AfterSolar Services in San Mateo, CA
If you’re in San Mateo and your PG&E bill has climbed past $300 a month, you’re not imagining it. The combination of NEM 3.0 export rates slashed by roughly 75% and a microclimate that swings between fog belt and full sun from one ZIP code to the next means solar here has to be planned with real care, not a generic roof survey. We’re Gus’s Solar, and we answer the phone at (877) 550-6892. Gus Petrakis owns this company, puts his name on every job, and will tell you straight whether solar makes sense for your specific block in San Mateo before you spend a dollar.

Why San Mateo Homeowners Choose Gus’s Solar
We’ve been a locally owned, owner-operated shop since 2011, long enough to know that a 1920s bungalow near downtown San Mateo and a 1970s rancher out in 94404 are completely different jobs. That’s why we quote every system off your actual utility bill and the real shading profile of your roof, not a regional average. The neighborhoods we visit most often: the tree-lined hillside streets of 94402, where mature eucalyptus dictates panel layout, and the bay-adjacent flats of 94404, where the marine layer burns off by mid-morning and the math gets considerably friendlier.
What keeps people calling us back is simple. The price we quote is the price you pay. Take two weeks to think about it and the number won’t change. If a salesman needs an answer tonight, the answer is no. And if something isn’t right after install, our 90-Day Done Right Promise means one call brings Gus back, in writing, on every solar job we do.
Solar Services We Offer in San Mateo
Solar Panel Installation
Every installation starts with your bill and your roof, not a brochure. We handle design, permitting, and the entire install with Gus’s own crew, and we quote the year-25 output so you know what your panels will actually produce over decades, not just on day one.
Learn more about our Solar Panel Installation in San Mateo.
Solar Battery Storage & Backup
With NEM 3.0 paying so little for exported power, the smart San Mateo setup pairs panels with a battery. We install FranklinWH and other leading storage systems sized to carry your refrigerator, router, and a few lights through the next PG&E outage without blinking.

Solar Panel Cleaning
San Mateo’s dry summers and coastal air leave a film on panels that can shave 5 to 15 percent off output. We clean panels without harsh chemicals or ladders dragging against your roof rails, and we’ll tell you honestly whether your array actually needs it yet.

EV Charger Installation
Charging at home beats hunting for a station on El Camino Real. We install Level 2 chargers with the panel work done correctly the first time, whether that means a simple circuit or a panel upgrade on an older downtown San Mateo home.
Call (877) 550-6892 for a quote on EV charger installation in San Mateo.
Solar Panel Maintenance & Monitoring
If your system underproduces, you shouldn’t be the one to notice it. Gus monitors every system we install and will be the one who calls you when the numbers drift, not the other way around.
Call (877) 550-6892 to have us check your San Mateo system’s production.
Solar Panel Repair
Microinverters fail, connections loosen, and squirrels nest under arrays. We repair systems others installed too, and a free second opinion on any written estimate means you’ll know exactly what’s wrong before you decide to spend anything.
Call (877) 550-6892 for solar panel repair in San Mateo.
Commercial Solar Installation
Warehouse and office roofs on the east side of San Mateo have the square footage to offset serious energy costs. We design commercial arrays that pencil out against PG&E demand charges and actual usage, not wishful production math.
Call (877) 550-6892 for a commercial solar assessment in San Mateo.
Neighborhoods We Serve in San Mateo
We work all over San Mateo, and we usually have a tech to your door same day or next morning for repairs. A few of the neighborhoods where you’ll see our truck most often:
- Baywood (94402) - hillside shade and eucalyptus require careful panel placement
- Shoreview (94404) - flat bay-fill lots, fast marine layer clearing, and larger roof planes
- North Central (94401) - older homes, frequent panel upgrades, and Spanish-tile roofs
- Sugarloaf (94402) - steep lots and forested streets where microinverters earn their keep
Why San Mateo’s Climate & Housing Affect Solar
San Mateo has the sharpest east-west microclimate divide on the Peninsula. The bay-facing homes in 94404 and eastern 94403 see the marine layer burn off by mid-morning and routinely beat generic solar calculators on annual output. But drive ten minutes west into the 94402 hillsides and you’re in the coastal fog belt, where the overcast lingers until noon and shaves meaningful peak production hours every single day. A company using a regional average to size your system gets one of those neighborhoods wrong. We size San Mateo systems neighborhood by neighborhood, because that’s the difference between a system that pays for itself and one that doesn’t.
The housing stock matters just as much. Downtown San Mateo and much of 94402 are dense with 1920s through 1950s Craftsman bungalows and Spanish-tile stucco homes still running 60 to 100-amp electrical panels. In those houses, the panel upgrade is often the first real cost in a solar quote, and it can surprise you if your installer didn’t look at the panel before pricing. Out in the 1960s and 70s bay-fill tracts of 94404, panels are generally newer and roofs are simpler, making them comparatively easy solar candidates. None of this shows up in a national company’s satellite estimate. It shows up when you send a crew that knows San Mateo.
Pricing for Solar in San Mateo
Solar pricing in San Mateo runs higher than the national average, partly due to Peninsula labor and permitting costs and partly due to the dense shade conditions that push many installs toward microinverters or DC optimizers. Here’s what we see:
- Residential panel installation (before tax credit): $15,000 - $28,000 depending on roof complexity and shading
- Battery storage add-on: $9,000 - $16,000 depending on capacity and brand
- Panel upgrade (when needed): $2,500 - $4,500 on older San Mateo homes
- Solar panel cleaning: $150 - $350 per visit based on array size and access
- Diagnostic service call: No trip charge inside San Mateo County
We offer a Senior and Veteran discount of 10% that never expires, plus $40 off any repair over $200. Bring us a bill and we’ll bring you the math. Call (877) 550-6892 for a free estimate built off your actual usage.

