Commercial Solar Installation in Los Angeles - Same-Day Service, Done Right the First Time

Fast, Reliable Commercial Solar Installation Across Los Angeles

Commercial solar installation in Los Angeles typically runs $2.40-$3.20 per watt for rooftop and carport systems, with most warehouse and retail projects landing between $45,000 and $220,000 before incentives. That’s the honest range, and it’s the number Gus Petrakis works from when he quotes your building, not a brochure. If you own commercial property in Los Angeles, you already know the city’s permitting path is different from everywhere else in the county. We’ve been navigating LADWP and LADBS since 2011, and we don’t hand your project to a sub. Call (877) 550-6892 and Gus will walk you through it.

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

Most Los Angeles commercial owners don’t need another sales pitch. They need a company that answers the phone and knows which permit desk to call. Gus Petrakis started Gus’s Solar in 2011 and never went anywhere. His name, his license number, and his phone number are all public. When a system underperforms, Gus is the one who calls you, not a rotating account manager.

We’ve installed and serviced commercial systems across South LA, Koreatown, Baldwin Hills, and downtown Los Angeles. Our customers keep our number saved because they know a live person answers at 2 a.m. when a monitoring alert fires. Not a voicemail. Not a “ticket.” Gus’s crew handles the work, background-checked and in uniform, and the 90-Day Done Right Promise sits in writing on every job. If it isn’t right, Gus makes it right.

Los Angeles response times matter because a down inverter on a 30-kW array is money leaving your building every hour. We send a crew same day when you’re in our coverage area. For commercial owners in 90015, 90016, 90017, and 90018, we’re typically on site within a few hours of your call.

Our Commercial Solar Installation Services in Los Angeles

Commercial Rooftop Solar

Flat and low-slope roofs dominate Los Angeles commercial buildings, from 1920s brick retail in South LA to tilt-up warehouses east of downtown. We engineer ballasted and attached systems that match your roof’s structural capacity, then flash every penetration properly. In Los Angeles, roof age matters as much as roof type. A 40-year-old roof under a 25-year solar lease is a problem waiting to happen, and we’ll tell you before you sign anything.

Commercial Battery Storage

LADWP’s time-of-use rates make commercial battery storage in Los Angeles a different math problem than SCE territory. Pairing a FranklinWH or Enphase battery with your array lets you shift midday generation into the 4-9 p.m. window, when LADWP’s commercial rates spike. For buildings with critical loads like cold storage or server rooms, we size the battery for backup duration, not just bill offset.

Solar Carport Installation

Parking lots in Los Angeles are expensive real estate, and a solar carport turns them into generation assets. We design steel carports for LA’s seismic requirements, something an installer from Arizona doesn’t think about until the plan reviewer asks. Carports also make sense when your rooftop is too small or shaded, which happens often on the dense commercial corridors through Koreatown and Echo Park.

Warehouse & Industrial Solar

Big roof, big bill, big opportunity. Warehouse and industrial solar in Los Angeles works best when we size it against your actual LADWP interval data, not a square-footage rule of thumb. We pull 12 months of usage before we design anything. That’s the difference between a system that offsets 60% of your bill and one that offsets 92%.

Trusted Brands We Service in Los Angeles

We work with equipment that performs in Los Angeles’s inland heat and occasional marine-layer mornings. That means Qcells and REC panels for most commercial rooftops, SunPower when the roof space is tight and you need maximum density, and Panasonic for owners who want a name they already trust on their building. We stock common replacement parts locally so a failed microinverter or string inverter in Los Angeles doesn’t leave you waiting a week for a part out of state. The brands we service are the brands we install, and we know their failure patterns well enough to fix them the first visit.

Common Commercial Solar Installation Problems We See in Los Angeles

• Mis-timed LADWP interconnection. A contractor files permits with LADBS but waits too long to start the LADWP queue. The system sits finished and dark for three months while the owner pays full commercial rates. We run both approvals in parallel, and we tell you the realistic timeline before the first panel goes up.
• Skipped preliminary title reports in Baldwin Hills. The 90008 ZIP sits over the Baldwin Hills-Inglewood Oil Field, one of the largest urban oil fields in the US. Some parcels carry subsurface easements held by Legacy Oil that surface only during title review. Installers who don’t pull a preliminary title report before the site assessment get blindsided at permit time.
• Undersized panels on aging 1920s electrical service. Commercial buildings from the 1920s and 1930s in South LA often still run 100-amp or even 60-amp service. A solar installer who connects a 28-kW array to that panel triggers shutdown faults the moment production ramps. Most of these buildings need a service upgrade before PTO, and we include that in the quote so it isn’t a surprise line item.
• Wrong production expectations for the wrong side of town. Inland commercial buildings in South LA and Koreatown generate more annual kWh than comparable rooftops in Santa Monica or Venice. The marine layer that suppresses June-to-August morning production on the Westside barely reaches east of the 110. We size your system for South LA’s actual sun profile, not a generic Los Angeles number.

In Los Angeles, LADWP requires both city and utility approval before commercial solar interconnection, a dual-permit process that nearly doubles project timelines compared to neighboring SCE territory like Culver City or Torrance. That’s the single biggest scheduling variable in this city, and most installers don’t flag it until your system is already mid-build. We do. On a 1930s stucco commercial building in South LA, we replaced a legacy 100-amp service panel before installing a 28-kW rooftop array. We coordinated LADBS and LADWP approvals in parallel, keeping the tenant’s operations running without interruption. That’s how commercial solar in Los Angeles gets done when the installer knows the city’s actual workflow.
