Fast, Reliable Commercial Solar Installation Across Selma
Commercial solar in Selma pays for itself faster than almost anywhere in California, but only if the system is sized for what actually happens here. Summer sun is generous. Winter tule fog is not. That’s the difference between a proposal that looks good on paper and one that holds up on your year-25 true-up statement. Gus Petrakis has been quoting real production numbers in the San Joaquin Valley since 2011, and we do the math off your actual PG&E bill, not a brochure. Call (877) 550-6892 and bring us a bill. We’ll bring you the numbers that hold.
Why Gus’s Solar Is Selma’s Preferred Commercial Solar Installation Company
We’re not a door-knock crew. Gus Petrakis puts his own name on the truck, publishes his license number, and answers his own phone. When a Selma business calls with a question after the system goes live, a live person picks up, 24/7. Not a voicemail. Not a ticket queue three states away.
That matters in a town like Selma, where word travels fast and a bad install gets remembered for years. Our crew has done rooftop work on warehouses off Floral Avenue, ground mounts on raisin sheds, and carport arrays at commercial lots throughout 93662. We know the local code officials, the PG&E interconnection process for this service territory, and the specific panel upgrade requirements that trip up out-of-town installers who have never dealt with a 1970s-era commercial panel in the valley.
Every job carries the 90-Day Done Right Promise, in writing. If it’s not right, one call brings Gus back. That’s how a business owner talks to another business owner.
Our Commercial Solar Installation Services in Selma
Commercial Rooftop Solar
Selma’s older commercial buildings, many built between the 1950s and 1980s, have low-pitched roofs with strong south-facing exposure. That’s good news for production. The catch is that most still carry original 100-amp electrical panels, which cannot pass interconnection for a grid-tied solar array. We handle the service upgrade as part of the job, so you’re not juggling a solar contractor and an electrician. Our Commercial Solar Installation team has spec’d rooftop systems on warehouses, retail buildings, and processing sheds throughout the city.
Warehouse & Industrial Solar
Warehouse solar in Selma is a different animal from residential work. These buildings run heavy loads: refrigeration, conveyors, processing equipment. A system sized on summer peak sun hours alone will leave you with disappointing winter true-ups, because tule fog suppresses daily irradiance to under 2 kWh/m² for stretches between Thanksgiving and February. We size warehouse arrays on annual averages, using 12 months of your actual interval data. The result is an offset number you can take to the bank, not a peak-day number that dissolves in December.
Solar Carport Installation
For Selma businesses with limited roof square footage or aging roof membranes, carport solar turns existing parking into generation. On 105°F+ summer afternoons, carport panels also shade employee and customer vehicles, which is a real benefit when the alternative is a 160°F dashboard at quitting time. Carport structures require engineered wind-loading calculations, and we handle that in-house.
Commercial Battery Storage
Commercial battery storage is gaining traction in Selma because PG&E’s time-of-use rates penalize the exact hours when the valley is hottest. A FranklinWH or Tesla Powerpack system lets you run off stored solar during peak-rate windows instead of buying grid power at the most expensive time of day. For cold storage and food processing facilities in 93662, where a brief outage can cost thousands, batteries also provide ride-through protection.
Agricultural & Ground-Mount Solar
Selma sits in the densest stretch of San Joaquin Valley raisin-grape territory. Ground-mount solar on agricultural properties works well here because there’s land, and the summer peak aligns with irrigation and cooling loads. We install ground mounts for pump stations, packing houses, and ranch operations. These systems need to be sized around annual output, not just the July spike, because the fog months drag down the yearly average. We quote the year-25 number, not the day-one brochure figure.

Trusted Brands We Service in Selma
We work with the equipment that holds up in Selma’s heat and fog: Enphase microinverters, SolarEdge inverters with module-level rapid shutdown, FranklinWH batteries, and Tesla storage. We keep common replacement parts stocked locally, which means when a Selma business has an inverter fault or a monitoring issue, we’re not waiting on a freight shipment from Ohio. Gus’s own crew handles every install, background-checked and uniformed, and they flash every roof penetration properly. No subs. No shortcuts.
Common Commercial Solar Installation Problems We See in Selma Homes
- Undersized systems built on summer peak numbers. An installer quotes July production and makes it look like solar will erase the bill. Then tule fog arrives and the winter true-up disappoints. We’ve been called out to fix more than one of these, and the fix is usually adding capacity or battery storage to bridge the fog season.
- Original 100-amp panels failing interconnection. Selma’s 1950s-1980s commercial buildings frequently still run on 100-amp service. The permit gets rejected, the project stalls, and the business owner is left wondering why nobody flagged it. We check panel capacity before we ever quote a number.
- Thermal derating not modeled. On Selma’s 105°F+ summer afternoons, panel surface temps can hit 160°F+, which triggers a 15-20% production penalty. A proposal that doesn’t account for this makes July look better than it will actually be. We surface this upfront, because being honest about derating is easier than apologizing for a high summer bill later.
- Mismatched inverters for partial-shade roofs. Older commercial roofs in Selma often have vents, HVAC units, and trees that cast moving shade. A string inverter system will suffer disproportionately. Enphase microinverters or SolarEdge optimizers handle partial shade far better, and we spec accordingly.

FAQs - Commercial Solar Installation in Selma
Tule fog cuts Selma’s solar irradiance by 50-70% for weeks at a stretch between November and February, dropping daily production below 2 kWh/m². A system sized on summer peak sun will dramatically underproduce in winter, so any honest Selma proposal must be built on annual averages, not July numbers. We model your system using 12 months of actual interval data from PG&E. If a proposal you’re holding only shows summer production, call (877) 550-6892 for a second opinion. Free second opinions on any written estimate are a standing offer.
On Selma’s hottest summer afternoons, panel surface temperatures reach 160°F or higher, which reduces panel output by 15-20% through thermal derating. A proposal that ignores this will overpromise July production, and you’ll see the shortfall on your bill. We factor derating into every Selma proposal so the production estimate matches what actually shows up on the meter.
Not without a service upgrade. Selma’s older commercial buildings, especially those built between the 1950s and 1980s, often run on 100-amp panels that PG&E will not interconnect for a grid-tied solar array. The upgrade to 200-amp service adds cost but it’s a one-time fix, and we handle it as part of the installation. Bring us a bill and we’ll tell you exactly what your building needs before you spend a dollar.
No. Selma is in PG&E territory, and net metering works the same as it does in Fresno, Kingsburg, and the rest of the PG&E service area. What’s different is the weather: Selma’s tule fog is denser and longer-lasting than what you’d see in the southern valley, so winter production modeling matters more here than it does for a warehouse in Fresno. We build that into every estimate.
For most Selma warehouses, rooftop solar wins on cost per watt if the roof is in good shape and has unobstructed southern exposure. A carport makes sense when the roof is aging, shaded, or structurally limited, or when you want the added benefit of shaded parking. We gave one warehouse owner off Floral Avenue a straight comparison: the rooftop array came in lower per watt, but the carport added 20 years of useful life without touching a 50-year-old roof membrane. Call (877) 550-6892 and we’ll run the same comparison for your building, free.
