Assuming all of the roof space you've got is usable for solar (which, again, usually isn't the case), that's 42 panels (850 square feet divided by 20 square feet per panel). Multiplying the number of panels by the 400-watt power output of each panel gets us a system size of about 16.8 kW.
Based on this solar panel output equation, we will explain how you can calculate how many kWh per day your solar panel will generate. We will also calculate how many kWh per year do solar panels generate and how much does that save you on electricity.
Solar Power Per Square Meter Calculator. The amount of solar intensity received by the solar panels is measured in terms of square per meter. The sunlight received per square meter is termed solar irradiance.
How many square meters of solar panels do you need? Try our solar panel cost calculator if you want to work out what size of solar system you need to save money whilst being grid-tied. We’ve also written in more detail here about how to do these solar panel calculations yourself.
