Zero on the Electric Bill
Photovoltaic panels are sized purely based on historical household consumption. Take your last bill and note the amount in kWh consumed in 30 days. With just this number and assuming an average solar irradiation equivalent to 5 full hours per day, our calculator exactly deduces the total load (kWp) that your house will need to install on the roof.
