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.
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.
Look at different panels and see what the wattages are. The solar panel wattage is also known as the power rating, and it's a panel's electrical output under ideal conditions. This is measured in watts (W). 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.
The average U.S. household uses about 30 kWh per day, but this varies—smaller homes might use 15–20 kWh, while larger homes with electric heating or EVs could use 40–60 kWh daily. The next step is to estimate how much energy a solar panel will produce where you live.
An average 400-watt monocrystalline solar panel will produce 2 kWh of energy per day. Solar panels with higher efficiency ratings will generally have higher wattages and are best for homes with limited roof space. The table below outlines how much energy different types of solar panels produce per month:
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.
