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.
You can calculate how many solar panels you need by dividing your yearly electricity usage by your area''s production ratio and then dividing that number by the power output of your solar panels. To put it simply: Number of panels = annual electricity usage / production ratio / panel wattage
There’s no maximum number of solar panels you can install, so it''s just a matter of how much space you have. With a large system, you’ll generate excess electricity that you can sell to the grid. Export tariffs can already earn you hundreds of pounds per year, and they''re getting increasingly profitable.
