AfterCommercial Solar Installation in Burlingame: What It Costs and What Actually Matters Here
Commercial solar in Burlingame runs $80,000 to $450,000 for most rooftop and carport systems before incentives, with the final number driven by roof age, panel service size, and how much of your roof sits under a protected tree. A 50kW warehouse array typically lands between $140,000 and $190,000. Battery storage adds $30,000 to $120,000 depending on capacity. If you’re wondering whether the numbers pencil out, call Gus at (877) 550-6892 and bring us a recent PG&E bill. We’ll show you the year-25 math off your actual usage, not a brochure estimate.
Burlingame is not San Mateo. It’s not Millbrae. The tree ordinance alone changes how every commercial array gets designed, and the marine layer off the bay changes what it actually produces. This page explains what that means in real dollars.
What Burlingame’s Tree Ordinance Does to Commercial Solar Design
Here’s the detail most installers won’t tell you until after you’ve signed. Burlingame requires a permit to prune or remove any private tree above a threshold trunk diameter, and the city arborist routinely denies pruning requests when the stated reason is solar access rather than tree health. In neighboring San Mateo or Millbrae, a commercial property owner can often trim a shading oak and move on. In Burlingame, that mature redwood or deodar cedar shading your south-facing roof plane is legally untouchable.
That changes the entire design conversation. We can’t plan around a future trim. We plan around the tree as it stands today and as it will grow over 25 years. On a 1950s warehouse near Broadway and Rollins Road, our crew found the original clay tile roof and a 75-foot deodar cedar throwing shade across the south plane. The city denied pruning, so we repositioned the array to the east elevation, used tile-replacement mounting, and paired Enphase microinverters with a 200A panel upgrade to offset the morning marine layer and stay code-compliant with rapid shutdown. The system works. The tree stays. The customer knows exactly what they’re getting.
This is why you need a Burlingame installer who has already worked through these denials. We have. You can read more about our full Commercial Solar Installation process, but the short version is this: we check tree status before we quote, not after.
Why Gus’s Solar Is Burlingame’s Preferred Commercial Solar Installer
Gus Petrakis founded this company in 2011 and has kept his name on the truck, his address published, and his phone answered by a live person ever since. No call center. No ticketing portal. When a Burlingame property owner calls at 9 p.m. with a ground-fault alert, Gus or someone on his crew picks up.
Our Commercial Solar Installation in Burlingame work covers warehouses off Rollins Road, retail buildings along Broadway, auto shops in the industrial corridor near the bay, and office buildings throughout 94010 and 94011. We know which roofs in the Easton Addition have original clay tile. We know that buildings along the Bayshore frontage get hammered by salt air in ways that Hillsborough properties don’t. That local knowledge means our quotes account for the real conditions, not a generic California template.
Every Burlingame job is backed by the 90-Day Done Right Promise in writing. If it’s not right, Gus makes it right. One call brings him back. That’s the standard, and it applies to a 20kW rooftop array the same as a 200kW carport system.
Key takeaways for Burlingame property owners:
– Tree-protected shade is a design constraint here, not a trimming item
– Salt-laden air from the bay corrodes mild-steel racking within five years
– June Gloom suppresses morning production from May through August
– Most pre-1980 buildings need a panel upgrade before interconnection
– We verify all of this during a free site survey, before you sign anything
Our Commercial Solar Services in Burlingame
Commercial Rooftop Solar
Rooftop arrays on Burlingame’s flat commercial roofs are the workhorse here, but roof age and material dictate the mounting approach. Many of the 1920s-through-1950s commercial buildings along Broadway and Burlingame Avenue still have original clay or concrete tile, which requires tile-replacement mounts and slows installation compared to composition shingle. Expect a 50kW rooftop system to run $140,000 to $190,000 in Burlingame, with tile-replacement mounting adding roughly $4,000 to $9,000 depending on overage and roof condition.
Commercial Battery Storage
Battery storage matters more in Burlingame than in most Peninsula cities because PG&E’s time-of-use rates punish afternoon and evening draw, and the marine layer already trims your morning production. A FranklinWH or Tesla Powerpack system sized for a small commercial building runs $30,000 to $80,000. Larger facilities needing 100kWh or more of usable storage should budget $90,000 to $120,000. The batteries let you bank what your array does produce and discharge it when rates spike.
Commercial Solar Maintenance
Salt air is the quiet killer in Burlingame. Mild-steel racking, bolts, and clamps corrode within five years on bay-facing properties, loosening rails and triggering ground-fault alerts that shut systems down. Our maintenance program includes annual torque checks, corrosion inspection, and infrared scanning to catch failing connections early. A maintenance visit runs $300 to $600 depending on system size, and we stock replacement hardware locally so turnaround is days, not weeks.
Solar Carport Installation
For Burlingame properties where rooftop space is limited or shaded by protected trees, carports turn parking areas into generation capacity. Carport solar runs $4.50 to $6.50 per watt installed, meaning a 100kW carport typically lands between $450,000 and $650,000. The steel structure also gets the same salt-air treatment: hot-dip galvanized or powder-coated steel, no bare mild steel anywhere.

