How Much Power Do I Need to Live Off Grid

how much power do i need to live off grid
Our energy demands increase with the advancements in science and technology. This growing demand led us to rely more and more on the grid electricity but depending on burning fossil fuels is a surefire way to trigger global warming. That’s why going off the grid is becoming popular, both in an attempt to save nature as well as ditching the ever-growing energy prices.
With off grid living comes the concern of meeting the power demands. Many of us do speculate if an off the grid solar system will be able to meet the needs of my family or how much power do I need to live off grid. It’s absolutely possible to live off the grid and power an entire village let alone one family; that’s one thing I can assure you of; however, how much power would you need to live off the grid is a decision that has to be tailored to your needs at a price you can afford.
Here is how you can summarize and understand how much power you might need to live off the grid.

Know The Energy Pattern of Your Household

Firstly, observe your everyday life and document what are the things you tend to use most. It’s best to take into consideration different seasons, as in winter, you may not need to use the air-con as much as you would in the summer.
In a typical household which, for example, let’s say is a family of four, the daily power consumption pattern may look like this- for heating and cooling purposes, the family uses 35% of the energy available for lighting up the house, about 7%, for hot water about 22%, for computers, styling tools, pool, dishwasher, other appliances about 20% and for other miscellaneous usages the rest of the energy is used.
For this particular family, it can be assumed that they use about 38kWh to 40kWh of energy a day without any alternative source of power. Please know that this is not a definite number but an illustration.
So, if your family’s energy consumption pattern looks anything similar, you can expect to go for a system of that size when you decide to go completely off the grid. In reality, people tend to shy away from using a lot of energy in fear of scarcity while living off the grid, but if your system is sized correctly, you don’t need to miss out on anything ever again.

Analyze Your Current Power Consumption

Above was speculation about the energy needs of a typical Australian household. But you can get legit numbers if you take a look at your quarterly energy bills. Usually, there is a usage pattern and count given in the bill paper along with the average daily kWh use.
That is also not a definite number but an idea of your pattern. Depending on these factors, you can get your off the grid solar house designed to perfection.
Remember that it’s always a good idea to go up a size while designing the solar system rather than expecting to limit your energy consumption if need be. Along with situations like suddenly needing a bit more electricity than usual, you can also expect your solar panel system to sometimes yield lesser than expected. This could happen because of the weather, lesser peak solar irradiation, shading issues, dirty solar panels, and a number of other reasons.
By upsizing the solar system, you can make sure to have an ample amount of energy to be at your disposal and go without generating solar energy for at least a couple of days.

How Many Solar Panels Do I Need?

How many solar panels you would need to live off the grid depends on a number of variables which are-
  • Your daily average electricity usage
  • Amount of roof space you have
  • If your choice of installation area (can be roof or ground mounted system) has shading issues
  • Daily solar irradiation in peak and off-peak hours
  • The type of solar panels you choose
However, your energy needs and the output of each solar panel are the two core elements that determine the number of solar panels you will need to go off-grid.
Standard testing settings are used to assess panel performance. These circumstances include 1,000 W/m2 of solar radiation, AM 1.5 of the solar spectrum, and a 25 °C module temperature.
Typically, a panel’s performance increases with size. A 100-watt solar panel, for instance, is normally 47 x 21,3 x 1,4 inches in size. The size of a 200-Watt solar panel is 64 x 26 x 1.4 inches (rough projections). More photovoltaic cells can be put inside of a larger framework, increasing their performance here forth.
Also, if you choose to go for monocrystalline or polycrystalline panels is a deciding factor in this matter. Polycrystalline panels being inferior to monocrystalline ones, will require you to install more in numbers. One pro in favor of polycrystalline panels is that they are cheaper.
In short, if the solar panels are made from fragments of silicon or ingots of silicon is the core difference between the two types of solar panels; monocrystalline ones being from solid chunks of silicon and polycrystalline ones from fragments of silicon.
To be more precise about the whole ordeal, it is highly recommended you consult with a solar expert approved by the CEC. Learn more about off grid solar systems here.

