Fast, Reliable Commercial Solar Installation Across Los Angeles

Getting commercial solar installed in Los Angeles means dealing with two approval tracks at once: LADBS building permits and LADWP interconnection review. That dual workflow trips up out-of-town installers every single week. We know it cold. A typical commercial rooftop array in Los Angeles runs $85,000 to $240,000 before incentives, depending on system size and roof conditions, and most projects take 4 to 9 months from signed agreement to permission to operate.

Why Gus’s Solar Is Los Angeles’s Preferred Commercial Solar Installation Company

Gus Petrakis founded this company in 2011, and his name is on every truck, every quote, and every job we finish in Los Angeles. He publishes his address and license number. He answers his own phone. When a commercial client in Koreatown calls about a monitoring alert, Gus is the one who picks up, not a call center in another state. That’s the difference between a local owner-operator and the national outfits that vanish after the paperwork clears.

We’ve worked commercial rooftops across 90015, 90016, 90017, and 90018 for years. Flat roofs on 1960s warehouse buildings in South LA. Sloped metal roofs on 1970s auto shops near Echo Park. Tight setbacks and alley-load clearances everywhere. Our crew knows which LADBS inspectors want what, which LADWP application screens cause the most delays, and how to sequence the permit and interconnection filings so the project doesn’t stall mid-stream.

We also hold the line on no-pressure. Bring us a bill, we’ll bring you the math. Take two weeks. Think about it. The price will be the same. If a salesman needs an answer tonight, the answer is no. That’s how Gus runs every commercial solar job in Los Angeles, and it’s why property owners keep calling us back for maintenance and battery add-ons years later.

Our Commercial Solar Installation Services in Los Angeles

Commercial Rooftop Solar

Flat commercial roofs dominate the warehouse and retail stock across Los Angeles, and they’re our bread and butter. We do ballasted and mechanically attached arrays on EPDM, TPO, and modified bitumen roofs, and we flash every penetration properly. Panels from Qcells, REC, or SunPower paired with Enphase microinverters are standard on our commercial jobs. In the South LA flatlands east of the coastal marine layer, these systems routinely out-produce similar arrays on the Westside by a measurable margin, which matters when you’re sizing against LADWP’s tiered commercial rate schedules.

Warehouse & Industrial Solar

Large industrial buildings in ZIPs like 90015 and 90017 often have the roof square footage to offset 60 to 80 percent of annual load with a correctly sized array. We start every industrial estimate with a structural review, because many 1960s and 1970s buildings were never engineered for added roof load. Gus’s crew handles the full permit package, including the LADBS structural sign-off and the LADWP interconnection application, so you’re not juggling two agencies yourself.

Warehouse & Industrial Solar

Solar Carport Installation

Carports make sense for commercial lots across Los Angeles where usable roof space is limited or shaded. A commercial carport array in the $120,000 to $300,000 range typically pays for itself through LADWP’s commercial net metering credits over 6 to 9 years. We handle the full design, engineering, and dual-permit workflow. Property owners near Silver Lake and Echo Park often pair carport solar with EV charging stations, and we install both.

Commercial Battery Storage

Commercial battery storage in Los Angeles is becoming a no-brainer for businesses that lose revenue during rolling outages. We install FranklinWH and Enphase battery systems sized to your actual load profile, not a generic template. In LADWP territory, where time-of-use windows and demand charges can eat into solar savings, a correctly sized battery shifts discharge into peak windows and cuts demand charges. We quote year-25 output, not the day-one brochure number, so you know what the storage system will actually do for you a decade from now.

Trusted Brands We Service in Los Angeles

We work with the equipment brands that hold up under Los Angeles sun, heat, and smog residue. Qcells and REC modules are our go-to for most commercial rooftops; we also install SunPower and Panasonic where the project calls for premium efficiency. All of our commercial battery work uses Enphase or FranklinWH. We stock replacement microinverters, optimizers, and monitoring components locally, so a service call in 90016 doesn’t wait on a shipment from a distribution center in Nevada. When a monitoring alert flags an underperforming panel on a warehouse in 90018, we can usually be on the roof within 48 hours.

Common Commercial Solar Installation Problems We See in Los Angeles

  • Panel upgrades on 1920s-1950s buildings: Most commercial buildings in this stock still run on original 100-amp or sub-100-amp services. A new solar array plus rapid shutdown and inverter load will fail inspection unless the panel is upgraded first. We assess this on day one and price the upgrade into the quote, not as a surprise change order.
  • LADWP interconnection queue delays: LADWP’s interconnection process has historically taken two to four times longer than SCE’s. Teams that assume SCE-style 4-6 week approvals blow project timelines and trigger client escalation. We file the LADWP application the same week the LADBS permit is submitted, and we track both approvals in parallel.
  • Oil field encumbrances in 90008: The Baldwin Hills-Inglewood Oil Field sits directly beneath parts of this ZIP. Surface-rights encumbrances or subsurface easements held by Legacy Oil can surface during title review and stall LADBS permit issuance. We pull a full preliminary title report before scheduling any site assessment in this area.
  • Dense apartment-building complexity in Koreatown: The 1960s-1970s 2-to-8-unit apartment buildings that blanket Koreatown come with shared roofs, multiple meters, and tenant-occupied units. That means the design has to account for virtual net metering or common-area load allocation, and the permitting gets layered. We’ve done enough of these to know what LADWP will accept without months of back-and-forth.

Pricing for Commercial Solar Installation in Los Angeles, CA

Commercial rooftop solar in Los Angeles typically runs $2.20 to $2.80 per watt installed, meaning a 50 kW system lands between $110,000 and $140,000 before the federal tax credit and LADWP incentives. Solar carports run higher, usually $3.00 to $4.00 per watt because of the steel structure. Commercial battery storage adds $700 to $1,100 per kWh of capacity, depending on the battery chemistry and sizing. What actually moves the number on a Los Angeles commercial job: panel upgrade requirements, roof condition and remaining life, structural reinforcement on older warehouses, and whether the building is in LADWP’s fast-track interconnection zone or the slow queue. We quote off your actual utility bill and your actual load profile, not a brochure estimate. Call (877) 550-6892 and we’ll walk the property and give you a number you can hold us to.

What San Jose Customers Say

Trusted by homeowners across San Jose and surrounding areas.

★★★★★

"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."

Octavius Redmond · Verified customer
★★★★★

"Production dropped one spring and I did not even notice. Gus rang me, because he watches the monitoring, and had it sorted the same week."

Sunita Balakrishnan · Verified customer
★★★★★

"My previous solar company went out of business and left me with an array nobody would touch. Gus took the system over, replaced two dead microinverters, and it has run properly since."
