Fast, Reliable Solar Panel Installation Across Claremont
Solar panel installation in Claremont means designing around 100-year-old oaks and protected jacarandas, not just bolting panels to a sunny roof. We’ve been doing exactly that for Claremont homeowners since 2011, and the work starts with your actual utility bill, not a brochure. A typical rooftop system in Claremont runs $18,000-$32,000 before incentives, and most installations take two to three days on-site. Call (877) 550-6892 and Gus Petrakis will walk the numbers with you himself.
Why Gus’s Solar Is Claremont’s Preferred Solar Panel Installation Company
Claremont homeowners tend to ask harder questions than most. They’ve sat through the door-knocker pitch, they’ve seen the glossy estimate that somehow doubled at signing, and they’re done with it. Gus Petrakis is the owner, the name on the building, and the guy who answers when you call. He tells people up front: bring me a bill, I’ll bring you the math. Take two weeks. The price will be the same.
Our crews work throughout Claremont, from the Craftsman bungalows near the Village to the custom homes on the north side near the foothills. We flash every roof penetration properly. We don’t hand work off to subs. The 90-Day Done Right Promise backs every Claremont job in writing: if it’s not right, one call brings Gus back. That’s not a warranty you have to fight for. It’s a person you already have the number for.
Our Solar Panel Installation Services in Claremont
Rooftop Solar Installation
Most Claremont roofs fall into two camps: pre-WWII Craftsman structures with steep pitches and smaller usable planes, or mid-century ranch homes with long, low slopes. Both work, but they need different racking approaches and different panel layouts. We design each array around the roof you actually have, not a stock render. Comp roof, tile roof, flat sections over a garage: we’ve installed on all of them in Claremont.

Solar System Design & Permitting
This is where Claremont gets complicated, and where a lot of out-of-area installers stumble. Claremont’s City of Trees ordinance protects mature oaks and jacarandas, so you can’t just trim a branch that shades your best roof plane. Design has to work around the shade. That means microinverters or power optimizers far more often here than in Pomona or Ontario, where treeless lots make string inverters viable. We also pull permits with the City of Claremont and manage the whole paperwork chain so you’re not chasing the building department yourself.

Solar Panel Replacement
If your existing array is underperforming or panels have failed, we replace them in kind or upgrade you to current-efficiency modules from Enphase, Tesla, or REC. In Claremont, older systems often date to 2010-2015 and were designed for a different net metering rate structure. A replacement is a chance to re-model your production against current utility rates and your actual export profile. We’ll show you the year-25 output, not the day-one brochure number.

Roof-Mount & Tile Roof Solar
Tile roofs are common on Claremont’s mid-century homes and the larger custom builds on the north side. Tile work takes care because cracked tiles leak, and a leak discovered after the first rain is a leak nobody wants. Gus’s own crew handles the mounts and flashing. We don’t send a sub crew you’ve never met. If a tile breaks during install, we replace it. That’s part of the job, not an extra line item.

Trusted Brands We Service in Claremont
We work with equipment we would put on our own roofs: Tesla, Enphase, SolarEdge, FranklinWH, and a short list of others. For Claremont specifically, Enphase microinverters show up on a lot of our quotes because they isolate shade losses from individual modules. That matters when a protected jacaranda throws moving shade across your array for three hours a day. We keep common parts in local inventory, so a failed microinverter or optimizer on a Claremont home gets replaced fast, not ordered from a warehouse two states away. If you already have a system from a previous installer, we service and replace equipment on that too.
Common Solar Panel Installation Problems We See in Claremont Homes
- Protected trees shading the best roof plane. Claremont’s tree ordinance means you often can’t legally remove or heavily trim a mature oak or jacaranda that shades your south roof. String inverter systems lose up to 50% production when even one module gets shaded, so we spec microinverters or optimizers on nearly every Claremont roof with canopy cover.
- Undersized 100-amp electrical panels. Many pre-WWII Craftsman bungalows near the Village and mid-century ranches throughout 91711 still run on original 100-amp service. Claremont’s utility interconnection process will stop a solar permit dead until the panel is upgraded. We handle that upgrade as part of the install, not as a surprise change order.
- East-facing roof planes near the foothills. Homes on the north side near Claremont Wilderness Park often have terrain blocks morning production from the east. Homeowners see lower-than-expected output in the first year and assume something is broken. We model the actual solar window for your specific roof azimuth before we ever quote, so the numbers are honest from day one.
- Tile roof penetrations leaking after out-of-area installs. We get called out to fix this more than we’d like. A national crew flashes a mount wrong on a tile roof, the first Santa Ana rain finds the gap, and suddenly there’s a water stain on the ceiling. The fix is almost always re-flashing and re-seating the mounts. It’s not glamorous work, but it’s the kind of work Gus’s name is on.
Pricing for Solar Panel Installation in Claremont, CA
A typical rooftop solar installation in Claremont runs $18,000-$32,000 before the federal tax credit, depending on system size, panel choice, and whether you need a panel upgrade. If your home still has a 100-amp panel, add $2,500-$4,500 for a 200-amp service upgrade. Solar panel replacement on an existing array runs $120-$280 per panel including labor, depending on the module and racking system. Tile roof work carries a modest premium over comp shingle because of the slower mounting process. For a full reroof plus solar reinstall, budget $8,000-$18,000 for the roofing portion and $1,500-$3,500 for the solar removal and reinstall itself.

