Fast, Reliable Solar Panel Installation Across Palo Alto
Solar panel installation in Palo Alto typically runs $18,500 to $34,000 before incentives for a 6-10 kW rooftop system, and most projects take four to eight weeks from signed agreement to utility approval. That timeline stretches longer if your home sits inside the Professorville historic district, where the Architectural Review Board wants a say in panel placement before CPAU will even look at your interconnection application. Gus Petrakis has worked enough roofs between 94301 and 94304 to know exactly which streets add a month and which ones sail through. Call (877) 550-6892 and we’ll walk your specific street, your specific roof, and your specific CPAU bill before quoting anything.
We’re not a door-knock crew working a territory. We’re a local shop with a published address, a license number, and an owner who answers his own phone. If you’re in Old Palo Alto, Midtown, or down by the Stanford edge, you’re talking to the person whose name is on the truck.
Why Gus’s Solar Is Palo Alto’s Preferred Solar Panel Installation Company
Gus Petrakis founded Solar Panel Installation work under his own name in 2011, and he still answers the phone. That’s not a line. Homeowners in Professorville and Midtown routinely call back to talk to the same person who walked their roof, and if something goes wrong, one call brings Gus back, not a ticket queue three states away.
Palo Alto homeowners deal with a municipal utility, not PG&E. That changes everything about how a solar quote should be built, what the interconnection paperwork looks like, and which rate schedule actually makes sense. We know CPAU’s process cold because we file through it every month, and we don’t hand that work off to a sub.
Every job carries the 90-Day Done Right Promise in writing. If it’s not done right, Gus makes it right. Calls are answered by a live person 24/7. And the price we quote off your actual CPAU bill is the price you pay, period.
Our Solar Panel Installation Services in Palo Alto
Rooftop Solar Installation
Most Palo Alto roofs we see are either early-1900s Craftsman bungalows with steep pitches and mature tree shade, or mid-century ranch homes and Eichler-style post-and-beam builds with flat or nearly flat roofs. Each requires a completely different mounting strategy, and flashing every penetration properly matters more here than in drier inland cities because winter storms still soak the peninsula. We use LIDAR-based shade modeling before we ever put a panel count on a proposal, especially in the older northern neighborhoods where street trees have had 100 years to grow.

Solar System Design & Permitting
Design work in Palo Alto means pulling the historic overlay map before quoting a roof in 94301. Jobs inside the Professorville historic district can require Architectural Review Board sign-off on panel placement and visibility from the street, which adds several weeks to a timeline that would be straightforward two blocks away. We handle the drawings, the structural review, the CPAU interconnection application, and the city permit package. You don’t chase paper. We do.

Solar Panel Replacement
If your existing array in Palo Alto is underperforming, cracked, or simply ten-plus years old and you’re still on an old inverter, a replacement may make more financial sense than a repair. We’ll run a year-one versus year-25 output comparison off your actual production history and tell you honestly whether replacement pencils out. No brochure math. No upsell pressure.

Roof-Mount & Tile Roof Solar
Clay and concrete tile roofs are common across South Palo Alto and the Eichler tracts, and they demand non-standard racking or ballasted mounts that won’t crack tiles or compromise the roofline. Gus’s crew does the install themselves, and they flash every penetration properly. You’ll know exactly who’s on your roof before they get there, because they’re uniformed, background-checked, and employed by Gus, not a subcontractor.

Common Solar Panel Installation Problems We See in Palo Alto Homes
- Mature tree shading in 94301 and Old Palo Alto: Hundred-year-old street trees make panel placement a real puzzle. A sunny-looking roof at noon can be half-shaded at 10 a.m., and a design that skips LIDAR shading data leaves real money on the table.
- Eichler-era flat and low-slope roofs: Midtown and South Palo Alto are full of post-and-beam homes that can’t take a conventional pitched-roof mount. Ballasted or custom racking is required, and not every installer knows the difference.
- CPAU interconnection delays: Palo Alto runs its own municipal utility, and its application queue and inspection schedule are not PG&E’s. If your installer doesn’t file the CPAU paperwork correctly the first time, you can lose weeks waiting on corrections.
- Historic district review in Professorville: A roof in 94301 doesn’t have to be old to sit inside the historic overlay. ARB sign-off on panel visibility from the street can add time, and an installer who’s never worked the district won’t know to pull that map before quoting.

FAQs - Solar Panel Installation in Palo Alto
We can usually have a site assessment done within three to five business days, and depending on permitting and CPAU queue, installation can start within three to six weeks. Historic district reviews in 94301 can add time, but we’ll tell you that before you sign, not after. Call (877) 550-6892 and we’ll give you a straight timeline.
Yes. We work every Palo Alto ZIP - 94301, 94302, 94303, and 94304 - from the Craftsman bungalows of Professorville to the ranch homes of Midtown and the Eichler tracts of South Palo Alto. No trip charge inside our own county.
If a storm takes out a panel or a microinverter fails and your production drops to zero, call us. A live person answers 24/7, not a voicemail, and we’ll get someone there. If it’s urgent and repairable, we’ll tell you straight whether it’s worth fixing or replacing. Free second opinion on any written estimate.
Installation labor costs are comparable across the peninsula, but your payback math changes because CPAU’s rates and net metering structure aren’t PG&E’s. In Palo Alto, solar makes sense as a hedge against CPAU rate increases and a way to bank your own generation, not as a carbon-footprint argument. We’ll show you the actual payback on your actual bill.
Every job carries the 90-Day Done Right Promise in writing, plus manufacturer warranties from brands like Tesla, Enphase, SolarEdge, and FranklinWH. If something’s not right in the first 90 days, Gus makes it right. After that, you’re still calling the same person, not a warranty department.
If you’re reading this and weighing a solar decision, take two weeks. Think about it. If a salesman needs an answer tonight, the answer is no. When you’re ready, call (877) 550-6892 for a free estimate and we’ll quote the year-25 output, not the day-one brochure number.