Benefits to The Environment of Going Off Grid

benefits to the environment of going off grid
In Australia, 33.6% of total emissions come from burning fossil fuel. Why is burning fossil fuel essential, you may ask? It’s needed to generate electricity. So, that proves a massive amount of environmental harm comes from our high dependency on grid energy which can be catered for with other renewable sources like solar, wind, hydro, etc.
On the flip side, going off the grid means eliminating that dependency on grid energy, ultimately lesser fossil fuel combustion each year. Off grid living facilitates the lifestyle of ultimate energy independence, leading to a more environmentally friendly lifestyle. Not only this, but there are also many other benefits of living off the grid.
Here are some of the benefits to the environment of going off grid discussed in brief –

Fight Against Global Warming

Global warming is more prevalent now than ever. As we gravitate towards grid electricity because it’s easy, we are indirectly facilitating the giant electricity retailers to burn more fossil fuels. This repetitive practice has increased the greenhouse gases in the environment. As a result, the heat of the sun gets trapped in the atmosphere, and the temperature rises significantly. This phenomenon is called global warming.
It is granted that not just the electricity retailers are solely responsible for this, all the other major corporations, especially manufacturing facilities, are also contributing to the problem. However, almost one-third of the GHG emission comes from fossil fuel burning, and none other than the energy retailers are to be blamed.
climate change and off grid living
If you choose to live off the grid, you can fight against this by opting for renewable sources of energy. Sources such as solar panel systems, micro hydro energy, and wind energy are some of the ways many people generate power off the grid. Find out more about how you can generate power off grid here.
These are clean power sources for your household, limiting your carbon footprint remarkably.
Not only will you not be emitting harmful gases, but also you can become completely energy independent. This means no power cuts during storms and no power cuts during maintenance at an odd hour.

Become Energy Efficient

As mentioned above, living off the grid will make you completely energy independent, but this also gives you the opportunity to remodel your surrounding in the most energy-efficient way possible.
For instance, you may reduce the likelihood of heat loss and add additional insulation by changing the foundation, form, and architecture of your house. Your dependence on energy and other heat sources will decrease, as a result, allowing you to satisfy your demands with a much smaller solar or wind power system.
  • Installing solar is the easiest of all renewable energy systems.
  • Solar panels are cheaper in comparison to grid connections.
  • It’s a reliable source of power that requires little to no maintenance.
  • Transporting solar and solar equipment is easier.
  • Within a few years, a well-designed system may pay for itself and offer a good ROI.
  • If problems arise, they are quite simple to resolve and, for the most part, do not require professional guidance.

benefits of solar energy to the environment

No More Fossil Fuel Burning

Burning fossil fuel such as coal is one of the core reasons why we are suffering from the drastic effects of climate change. The sea level has risen about 8 to 9 inches since the 1980s. These changes will become faster if we don’t take proper measures as soon as possible. Going off grid is one of those measures that we can take.
It’s ultimately the energy we consume to carry out everyday chores that do the most damage. When you choose to live off the grid, you are carrying out these everyday chores, not at the expense of the environment. Rather power sources like solar can give you essentially free energy for the rest of your life (at least the next 25 years) on top of being completely clean.

Recycling & Upcycling- A Sustainable Habit

You may develop the practice of recycling and upcycling if you live off the grid. It is conceivable in any sort of living situation, but they become simpler if you have access to a large property. For instance, many people who live off the grid make use of the property by setting up recycling areas where they can turn food scraps into compost. Additionally, there are many opportunities for upcycling as it is not as simple to dispose of what we generally regard to be rubbish in this situation. Using a pickle jar as a cookie jar or flowerpot, for instance, is upcycling.
Growing your own vegetables and herbs is another fantastic option for lowering your carbon footprint. As you grow your own food, you become less dependent on large-scale producers, who actively contribute to GHG emissions by utilizing expensive machinery and equipment.

How To Generate Power Off Grid

how to generate power off grid
If you are looking forward to starting to live off the grid, sorting through different options for power generation is extremely important. There are many stand-alone systems that can generate energy for your household which are completely green, sustainable and carbon emission free. Although all these options may seem attractive, you are going to have to make the call to choose the one that is suitable for your house, keeping all the other aspects in mind.
The article is intended to help you through the process. On that note, here’s how to generate power off grid explained.