FAQs About Solar in San Mateo
Most San Mateo residential solar installations run between $15,000 and $28,000 before the federal tax credit, with battery storage adding $9,000 to $16,000. Your exact number depends on your roof’s shading profile, your current panel, and whether your neighborhood sits in the fog belt or the bay-side sun band. Call (877) 550-6892 for a quote built off your actual bill, and take two weeks to think about it.
If your system is under 10 years old and the issue is a single failed microinverter or a loose connection, repair is almost always the cheaper path, typically $200 to $800. If your array uses outdated string inverters and multiple components are failing, replacement with modern equipment may pencil out better. We’ll give you a straight answer after one diagnostic visit, no trip charge inside the county.
PG&E’s NEM 3.0 cut export credit rates by about 75% starting in April 2023, which means the electricity you send back to the grid earns a fraction of what it once did. In San Mateo, where ample afternoon sun in 94404 can produce a lot of excess power, a battery lets you store that generation and use it in the evening instead of selling it cheap and buying it back at full rate. For most new installs here, a battery is what makes the payback work.
Sometimes, but not often. The 1920s to 1950s homes in 94401 and much of 94402 often run 60 to 100-amp panels, and adding a solar system plus EV charger usually exceeds that capacity. We’ll inspect your panel before we quote so you’re not surprised mid-project, and if an upgrade is needed, our crew does that work directly rather than handing it off to a subcontractor.
For repairs, we typically send a technician same day or next morning. For new installations, design and permitting in San Mateo generally take 2 to 4 weeks before installation begins. Call (877) 550-6892 and Gus will give you a realistic timeline, not a salesman’s promise.
Talk to a Real Person in San Mateo
When you call (877) 550-6892, a live person answers. Not a voicemail, not a ticketing queue, not someone in another state reading a script. If solar in San Mateo makes sense for your roof and your bill, Gus will tell you. If it doesn’t, he’ll tell you that too. That’s how we’ve done it since 2011, and it’s why homeowners from Baywood to Shoreview keep our number in their phones.

What San Mateo Customers Say
"Panel level monitoring so I can see each one, proper stainless clips under the array rather than zip ties, and he walked me under it with a torch to show me before he signed off."
- Cassius Delacroix"Gus's own crew did the install. Not a subcontractor who had never met him, which is what the big outfit quoted me and could not tell me who would actually be on my roof."
- Aurelia Santibanez"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
