AfterSolar Services in Hillsborough, CA
Solar in Hillsborough works differently than it does a few miles east in San Mateo or Burlingame. The lots are bigger, the roofs are tile or slate, the trees have been growing for seventy years, and the Architectural Review Board has a say in where panels go and what they look like. If you’re reading this, you probably know that already, or you’re about to. We’re Gus’s Solar. We’ve been handling Solar Panel Installation in Hillsborough and Peninsula communities since 2011, and we answer the phone when you call: (877) 550-6892.

Why Hillsborough Homeowners Choose Gus’s Solar
The neighborhoods we work in most often are Carolands, Tobin Clark, and Country Club Manor (just off Ralston Avenue), along with the upper stretches near White Road and Black Mountain Road. These are estate homes, and owners here tend to do their homework before anyone sets foot on the roof. That’s fine by us. Gus Petrakis publishes his name, address, and license number, and he’s the one who shows up to walk the property. No sales rep with a tablet and a script.
What we hear from Hillsborough clients is the same thing in different words: a national installer quoted one number, pushed for a signature by Friday, and went quiet when the permitting questions started. We don’t do that. You’ll get a price built from your actual PG&E bill, a proposal that accounts for the ARB’s aesthetic requirements, and a live person on the phone any hour you call. Our crew is background-checked, uniformed, and we flash every roof penetration properly on a tile roof the first time, no callbacks needed.
We also stand behind the work with something we call the 90-Day Done Right Promise. If something isn’t right after install, you make one call and Gus comes back. It’s in writing on every job, and it’s the reason most of our Hillsborough business comes from neighbors referring neighbors.
Solar Services We Offer in Hillsborough
Solar Panel Installation
Installing panels on a Hillsborough estate roof means specialty racking for Spanish tile or slate, all-black low-profile modules that satisfy ARB review, and individual shade analysis for each roof plane. We size the system for how you actually live: pool equipment, EV chargers, home automation, and all the rest.
Learn more about our Solar Panel Installation in Hillsborough.
Solar Battery Storage & Backup
Hillsborough’s electrical loads don’t match the rest of the Peninsula. Three-car garages with two EVs, heated pools running year-round, whole-home systems drawing constant power. Hillsborough Solar Battery Storage & Backup isn’t a nice-to-have here; it’s the difference between a system that covers you during PG&E outages and one that sits idle when you need it most.
Learn more about our Solar Battery Storage & Backup in Hillsborough.
Solar Panel Cleaning
Mature oak and redwood canopy across 94010 means pollen, sap, and leaf debris settle on panels faster than in open neighborhoods. Clean panels produce. Dirty ones don’t. We provide Hillsborough Solar Panel Cleaning without damaging the panel coatings or the tile beneath them.
Learn more about our Solar Panel Cleaning in Hillsborough.
EV Charger Installation
Most Hillsborough garages can handle two EVs, and the electrical panel needs to be ready for that from day one. We handle EV Charger Installation - Hillsborough, upgrade panels where needed, and coordinate the work so your solar system and chargers actually talk to each other.
Solar Panel Maintenance & Monitoring
We monitor the systems we install, and Gus is the one who calls you when output drops, not some automated email. Annual maintenance visits catch microcracked panels, loose connections, and underperforming strings before they become expensive problems.
Solar Panel Repair
Tile roofs make panel repair in Hillsborough trickier than flat comp shingle jobs. We carry the specialty flashing and mounting hardware needed for Spanish tile and slate, so the repair is done correctly the first time, without leaving a leak behind.
Commercial Solar Installation
Hillsborough bans commercial activity within town limits, but we serve adjacent commercial properties in San Mateo and Burlingame with the same owner-operated standard. If you own a commercial building just over the border, we’d be glad to talk.
Neighborhoods We Serve in Hillsborough
We work throughout all of Hillsborough’s residential areas, including:
- Carolands - the estate properties off Ralston Avenue east of the golf course
- Tobin Clark - historic homes near Hillsborough’s southern edge
- Country Club Manor - larger lots with heavy tree canopy
- White Road and Black Mountain Road - elevated properties with better sun exposure but complex rooflines
- West Hillsborough - homes along the 280 corridor with mixed sun and shade patterns
Typical response time in Hillsborough is same-day or next-morning for phone calls and estimates. Repair visits can often be scheduled the same week.
Why Hillsborough’s Climate & Housing Affect Solar
Hillsborough is one of the only Peninsula cities where the Architectural Review Board holds approval authority over every exterior change to a private home, including solar panel placement, color, and profile. That means a system design has to look right before it can even be permitted. In practice, that translates to all-black low-profile modules, careful array placement that avoids street views, and a strong preference for panels that sit close to the roofline rather than on raised racking.
Combine that with the housing stock itself. Many Hillsborough homes were built between the 1940s and 1980s in Spanish Colonial, Mediterranean, or California Ranch style, with tile or slate roofs. Tile requires specialized mounting hooks that attach to the underlayment, not the tile itself. Slate is even more delicate. A contractor who has only ever drilled into composition shingle will crack tiles and leave you with leaks. We’ve corrected enough of those jobs to know exactly what not to do.
The climate matters too. Hillsborough sits on the eastern foothills above Burlingame, so it gets more sun than ocean-facing towns, but summer marine layer still suppresses morning production. That makes south and southwest-facing roof sections disproportionately valuable here, and it’s why we run individual shade analysis on every roof plane, not a single number for the whole house.
Then there’s the tree canopy. Decades-old oaks and redwoods on large lots create shifting shade patterns that a generic solar model won’t catch. Nearly every Hillsborough system we install includes power optimizers or microinverters for that reason, even on south-facing roofs that look fine from the ground.
Pricing for Solar in Hillsborough
Solar costs in Hillsborough run higher than the Peninsula average, and there’s no way around it. Tile and slate racking adds labor. ARB compliance adds design hours. Large estate systems with battery storage and panel upgrades add equipment. A typical ground-floor Hillsborough install for a 20-30 kW system with two to three batteries lands between $90,000 and $160,000 before the federal tax credit and any applicable incentives.
Smaller systems for ranch-style homes with simpler rooflines can come in under that range. Panel cleaning runs between $350 and $600 per visit depending on array size and roof access. Repair costs vary widely, but we offer a free second opinion on any written estimate, and we never charge a trip fee within our county.
The number we quote is the number you pay. No add-ons at the door. We’ll build the estimate off your actual bill, not a brochure. Call (877) 550-6892 and we’ll send someone out to look at your roof, your panel, and your usage.