Different Renewable Energy Sources for Your Home

As we are mainly looking into powering a residential property or a small farm or business, this suggestion will strictly be catered to that. Solar emporium does not favour the non-renewable options of power generation for any off the grid property because of the extreme effects on the environment happening right now.
To power your off the grid home, you can choose the following power generation options (renewable)-
  • Solar panel system
  • Wind electricity
  • Micro hydro electricity

Solar Panel System

There are many ways to be energy independent and have no carbon footprint, like using wind and water electricity, but the process is time consuming and needs ongoing maintenance. A residential off-grid house that uses a power source other than solar is therefore uncommon. Without much effort on your part, solar energy can give your house the constant electricity it needs to run and store some more.
Wondering how solar panels work? Solar panels function by reacting when sunlight strikes them. The amount of energy generated depends on the angle and intensity of the sunlight, but solar panels will continue to produce energy for as long as they receive sunlight. After that, a solar inverter transforms it into useable electricity, which you may use to power your house.
off grid solar panels
In an off grid home, you are required to have solar batteries tied to the system. This way, you can reserve the surplus of energy generated by your panels to use later. Also, a charge controller is essential, which can determine the flow of electricity either to the house or the battery, also control when to switch to the backup generator if required.
Kilowatts, or kW, are the unit of measurement for a solar system’s power rating. It is a measurement of the size of your solar system, not the amount of energy it will generate. The size of your system (x kW) is multiplied by the Peak Sun Hours unique to your area, which vary between summer and winter, to get the kWh (kilowatt hour). The generated energy, measured in kWh, will initially be used to power the house’s daytime loads before being used to charge the battery bank.
Solar panels are the ideal choice for your off grid home among the other power generation alternatives.
Here is why-

Advantages of Solar Power

  • Easy installation process.
  • Requires little to no maintenance and labour.
  • Solar panel prices are dropping at an astonishing rate with recent technological advancements.
  • Government rebate under the Renewable Energy Target (RET).
  • A well-designed system can provide excellent ROI and pay for itself within a few years.
  • No additional establishment is required to maintain the system.
  • Sustainable and independent energy source.
  • Fixing any issues, if faced, is extremely easy and can be done without any expert supervision in most cases.
  • Does not require any additional connection fees or permissions.

Areas to Improve

  • If solar panels could work at a 100% efficiency rate, the entire world could be powered by only 1 hour of peak sunlight hours. Which is a rather imaginative scenario but the system’s efficiency can always approach growth.
  • With scientific revelations and effective supply chain management, the prices of a solar panel system have the potential to drop even more.

Wind Electricity

This is another option to generate power off the grid. It might not be the most feasible option if you do not have a lot of space in your off grid property. However, a 5 to 15 kW system is sufficient to provide for an average household’s monthly electricity needs. The efficiency rate of a wind electric system depends on the wind speed of the area, which can vary in different seasons.
A typical wind electric system which is enough to generate power for a single residential house can be at least 23-25 feet in diameter and 100 feet tall.
The rotor blades of a wind turbine, which function similarly to a helicopter rotor blade, convert wind energy into electricity using aerodynamic force. The air pressure on one side of the blade falls as the wind passes by. Both lift and tug are produced by the different air pressure on the blade’s either side. The rotor spins because the force of the lift is greater than the force of the tug.
If the generator is a direct drive turbine, the rotor is connected to it directly; otherwise, a gearbox that speeds up the rotation and permits a physically smaller generator is used. Electricity is produced as a result of the conversion of aerodynamic force into generator rotation.
micro hydro energy renewable

Micro Hydro Electricity

As the name suggests, the micro hydro electricity generation system requires water, a steady flow or stream of water. Using the kinetic force of a water stream micro hydro system can produce electricity to power any off the grid residential property. These off grid systems are usually the cheapest solution for any off grid home but with that comes some difficulties as well. It’s a high-maintenance system that requires quite a lot of attention.
Besides that, this is the most cost-efficient green energy source that can run 24/7 if designed properly. There are many commercial power plants that run on hydro electricity using a massive water stream, either man-made or natural, but a micro one is a miniature version of such systems.
The impact of the high-pressure water on these cups rotates an alternator, which produces energy. Batteries are typically charged by the alternator.
Maximum electrical output for hydroelectricity is determined by the formula: flow rate (litres per second) x head (meters) x 10. (watts). Therefore, a stream descending at 20 litres per second down a 10-meter head would have a 2000-watt maximum output.

Off Grid Solar Power Simplified – Off Grid 101

off grid solar power simplified
An off the grid solar system is simply a set-up that is not connected to any utility grid; thus, it’s an autonomous solar system that can generate enough power for an entire household, small office, or farm etc. However, putting together some panels and inverters without any prior assessment is a sure-fire way to waste money in exchange for a lousy PV module.
That brings us to today’s topic, how does the off grid system work in its true essence and how you can get the most out of it? Here’s off grid solar power simplified for your convenience, take a look.

