The average US home needs between 13-19 solar panels to fully offset how much electricity it uses throughout the year. This number varies based on your electricity usage, sun exposure, and the power rating of the solar panels. Use the equation below to get an estimate of how many solar panels you need to power a house.
The average American home uses about 900 kWh per month, so we’ll use that in our example: 900 kWh / 30 days = 30 kWh per day Sunlight availability affects how much energy your solar panels generate. Use NREL’s GHI maps to see how many sun hours you can expect to get in your location. Below is NREL's map for average annual sun hours in the US:
Solar panel power ratings range from 250W to 450W. Based on solar.com sales data, 400W is the most popular power rating and provides a great balance of output and Price Per Watt (PPW). If you have limited roof space, you may consider a higher power rating to use fewer panels. If you want to spend less per panel, you may consider a lower wattage.
As you plan your solar panel system, consider any anticipated increases in your home’s energy demands. Although it may be possible to add more panels later for extra costs, overcompensating for additional electricity use can help maximize your long-term solar return on investment by avoiding future labor and permitting expenses.
Yes, in many cases a 10 kW solar system is more than enough to power a house. The average US household uses around 30 kWh of electricity per day, which can be offset by a 5 to 8.5 kW solar system (depending on sun exposure). See how much solar panels cost in your area. Zero Upfront Cost.