FAQs About Solar in Hillsborough
Yes, the Hillsborough ARB reviews all exterior changes to private residences, including solar panel placement, color, and profile. We prepare ARB-compliant submittal packages as part of every Hillsborough install, with all-black low-profile panels that are designed to clear aesthetic review. Call (877) 550-6892 and we’ll explain what the board expects before you commit to anything.
Most Hillsborough solar projects run 20 to 40 percent higher than comparable systems in Burlingame or San Mateo because of tile and slate racking, ARB compliance work, and the larger system sizes these homes require. A 20-30 kW system with battery storage typically lands between $90,000 and $160,000 before tax credits. For an exact quote on your home, call (877) 550-6892. Estimates are free and based on your actual bill.
Yes, we use specialty mounting hardware designed for Spanish tile and slate, and we flash every penetration properly the first time. This is not a job for a crew that learned on composition shingle. Call (877) 550-6892 and we’ll come out to look at your specific roof.
In Hillsborough, almost certainly yes. The mature oak and redwood canopy here means shade patterns shift throughout the day and across seasons. Without panel-level optimization, one shaded panel drags down the whole string. We include optimizers or microinverters on nearly every Hillsborough system. Call (877) 550-6892 and we’ll explain what your roof actually needs.
Usually yes. We respond to Hillsborough calls same-day or next-morning, and we can often schedule a site visit within the same week. There’s no trip charge inside our county. Call (877) 550-6892 and a live person answers, any hour.

What Hillsborough Customers Say
"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"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"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."
- Ferdinand Kaltenbrunner
