Am I eligible for solar funding in California?

Eligibility in California depends on your household income, property EPC rating and council tax band.

Your MCS installer will run a quick eligibility check during the free survey.

How long does a solar installation take at a California property?

A typical domestic solar installation in California (IP4) is completed within one to two working days. Adding a battery normally extends this to two or three days. You stay powered throughout, and the final grid connection takes only a short period of safe isolation.

Do I need planning permission for solar panels in California?

Most domestic installations in California fall under permitted development rights, so no planning application is required. Listed buildings, properties in conservation areas and schemes that protrude more than 200mm from the roof line may need local authority approval. Your MCS installer handles the checks and any submissions.
