How do I know how much solar power my roof can generate?
At the end of the day, the easiest way to accurately determine how much solar power your roof can generate is to talk with installers. They design solar panel systems every day and will be able to assess your roof's unique features and provide you with a production estimate. Create your own clean energy with solar panels.
How much solar power can a 2000 sq ft roof generate?
Let's take a big 2000 sq ft roof as an example. Such a big roof has 1500 sq ft of viable solar panel area. If each of these viable square feet generates 17.25 watts of electricity, the combined 1500 sq ft will be able to generate more than 25kW per peak sun hour (25.875kW, to be exact).
Is your roof generating enough solar energy?
But also, the world isn't perfect. Realistically, your roof's solar generation potential will be less than that. It'll likely still exceed your typical household energy needs, but real-world constraints like roof space, sunlight exposure, and equipment specifications play a huge role in your panels' actual generation.
