Solar Design Calculator
Enter your address, draw your roof area and estimate solar size.
Use satellite view to inspect the house construction, draw a polygon on the roof and estimate usable solar area.
How this estimate works
The calculator estimates solar size from usable roof area and monthly bill. Around 100 square feet of practical roof area can support roughly 1 kW of solar capacity, but final pricing needs a site survey, shade review, inverter selection, net metering check, cable route review and battery storage discussion.
