AfterFast, Reliable Commercial Solar Installation Across Lodi
Commercial solar installation in Lodi typically runs $2.10-$2.85 per watt for rooftop systems and $1.65-$2.25 per watt for ground-mount projects, with most ag and winery jobs landing between $180,000 and $650,000 before incentives. We design, permit, and install three-phase systems for warehouses, wineries, cold-storage facilities, and commercial buildings across the 95240, 95241, and 95242 ZIP codes. If you’re weighing solar for a business or farm operation in Lodi, call Gus’s Solar at (877) 550-6892 and we’ll pull your actual PG&E interval data before we quote you a single number.
We’ve been doing Commercial Solar Installation long enough to know that Lodi is not like the rest of the Central Valley when it comes to energy loads. A winery pumping water and running glycol chillers on three-phase service has nothing in common with a retail shop in Stockton. Neither does a cold-storage warehouse pulling compressors around the clock. Sizing a system here means understanding harvest schedules, fog-driven production dips, and demand charges that spike in August. That’s the work we do every week in Lodi.
Why Gus’s Solar Is Lodi’s Preferred Commercial Solar Installation Company
Commercial solar in Lodi is mostly repeat business and referral business. The growers talk to each other. The winemakers see each other at Lodi Rules meetings and crush-season dinners. If you mis-wire a three-phase pump or undersize a rooftop array on a warehouse, the whole grape-growing community knows within a month. That’s the kind of accountability a pop-up solar sales crew can’t survive, and it’s exactly why Gus Petrakis puts his own name on the work.
Gus founded this company in 2011 and has been answering his own phone ever since. Not a call center. Not a sales floor. When you call about a commercial array in Lodi, a live person picks up, 24 hours a day, seven days a week. If something stops working at 2 a.m. during crush season, you will talk to a human being who knows what a compressor load looks like on a PG&E bill.
Every commercial job we do carries the 90-Day Done Right Promise in writing. If the system doesn’t produce what we modeled, Gus comes back and makes it right. That’s not a slogan. It’s on every contract.
Our crews serve Lodi directly from the Fresno-area office. Background-checked, uniformed, and trained on three-phase commercial work, not just residential rooftop installs. No subcontractors. The same team that designs your array is the team that bolts it down.
Our Commercial Solar Installation Services in Lodi
We cover the full spread of commercial work in Lodi, from a 30 kW rooftop on a warehouse off Turner Road to a half-megawatt ground-mount for a vineyard pumping station. Here’s what most Lodi owners call us for:
Commercial Rooftop Solar
Flat and low-slope commercial roofs are the most common install type in Lodi’s industrial corridors and downtown core. We handle membrane roofs, TPO, and metal deck roofing with penetration flashing done by our own crew, not handed off to a roofer we’ve never met. For older buildings near Downtown Lodi and the area west of Highway 99, we check the structural load rating before anything gets bolted down. A 1960s warehouse with a wood truss roof often can’t handle a full ballasted array without reinforcement, and we’d rather tell you that in week one than discover it at permit inspection.
Warehouse & Industrial Solar
Warehouses near the Lodi Industrial Park and the older facilities along Cherokee Lane tend to have flat roofs and large open interiors, which makes them good candidates for high-coverage arrays. The catch is that many of these buildings run big HVAC and lighting loads on older three-phase panels. We model the actual operating hours, not just the square footage, so the array gets sized to your real draw. A 75,000-square-foot warehouse in Lodi running one shift with moderate refrigeration often needs a 250-400 kW system to meaningfully offset PG&E charges.
Solar Carport Installation
Carport solar makes sense for Lodi businesses with open parking lots and high afternoon electricity loads. Wineries with tasting rooms, distribution centers, and office buildings along Kettleman Lane are all candidates. Carports run higher per watt than rooftop, typically $2.50-$3.10 per watt in Lodi, because they require steel substructure and deeper footings. West-facing carport canopies also capture late-afternoon sun that matches PG&E’s peak TOU pricing window, which shortens the payback on those projects.
Commercial Battery Storage
Battery storage is where Lodi’s commercial math gets interesting. PG&E’s demand charges in this area are steep, especially for three-phase accounts with big motors. A Tesla or FranklinWH battery paired with a properly programmed inverter can shift load off-peak and shave demand spikes. For a winery running chillers during crush, we routinely design systems that move 70-80% of the peak load off the grid. The battery isn’t an accessory in Lodi. For many accounts, it’s the part that makes the whole project pencil out.
