How many solar panels do I need to power a house?
If you’re thinking about making the switch to solar energy, you’ve probably wondered how many solar panels do you need to power your house? When it comes to powering your home with solar panels, there is no “one size fits all” answer. It really depends on your location, the amount of energy that you use, and what type of system you choose.
How many kilowatt-hours do you use to run your house?
The first step to determining how many solar panels you need to power your home is to calculate the total amount of electricity you use each month. The average US household uses approximately 900 kWh of electricity per month. You can find out exactly how much energy your household uses by looking at your past electricity bills. Look for the line item that shows the total amount of energy used for the month.
Once you’ve determined how much electricity your household uses, you’ll need to convert it to kilowatt hours. For example, if a bill shows 12,500 watt hours for the month, divide 12,500 by 1,000 to get 12.5 kWh. This is the amount of electricity your household uses each month.

The next step is to determine how much sunlight your location gets each day. This is referred to as peak sun hours. The amount of peak sun hours varies from location to location and season to season. You’ll need to research the average peak sun hours for your area.
For example, if your area averages five peak sun hours each day, that means your solar panels will be able to produce five times as much electricity in one hour than they would in four hours. Knowing the peak hours of sun for your area is important when calculating how many solar panels you need for your home.
Can I run my house on solar only?
While it is possible to run your entire house on solar power, most people choose to supplement their existing electricity with solar energy. By installing enough solar panels to offset some or all of your energy usage, you can reduce your electric bill and still have access to electricity when the sun isn’t shining.
Is 10 kW enough to run a house?
Depending on how much electricity your household uses, 10 kilowatts (kW) may or may not provide enough power for your home. To determine the number of solar panels needed for 10 kW, you’ll need to do some math. A solar panel typically produces between 250 and 300 watts of power, depending on the size and type of panel. Divide 10,000 watts by 300 watts to get 33.3 panels. This means you would need 33.3 solar panels to produce 10 kW of power.
Keep in mind that this is just a general estimate. The actual number of solar panels needed to power your home will depend on factors such as how much electricity you use and peak sun hours for your location. For an exact estimate of how many solar panels you’ll need, contact a professional solar installer.
