Home solar in Hesperia by the numbers

SCE approved 743 home solar systems in Hesperia in 2025, from 78 installers; the top three were named on 45% of them. The busiest year since 2021 was 2023, with 1,306 (2025: -43%). Another 382 were approved from January through May 2026.

Hiring a solar company in Hesperia

Solar companies in Hesperia can permit a new rooftop system under 38 kW through SolarAPP+ with a Hesperia business license, and the City issues the permit within two business days. A home that already has panels or a battery cannot use that route, so removing panels for a reroof or adding to a system goes through the City's regular permit. SCE supplies the power, with no community choice provider.

Start with your Hesperia electricity bill

Hesperia is SCE territory with no community choice provider on the California Energy Commission's maps, unlike Apple Valley next door, which has its own program. SCE bills generation and delivery, and its Solar Billing Plan values exports by hour and season, locks new customers' values for nine years and adds about $0.04 per kWh for eligible customers who enroll before 2028.

Hesperia's SolarAPP+ rules

Hesperia accepts SolarAPP+-approved designs for residential photovoltaic projects only, and its eligibility list is specific: under 38 kW, rooftop only, no ground-mounted or ballasted systems, no existing panels or battery storage on the home, and a supporting structure that is legal, permitted and code compliant and not historic or in a historic preservation district. Contractors need a City of Hesperia business license and a valid California contractor's license.

The contractor submits the project in SolarAPP+, pays the SolarAPP+ processing fee and the applicable City fees, and downloads the approval. Within two business days the City issues its own permit, numbered AEXX-XXXXX. Inspections are requested through the City's automated phone line, with the SolarAPP+ plans, the permit and the job card on site; a system over 15 kW gets an additional roof-mount inspection before the panels go on.

Reroofs, add-ons and Hesperia's permit numbers

Because the automated route excludes homes that already have solar or storage, the jobs many Hesperia owners search for, taking panels off for a new roof, adding panels or adding a battery, need the City's regular building permit. That usually means more time and a plan review. A reroof bid should say who removes and stores the panels, who reinstalls them and who pulls the permit.

The City's reports to the Energy Commission show a busy market: 2,379 residential solar permits in 2023, none issued online, and 920 in 2024, about 16% online and half with storage. Outside city limits, in Oak Hills and other unincorporated areas, San Bernardino County issues permits through EZ Online Permitting, and manufactured homes go to the state HCD instead.

What a Hesperia quote needs to explain

A comparison to ask for

Hesperia's SolarAPP+ route excludes homes that already have solar. If you are adding panels, adding a battery to an existing system, or taking panels off to replace the roof, the job needs the City's regular permit, not the automated one. Ask each bidder which it is filing, and for a reroof, what removal and reinstallation will cost.