What Is an Off Grid System Comprised Of 

There are 5 main components that work together to create an excellent off the grid solar system.
off grid solar system
Solar Panels– Solar panels, also known as PV modules, are the ones responsible for capturing sunlight and generating direct current, which is essentially electricity in its raw format. How much sunlight can the panels capture and effectively convert into electricity depends on module quality, quantity, amount of sunlight exposure, roof angle and geo-location.
Solar Inverters– The solar panels have generated electricity in the DC format, and that remains unusable until its run through the solar inverter. It converts DC into AC (alternating current) for the appliances to use and operate. There are many types of solar inverters, some of which are even capable of storing energy for later use. In an off grid house, you will be using a standalone inverter which is not connected to the grid.
Solar Batteries– Solar panels are designed to operate using the power of the sun, but for a majority of the households in Australia, electricity is most needed in the evening hours or at nighttime. To store the surplus of energy generated at midday (the most optimum solar hours), you will need solar batteries. It’s an essential component for an off grid solar system.
Solar Charge Controller– It’s not a feasible arrangement if you always have to manage the energy flow in the correct direction. To aid in that issue, a charge controller is necessary. It controls the direction of energy flow to the correct path according to the situation and prevents the solar batteries from overcharging, essentially extending their life.
Backup Generator– If all things go south, a diesel-powered backup generator will come to your rescue. It is not an everyday event with a quality system, but on the off chance you do experience a power outage through solar, it’s best to have an off grid solar system with a backup generator.

Why Go Off the Grid?

Off grid solar is not for everyone that is true. But if you look at the electricity price hike in recent years, it makes total sense why people chose alternative energy sources like solar, wind etc., over the grid.
Because of the changes that happened on July 1st 2021, this year by the Australian Energy Regulator, using grid electricity has become more expensive when it’s a fact that this entire procedure actively participates in GHG (Green House Gas) emission.
Check out the exact price changes for the 2022-23 financial year here- Click me.
Besides the negative impact on the environment and increased prices of energy, it’s not a lucrative option for you to choose grid connection if you live in a remote area. While it almost costs a fortune to pay for a grid connection in remote areas, you will have to pay a hefty amount in electric bills each year.
On the other hand, choosing an off grid solar system will cost you less than a grid connection, and after installation, you will never have to worry about paying electric bills again (not at least in the upcoming 25 years). Not to mention the freedom over the system as well as the serenity that comes from living amid nature.

Pro-tips: Off Grid Solar System Basics

Here are some of the facts that you need to know before you go off the grid, along with some tips from our off grid solar experts-
  • It’s almost always better to upsize the solar system. As you will be living off the grid, an essence of uncertainty can make you nervous; we are only human. So, experts suggest you upsize your solar system to the point where you can go without charging your batteries for at least 2 days if necessary. You might not need it, but it doesn’t hurt to have it.
  • MPPTs (Maximum Power Point Tracker) are important. Your solar panels might struggle to operate at their maximum efficiency without MPPTs. For an off the grid solar system, its essential that you get the most out of your system, so it’s suggested that your system has MPPTs, yup multiples of them.
  • Some might say that cleaning your solar panels does not do much, but experts may tell you otherwise. It has been proven in many studies that not cleaning your solar panels can decrease their efficiency by up to 30%. So, please do keep your panels clean. Here is how you can clean your panels yourself- How to clean solar panels.
  • Be very aware of the local government rules and regulations. Different councils may have different legislations; you must be aware of them along with any changes while in the process of shifting to your off grid property. Your chances of claiming the government rebate depend on it. Learn more here.
Going off the grid is not only an attractive option for those who live in a remote area but also for those who are experiencing an unexpected surge in power bills.

How to Live Off the Grid | Off Grid Living 101

how to live off the grid
With the ever-rising cost of living in Australia, living off the grid is becoming more and more popular every day. However, it can be challenging to live off the grid for some. It requires you to follow through with certain procedures and be consistent with them.
Let’s jump right into how to live off the grid and sustain the lifestyle.

