How Much Energy Can Solar Panels Produce?

Your rooftop may generate power and give you energy independence with solar panels. With today’s climate extremes and obsolete electrical grid, your rooftop also provides peace of mind. So, before you go solar, figure out how much power your roof can generate.


There are several equations for estimating how many solar panels and how much power a family needs. As an example, consider the following: 

  • The average family in the United States needs a 6.62-kW solar system to meet their annual energy use of 9,000 kWh. A typical solar panel generates 320 watts of electricity in optimum sunny conditions. 
  • Divide 6.62 kW (system size) by.320 kW (wattage per panel) to get 20.69 panels (rounded up). Even if your house isn’t typical, this is how you can come up with a reasonable estimate.


Several factors determine the ideal solar system size. Your home’s energy usage, the available square footage on your roof, the solar panel wattage, and the amount of sun the solar panels will receive are just a few of these variables.

Where the sunshine is scarce, homeowners prefer higher-rated panels that produce more electricity than panels normally chosen for homes in sunny areas. High-efficiency panels create more energy for all dwellings, resulting in fewer panels on your roof.

Solar panels are rated according to how many watts they produce. The higher the wattage rating, the more power your solar panel system will generate. The power output ratings of most home solar panels range from 250 to 400 watts

This depends on panel size and how successfully they convert sunlight into energy. While greater power ratings are preferred, power output is not the only thing to consider when evaluating the performance of a solar panel.
