Quick answer
The practical explanation
A good candidate generally has a roof or mounting area with useful sunlight, manageable shade, adequate structural condition, and enough space for a practical array. Electricity use, local utility rules, and how long you expect to stay in the home also matter.
What to know
Three points to keep in mind
- Roof age and condition should be reviewed before installation.
- Trees and nearby structures can materially change production.
- A site-specific assessment is more reliable than a satellite image alone.
For your home
A site-specific answer still matters
Solar results and service needs depend on the roof, equipment, shade, household electricity use, utility requirements, and the condition of the existing system. Use this guide as a starting point, then have the property and equipment evaluated before making a major decision.
