Fast, Reliable Commercial Solar Installation Across Burlingame
Commercial solar installation in Burlingame runs $2.40 to $3.60 per watt for most rooftop systems, meaning a 50kW array typically lands between $120,000 and $180,000 before incentives. We can usually start a commercial site survey within 5 to 7 business days of your call. Gus Petrakis has been putting his own name on commercial work since 2011, and he’s the one who answers when you call (877) 550-6892.
If you own or manage a warehouse, office building, or retail property in Burlingame, you already know the tree ordinance changes things. Mature oaks, redwoods, and deodar cedars shade rooftops here in ways they don’t in Millbrae or San Bruno. That’s not a sales objection. It’s a design constraint we’ve worked around for years, and we’ll show you exactly how on your first site visit.
Why Gus’s Solar Is Burlingame’s Preferred Commercial Solar Installation Company
We’re a local shop, not a pop-up sales crew. Gus founded the company in 2011 and he publishes his name, his license number, and his address. When you call about Commercial Solar Installation, you’re talking to the owner or to someone who can walk down the hall and get him. That matters in Burlingame, where property owners have been burned by out-of-state outfits that quote one number on the phone and a different one at the contract table.
Our reputation in Burlingame is built on a simple rule: bring us a bill, we’ll bring you the math. We pull your actual 12-month usage from PG&E or Peninsula Clean Energy, model your roof in satellite and on-site, and show you year-25 output numbers, not day-one brochure figures. If a salesman needs an answer tonight, the answer is no. We tell every commercial client the same thing: take two weeks. Think about it. The price will be the same.
Response time to Burlingame commercial sites is typically same-week for emergency issues and 5 to 7 business days for new project site surveys. Our L.O.C.A.L. values guide every job: Local roots, On time, Community first, Accountable, Loyal. Gus’s own crew does the install. No subcontractors. No dispatch queue. You call, a live person answers, and Gus knows your roof by name before the permits are filed.
Our Commercial Solar Installation Services in Burlingame
Commercial Rooftop Solar
Flat commercial roofs in Burlingame are everywhere, from the auto row off California Drive to the office parks near Highway 101. We design ballasted and mechanically attached systems that account for ponding water and the salt-laden air coming off the bay. Most systems we install in the 94010 and 94011 zip codes use a combination of Enphase microinverters and stainless or anodized aluminum racking. The microinverters aren’t an upsell here. They’re the correct engineering response to the protected tree canopy that shades so many Burlingame rooftops.

Warehouse & Industrial Solar
Warehouse roofs in Burlingame’s industrial corridors east of 101 see persistent morning marine layer from late May through August. A production model calibrated to Redwood City will overstate your annual yield by 8 to 12 percent. We model with Burlingame-specific irradiance data, not generic Peninsula averages. That’s the difference between a financial model you can take to the bank and one you’ll regret by year three.

Solar Carport Installation
Carports solve a real Burlingame problem: ground-level parking lots are often the only unshaded space on a property where protected oaks and redwoods ring the perimeter. We design steel carport structures that double as covered parking and solar production, which works well for office campuses and medical buildings along El Camino Real. The steel gets a marine-grade coating. Standard galvanized steel corrodes visibly within five years this close to the bay.

Commercial Battery Storage
Battery storage pairs with your array to shave demand charges and keep critical loads running during PG&E outages. We work with FranklinWH and Tesla commercial batteries, sized to your actual load profile. For Burlingame businesses, we also factor in the marine layer pattern: your battery charges later in the day than an inland site would, so we size accordingly.

