Car Dealerships Going Solar in California: Canopies, EV Charging and the Numbers to Check

California car dealerships that go solar usually use two surfaces: the showroom and service-building roofs, and parking canopies over the inventory or customer lot. Whether it pays comes down to three things: the demand charges on the dealership's business tariff, how EV charging is metered and timed, and whether a new system can be placed in service before the federal credit deadline that applies to it.

This guide is part of the commercial solar hub for California businesses. Dealerships are retail sites, and the retail solar guide covers the landlord and lease questions that also apply here. Sources were checked September 23, 2026.

Why dealerships look at solar

A dealership combines a large daytime load (showroom lighting and cooling, service bays with compressors and lifts, offices) with a lot of paved, unshaded space. That makes it a natural fit for on-site solar, and retail is one of the biggest commercial segments already doing it: Berkeley Lab's 2026 data update names retail, warehouse, industrial and office buildings as the largest business types among 2025 commercial installs, and found third-party ownership slightly more common at retail sites than at other commercial sub-segments.

EV charging adds a second reason. Chargers for inventory, demo and service vehicles raise the site's energy use and can set new demand peaks. Solar, storage and charging are best priced as one design, with each piece on its own line.

Roof or canopy: where the array goes

Roofs are usually the lower-cost host if they have years of life left and the structure can take the load. Showrooms with large glass areas and architectural roofs may have less usable space than the service building. See the commercial solar roofing guide for the roof checks.

Parking canopies cover inventory from sun and weather and give the array room to grow, but you pay for steel, foundations and site work. Canopy clearance has to suit vans and trucks on the lot, accessible spaces and any fire lane, and bidders should design for how cars are moved and displayed. The commercial carport cost guide explains what a canopy adds and how to read a bid.

What dealership carports cost. No public agency publishes a dealership or carport price. The nearest benchmark is Berkeley Lab's Tracking the Sun 2024 summary: large California commercial systems installed in 2023 had a median price of $2.3 per watt before incentives, across all mounting types. A canopy sits on top of that as steel, foundations, trenching and paving repair. Ask each bidder for the solar priced per watt and the structure priced per covered parking space, so you can compare canopy designs and hold the solar part against a roof quote.

The bill: demand charges and EV charging rates

Most dealerships are on a business time-of-use tariff with demand charges. SCE's business TOU page describes two kinds: a facilities-related charge set by the highest demand in the month at any hour, and a time-related charge set by the highest demand during on-peak or mid-peak weekday hours. Solar lowers energy purchases, but a cloudy interval or an evening charging session can still set the monthly peak. A commercial battery is the tool for that line.

Separately metered EV charging can move to an EV rate. PG&E's Schedule BEV is optional for commercial charging metered apart from the rest of the site. It replaces the customer charge and demand charge with a monthly subscription in kW blocks, and in rates effective March 1, 2026 it prices energy like this:

The super off-peak window overlaps midday solar production. Scheduling inventory and service-vehicle charging between 9 a.m. and 2 p.m. uses the array's output on site, while the 4 to 9 p.m. peak is the time to avoid. SCE and SDG&E customers should ask their utility for the equivalent EV rate before modeling.

Export credits favor using solar on site

Since April 15, 2023, new solar customers of PG&E, SCE and SDG&E take service on the CPUC's net billing tariff, which credits exports at values from the CPUC's Avoided Cost Calculator that are usually lower than the retail rate. For a dealership, that argues for sizing the system to daytime load, including scheduled EV charging, rather than filling every canopy for export. The commercial cost and bill guide shows how export credits enter the payback math.

New showrooms and remodels: code requirements

For new construction, the California Energy Commission's 2025 nonresidential solar PV guidance says Section 140.10(a) requires solar on newly constructed buildings of listed types, including retail, office and warehouse, generally with battery storage unless an exception applies. The Title 24 commercial solar requirements page covers sizing and exceptions.

EV charging has its own code track. CALGreen, Title 24 Part 11, sets green building standards for nonresidential new buildings, additions and alterations, its 2025 edition took effect January 1, 2026, and it includes EV charging provisions, according to the Building Standards Commission. Ask your city whether a lot reconfiguration or building addition triggers them before you lay out canopies and chargers.

Tax credits and depreciation in 2026

A dealership that owns its system can claim the credit under 26 U.S.C. §48E: 6% of the qualified investment, or 30% for a facility under 1 MW AC or one meeting the prevailing-wage and apprenticeship rules. For a solar facility whose construction began after July 4, 2026, there is no credit for property placed in service after December 31, 2027; storage at the facility is excepted from that cutoff. The statute excludes “a building or its structural components” from qualified property, so ask a tax professional how canopy steel is treated.

On depreciation, 26 U.S.C. §168(e)(3)(B)(viii) treats §48E qualified property and energy storage as 5-year property, and §168(k) allows 100% first-year depreciation for qualified property acquired after January 19, 2025. California does not conform to §168(k), per the FTB's 2025 Form 100 booklet. The charger credit in §30C does not apply to property placed in service after June 30, 2026. Have your tax professional confirm how these apply to your entity before a bid's after-tax numbers go into a decision.

If the dealership would rather not own the equipment, a lease or PPA moves the credit and depreciation to a third-party owner. Compare the options in PPA versus purchase and commercial solar financing options.

What to put in a dealership solar bid request

1. Twelve months of interval data for every meter, including any separately metered chargers.
2. The site plan with inventory, customer, service and accessible parking marked, plus fire lanes.
3. Planned charger count and power, and when vehicles can charge.
4. Roof age and condition for the showroom and service buildings.
5. The ownership structure you want priced, and whether you own or lease the land.
6. A request for canopy, solar, electrical, charger and battery lines priced separately.

Then compare bidders with the commercial solar company checklist.

When solar is the wrong move for a dealership

Wait if the site is due for a rebuild or major remodel, if the lot layout will change, or if you lease the land on a term shorter than the system's financing or contract. A dealership served by a publicly owned utility such as LADWP or SMUD should model that utility's own rates and export terms, since the CPUC net billing tariff applies to PG&E, SCE and SDG&E. And if a new system cannot realistically be placed in service before the credit deadline that applies to it, rerun the numbers without the credit before signing.