Double Check Legal Matters Before You Go Off the Grid

There are two ways you can go by when deciding to go off the grid.
First, you can convert your current residence into an off grid system. Technically, off grid living means cutting off your reliance on the power grid that is used by mass.
As energy prices are at their peak at the moment and it only seems to be getting worse, you can cut off your reliance on the public shared grid and generate your own power through sustainable and renewable sources like solar, wind, water, etc.
Before you do that, you will have to check with the authorities as different councils may have different regulations in place. Also, when you decide to go for certain renewable energy sources like solar, you may be eligible for government rebates for an off grid solar system as well. Make sure you explore all the benefits of off grid solar living like the rebates or consult a solar expert.
legal regulations for off grid
The second way to live off the grid is to relocate. That comes with a completely different set of challenges, as not only power, but you may also need to build every repetitive cycle management like power generation from scratch. There are many remote locations in Australia that do not need a permit to live or build; you can relocate to those areas to build your own sustainable lifestyle
In short, there are three aspects in which you need to look out for in regard to legal obligations, which are-
  • Zoning and housing permits
  • Land allocation and ownership
  • The government provided rebates and incentives
Keep in mind that relocating somewhere remote does give you complete freedom and being one with nature may seem tempting. However, if you are heavily reliant on city life and the convenience of a town, this might just not be your call.

How to Live Off the Grid- Essentials 

Without some basic essentials living off the grid is impossible. Here is a list of things you need to think about before you go ahead with the decision-

Daily Nutrients- Food and Fresh Drinking Water

It goes without saying you will need food and fresh drinking water to survive. When living in a remote area, you will not have easy access to them, so it’s better to stock up. But that is not a permeant or sustainable solution. It’s best if you do your own farming for fresh veggies, herbs, and livestock. Also, collecting rainwater and a deep well can be your source of fresh drinking water.
government rebate for off grid

Power Generation – A Sustainable Power Source

This is a major undertaking and could be the most crucial part of living off the grid. There are numerous methods to be energy independent, leaving no carbon footprint, such as using wind and water, but the process is labor-intensive and requires constant upkeep. As a result, you are unlikely to find a residential off grid home that uses any other power source beyond solar. Solar energy can provide your home with the constant electricity it needs to function without much work on your part.
  • How does off grid solar system work?
Solar panels, solar inverters, inverter chargers, battery banks, and backup generators are the key components of an off grid solar system. How do all these elements combine to form the ideal off the grid home?
First, when sunlight strikes the solar panels, a photovoltaic reaction occurs, producing energy. The quality of the panels will determine how much power is produced in “x” duration. The solar inverter transforms the produced power into a useful type of energy after that. To put it simply, the electricity produced by the panels is DC (Direct Current) electricity; however, what we want is AC (Alternating Current). This conversion gets handled by the trusty solar inverters with 99% efficiency in the best cases.
After use, the extra energy is kept in the solar batteries. However, there is a catch—the battery bank can only be used to store DC. In order to do the reverse conversion and communicate when to stop the conversion and run it the other way, a charger inverter is used. On the rare occasion when your batteries run dry, you may resort to diesel generators.

Hot Water Supply 

Water heating is the second largest energy-consuming task in the residential sector in Australia. That means you will have to ensure an off the grid heating system that runs without the help of traditional coal-burning grid energy. There are some pollution-free and sustainable solutions like a heat pump for your hot water needs that needs less electricity to run, and production gets multiplied with their use.
Check out some energy-efficient water heating systems here.
Also, there are solar hot water systems that runs using the power of the sun. They are energy efficient and do not emit any harmful gases. Aside from these hot water systems to rely on, you can always opt for a handy wood stove, but convenience is questionable in this method.

Waste Management 

This is something that you would think is easy to manage; however, it’s quite a chore to manage. An off the grid house does not have a central waste management system access provided by the government, so in order to manage your waste and grey water, you will have to build a cohesive system that takes care of it efficiently and hygienically.
You can turn your food wastes into self-made compost in this manner; your waste can become your resource.

Do People Live Off the Grid in Australia?

Definitely! There are communities like Chewton Bushlands that have lived off-grid for decades if you’re seeking for like-minded people who have cut themselves off from the grid. Additionally, organizations like the Cohousing Australia Initiative and Tiny Homes Australia provide in-depth instructions on how to live off the grid.
In conclusion, living off the grid is challenging yet rewarding, and as time passes by, more and more people are opting to live off the grid for its convenience. Talk to an expert today to know more about how to live off the grid.

