?” this is exactly what you might be thinking to yourself. Well, that is not incorrect, but aren’t cars expensive? What about a house? But we still invest in those assets, don’t we? Just like that, getting a solar battery is also an investment that goes a long way if you make the right calls at the right time.
It sounds a bit confusing with just that much information so let me help you out by answering your question, ‘should I get solar battery for my solar panel’ a bit elaborately.

Your Household Electricity Needs

The first step to figuring out if you should go for a solar battery is to know how much electricity you use on a regular day. Calculating that is simple; all you have to do is take a look at your electric bill copy. There you can find a breakdown of your average use in Kilowatts.
solar battery
For an average household of two people, the total consumption of electricity quarterly can be around 950kWh to 1000kWh, with 10kWh to 15kWh daily peak usage. This comes down significantly with the addition of solar panels on the roof and totally disappears with the addition of solar batteries. Since the batteries store electricity for you to use at your convenience, you will be using what you generate through the panels, scratching the grid altogether, and paying zero electric bills.
There is so much more to figure out in this scenario, but with the right assessment and experts working on your property, it’s totally plausible.

How Much Electricity Do My Panels Generate?

Assuming you already have rooftop solar panels, how much electricity they generate is a huge factor to consider. With a smaller solar system that barely fulfills your needs during the day, adding a battery will not be the brightest idea. A battery should be added to such PV systems that are capable of yielding a significant amount of energy.
However, there is an exception to the scenario.
If your area is prone to blackouts, or you get charged a stupidly high rate for energy bills, getting solar batteries in such cases is the optimum thing to do.
Also, if there is room for expansion of your solar array in case you have a smaller system, it’s a smart move if you do so. Because in the end, solar panels are the best way to generate electricity rather than depending on the grid.

When Do I Need Electricity the Most?

Let’s say you do have a smaller solar panel system. As we know, solar panels are able to generate the most electricity during peak hours, which are around 10 am to 3 pm. If you are not around the house at that time, which most people usually aren’t because of work or school, the entire amount of energy generated by even that small system of yours will be exported to the grid. Earning you Feed-it-tariff credits in the process, if applicable, but the credit you get in return is quite insignificant judging today’s market.
What can you do in this case? Get solar batteries so you can store the electricity produced by your panels in the peak solar hours. This way, you will have electricity stored in the batteries to use when the price of grid energy is high. Essentially using free energy when grid users are paying high prices.
solar battery cost

Price of Solar Battery

Recent decreases in solar battery prices are the result of major technological advancements and the availability of resources. Naturally, that doesn’t imply they are suddenly inexpensive, but the decrease is astonishing. A kWh of solar battery storage used to cost anywhere between $3000 and $3600 only for the battery, without including installation. For each kWh of solar battery storage, you can now anticipate paying between $1200 and $1400. It will only get better from here on out—and that’s a price reduction of about 52%.

How Long Do Solar Batteries Last?

A quality solar battery system should back you up for the upcoming 15 years to come after purchasing. But there are also batteries available in the market which last 8 to 10 years, but they cost lesser in comparison. To tell you the truth, if you are planning to invest in solar batteries, there is no need to settle for less; as I already told you, it’s an investment. An investment that can provide you with free energy for as long as it last, obviously, if you pair it up with a quality solar system.
Additionally, by switching to green energy, you not only save a ton of money but also drastically lower your carbon footprint and inspire others to do the same. It’s a crucial measure to protect the next generation from the dramatic and catastrophic effects of global warming.

What Happens to Unused Solar Power

What Happens to Unused Solar Power
As long as the sun shines on your solar panel system, it will generate electricity, it can be less or more at times, but it’s guaranteed to generate power. Solar panels are versatile pieces of tech that don’t require external assistance to work. That is the reason why there can be times when your panels could generate more electricity than you need to run your everyday chores.
So, what happens to unused solar power? Does it go to waste? Not quite. This power surplus can be directed to many outlets to be stored or exported in a public shared utility grid. Let us explore more on the topic.

Grid Connected Solar System

If you have a solar system that is connected to the grid, you can expect the excessive energy to be transported back to the grid. Solar panels are made in a way that it’s not possible to physically turn them off. So, when the sunlight hits the solar panels, the silicon cells initiate the photovoltaic conversion from sunlight to DC (Direct Current), which eventually gets converted into AC (Alternating Current).
If your solar system yields more energy than your house needs in the case of a grid-connected system, then your solar inverters will dictate the situation smoothly. Your solar inverters determine whether the extra energy should be transported back to the grid or to the battery bank, if any.
off grid solar system
What’s in it for you if the energy gets back to the utility grid? Seemingly it’s electricity generated by your paid system. There is an arrangement in place for situations like these, called Feed-in-tariff (FiT) which compensates solar owners for their contribution to the stream with energy credits.
It is a reimbursement for any extra power that is sent back to the grid. It’s often referred to as a buy-back rate and is typically paid as a credit on your bills at a defined amount per kilowatt hour. The terms and circumstances for your solar rates and your energy rates are different, and it depends on many external factors. Learn more about Fit here.

