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.

Points of Difference and Areas to Improve for SunPower

Here are the advantages and disadvantages of SunPower solar panels.

Pros

  • Their creativity and use of the Maxeon IBC cells to boost panel effectiveness and efficiency are unprecedented. 
  • Peace of mind for decades to come with their 40 year warranty with flagship Maxeon panels and industry-standard warranty of 25 years with value-line solar panels.  
  • No other brand has achieved the highest level of efficiency in the residential solar panel category, which is 22.8% while using the purest silicon in their Maxeon series. 
  • With their latest AC modules, enjoy the perks of microinverters which allows each panel to work individually rather than in a series, reducing their chance of facing shading issues ten folds. This technology has been brought to you in collaboration with the pioneers, Enphase microinverters.  
  • Maxeon series, which also won the first-ever Sustainability Award from PV magazine because of their excellence in participating for the growth of clean energy. 
  • 0.005% chance of you returning your SunPower solar panel, statistically speaking.  
  • Various certifications, such as Cradle to Cradle and ISO, were obtained for their outstanding performance and efficient solar panels. 
  • Aesthetically enticing appearances to provide the homeowners’ roofs with a stylish outlook.  
  • As the solar panels can range up to 440W per panel, with less roof space, you can have twice as much power output in comparison to regular solar panels available in the market.  
  • Bloomberg Tier-1 solar system ranking for the company is present.  

Cons

  • SunPower solar panels come at a higher price point which can be considered a disadvantage; then again sustainable energy source of such calibre is an investment. Investments with insane ROI come at a price.  

SunPower Solar Panel Warranty

With a whopping 40 years of product and performance warranty with all the solar panels except the more affordable performance panels is astounding. As their panel return rate is already only 0.005%, where they sold over 30 million units, the company has confidence in its products which shows with such a long warranty period backup. Also, their degradation rate is 0.25% only which is impressive.  

Certifications and Achievements

SunPower solar panels are proud holders of many achievements and certifications so far, which further strengthens their claim to be one of the best in the category.  

The company has the Bloomberg Tier-1 ranking, which is proof of their financial solvency. This is an important marker when it comes to backing up such a huge warranty claim of 40 years. A bankrupt or soon-to-be broke company cannot provide you with the confidence to keep this promise.  

Also, they are PV evolution labs, one of the top performers. This proves their products are of top-notch quality. It indicates that in various weather conditions and in different situations, SunPower solar panels will still perform as expected. Point to be noted- this is a voluntary test in which SunPower participated at their own accord.  

SunPower solar panels also have an Australian office which is great for any emergency queries. All in all, they do back up their claim of being an amazing of a solar panel manufacturer. In this SunPower solar panel review, we pretty much covered all aspects of it.

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 year.solar 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.

How Long do Lithium Solar Batteries Last

how long do lithium solar batteries last
Solar batteries are the most valuable and rewarding addition to your solar setup. Among many kinds of solar batteries available in the market, like lead-acid and flow batteries, Lithium-ion batteries are considered to be the superior choice. The return on investment in Li-ion batteries is promising, which is why many solar battery companies and EV companies are gravitating towards it.
Now the question is, how long do lithium solar batteries last? Generally, Li-ion batteries are capable of providing you with sufficient backup for 5 to 15 years, depending on the brand, build, and how you have been treating the battery. So, it’s safe to assume once you invest in high-quality solar batteries, you can expect them to be by your side for a minimum of 10 to 12 years on average.
If you are wondering about battery backup in case of a power outage or a blackout of several days, then there are many attributes to take into account in this instance. How big the battery is and what you plan to run using the battery is what will shape the figure in hours of battery backup.

Brief Discussion on How Li-ion Batteries Work

For your ease of understanding, let us discuss the battery on a cellular level in its simplest form. So, in its simplest form, Li-ion battery, the anode (negative side) is made out of graphite, and the cathode (positive side) is made of lithium metal oxide, which is the essence of this battery. Both the anode and cathode are submerged in an electrolyte which in this case is lithium salt. Also, there is a separator in between, which helps in the exchange of electrons.
how long do solar batteries last
While the entire system is up and running, positive ions of lithium flow through the electrolyte to the negative side of the system to the anode to form a bond with the carbon of that side. While this is happening, an electron gets released in the cathode side as a reaction to what’s happening as a whole. So, the lithium metal oxide is now a lithium-ion, metal oxide, and a stray electron. This is what happens at the cellular level when you are charging the lithium cell.
Now let’s see what happens when you discharge electricity from it, AKA using the battery. At this stage, the electron flows in the opposite direction, which is basically what electricity is. A load is connected at this point of discharge, and the flow of electrons keeps the battery working.
Li-ion batteries are generally considered better despite being a tad more expensive than others because they are-
  • Smaller in size
  • Easy to maintain
  • Has a greater DOD (Depth of Discharge)
  • Offers more generic cycles to go through
  • Has a longer lifespan
  • Capable of fast charging

