Your recommended solar installation size
Our recommendation is based on your bill, electricity rates in your area, and the sunlight
your roof receives.
Based on Google’s database of aerial imagery and maps, Project Sunroof knows how much
space on your roof can fit solar panels and where is best to install them.
Solar panel installations sizes are measured in kilowatts (kW).
We recommend an installation less than 100% of your electrical usage because, in most
areas, there is no financial benefit to producing more power than you can consume. Sizing
below 100% provides a buffer in case your electricity consumption decreases over time.