FAQs - Solar Panel Installation in Claremont
Yes, in most cases. Claremont protects mature oaks and jacarandas through a city-enforced ordinance that limits significant trimming or removal without approval. You can’t legally clear the canopy just to improve solar production, so the system has to be designed around the shade. We use microinverters or power optimizers on affected roof planes so a shaded branch doesn’t drag down the whole array. Call (877) 550-6892 and we’ll assess what your specific trees actually do to production before you spend a dollar.
If your home still has a 100-amp panel, very likely yes. Most pre-WWII bungalows near the Village and many 1950s-70s ranches in Claremont still run on 100-amp service, and Claremont’s utility interconnection process requires a 200-amp panel before a solar system can be approved. We include the upgrade in our quote from the start, so there’s no surprise change order midway through the permit process. The cost is typically $2,500-$4,500, done by our own crew.
South-facing planes are ideal, but homes on the north side near the Wilderness Park often have terrain that blocks early-morning production on east-facing roofs. A southwest orientation usually outperforms east on those lots. We run a solar window model specific to your roof azimuth and the mountain profile behind your house before we quote, so the numbers reflect reality, not a generic map.
Claremont homeowners are served by Southern California Edison under current net metering rules that credit excess solar production at a lower rate than what you pay for grid power. That means your system should be sized against your actual usage hours, not just your total monthly kilowatt-hours. We build the math off your real bill and current export rates. Bring me a bill, I’ll bring you the math, and you’ll see the year-25 output before you sign anything.
Yes. We remove the array, store the panels safely, and reinstall them after the roof work is complete. In Claremont, where mid-century homes are at the age when tile and comp roofs start needing replacement, this comes up a lot. The removal and reinstall portion typically runs $1,500-$3,500. We coordinate directly with your roofer or handle the whole project if you don’t have one yet. Call (877) 550-6892 for a specific number.
Designing Solar Around Claremont’s City of Trees
Claremont is genuinely different from its neighbors. The city enforces tree protection in a way that Pomona, Montclair, and Ontario simply don’t, and that changes how a solar system has to be designed. On a recent Craftsman bungalow near the Village, a protected 60-year-old oak shaded the entire south roof for most of the afternoon. A string inverter system would have lost half its production to that single tree. Our crew used Enphase microinverters on each panel to isolate partial-shade losses and upgraded the original 100-amp panel before interconnection. Production held at 92% of the unshaded estimate despite the canopy.
That’s the recurring design challenge on Claremont’s north-side foothill streets near the Wilderness Park: the most sun-exposed roof face is often on a lot where the city or an HOA has planted and now protects large canopy trees along the parkway. The ideal roof, the shadiest yard. You can’t remove the trees, so the system has to work around them. That means microinverters or optimizers on nearly every shaded plane, panel-level monitoring, and honest expectations about what partial shade does to annual production. We’d rather tell you the real number and let you decide than sell you a fantasy number and disappear. That’s how Gus has run his solar company from day one.
