Hiring a solar company in Fresno

Solar companies in Fresno can get a single-family or duplex rooftop permit in real time: the City uses SolarAPP+ as an express permit, so a registered contractor uploads its SolarAPP+ confirmation to Accela Citizens Access and the permit issues with no separate plan review. PG&E supplies and delivers Fresno's power. Compare at least three written bids built on your own twelve months of PG&E bills.

Start with your Fresno electricity bill

Fresno is PG&E territory for both generation and delivery; the Energy Commission's map shows no community choice provider over the city. The Public Advocates Office estimated PG&E's June 2026 average bill for customers not on CARE at $168 a month in its hot climate zone and $125 in its cool one. Since March 2026 PG&E bills have also carried a Base Services Charge of around $24 that solar does not reduce.

Fresno's SolarAPP+ express permit

The City of Fresno's Planning and Development Department adopted SolarAPP+ after testing it, and now processes eligible residential solar applications as express permits, which removes the need for plan review. The process has three steps: the contractor completes an application on the SolarAPP+ site; SolarAPP+ then directs it to the City's Accela Citizens Access to complete the permit application; and the contractor logs into its Accela account, uploads the SolarAPP+ confirmation as proof the design meets code, and receives the permit in real time.

Two limits apply. Only licensed contractors registered as installers with SolarAPP+ can use it, and only for single-family and duplex projects; commercial solar applies for a standard permit in Accela instead. If you plan to act as your own contractor, expect the standard route.

What PG&E's rules mean for a Fresno system

A new Fresno system goes on PG&E's Solar Billing Plan. PG&E enrolls residential solar customers on its Electric Home time-of-use rate, credits exports at values that change with the time of day, the day of the week and the season, and sends monthly statements plus an annual true-up. The value of what you export depends on when you export it, so ask each bidder for the hourly assumption behind its savings figure.

Since March 2026 PG&E has moved part of its costs into a Base Services Charge of around $24 a month for most customers, around $12 on FERA and around $6 on CARE, and lowered its per-kWh prices to match. PG&E's residential average was 33.7 cents per kWh in June 2026, according to the Public Advocates Office. A proposal's savings should come off the per-kWh part of your bill, with the fixed charge still there.

What a Fresno quote needs to explain

A comparison to ask for

Ask each Fresno bidder whether it is registered with SolarAPP+ and will file the express permit in Accela Citizens Access. A registered contractor on a standard single-family roof should not need weeks of plan review, so a bid that quotes a long permit wait should say why the design falls outside SolarAPP+.
