Commercial rooftop solar installation engineered by OC Solar in Orange County

Commercial Solar & BESS · Irvine HQ · Orange County, CA

Commercial Solar & Battery Storage in Orange County

Headquartered in Irvine, OC Solar engineers and builds turnkey commercial solar, carport, and battery energy storage systems (BESS) across Orange County. Capture the 30% federal §48E tax credit and 5-year MACRS depreciation while slashing SCE, SDG&E, and Anaheim Public Utilities demand charges.

2026 Commercial Economics (§48E + MACRS)

Why 2026 is a landmark window for Orange County commercial solar + storage

While the residential homeowner tax credit (§25D) expired at the end of 2025, businesses and commercial property owners retain full access to the federal §48E investment tax credit and accelerated depreciation.

30% IRC §48E Tax Credit + 5-Year MACRS

Businesses, industrial facility owners, and commercial landlords in Orange County still qualify for the 30% federal §48E investment tax credit (plus potential 10% Domestic Content / Energy Community adders) and 5-year MACRS depreciation — often offsetting 50%–65%+ of gross capital cost.

SCE TOU-GS Demand-Charge Shaving + BESS

Under CPUC Net Billing, commercial solar alone leaves 15-minute demand spikes ($/kW) and 4–9 PM peak charges exposed. We pair high-density commercial arrays with intelligent BESS controls that cap peak kW draw and discharge stored solar through the evening ramp.

Irvine HQ · In-House B, C-10 & C-39

Dispatched directly from our Irvine headquarters (240 Progress, Suite #100), our own licensed crews handle structural PE stamping, C-39 roof attachments, C-10 switchgear/transformer upgrades, city plan check, and SCE/APU/SDG&E Rule 21 interconnection.

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.

Engineered around your 15-minute interval data and roof life

We don't guess from a single monthly bill. Our commercial engineering team pulls your 12-month Green Button 15-minute interval data from SCE, SDG&E, or Anaheim Public Utilities to model kW demand peaks, load factor, and post-solar tariff switches.

Orange County Commercial Solar FAQ

§48E tax credits, MACRS & SCE demand-charge questions answered

No. While the homeowner residential tax credit (IRC §25D) expired on December 31, 2025, the federal Clean Electricity Investment Credit for commercial and business properties (IRC §48E) remains active in 2026. Qualifying Orange County commercial solar and battery energy storage systems (BESS) can claim a 30% base federal tax credit (when meeting prevailing-wage/apprenticeship rules or the under-1 MW AC exemption), plus potential 10% Domestic Content or Energy Community bonus adders, alongside 5-year MACRS accelerated depreciation.

In Southern California Edison (SCE) territory across Orange County, commercial accounts on TOU-GS-2, TOU-GS-3, or TOU-8 pay both volumetric energy charges ($/kWh) and monthly facility and time-related demand charges ($/kW) based on their highest 15-minute load spike. Rooftop or carport solar offsets daytime kWh consumption, while a commercial Battery Energy Storage System (BESS) monitors facility load in real time to clip 15-minute demand spikes and shift stored solar into SCE's 4–9 PM peak window.

Headquartered in Irvine, our in-house B General Building, C-10 Electrical, and C-39 Roofing teams engineer and construct rooftop, carport, and BESS installations for industrial and flex buildings, medical and professional offices, retail centers, cold storage and food distribution, HOA common areas, multifamily properties (including Virtual Net Energy Metering / VNEM), and auto dealerships across Irvine, Anaheim, Santa Ana, Huntington Beach, Costa Mesa, Newport Beach, Tustin, Orange, Fullerton, and Lake Forest.

Yes. Most of Orange County is served by Southern California Edison (SCE Rule 21 interconnection), the City of Anaheim operates its own municipal utility (Anaheim Public Utilities / APU), and south-county cities including San Clemente, Dana Point, Laguna Niguel, Mission Viejo, and San Juan Capistrano fall fully or partially within SDG&E territory. Our in-house engineering team models your exact utility tariff and manages Rule 21 / municipal interconnection and city AHJ plan check end-to-end.

Yes. Because OC Solar holds an active California C-39 Roofing license alongside our B General Building and C-10 Electrical licenses (CSLB #1023627), we evaluate your existing TPO, PVC, built-up, or metal roof membrane before any racking is engineered — and can execute reroofing or structural attachment upgrades under one unified commercial contract.
