AfterFast, Reliable Solar Panel Installation Across Claremont
A rooftop solar system for a Claremont home typically runs $16,500 to $28,000 before the federal tax credit, with most installs completed in two to three days once permits clear. We’re a locally owned solar shop that has installed on everything from pre-WWII Craftsman bungalows near the Village to mid-century ranches below the foothills. If you’re weighing whether solar makes sense on a street with protected oaks and jacarandas, call us at (877) 550-6892 and we’ll talk through what your roof can actually produce.
This page is written for Claremont homeowners specifically. Your trees, your roof planes, your 1950s electrical panel, and your July AC bill all change the math. A generic solar quote won’t account for any of that. Ours does.
Why Gus’s Solar Is Claremont’s Preferred Solar Panel Installation Company
Gus Petrakis founded this company in 2011, and he still answers his own phone. That matters in Claremont, where a lot of homeowners have already been through the door-knocker routine: the rep who quotes $12,000 and then the “revised” contract shows up at $31,000. We don’t work that way. Bring us a year of your SCE bill and we’ll build the estimate off your actual usage, your actual roof, and your actual export rates under the current net metering structure. If a salesman needs an answer tonight, the answer is no. Take two weeks. Think about it. The price will be the same.
We’ve worked on homes throughout the 91711 ZIP code: the Craftsman pockets south of Foothill, the 1950s ranch subdivisions off Base Line and Towne Avenue, the newer customs north of Baughman Road. The crew that shows up is Gus’s own crew, background-checked and uniformed. No subs. No third-party install team from another state. When a Claremont homeowner calls with a post-install question, a live person answers, 24/7.
Local Roots, On Time, Community First, Accountable, Loyal
These aren’t wall-plaque words for us. Gus lives in this region, shops at the same hardware stores, and drives the same freeways you do. When a protected jacaranda shades your south roof, we design around it. When the city’s tree ordinance keeps you from trimming that oak, we don’t argue; we add a panel or two on the west plane and move on. That’s how you build a solar business that lasts 29 years in one place.
Our Solar Panel Installation Services in Claremont
Every Claremont install starts with honest math, not a brochure. Here’s what we handle, from first site visit to final inspection. And remember: every solar job includes the 90-Day Done Right Promise in writing. If it’s not done right, one call brings Gus back.
Rooftop Solar Installation
Most Claremont roofs fall into two camps: older composition shingle on the mid-century homes, and clay tile or concrete tile on the larger foothills customs. Tile requires a different mounting approach entirely: we use tile-replacement flashing, not shim-and-seal shortcuts that leak after two winters. On shingle roofs we pull and re-flash every penetration. A typical Claremont rooftop install of 6kW to 9kW runs $16,500 to $27,000 before incentives, depending on roof type and panel count.
Solar System Design & Permitting
This is where Claremont gets interesting. Because the city protects its mature tree canopy, we can’t just point panels south and call it a day. We model your actual shade conditions across all twelve months, not just June. That means a system designed for a shaded Claremont lot will often carry more panels or different inverter architecture than the same square footage in Pomona would. We handle the City of Claremont permit package, HOA documentation if needed, and all SCE interconnection paperwork. Permitting for a standard Claremont rooftop system typically clears in 3 to 6 weeks depending on the city’s current queue.
Solar Panel Replacement
If you bought solar ten or twelve years ago from a company that no longer exists, you’re not alone. We replace aging or underperforming panels on Claremont homes regularly. A 4kW to 6kW panel replacement, including new mounting hardware and inverter compatibility work, generally runs $9,500 to $16,000. We’ll also tell you honestly if your existing racking is still sound and you only need the panels themselves. Some companies will quote a full tear-off when a panel swap would do. We won’t.
Roof-Mount & Tile Roof Solar
Tile roofs on Claremont’s north-end custom homes need a crew that’s done this before. Every tile we lift gets replaced or swapped for a comp-out flashing so the roof stays weathertight. We work with flat clay tile, S-tile, and lightweight concrete. The cost runs a bit higher than shingle mounts, usually $1,000 to $1,800 extra for a typical 7kW system, because of the added labor and flashing material. It’s worth doing right: a botched tile mount leaks, and you won’t notice until the first big rain.
