What Solar System Size Do I Need?

In order to calculate your solar system size, you will need to know:
- Your average electricity consumption, in kWh.
- The average sun-hours per day at your location.

A solar system that will produce enough electricity to account for 100% of your electricity use is calculated by dividing your monthly electricity consumption by your average monthly sun hours. You can also divide the result by 0.77 to account for expected losses in your system.
