Tips
- Solar fees are charged per string ($100/string for the first 20, $20/string thereafter) rather than a flat or valuation-based fee — this is a distinct fee structure from the general building permit table.
- If you plan to add a generator alongside your solar installation, budget for a SEPARATE generator permit — the county does not combine these into one solar permit.