Solar Interconnection & Utility Approval
SCE’s interconnection process is straightforward if the paperwork is clean and the panel is sized correctly. The bottleneck we see in Claremont is almost always the home’s original 100-amp electrical panel. SCE won’t sign off on a solar interconnect when the main service is undersized, and many of the pre-1970 homes here never got upgraded. We handle the panel upgrade as part of the job when needed, and we’ll flag it during the first site visit so you’re not surprised at week four.

Trusted Brands We Service in Claremont
We install and service equipment from the brands that actually hold up in Claremont’s heat and partial-shade conditions: Enphase microinverters, SolarEdge power optimizers, Tesla batteries, and FranklinWH home backup systems. For partial-shade lots, we lean on Enphase and SolarEdge because they handle shade at the panel level; a string inverter from any brand simply underperforms when a protected oak throws moving shade across the array between 2pm and 6pm. We keep common replacement parts in local stock so a Claremont service call doesn’t wait on a warehouse three states away.
Common Solar Panel Installation Problems We See in Claremont Homes
- Undersized 100-amp electrical panels on older homes. Pre-WWII Craftsman bungalows near the Village and 1950s ranches off Indian Hill Boulevard often carry original main panels. SCE interconnection fails, the project stalls, and the homeowner is left frustrated. We catch this in the first walkthrough and fold the upgrade into the original quote.
- Protected parkway trees casting shifting shade. Claremont’s tree preservation ordinance means that 60-foot oak in your parkway is staying. A string-inverter design will underperform from day one and may trigger rapid-shutdown faults due to partial shading. Microinverter or optimizer systems are the standard here, not the exception.
- Roof planes facing the San Gabriel foothills losing early-morning production. Homes on the north side of Claremont, especially streets near the Wilderness Park, have east-facing roof planes that sit in terrain shadow until mid-morning. A naive azimuth-based estimate overstates output, and the first true-up statement is a rude surprise. We build Claremont-specific production models, not zip-code averages.
- Legacy solar installs from now-defunct companies. A lot of Claremont homeowners bought solar in the early 2010s from out-of-state installers that no longer answer the phone. Panels are 65% through their useful life, inverters are failing, and no one will service them. We repair and replace orphaned systems regularly, and we quote the year-25 output, not the day-one brochure number.

FAQs - Solar Panel Installation in Claremont
No. Claremont’s tree protection ordinance restricts significant trimming of protected oaks and jacarandas, but it does not block solar installation. What it means is that your system needs to be designed around partial shade, not after it. We use Enphase microinverters or SolarEdge power optimizers on nearly every shaded Claremont roof, and we’re honest when a roof plane simply won’t produce enough to justify the panel count. Call (877) 550-6892 for an honest read on your tree-shaded roof.
In almost every case, no. A 100-amp main service panel does not leave enough headroom for a solar interconnection under SCE’s current requirements, and the city inspector will not sign off on a 100-amp bus bar with a 40-amp solar breaker. We quote the panel upgrade as part of the solar install when we see one coming, which is often: legacy panels are extremely common in the 1950s ranch homes around Claremont.
Claremont sits at roughly 1,100 feet elevation at the foot of the San Gabriels. East-facing roof planes in the north part of the city, near the Wilderness Park, sit in mountain shadow until the sun clears the terrain to the east. It’s an hour to ninety minutes of lost morning production every day, which adds up over a year. Pomona, sitting flat to the southeast, does not have this terrain shadow. We run Claremont-specific shade and terrain models, not generic PVWatts defaults.
Yes. Net metering is governed by SCE and the CPUC, not by city, so Claremont and Ontario customers are under the same net billing tariff structure. What differs is your home’s production profile: Claremont’s protected shade and foothill terrain change how many kilowatt-hours you actually generate, which changes what you export and what you pay at true-up. That’s why we size Claremont systems off your bill and your measured shade, not a city-average table.
Panels from REC, Qcells, and Panasonic carry 0.25% to 0.45% annual degradation rates under normal conditions. Partial shade does not meaningfully accelerate panel degradation; what it does is reduce production whenever the shade hits. The right inverter architecture, panel-level or optimizer-level, recovers nearly all of that lost production. Panels on shaded Claremont roofs typically still hit 92% of original output at year 20, same as anywhere else.
