Several factors go into figuring this out:
- How much energy you consume
- What your budget is
- Roof availability: size, azimuth, shade, etc
Here’s an easy formula to estimate system size based on your real electric usage:
- Take your highest electric usage month (for example August at 2000kWh)
- Divide that by 185. (2000 / 185 = 10.81)
- You will need roughly a 10-11kW size system to cover your peak usage with solar
We’ll go over different options and figure out together what’s the best fit for you.