Agricultural & Ground-Mount Solar
Vineyard and orchard accounts around Lodi frequently have land available for ground-mount arrays, and those projects are typically the cheapest per watt because there’s no roof complication. We size these to the specific pump, irrigation, and cold-storage loads on the property. A 100-acre vineyard east of Lodi running drip irrigation and a small cold-storage shed might only need 75-120 kW. A winery with a tasting room, barrel storage, and a crush pad may need 400 kW or more. We model it off your utility data, not a generic farm estimate.

Trusted Brands We Service in Lodi
We work with the equipment that holds up in the San Joaquin Valley. Panasonic and Canadian Solar modules are our go-to for commercial rooftops in Lodi because they handle high heat without the degradation rates you see in cheaper panels. JinkoSolar makes sense for large ground-mount arrays where cost per watt drives the decision. For battery storage, we install FranklinWH for commercial accounts because the power electronics handle motor-start loads without needing a second inverter. We don’t push one brand. We match the hardware to your actual load and the fog-and-heat conditions specific to Lodi.
Common Commercial Solar Problems We See in Lodi
- Tule fog slashes winter production far more than the brochures admit. From Thanksgiving through February, dense ground fog reduces effective sun hours by 30-40% compared to summer. A system sized on annual average output without battery reserve will leave you buying peak-priced grid power during the worst stretch.
- Older commercial buildings fail PG&E interconnection checks. Buildings from the 1950s through the 1970s in Lodi’s core often have 200-amp or smaller three-phase panels and conduits that won’t pass current codes. Expect two to four extra weeks on the permit timeline if your service needs an upgrade.
- Undersized conductors and missing rapid shutdown compliance. This is what we see most when we’re called to fix a competitor’s install. Flat warehouse roofs in Lodi get treated like residential ground mounts by crews that don’t know commercial code. The fix is usually a full conductor replacement and a re-permit.
- Three-phase pump and chiller loads mis-wired or under-sized. A residential crew can’t properly design a system for a winery’s irrigation pumps and glycol chillers. We correct these installs more often than we’d like to talk about, and the repair usually costs more than the original install saved.
Pricing for Commercial Solar Installation in Lodi, CA
Here’s what commercial solar actually costs in Lodi, based on the jobs we bid and install:
- Commercial rooftop solar: $2.10-$2.85 per watt. A 100 kW system runs roughly $210,000-$285,000 before incentives.
- Ground-mount solar: $1.65-$2.25 per watt. A 200 kW vineyard array lands between $330,000 and $450,000.
- Solar carports: $2.50-$3.10 per watt. Smaller than rooftop but structurally intensive.
- Commercial battery storage: $650-$900 per kWh installed. A 100 kWh FranklinWH or Tesla system runs $65,000-$90,000.
- Service upgrade (200-amp to 400-amp or higher): $6,000-$18,000 depending on conduit, panel, and utility coordination.
These figures are for the Lodi market as of 2026. They move with equipment pricing and PG&E tariffs, so don’t treat them as static. What they give you is a baseline.

FAQs - Commercial Solar Installation in Lodi
Lodi’s fog cuts winter production by 30-40% below summer levels, so a system sized on annual average output will run short every winter unless we add battery storage or over-size the array by 20-30%. That’s the fog math we build into every commercial model here. Call us at (877) 550-6892 for a production forecast that accounts for it.
Wineries run irrigation pumps, crush equipment, and glycol chillers on three-phase power, and a system designed for single-phase loads won’t handle the motor-start surge. We size the inverter and conductors to the actual three-phase load profile. If a salesman can’t read your three-phase panel schedule, don’t let him quote your array.
Yes, but it requires an over-sized array, battery reserve, or both. The typical approach is to design for 110-120% of annual usage with battery storage to carry you through fog stretches. That’s a conversation about your actual PG&E data, not a brochure number. We’re happy to run it for free.
It can. Lodi Rules rewards renewable energy adoption with market access and pricing benefits, and some equipment choices like battery storage help meet the program’s energy-efficiency thresholds. We’ve worked with multiple Lodi Rules growers and can walk you through what counts toward certification. Call (877) 550-6892 and tell us you’re in the program.
A service upgrade on an older Lodi commercial building typically adds $6,000-$18,000 and two to four weeks to the timeline. Three-phase inverter and conductor work adds $8,000-$25,000 depending on system size. These are common on 1950s-1970s buildings in Lodi’s core. We’ll tell you upfront if you need it, before you sign anything.
