Solar Panel Cost in Roseville, CA (2026): $3.06/W County Median
By Chad SimpsonUpdated 7 sources citedRoseville, Placer County
Homeowners in Placer County who bought their own solar systems reported a median of $3.06 per watt between January 2025 and May 2026, across 1,915 systems. The middle half paid $2.67 to $4.54 per watt.
Roseville Electric Utility (Roseville Electric), Roseville's main utility, is not in the CPUC's interconnection data, which covers only PG&E, SCE and SDG&E. The figure above is the nearest one: Placer County homes those three utilities serve.
A 6.05 kW system, the median size connected in Placer County in 2025, comes to about $18,500 at that median, or $16,200 to $27,500 across the middle half.
Those are reported costs, not a quote, and no federal credit comes off a Roseville 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 Roseville
Roseville's published permit fee for a home rooftop system is $1,349.49 (building permit fees, SolarAPP+ route (City page)). SolarAPP+ adds a $25 processing fee; the July 2026 schedule prices PV permits from a $19,000 set valuation.
That is $899.49 over the $450 limit that Government Code §66015 sets for a home system up to 15 kW. A city may charge more only if it adopts a written finding, in a resolution or ordinance, with substantial evidence of its reasonable cost. Ask Roseville for that finding if a quote passes the fee through.
- What Roseville publishes: Roseville's SolarAPP+ page says the City's building permit fees are currently $1,349.49, on top of a $25 processing fee charged by SolarAPP+. The City's Schedule of User and Regulatory Fees, effective July 1, 2026, calculates photovoltaic permit fees from a set valuation of $19,000 rather than from the project's actual cost.
- How to file: Yes. The design goes through SolarAPP+, then the permit is applied for as a SolarAPP+ Permit in the City's online portal. The route needs Roseville Electric pre-approval, excludes main panel upgrades, ballasted systems and homes in a City flood zone, and is open only to contractors with a C-10, C-46 or B license and a City business license.

Solar data for Roseville: Roseville Electric is not covered
Roseville Electric customers are not in the CPUC data, so nothing in it describes most Roseville homes. It does list 193 systems connected in 2025 at addresses it records as Roseville in PG&E territory; those homes buy power from PG&E, not Roseville Electric.
Across Placer County homes served by PG&E, SCE or SDG&E, 32% of 2025 systems were leased or on a PPA, 34% had a battery and the median size was 6.05 kW.

Before you compare proposals
The Roseville project checks that change the decision
Roseville's electricity comes from the City's own utility, which has to pre-approve a solar system before the City permit and which buys surplus solar at a fixed rate. Both shape the value of a quote as much as its price.
Ask the same three questions
- Has Roseville Electric pre-approved the interconnection, and will the 120-day reservation still be valid when the permit is pulled?
- Does the design need a main panel upgrade? Roseville's SolarAPP+ route does not allow one, so the permit would take another path.
- Is the system within Roseville Electric's size limit, and does the savings estimate use the Solar 2.0 export rate?
Local checks
The utility approves first
Roseville's SolarAPP+ route requires pre-approval from Roseville Electric, whose interconnection reservation lasts 120 days. After the City inspection a meter technician installs a multi-register meter, and permission to operate follows.
Who may file
The City accepts SolarAPP+ applications only from California contractors with a C-10, C-46 or B license and a City of Roseville business license, not from permit runners or expediters. Homes in a City flood zone do not qualify.
Exports earn a fixed rate
Customers interconnected since October 1, 2018 are on Roseville Solar 2.0, which pays $0.0691 per kWh for surplus energy. Ask what export rate a savings estimate assumes.
Size is capped by past use
Roseville Electric limits a system to 100 percent of the customer's last 12 months of use, or the home's conditioned square footage multiplied by 3 kWh when there is no such history. The California Energy Commission's map also puts a small area at the city's northern edge in PG&E territory, so check the utility on your bill.
