Do I Need a Permit for Solar Panels in San Bernardino, CA?

San Bernardino's solar story involves a tension of factors that makes it one of the most interesting cities in this guide for solar economics. On the resource side, the city is exceptional: Climate Zone 10's intense sun delivers peak sun hours among the highest in California — typically 5.5–6.2 peak sun hours per day annually, compared to 4.5–5.0 for coastal California and 3.5–4.5 for the Pacific Northwest. A solar panel in San Bernardino produces significantly more electricity per installed watt than in Fremont or Tacoma. On the policy side, Southern California Edison's NEM 3.0 (Solar Billing Plan), like PG&E's NEM 3.0, drastically reduced export credits in 2023, making self-consumption strategy critical. And on the permit side, California Senate Bill 379 now mandates automated permitting through the Symbium portal for systems under 38.4 kW — a substantial improvement over the older in-person plan submission process.

San Bernardino solar permit rules — the basics

California Senate Bill 379, signed in September 2022, established statewide requirements for automated, online solar permitting for residential systems under 38.4 kW. San Bernardino complies by implementing the Symbium automated portal, which the city's Solar Permit page describes as follows: "Contractors and homeowners seeking to pull permits under SB 379 may apply for instantaneous plan review approval through the Symbium portal." The Symbium portal performs automated code compliance checking of the solar system design — verifying fire access setbacks, structural loading, electrical specifications, and equipment eligibility — and generates permit documents that are then uploaded into San Bernardino's Citizen Access permitting portal for the final permit issuance. The city's Solar Permit page estimates processing time of approximately 1–3 business days after complete submission.

The panel upgrade exception is important. San Bernardino's Solar Permit page notes: "Electric Panel Upgrades will require a separate electrical permit. Electrical Main Panel upgrade permits associated with solar can be obtained by contacting the Solar Division of Community Development and Housing" at solar@sbcity.org. If your solar installation requires upgrading from 100A to 200A service to accommodate the new inverter and loads, that panel upgrade is a separate permit track from the solar permit itself, coordinated through the dedicated solar team.

For systems not eligible for Symbium processing — either because they exceed 38.4 kW, use non-eligible equipment, or have unusual configurations — San Bernardino offers an alternative path. Systems 10 kW and under that meet the city's Eligibility Checklist for Expedited Residential Solar Permitting can be submitted in person at the Building and Safety counter with a one-page plan set. Systems that don't qualify for either automated or expedited processing use the standard plan review path, which can take several weeks.

Southern California Edison's Solar Billing Plan — commonly called NEM 3.0 — governs how excess solar production is credited for San Bernardino residents. Like PG&E's NEM 3.0 that applies in Fremont and Santa Clarita, SCE's Solar Billing Plan replaced retail-rate net metering (NEM 2.0) in April 2023. Under the Solar Billing Plan, solar export credits are calculated at an "avoided cost" rate that is significantly lower than SCE's retail electricity rates. The practical effect is similar to what Fremont homeowners experience under PG&E NEM 3.0: exporting excess solar to the grid yields much less financial benefit than using that solar directly in the home. Battery storage, EV charging during daylight hours, and running high-load appliances during peak solar production hours are the strategies that optimize solar economics under the Solar Billing Plan.

Three San Bernardino solar scenarios

San Bernardino's solar resource and SCE NEM 3.0 economics

San Bernardino's Climate Zone 10 delivers exceptional solar production. The San Bernardino Valley receives approximately 5.5–6.2 peak sun hours per day on an annual average — among the highest in California, exceeding the Bay Area's 4.5–5.0 and dramatically exceeding the Pacific Northwest's 3.5–4.5. A solar panel in San Bernardino produces 20–40% more electricity annually than the same panel installed in Fremont or Tacoma. This production advantage is important context for SCE's NEM 3.0 economics.

Under SCE's Solar Billing Plan (NEM 3.0, effective April 2023), solar export credits are calculated at avoided-cost rates — approximately $0.05–$0.08 per kWh — rather than the retail rates of $0.25–$0.40 per kWh that applied under NEM 2.0. This 70–80% reduction in export credit value significantly changes the economics of solar in San Bernardino. However, San Bernardino's production advantage matters: a system generating 50 kWh/day in peak summer can serve a household using 30 kWh/day with only 20 kWh of exports at the low avoided-cost rate. The 30 kWh of self-consumed solar still offsets retail electricity at full value.

The financially optimal solar strategy in San Bernardino under NEM 3.0: size the system to match the household's annual electricity consumption without significant excess export, and use daytime loads — EV charging, pool pumps, air conditioning — to consume solar production directly. Households that already have EVs or are planning to electrify heating and cooling benefit most from solar in San Bernardino's market. Battery storage further improves economics by shifting stored solar to the SCE evening peak rate period, avoiding high retail rates for the 4–8 pm period when SCE's time-of-use rates are highest.

What solar installations cost in San Bernardino

San Bernardino's solar installation costs are moderate in California's context — lower than the Bay Area but in line with the broader Southern California market. System costs run $2.70–$3.80 per watt installed. An 8 kW system: $21,600–$30,400; after 30% ITC: $15,120–$21,280. A 9 kW system with 13.5 kWh battery: $35,000–$52,000; after 30% ITC: $24,500–$36,400. Permit fees for Symbium-path residential systems are included in the project pricing from most contractors. California contractor: verify CSLB Class C-46 (Solar) or C-10 (Electrical) at cslb.ca.gov; City of San Bernardino business license required.
