Fast, Reliable Commercial Solar Installation Across Temple City

Commercial solar in Temple City means running real math on Southern California Edison’s NEM 3.0 rates, your building’s actual electrical panel, and the tile roof under the panels. Our Commercial Solar Installation team does that before we ever quote a wattage. We’re Gus’s Solar, and we’ve been doing this long enough to know that a 1950s bungalow off Las Tunas Drive hides different problems than a 1990s warehouse on Baldwin Avenue. If you’re weighing numbers or just want someone to look at the roof, call (877) 550-6892 and Gus Petrakis will pick up.

Why Gus’s Solar Is Temple City’s Preferred Commercial Solar Installation Company

We’re not a door-knocking outfit. Gus Petrakis put his name on the building, answers his own phone, and still tells commercial owners to take two weeks before signing anything. That matters in Temple City, where plenty of business owners got burned by an out-of-state installer that quoted one number over the phone and another at the permit counter. We’ve built our reputation in Temple City on doing the opposite: the price we quote is the price you pay, in writing, backed by our 90-Day Done Right Promise.

Our crews come to Temple City regularly. We know the building department’s permitting quirks, the tile roofs along Las Tunas and Live Oak, and the hidden electrical panels that stall so many rooftop solar projects in 91780. When you call, a live person answers, not a voicemail tree. Gus himself checks the system after install. If something’s not right, one call brings him back.

Our Commercial Solar Installation Services in Temple City

Commercial Rooftop Solar

Rooftop arrays on Temple City’s older commercial stock, from converted ranch houses to strip-mall storefronts, need more than a generic racking kit. Most of these roofs wear concrete tile or clay tile laid on 1940s to 1970s framing. We spec mounting hardware built for that tile profile and flashing that keeps rain out of the valleys around the air conditioner curbs. A typical Temple City commercial rooftop array runs $2.45 to $3.20 per watt installed, with most smaller commercial roofs landing between 15 and 40 kilowatts.

Warehouse & Industrial Solar

Warehouses along Baldwin Avenue and the industrial pockets near the Rosemead border usually have flat or low-slope roofs that can hold serious panel capacity. These buildings burn through kilowatts with HVAC, refrigeration, or lighting, and that’s where a properly sized array pays off fastest. We design for actual year-25 output, not the day-one brochure number. If your warehouse has a 200-amp service already, a 100-kilowatt rooftop system can offset the bulk of your daytime load under SCE’s commercial rate schedules.

Solar Carport Installation

Carports solve two Temple City problems at once: parking shade for employees or customers, and panel area when the existing rooftop can’t support more weight, plus they pair naturally with Temple City EV Charger Installation. Given how many Temple City commercial lots are fully paved with no tree cover, a carport array can often hold 40 to 60 panels while keeping cars cooler through the San Gabriel Valley summers. We engineer the footings for local seismic requirements and size the inverter for your actual load profile.

Commercial Battery Storage

In Temple City, Solar Battery Storage & Backup in Temple City isn’t an extra. It’s the difference between a solar array that saves money and one that makes almost none. Because Temple City sits entirely inside Southern California Edison territory under NEM 3.0, pushing excess solar to the grid earns you pennies. Storing that generation in a FranklinWH or Enphase battery and drawing on it during peak afternoon and evening hours is where the financial return actually happens. We design commercial storage systems to shave demand charges, not just to arbitrage export rates.

Trusted Brands We Service in Temple City

We install and maintain systems built around the equipment we trust to hold up in the LA Basin’s heat and smog. On Temple City commercial jobs, we most often spec Enphase microinverters, REC or SolarEdge panels rated for low light-angle and high-temperature performance, and FranklinWH battery storage for NEM 3.0 economics. Because our trucks are on Temple City roads every week, we can get replacement parts and service calls done quickly, without waiting on a warehouse three states away.

Common Commercial Solar Installation Problems We See in Temple City Buildings

  • Original 60- or 100-amp panels hiding behind a remodeled interior. We’ve scoped 1950s and 1960s commercial buildings in Temple City with flawlessly renovated storefronts and kitchens, only to find a Zinsco or Federal Pacific panel in the back room. The solar permit stalls until that panel is swapped for a modern 200-amp service, and the upgrade needs to be in the quote from day one.
  • Tile and concrete roofing that generic racking can’t handle. A big percentage of Temple City’s commercial buildings sit on concrete tile roofs. Coastal-market installers often underprice the job because they assume composite shingle mounting. The labor and hardware for tile replacement and specialized hooks adds real cost, and if the bid doesn’t include it, you’ll get a change order mid-project.
  • Smog and particulate soiling that quietly kills production. Temple City sits in the LA Basin inversion layer, where photochemical smog and fine dust settle on panels and cut output measurably. Owners who skip a maintenance plan on a commercial array here lose more production than they would in a coastal city. We offer a Commercial Solar Installation maintenance program built around that reality, and our techs can clean and inspect your array on a schedule that accounts for local soiling patterns.
  • Designs that ignore NEM 3.0 and skip storage. A solar-only design in Temple City under SCE’s current export rates can turn a promising payback calculation into a multi-year financial loss. If nobody in the sales process asks to see your last twelve months of SCE bills and your actual load data, walk away. We won’t quote you a system without that conversation.

Pricing for Commercial Solar Installation in Temple City, CA

A small commercial rooftop array in Temple City (15 to 25 kW) typically runs $55,000 to $90,000 before any tax credit or depreciation. A mid-size warehouse or carport system (50 to 100 kW) lands between $130,000 and $300,000, depending on roof condition, panel upgrades, and storage. A battery system sized for demand-shaving on a typical Temple City retail or small warehouse building adds $45,000 to $120,000 depending on capacity and brand. The panel upgrade that so many older Temple City buildings require runs $6,000 to $15,000, and it’s usually the first thing we scope. Every bid comes from your actual SCE bill, not a brochure. We’ll give you the math in writing and tell you to take two weeks. Bring us a bill, we’ll bring you the numbers. Call (877) 550-6892 for a free estimate. We never ask for a decision on the spot. If a salesman needs an answer tonight, the answer is no.

What Temple City Customers Say

Trusted by homeowners across Temple City and surrounding areas.

★★★★★

"Panel level monitoring so I can see each one, proper stainless clips under the array rather than zip ties, and he walked me under it with a torch to show me before he signed off."

Cassius Delacroix · Verified customer
★★★★★

"Gus's own crew did the install. Not a subcontractor who had never met him, which is what the big outfit quoted me and could not tell me who would actually be on my roof."

Aurelia Santibanez · Verified customer
★★★★★

"He modelled it on my actual bill and the current export rates rather than the old ones, and told me plainly that the payback was longer than the door knockers had claimed. Then it came in about where he said it would."
