Solar Panel Cost in Seaside, CA (2026): $3.06/W Reported

Seaside homeowners who bought their own solar systems reported a median of $3.06 per watt between January 2025 and May 2026, across 49 systems. The middle half paid $3.06 to $3.63 per watt.

A 3.92 kW system, the median size connected in Seaside in 2025, comes to about $12,000 at that median, or $12,000 to $14,200 across the middle half.

Those are reported costs, not a quote, and no federal credit comes off a Seaside system finished in 2026: 26 U.S.C. §25D does not cover one whose installation is completed after December 31, 2025 (state and federal rules).

What a solar permit costs in Seaside

Seaside does not publish a dollar figure for a residential solar permit. Whatever it charges, Government Code §66015 limits a city to $450 for a home system up to 15 kW, plus $15 per kW above that, unless it adopts a written finding that its cost is higher.

What Seaside publishes: The City's Solar App+ page says "A processing fee will be charged by SolarAPP+" for the automated review but does not give a dollar amount; it directs applicants to pay the separate city permit fee when applying through the City of Seaside Permitting System.
How to file: Yes, explicitly: qualifying residential PV and PV+battery-storage projects are submitted for automated review through SolarAPP+, then the SolarAPP+ approval documents are uploaded to apply for the permit online via the City of Seaside Permitting System.
Automated permit platform: SolarAPP+