What is the Best Off Grid Solar System

What is the Best Off Grid Solar System
There are 5 main components that make up a perfect off the grid solar system. Here is what makes up an off grid solar system
Solar Modules: In solar modules, photovoltaic conversion transforms solar energy into usable electricity (DC).
PV Inverter: To use in the house or to charge the battery bank, a solar inverter transforms the DC electricity generated, into AC.
Charger Inverter: This device converts AC power to DC so that it may be stored in batteries for later use. A battery bank is only able to store energy in DC.
Battery Bank: To store the power produced by the modules for later usage, lithium-ion batteries can be used. However, lead-acid batteries and nickel cadmium batteries are also used to achieve the same goal.
Backup Generator: Just on the off chance there is no stored energy in the battery bank, a diesel generator is used as a backup power source if needed.

How Does it All Work?

How do all these components come together and create the perfect off the grid house?
Firstly, the solar panels generate electricity through a photovoltaic reaction when sunlight hits the solar panels. The amount of electricity generated in ‘x’ amount of time will depend on the quality of the panels. Then the generated electricity travels to the solar inverter to convert into a usable form of energy. To explain that, in simple terms, the energy generated in the panels is DC (Direct Current) electricity and what we need is AC (Alternating Current) electricity.
After the conversion, the surplus amount of energy gets stored in the solar batteries. But there is a catch; you can only store DC in the battery bank. And this is where the charger inverter comes into play to do the conversion and also send signals across when to shut off the conversion and run it the other way.
With all that being said, there can be extremely cold days when the sun does not shine, and your solar panels can’t process to render a surplus for you to use later. In these rare occasions, you just might want to be safe with a backup generator that runs on diesel.
And that is about it, on how an off grid solar panel system works.

Different Types of Battery for Solar Energy Storage

Are you searching for the best batteries for solar off grid? Here are a few different types of batteries popularly used for solar battery storage-

Lithium-ion Battery

Li-ion batteries have a variety of benefits over the other premium rechargeable battery technologies (nickel-cadmium or nickel-metal hydride). The energy density of these batteries is among the greatest available (100-265 Wh/kg or 250-670 Wh/L). Additionally, compared to Ni-Cd or Ni-MH battery technology, Li-ion battery cells have a voltage output of up to 3.6 Volts. They can thus supply substantial current for high-power applications.
Li-ion batteries are also portable, and their high DOD (Depth of Discharge) allows you to draw out more energy without threatening the battery life. They require a small space to sit and provide you with a huge power load in comparison to other batteries.
It is also popularly used in many cases alongside solar energy storage because of its usefulness and reliability.

Lead Acid Battery

These batteries are tried and tested veterans of the category. The most popular battery type in solar systems is the lead acid battery. In contrast to other battery types, lead acid batteries have a longer lifespan at a reasonable cost. There are two types of lead acid batteries which are –
  • Flooded lead acid battery
  • Sealed lead acid battery
Of the two types, sealed batteries are used for the most part because the flooded ones require constant maintenance; even so, you risk leaking. With a low DOD and high maintenance, sealed batteries are more often chosen over flooded ones.

In order to find the best battery for your off grid solar home, you will need to look for the following attributes in your battery of choice-

Depth of Discharge

DOD signifies a battery’s capacity or energy held in them. Manufacturers provide you with a number in the form of dod below which your battery level should not drop down if you want to elongate its lifetime. This is one of the most important attributes that you need to know about. Remember, the higher the DOD, the better the battery is, and it will serve you for a longer time.
Usually, li-ion batteries provide a higher DOD than the lead acid batteries, which usually do not go beyond 80%. It’s essential to follow the manufacturer’s advice in this case.


It is usually advised to upsize your off grid solar system so that you can yield more energy and keep that at your disposal. Also, to future-proof the house, you are required to upsize your solar system. In this case, you will also have to consider the capacity of the battery. Your solar system’s electricity generation ability should be on par with the battery.
Review your previous bills and know how many kilowatt hours of energy did you need on average. This will give you an idea of what capacity battery you will require. My advice would be to leave a little wiggle room and estimate a bit higher than you need just to be on the safe side.


As your typical solar system comes with almost 25 years of official warranty, the solar battery of your choice has to suffice for that. Typically, solar batteries come with 10 to 15 years of warranty, depending on some criteria. You have to be careful when you choose your battery for your off grid home and abide by the manufacturer’s advice for prolonged battery life.
