It is so compact, it can fit almost anywhere. A stand-alone solar system, perfect for those difficult-to-power areas.
1: Is a 20kW Solar System Suitable for My Home?
A 20kW solar panel system is best suited for lager homes, or stations even businesses with more energy-intense appliances. With the characteristics of safety, long service life, and perfect after-sales service, our products S Series will be the best choice for your household energy storage meeting your higher power needs.
An on-grid residential energy storage system can also live up your expectations of recovering the cost quickly by connecting the grid in that it allows a combination of exporting electricity to the grid and using the power in the home. In this case, you can not only produce energy you need but earn an extra profit.
Compared with an on-grid power system, an off-grid one has a high-quality component which gives you dependable grid quality solar energy all day and night. It requires a small amount of space and should fit neatly in your utility shed, or alternatively in your weather-proof and self-contained enclosure. Solar panels can be mounted on your roof or on adjustable ground frames.
As a 20kW system can produce more power, it is more expensive than the smaller ones. However, if you have higher energy requirements, it’s often quicker to pay off the cost of installation by installing a system with a larger capacity.
2: How Many Solar Panels are in a 20kW System?
The typical solar panel is 300-450 W, so if you opt for this type of panel, you’ll need to install eight to twelve panels in total to create a 20kW system (20000 W).
Below is a table showing how many panels you would need for a 20kW system, with varying power outputs:

FAQs: 20kw Solar Systems
With an off-grid solar system, you’re completely reliant on the sun and energy stored in batteries to power your home or business. If you decide to install an on-grid solar system, you will always have access to electricity from the utility grid whether or not your solar system is producing energy.
With an off-grid solar system, you’re completely reliant on the sun and energy stored in batteries to power your home or business.If you decide to install an on-grid solar system, you will always have access to electricity from the utility grid whether or not your solar system is producing energy.
If your system is not tied to a grid, you won’t receive an electric bill. However, off-grid systems are often more expensive because of the additional equipment like batteries needed. If you opt for a grid-tied system, you could still see delivery charges or demand charges on your electricity bill, even if your solar system provides 100% of your electricity
The short answer to this question is yes.
Installing battery storage systems with a 20kW solar system will enable you to use more of the energy you produce.
According to reports, installing a 20 kWh battery with your 20kW system for everyday use can boost the amount of self-generated solar power a household consumes from 30% to 60%.
That’s a considerable increase in the amount of self-generated solar power.
But whether you should install a battery depends on your budget, energy usage, and more.
If you plan to reduce your carbon footprint, save money or reduce your home electricity bills, installing a battery with a 20kW system is an excellent first step. But you should also consider the additional cost of battery installation, your payback period, and how much you are likely to save over time.
The below table shows average solar panel of per kW costs of some countries.
|Country||Cost Per KW|
Therefore, the rough cost of 8 kW solar system in Germany should be —$1113*8=$8904.
Likewise, the rough cost of 8 kW solar system in France should be—$1074*8=$8592.
There are four important factors that influence the cost of solar panels.
- Wholesale equipment costs:As a young industry, factories have been able to automate processes, increase manufacturing and logistics scale and dramatically reduce the cost per watt of a solar installation.
- compensation: In order to encourage households to select solar energy, government implements intriguing policies to attract citizens to select solar energy, such as The Solar Rebates. The introduction of local solar rebate schemes in particular states has had a dramatic effect on the cost of solar
- Competition and Cheap Solar: there are thousands of contractors to install solar. As a result, the margins have been forced to be very slim in the market.
This figure depends on where you live, your cost of electricity, your feed-in tariff, and your daily energy usage.
To determine how long it would take to pay off a system, you must calculate the total monetary value of the energy produced by the system on an annual basis, and divide the cost of the system by this figure.
You can do this by figuring out what the cost of power is, how much you will export and use in the home, and what your daily savings are.
A 20kW solar system is certainly powerful enough to cater to the average electrical needs of a 8-to-10 person household.
However, power compatibility depends on:
- Utilities and home appliances that consume energy and therefore determine the maximum power usage in your household.
- Your lifestyle. If you work at home, you’ll consume power all day, unlike a job where you can turn off the power supply until you return from work.
- Electrical vehicles you own. If you have a Tesla or plan to buy one, a 20kW solar system won’t be enough to power both the car and your household.
- Your average daily energy usage during summer and winter.
Your solar system power compatibility depends on the above-listed factors and how these align to installation in your area.
To understand if a 20kW system can power your home, you’ll divide your average daily usage by the local peak sun hour. You can find your average daily use on your electricity bill.
Average daily usage (kWh) / the local peak sun hour=Your recommended solar system size. Once again this is because a system will produce the times of the local peak sun hour its size in power per day.
If the kilowatt per hour displayed on your home electricity bill shows you consume 35 kWh per day, and the peak sun hour is 4 hours, a 20kW solar system will be enough. Anything higher than 20 kWh usage per day implies it won’t be sufficient.
A few things to consider before going solar are available space, energy needs, cost, and your overall aims for solar system installation.
A smaller system will produce less electricity than a larger system. If you’re a two-person household with low energy consumption, a smaller 5kW system will be plenty for daily use. If not, a system that will generate extra power is more advisable.
The cost is also an important factor. Since larger solar systems will cost more than smaller solar systems, payback period is affected.

How to install a 20 kW System
Most solar companies are capable of installing any size system, but you will want to choose the best solar installer in your area for the job.Many solar companies will offer a free home consultation or evaluation, or at least some sort of free estimate based on the specifics of your home. We recommend getting solar quotes from at least three companies to compare prices. And be sure to ask about any discounts, rebates, or sales the company may be offering.
