Hiring a solar company in Poway

Solar companies in Poway file permits electronically through City of Poway Online Services, using the City's AB 2188 checklists and standard plans for expedited review; Poway reported no automated instant-permit platform to the Energy Commission and issued none of its 240 residential solar permits online in 2024. SDG&E supplies both delivery and generation, with no community choice provider. Compare at least three written bids built on your SDG&E bill.

Start with your Poway electricity bill

Poway is SDG&E territory and, unlike La Mesa or the City of San Diego, is not a member of San Diego Community Power: the Energy Commission's maps show no community choice provider over the city. SDG&E therefore bills generation and delivery, and its Solar Billing Plan puts residential solar customers on EV-TOU-5, with on-peak hours from 4 to 9 p.m. Have each bidder model that plan from your own usage.

Poway's expedited solar permit

Poway implemented AB 2188 for rooftop solar photovoltaic, solar water heating and solar pool heating systems through Chapter 15.26 of its Municipal Code. Qualifying installations are expedited when they use the City's permit application, checklists and plan information bulletins: the Poway Solar Compliance List, the building permit application, standard plans for central-inverter and microinverter systems, an inspection guide, and the California Residential Code access and pathway requirements for photovoltaic systems.

Everything is filed through City of Poway Online Services, which also holds permit records; the City has taken only electronic submittals since June 1, 2022, and payment is due when the permit is issued. Poway told the Energy Commission it has no automated SB 379 platform, and its 2024 report shows 240 residential solar permits with none issued online, so plan review is part of every Poway timeline.

An SDG&E-only bill in Poway

Many San Diego County homes now buy generation from a community choice provider. Poway's do not: SDCP's members are San Diego, Chula Vista, Encinitas, Imperial Beach, La Mesa, National City and unincorporated San Diego County, and the Energy Commission's maps show no community choice provider over Poway. SDG&E supplies generation and delivery, and its Solar Billing Plan sets the value of exports.

On that plan, residential customers are on EV-TOU-5, with on-peak hours from 4 to 9 p.m., and export credits vary by the hour and roll over month to month. SDG&E notes that pairing solar with a battery lets a home store daytime output for the on-peak hours. About 41% of Poway's 2024 permits included storage; ask each bidder to price solar alone and with a battery so you can see the difference.

What a Poway quote needs to explain

A comparison to ask for

Because Poway reports no instant platform, a bid's timeline should include plan review. Ask whether the design uses the City's standard plan, which the expedited route is built around, and whether the bidder has submitted Poway permits through Online Services recently. Then compare what each proposal leaves on your SDG&E bill during the 4 to 9 p.m. peak.
