What a Santa Rosa quote needs to explain
| Check | Ask each bidder |
|---|---|
| Reroof coordination | List removal, storage, attachment details, reinstallation and the responsible businesses. |
| Solar enrollment | Identify SCP and PG&E treatment for an existing system before changing the array. |
| Backup design | Ask for named circuits and runtime assumptions; price backup capability separately from bill savings. |
A comparison to ask for
Suppose a roof replacement is due and a solar salesperson prices only the new array. Request a combined scope that names who removes the old equipment, makes the roof watertight and reinstalls or replaces the system. Ask which company handles a leak claim after the work. That gap can erase a price advantage.
Verify the company behind the Santa Rosa quote
Match the business name and license number on each Santa Rosa proposal to the CSLB record, then use our contractor verification steps, the quote comparison guide and the PPA, loan, lease and cash comparison. What you pay the utility today is on the Santa Rosa rates and bills page.

Santa Rosa solar quote questions
Can solar be put back after a Santa Rosa reroof without documenting it?
The city’s current permit guidance calls for panel layout and attachment details for removal and replacement, including panels returned to the same location. Have the bidder include that work.
Will adding a battery back up every circuit?
The equipment and wiring determine what can run. Request a circuit list, reserve setting and load-based runtime estimate for the proposed design.