How Long Do Lithium Battery Last in a Blackout – Solar Battery Backup

On average, every Australian household that opts for a solar battery goes for no less than a 10kW battery backup option, which can provide your family with sufficient electricity for an entire day during a power outage. Here is a breakdown of the exact kilowatt-hour usage of a lithium solar battery if used strategically throughout a 24 hours span. Click here.
But if you opt for a battery even bigger, you can go for longer without a grid connection. Off grid homes are the epitome of an example of how a battery backup, along with solar panels, works in synchronization to run a household without any utility grid connection. The battery is charging as you use it or not to form a seamless flow of electricity in such cases.

Factors that Influence Solar Battery Lifespan – Dod

solar battery lifespan
Every battery on the market has a Dod (Depth of Discharge) percentage that the manufacturer advises. Dod is the maximum amount of solar battery that can be used before it has to be recharged. The more Dod, the longer you can go without charging the battery. If your 10kW solar battery, for instance, has a 95% Dod, you may consume around 9.5kW of the electricity before plugging it back in.
You can use the entire battery at once, but you must follow the manufacturer’s instructions to keep it in excellent condition and extend its lifespan. Otherwise, this costly investment won’t provide the greatest results possible.
More and more individuals are converting to home batteries as technology improves because they are capable of storing excess energy that is produced by fully green sources like solar panels, hydropower, and wind. Being self-sufficient with a home battery is the best approach to eliminating your carbon footprint and becoming totally energy-independent.

  • Any post-installation services if needed?
  • Who do I talk to if I face any issues after installation?
  • If replacements or repairing are needed, who is going the bear that cost?
  • How long will the installation take?
  • Am I getting the benefits of federal and state rebates?
These are just the basics, and there will be more questions throughout the entire process as you go by. However, there is no alternative to good research. As this is an investment, we suggest you do tons of research beforehand and then dive in to go with a solar installer. Only then can you ask the right questions.
You can follow our regular blogs to get a good grasp of the entire process piece by piece here.

Know Your Solar System – How Does Solar Energy Work

Knowing the basics of how the solar system works will always work in your favor during the installation process and decision-making as a whole. The solar system is a package that consists of solar panels, solar inverters, and sometimes solar batteries as well.
Silicon, one of the most prevalent elements on earth, is used to make PV systems. Different silicon kinds and alignments are used to create various types of solar panels – Monocrystalline and polycrystalline solar panels. The monocrystalline solar panel, which is produced using silicon ingots rather than silicon pieces assembled into a panel like the polycrystalline ones, is the most widely used and better form of solar panel.
A solar inverter is then attached to the solar panels, converting the DC (Direct Current) power produced by the panels into AC (Alternating Current), a type of energy that can be used in your home.
solar for beginners
Your daily activities require the generated electricity, while the excess power is returned to the utility grid. In exchange for your contribution to the grid’s energy, you receive power credits that you may utilize at any time of day. A grid-tied system can always acquire electricity from the grid, just like it always did, if you don’t have enough credits or generated electricity to power your home.
The difference is that today, as opposed to in the past, you pay far less for the electricity you borrow from the grid. It’s a whole other ball game for those who have solar batteries. In that case, you can ditch the grid entirely and live on your solar system completely. Of course, in that case, you will need to have an equally excellent solar system that is not going to be cheap. But hey, you are never going to have to pay a single dime for your power bill while living a carbon-free life.

What is the Basic Cost of Solar?

The initial cost of solar depends on so many external variables if you are looking for a figure in total. But, if you are looking for prices of the panels only, $3000 is a good starting price for a quality solar panel; however, as we said before, it depends on a lot more.
For example, a bigger house requires more power, thus more solar panels to provide for the needs. A bigger family with more members to cater to will also have a greater demand for power. What about the future? Are you going to expand your family? Do you have any changes planned for the future? Let’s say in 5 years; your life can change for the better and drastically. Would the system that you are choosing right now be able to keep up with you then? Solar panels generally have a lifespan of 25 to 30 years. That is a long time, and to get the most out of your system, you have to take these little things into consideration.
As industry experts, we know the challenges of installing solar and how to work through those as we have been doing this for a good ten years. If you would like to know how you can enjoy the benefits of solar minus the hurdles, claim a free consultation session with us today.
