Solar in Los Altos isn’t a one-size-fits-all project, and anyone who tells you otherwise is selling from a brochure. The city’s mature oaks and redwoods, its 1950s-era ranch homes, and the way the marine layer sneaks up the Peninsula in early summer all change what a system should look like and what it will actually produce. You need an installer who knows which side of your roof the city will let you use. When you call (877) 550-6892, you get a real person who knows Los Altos, not a call center three states away.

Why Los Altos Homeowners Choose Gus’s Solar
Gus Petrakis started this business in 2011 because he was tired of watching national outfits sell people solar systems that looked great at signing and underperformed by year three. He puts his name on the truck, publishes his license number, and answers his own phone. Los Altos homeowners in neighborhoods like Woodland Acres and North Los Altos have seen the same pattern we have: a door-knocker quotes one number, the contract says another, and the crew that shows up is a sub from who knows where. That doesn’t happen with us. Our team handles every Solar Panel Installation - Los Altos, every flashing detail, every penetration seal. Gus checks the work himself. If it’s not done right, the 90-Day Done Right Promise means one call brings him back. And when your system underproduces in July because the marine layer is lingering, we’re the ones calling you, not the other way around.
Solar Services We Offer in Los Altos
Everything we do in Los Altos is grounded in the same idea: honest numbers off your actual utility bill, not a glossy estimate from a sales deck. Here’s what that looks like in practice.
Solar Panel Installation
Most Los Altos installs are east- or west-facing by necessity, not choice. The city’s protected oaks force arrays onto roof sections that catch morning or afternoon sun, which means panel selection and optimizer layout matter more than they would on an open south-facing roof in a newer subdivision. We build systems for year-25 output, not the day-one brochure number.

Solar Battery Storage & Backup
Many Los Altos homes still run on original 100-amp service panels. That’s an honest constraint, not a scare tactic. Adding Los Altos Solar Battery Storage & Backup and an EV charger to that setup typically means a panel upgrade first. We quote the whole picture up front so the battery actually does what you expect when the grid fails.

Solar Panel Cleaning
Under a canopy of oaks and redwoods, Los Altos panels collect dust, sap, and leaf debris faster than panels in open-lot developments. A visibly dirty array in the 94022 zip can lose 10-15% of its output before anyone notices. Our Los Altos Solar Panel Cleaning service removes debris without scratching the glass and checks connections while we’re up there.

EV Charger Installation
Los Altos has one of the highest EV adoption rates in the Bay Area. EV Charger Installation in Los Altos tied to your solar array means you’re driving on sunshine instead of grid electricity at peak rates. We wire the circuit, mount the charger, and size everything so your main panel doesn’t trip when the car, the AC, and the dryer all kick on at once.
Solar Panel Maintenance & Monitoring
Systems fail quietly. A string goes down, a microinverter stops reporting, a tree grows three feet and shades an entire panel row. You won’t hear it, but your utility bill will feel it. We monitor your production and come out when the numbers drift. In Los Altos, that monitoring catches shade problems early, before a full summer of production is lost.
Solar Panel Repair
Whether it’s a cracked panel, a chewed wire from a squirrel, or an inverter that’s been dead for a month without anyone noticing, we fix it. You don’t need to hold a national warranty phone tree hostage for two weeks. We come out, diagnose the problem, and give you an honest answer on whether repair or replacement makes sense. Estimates are free.
Commercial Solar Installation
Small offices and professional buildings along El Camino Real and Foothill Expressway have the same tree-shading realities as Los Altos homes, with the added wrinkle of flat roofs and stricter permitting. We handle the engineering and paperwork so the system produces from day one without surprising code issues.
Neighborhoods We Serve in Los Altos
We work throughout Los Altos, and we’re familiar with the quirks of each pocket of town. Typical response time for a call is same day or next morning, depending on the issue.

Why Los Altos’s Climate & Housing Affect Solar
Los Altos sits on the Santa Clara Valley floor, tucked into a slight rain shadow from the Santa Cruz Mountains. You get meaningfully more annual sun than coastal Palo Alto or Menlo Park, which is good. But the marine layer pushing inland through the Dumbarton corridor can suppress June and July production in ways a generic Clear Sky model misses. If someone quotes you a sunny-summer number from a national database, take it as optimistic. We pull your actual usage and model against real Peninsula weather patterns, not what the panel datasheet says under laboratory light.
Then there’s the tree problem. Los Altos doesn’t just protect its mature oaks and redwoods on paper. City arborists actively flag permit applications where a proposed tree trim touches a protected heritage oak, and those flags stall interconnection timelines by weeks. We pull the city’s protected-tree map before quoting any job so you know which roof sections are realistically usable without a separate arborist report. Most 1950s-70s ranch homes in the 94024 and 94022 zips have low-pitched gable or hip roofs, which limits tilt and sometimes restricts racking. You need an installer who has seen this exact roof-and-tree combination a hundred times, not a crew visiting from Fresno for the week.

FAQs About Solar in Los Altos
Most residential installs in Los Altos run between $12,000 and $24,000 before incentives. The spread comes from roof complexity, panel brand (we work with Qcells, REC, and SunPower among others), and whether a service panel upgrade is needed. Call (877) 550-6892 for a quote built off your actual usage and roof reality, not a brochure number.
That’s the single biggest factor on most Los Altos jobs. Mature oaks and redwoods shade large portions of many roofs, and the city’s heritage tree ordinance protects many of those trees from removal or heavy trimming. We pull the protected-tree map before quoting so you know which roof sections are usable without an arborist report. In most cases, an east- or west-facing array with panel optimizers beats a south-facing array under tree cover.
In most cases, yes. A live person answers our phone 24/7, and our typical response in Los Altos is same day or next morning. Call (877) 550-6892 and tell us what’s going on. There’s no trip charge inside Santa Clara County.
Honestly, often yes. A large share of Los Altos homes still run on original 100-amp service panels, from the 1950s through the mid-1970s. Adding solar plus a battery plus an EV charger typically pushes past that rating. We’ll tell you up front if your panel needs to go to 200 amps, and we include that cost in the quote instead of springing it as a surprise change order.
It depends on the age and brand. A failed microinverter or a single cracked panel is usually a straightforward repair, in the $175-$800 range. If the array is 20 years old and output has degraded significantly, replacement may pencil out better. We’ll give you an honest recommendation either way, and a free second opinion on any written estimate you already have.

What Los Altos Customers Say
"Honest quoting and good workmanship. He is not the cheapest quote I got, by some way, and he told me that himself and explained what the difference bought. I chose him anyway and I am glad."
- Alistair Fennimore"The install itself was excellent and the system performs as modelled. Permitting and the utility interconnection took about four months, most of it out of his hands, though the waiting was still frustrating."
- Marguerite Ostrowski"Told me straight that a battery did not make sense for how we use power and sold me the array without it. He talked himself out of a good deal of money that afternoon."