Common Problems We See on Burlingame Commercial Solar Jobs
- Arrays built under protected tree shade. A system placed on a roof plane that’s shaded after 10 a.m. by a protected oak or redwood can produce 40% below the initial estimate, leaving the owner with a true-up bill they weren’t prepared for. We check tree status and run shade models before we quote.
- Mild-steel hardware corroding inside five years. Bay salt air attacks untreated racking quickly. Loose rails and ground-fault alerts follow. We spec stainless or anodized aluminum hardware on every Burlingame job as a default, not an upgrade.
- Undersized electrical panels on older buildings. Most 1940s-through-1970s commercial buildings around Burlingame Avenue and Broadway have 100A or 200A service. A 50kW rooftop system needs 400A or more, and PG&E won’t approve interconnection until the service upgrade and transformer study are done. We include that upgrade in the quote so there’s no surprise.
- June Gloom production shortfalls. Burlingame sits in the marine layer corridor between SFO and the bay. Summer fog suppresses morning production from late May into August, so any production model calibrated for Redwood City or San Jose will overstate annual yield here. We build our models off Burlingame-specific weather data.

Trusted Brands We Service in Burlingame
We install and service Enphase microinverters, Tesla batteries and inverters, SolarEdge power optimizers, and FranklinWH storage systems across Burlingame. For commercial roofs dealing with tree-protected partial shading, we default to Enphase or SolarEdge module-level electronics because string inverters leave too much production on the table when a single deodar cedar throws shade across half the array. We stock replacement parts and consumables locally, which means a failed microinverter on a Broadway office building gets swapped in days, not the weeks some national outfits take to ship from an out-of-state warehouse.
How the June Gloom Marine Layer Changes Burlingame Commercial Solar
Burlingame sits in the marine layer corridor between SFO and the bay. From late May through August, morning fog suppresses solar production until 10 or 11 a.m. most days. That is not a minor footnote. A production model calibrated to inland Peninsula cities like Redwood City or Palo Alto will overstate Burlingame annual yield by 8 to 15 percent, and if your system was sized on that inflated number, your true-up bill will show it.
We build Burlingame-specific production models using local weather station data and years of actual output from existing Burlingame arrays. That means the month-by-month production estimates we show you are honest numbers for this city, not a statewide average. The marine layer also makes east-facing arrays more valuable here. When morning sun is suppressed, an east plane starts producing earlier than a west plane, and with Enphase microinverters on every module, partial fog doesn’t knock out the whole string.

FAQs - Commercial Solar Installation in Burlingame
Does Burlingame’s tree ordinance actually block commercial solar installations if a protected tree shades the building?
No, it doesn’t block installations, but it does force design changes. The city requires a permit to prune or remove any private tree above a threshold trunk diameter, and the arborist often denies pruning requests when solar access is the stated reason. That means the array must be positioned around the shade, or the system must use microinverters and power optimizers to limit the production loss on shaded modules. We check tree status before we quote so the proposal you sign is the system that actually gets built. Call (877) 550-6892 for a free site survey.
How much does the June Gloom marine layer cut into a commercial solar array’s annual kWh offset in Burlingame?
Between 8 and 15 percent, depending on the array’s orientation and how close the building sits to the bay frontage. Buildings in 94010 right along the water see heavier fog and more production loss than buildings up near the Hillsborough border. We model every Burlingame project off local weather data, not a generic California production calculator, so the year-one estimate you see matches what the system actually produces.
Why do we need microinverters or power optimizers instead of a string inverter on a Burlingame commercial roof?
Because tree-protected shade and morning fog are routine here, not edge cases. A string inverter treats all modules as one unit, so a single shaded panel drags down the whole string’s output. Enphase microinverters or SolarEdge power optimizers isolate each module, so a branch-shaded panel doesn’t cut production across the array. On most Burlingame commercial roofs we quote, module-level electronics are the default, not an add-on.
Will salt air from the bay really corrode our commercial racking that fast?
Yes, on untreated mild steel. Bay-facing properties in Burlingame’s industrial corridor regularly show corrosion on bolts, clamps, and rail connections within five years of install. That leads to loose rails and ground-fault alerts that shut the system down. We spec stainless or anodized aluminum hardware as standard on every Burlingame job, and our maintenance program includes annual corrosion inspection to catch problems before they kill production.
Is a 200A panel upgrade really required for a commercial solar-plus-EV-charger project in Burlingame’s older buildings?
Almost always, yes. Most commercial buildings from the 1920s through 1970s around Burlingame Avenue, Broadway, and the industrial corridor have 100A or 200A service. A rooftop array alone often needs 400A or more once you account for load calculations and PG&E’s interconnection requirements. Add EV chargers and the math gets tighter. We include the service upgrade and any transformer study in the quote up front so there’s no change order after you’ve signed.
