Common installation questions

How long does solar installation take in San Jose?
There is no reliable citywide timeline. Design, corrections, equipment, financing, San Jose Building Division review, inspection, and PG&E / San Jose Clean Energy interconnection can each affect the schedule. Ask for current milestone estimates and responsibility for delays in writing.
Who handles solar permits in San Jose?
The San Jose Building Division handles permits and offers expedited processing for qualifying standard residential solar installations. The contract should identify who prepares the plans, submits the permit, responds to corrections, and schedules required inspections.
What utility approval is required from PG&E / San Jose Clean Energy?
PG&E / San Jose Clean Energy has its own interconnection process. Do not energize or export from the system until the installer confirms all required inspections and utility approvals are complete under the current rules.
Do I need to be home during the solar installation?
Access needs vary by project. Ask the installer when an adult must be present, which interior or exterior areas require access, how outages will be coordinated, and who will approve field changes.
Will installing solar damage my roof?
Any roof penetration or attachment needs a documented design compatible with the roof type and condition. Require the proposal to identify attachment details, flashing, roof exclusions, workmanship coverage, and responsibility for leak investigation. A San Jose production model should account for roof orientation, mature-tree shade, equipment, and address-specific weather assumptions.
