Commercial Solar & BESS · Riverside & San Bernardino Counties
From Ontario, Rancho Cucamonga, and Corona logistics centers to Riverside (RPU), Temecula, and Coachella Valley (SCE & IID) commercial properties, OC Solar engineers and builds turnkey rooftop solar, carports, and battery storage backed by the 30% §48E tax credit and 5-year MACRS depreciation.
Inland Empire Industrial & Commercial Economics
Riverside and San Bernardino counties combine the largest commercial rooftop footprints in Southern California with extreme summer cooling loads and high solar irradiance.
Inland Empire industrial owners, logistics operators, and cold-storage facilities capture the 30% federal §48E investment tax credit, 5-year MACRS depreciation, and potential 10% Domestic Content / Energy Community adders in qualifying Riverside and San Bernardino tracts.
High-bay HVAC, refrigeration, material-handling conveyors, and electric forklift/truck charging create expensive 15-minute kW spikes. We pair high-density rooftop arrays with commercial BESS to clip demand peaks and cover the 4–9 PM ramp.
Earn South Coast AQMD Rule 2305 WAIRE compliance points for warehouse solar and EV charging while keeping structural PE engineering, C-39 roof protection, C-10 switchgear, and Rule 21 interconnection under one in-house team.
OC Solar does not provide tax, legal, or accounting advice; consult your CPA or tax advisor regarding IRC §48E commercial tax credit, bonus adder, and MACRS depreciation eligibility. Savings and ROI figures are owner-provided projections that assume average utility rates escalating ~5% annually. Estimates only — individual results vary; not a guarantee.

Inland Empire Commercial Solar FAQ
While the residential homeowner credit (§25D) expired on December 31, 2025, commercial and industrial properties in Riverside and San Bernardino counties remain eligible for the 30% federal Clean Electricity Investment Credit (IRC §48E) in 2026 (when meeting prevailing-wage/apprenticeship rules or the under-1 MW AC exemption), plus potential 10% Domestic Content or Energy Community bonus adders in qualifying census tracts and 5-year MACRS accelerated depreciation.
Most of the Inland Empire (Ontario, Rancho Cucamonga, Fontana, Rialto, San Bernardino, Corona, Moreno Valley, Perris, Temecula, Murrieta, and Palm Springs) is served by Southern California Edison (SCE), where commercial accounts on TOU-GS-2, TOU-GS-3, and TOU-8 face steep 15-minute demand charges ($/kW) and 4–9 PM peak rates that make commercial battery energy storage (BESS) essential. In the City of Riverside, Riverside Public Utilities (RPU) operates independent municipal commercial tariffs, while in Indio, Coachella, and La Quinta, Imperial Irrigation District (IID) runs its own commercial Net Billing and demand tariffs where heavy desert HVAC and cold-storage loads benefit from solar + storage.
Yes. Warehouse operators and industrial landlords subject to South Coast AQMD Rule 2305 (Warehouse Actions and Investments to Reduce Emissions / WAIRE) earn compliance points by installing rooftop solar PV, battery storage, and zero-emission truck/yard-tractor charging infrastructure. Our in-house B General Building, C-10 Electrical, and C-39 Roofing teams engineer integrated solar + BESS + EV charging microgrids that satisfy WAIRE points while preventing fleet chargers from triggering massive SCE demand penalties.
Yes. OC Solar holds an active California C-39 Roofing license alongside our B General Building and C-10 Electrical licenses (CSLB #1023627). Before engineering any ballast, heat-welded TPO, or standing-seam attachment system on an Inland Empire warehouse or cold-storage facility, we evaluate structural dead-load capacity, panelized wood or steel deck framing, and remaining membrane life under one unified contract.
