Take control of your energy costs with solar power. Solar panels generate “free” electricity, but installing a system still costs money. A typical American household needs a 10-kilowatt (kW) system to adequately power their home, which costs $28,241 in 2025.
A panel will usually produce between 250 and 400 watts of power. For the equation later on, assume an average of 320 W per panel. Use your annual energy consumption and solar panel rating to calculate the production ratio. You can calculate the production ratio when you have the numbers for your annual energy usage and the solar panel wattage.
As we calculated earlier, the California household needs a 7.2 kW system to cover its electricity needs. A comparable household in Massachusetts needs a 9.9 kW system. So, in less sunny areas like Massachusetts, you might consider choosing highly efficient solar panels to maximize your energy output per square foot.
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.
Remember, you decide how much solar to get based on the need, available space, and budget. There is no rule that you have to offset 100% of current energy use. Utilities will generally allow grid-connected systems up to 120% of the previous 12 months consumption.
The goal for any solar project should be 100% electricity offset and maximum savings — not necessarily to cram as many panels on a roof as possible. So, the number of panels you need to power a house varies based on three main factors: In this article, we’ll show you how to manually calculate how many panels you’ll need to power your home.