Off Grid Solar System

It’s quite a straightforward deal when your solar panels are installed off the grid. The surplus of energy, in this case, is stored in a battery bank which is typical for an off the grid solar system. One of the main components of an off the grid system is a battery bank because it’s essential to have excess energy to use at night.
But what happens when the batteries are full?
Previously when lead acid batteries were more common for solar energy storage, it was deemed dangerous to overcharge them. As these sorts of batteries release hydrogen gas, overcharging them poses a higher threat of explosion. However, overcharging modern lithium batteries does not harm them to a great extent. Due to the fact that they don’t normally release hydrogen gas, modern lithium batteries provide a far smaller risk. To guarantee the security of the system, they also contain an integrated computerized battery management system.
Learn more about off grid solar systems here.
off grid solar system

Solar Safety – Know When to Stop Exporting

As discussed above, in an instance where the solar system is tied to the grid, the solar inverter can smoothly determine to export the surplus to the grid. This way, you can benefit from FiT and also help reduce the carbon footprint of the mass. This entire process is automated because of the ease of operation and cut back on redundancy.
However, there are times when people work on grid maintenance; also, solar panels continue to produce potentially fatal DC voltage in the case of a short circuit, fire, or water. These are potentially dangerous situations of which we need to be aware of.
Lastly, a well-designed solar system will produce energy in accordance with your needs. However, it’s always preferable to have more than to lack energy when needed. Either you export the surplus back to the utility grid or store it in a solar battery; it’s a win-win case in both circumstances. But refrain from overcharging the batteries to extend their lifetime.

How Do Solar Panels Help the Environment | 5 Solar Benefits

How do Solar Panels help the Environment

We have approximately 11 years to take action to mitigate the negative effects of climate change before the earth faces the consequences of carbon emission (Source).

What can you do to help? Make sound and responsible choices, of course, one of which is choosing a renewable source of energy, e.g., solar panels, to power your house or office, in short, every premise. There are so many insignificant changes and minor compromises you can make around your life to help the earth, however, for now, I will explain how do solar panels help the environment as a renewable source of energy.

Solar Panel- A Carbon Free Path to Energy

It is such a source of energy that emits zero carbon-di-oxide while generating energy for your home. As mentioned before, solar panels are a renewable source of energy harnessing the power of the mighty sun. As long as this solar system exists, so will the sun as a massive energy powerhouse.
How solar panels work is that they are essentially plates of doped silicon that react when the sunlight hits the panel. Different angles and intensities of sunlight projection result in different levels of energy being produced, but the solar panels will generate energy as long as it gets sunlight, more or less. Then a solar inverter converts it into a usable form of energy, and you get to use it to power your home. This entire process happens without any greenhouse gas emissions; thus, your carbon footprint reduces.
Why is the greenhouse gas AKA co2 at a higher level deemed as dangerous? Because co2 absorbs and radiates heat. Don’t get the wrong idea; co2 is an essential gas for the earth because of its heat absorbing and radiating characteristics, which is what keeps us from freezing; however, the higher the amount of it, the higher the overall temperature rises of the earth thus we experience global warming.
The NOAA (National Oceanic and Atmospheric Administration) Global Monitoring Lab found that in 2021, carbon dioxide accounted for nearly two-thirds of the total heating impact of all greenhouse gases created by humans. So, adopting to solar panels, a renewable source of energy, is one of the ways it helps the environment.
Solar panel a carbon free path to energy

Save Water by Choosing Solar

As one of the horrific effects of global warming soon, we will experience a shortage of fresh water supply. Not only do the non-renewable sources contribute to the issue by emitting GHG (Green House Gas) but also, in order to keep them up and running, it takes a huge amount of water to cool down the system down, transport fuel, and refine it. This is a high price to pay for power indeed.
However, by choosing solar panels, you can help save water. Running the panels won’t require any water at all. You might need to do a yearly cleansing for your panels to boost up the power production but to keep the system going, you don’t need a constant supply of fresh water.

Cut Back on Fossil Fuels

Naturally, if you choose to go solar, you will seldom need to rely on the grid. The electricity we use regularly comes from burning fossil fuels, mostly coal, and what happens when you do that? You guessed it! It emits co2, and an increased level of co2 undoubtedly heats up our planet resulting in global warming.
That is not the only problem we face when we burn these natural resources to generate electricity. Sun is the only star of our planet, and it’s not going anywhere for millions of years to come; that is why it’s a ‘renewable’ source; however, fossil fuel is not. We have only so much to go through. It is also a matter of concern that we will not have enough fossil fuel to run essential projects in the future.

Solar Panels are Recyclable

Almost 3 million homes in Australia decided to go solar but solar panels have a lifespan of 25 to a maximum of 30 years. Wondering how will they be deposed off? Well, solar panels are one hundred percent recyclable. In fact, we have a solar panel recycling plant in Australia which started its journey in 2021.
But as each panel is assembled meticulously with different parts and materials at the time of manufacturing and is made to last a long time, it also is a problem when it comes to disassembling it properly. The process of taking apart different parts for recycling is tough, which makes recycling the panels expensive.

Reduces Air Pollution Risk

Coal handling and burning are known risk factors for hazards such as inhalation of carbon monoxide and heavy metals in coal ash. Both forms of exposure put utility and power plant workers at risk of developing interminable lung disease. If our dependency on electricity lessens over non-renewables and shifts to solar panel power generation, we can significantly tone down air pollution.
Not only the workers, the general quality of air decreases for coal burning to generate electricity. Solar panels pave the way for you and me to enjoy the power of the sun without risking our environment, and that too for free!