Trusted Brands We Service in Burlingame
We install and service equipment from Tesla, Enphase, SolarEdge, and FranklinWH. We keep common commercial parts in local inventory, so a failed microinverter or a corroded disconnect on a Burlingame rooftop doesn’t wait a week for a shipment from Texas. Our team is trained on all four platforms, and we don’t lock you into one brand’s ecosystem. If your existing system uses SolarEdge and you want to expand with Enphase, we’ll make it work and stand behind the integration.
Common Commercial Solar Installation Problems We See in Burlingame Homes
The word “homes” doesn’t quite fit for commercial work, but the property issues are consistent across Burlingame’s building stock. Here’s what we see most often:
- Protected trees killing the best roof plane. Burlingame’s tree ordinance requires a city permit to prune or remove any private tree above a threshold trunk diameter, and the city arborist frequently denies pruning when the request is motivated by solar access. We always verify tree status before quoting, so you don’t get a proposal we’ll have to reissue around a cedar we can’t touch.
- Undersized electrical panels. Many commercial buildings in Burlingame date from the 1950s and 1960s, and their panels are 100A or less. A solar array plus EV charging or battery storage makes a 200A panel upgrade a near-routine prerequisite. We quote the upgrade upfront, not as a surprise change order.
- Salt-air corrosion on mild-steel hardware. This close to the bay, zinc-plated fasteners and standard racking start showing rust within three to five years. We specify stainless steel and anodized aluminum on every Burlingame commercial job. It costs more up front and saves you a roof leak and a re-rack in year seven.
- June Gloom underproduction. The marine layer that sits over Burlingame from late spring into summer suppresses morning production measurably. If your original installer used inland data, your annual output will miss the model. We re-model with local irradiance data and set honest expectations before you sign.
Pricing for Commercial Solar Installation in Burlingame, CA
Commercial rooftop solar in Burlingame typically runs $2.40 to $3.60 per watt, so a 50kW system lands between $120,000 and $180,000, and a 150kW warehouse system runs $360,000 to $540,000. Solar carports run higher, usually $3.50 to $5.00 per watt, because you’re building the structure and the array. Commercial battery storage adds $800 to $1,200 per kWh of capacity, with most Burlingame businesses adding 30 to 100kWh. Panel upgrades, when needed, add roughly $4,000 to $8,000 depending on your service size. The number we quote is the number you pay.

FAQs - Commercial Solar Installation in Burlingame
Burlingame’s tree-protection ordinance requires a city permit to prune or remove any private tree exceeding a threshold trunk diameter, and the city arborist frequently denies pruning requests when the work is motivated by solar access rather than tree health. In practice, this means your optimal roof plane may be legally shaded forever. We verify tree status before we ever quote, then design around the constraint, usually by moving the array to a rear or side elevation and specifying microinverters or power optimizers to handle partial shading. Call (877) 550-6892 and we’ll check your property’s tree situation at no charge.
Most likely yes. Because Burlingame’s protected mature canopy forces arrays to rear or side elevations with irregular shading patterns, a central string inverter creates a bottleneck where one shaded panel drags down the whole string. We specify Enphase microinverters on nearly every Burlingame commercial job for that reason. It’s a higher per-watt cost, but it’s the right engineering answer. If your specific site has a clean, unshaded plane, we’ll tell you and a string inverter may work fine.
The marine layer suppresses morning solar production from late May into August, reducing annual output by roughly 8 to 12 percent compared to inland Peninsula cities. A production model built on Redwood City data will overstate your savings. We model with Burlingame-specific irradiance data so your payback projection is honest. Most commercial systems in Burlingame pay back in 5 to 8 years after incentives, but that number depends on your rate schedule and usage pattern. Call (877) 550-6892 and we’ll build the model off your actual bill.
If your building’s electrical panel is 100A or less, which is common in Burlingame’s 1950s and 1960s commercial stock, you will almost certainly need a 200A upgrade before interconnection. That adds $4,000 to $8,000 to the project. We identify this during the site survey, not after the contract is signed, and we quote it as a line item so there’s no surprise. If your panel is already 200A, you’re typically fine without an upgrade.
We use stainless steel fasteners and anodized aluminum racking on every Burlingame commercial job. Bay salt air corrodes zinc-plated mild steel within three to five years, leading to premature racking failure and roof leaks, especially on flat roofs where water ponds. The better hardware costs more up front and extends your system’s life by a decade or more. It’s not an upgrade option. It’s our standard specifying practice this close to the bay.
