Why Claremont Homeowners Choose Gus’s Solar
You’ve probably had a solar rep knock on your door in Claremont with a tablet and a pitch about “free solar.” Most of those outfits are gone by the time your system needs service. Gus is different. He puts his name on the building, publishes his license number, and tells every customer the same thing: take two weeks, think about it, the price will be the same. That’s not a sales tactic. That’s how a neighbor operates.
We’ve installed and serviced systems throughout the Village, up in the foothill streets near the Claremont Wilderness Park, and across the mid-century ranch neighborhoods south of Foothill Boulevard. Homeowners consistently tell us the same thing: Gus quoted a number, showed up when he said he would, and the final bill matched the quote. No surprises at the door. No subcontracted crew showing up unannounced. The people on your roof are background-checked and wear Gus’s Solar uniforms, and Gus himself is a phone call away if anything ever looks off.
We run on five values we don’t just hang on the wall: Local roots, On time, Community first, Accountable, and Loyal. It means when your system underperforms in year four, you’re not filing a ticket with a portal. You call Gus. He picks up.
Solar Services We Offer in Claremont
Solar Panel Installation
We design and install rooftop systems around Claremont’s shade realities, using microinverters or power optimizers where partial tree cover demands panel-by-panel output. Gus quotes the year-25 production number, not the day-one brochure figure. Learn more about our Solar Panel Installation in Claremont.

Solar Battery Storage & Backup
With Claremont’s summer temperatures regularly crossing 100°F, batteries keep your AC running when SCE shuts power down during wind events. We size battery banks to your actual evening load, not a generic template. Learn more about our Solar Battery Storage & Backup in Claremont.

Solar Panel Cleaning
Claremont’s tree canopy means pollen, sap, and leaf litter accumulate faster on panels than in most of the Inland Valley. A clean array can recover 5-15% of lost production, depending on the season and your specific trees. Learn more about our Solar Panel Cleaning in Claremont.

EV Charger Installation
We install Level 2 chargers for Claremont homeowners, including panel upgrades where the existing 100-amp service won’t support the added load. Most installations are done in a single day.

Solar Panel Maintenance & Monitoring
Gus monitors your system’s output and calls you when production dips below where it should be. You don’t have to watch the app. That’s our job.

Solar Panel Repair
Failed microinverters, damaged panels, tripped breakers, chewed wiring. We diagnose and fix it, and we carry a $40-off-any-repair-over-$200 standing offer.

Commercial Solar Installation
Flat-roof and small commercial systems for Claremont businesses along Foothill Boulevard, in the Village, and through the industrial pockets near Montclair. We handle the interconnection paperwork end to end.

Neighborhoods We Serve in Claremont
We work across all of Claremont, and typical response time for most service calls is same-day or next-day, depending on the issue. A few of the areas we regularly visit:
- The Village and the Craftsman blocks around it
- The foothill streets near the Claremont Wilderness Park
- The ranch neighborhoods south of Foothill Boulevard
- The areas around Claremont High School and Memorial Park
Why Claremont’s Climate & Housing Affect Solar
Claremont calls itself the City of Trees for good reason. Mature oaks, jacarandas, and spreading street trees shade whole roof planes in ways you won’t find in Pomona or Montclair. That’s not a dealbreaker for solar, but it changes the design math. On tree-covered lots, we usually spec microinverters or power optimizers so each panel produces independently. A single shaded panel won’t drag down the whole string. We also know the city’s tree preservation ordinance means you often can’t legally cut back a protected tree to improve production, so we design around the shade instead of fighting it.
Beyond the canopy, Claremont sits at about 1,100 feet at the foot of the San Gabriels. Summer heat is real, and AC demand is heavy. That means shorter payback periods than coastal customers see, because you’re offsetting expensive peak-hour usage. Up in the foothill streets near the Wilderness Park, we regularly see the north-side lots where the most sun-exposed roof face happens to be the one shaded by parkway trees the city planted and now protects. Ideal roof, shadiest yard. We model it accurately and tell you the honest expected output before you sign anything.
Housing stock matters too. A lot of Claremont’s pre-WWII Craftsman bungalows near the Village and the 1950s-70s ranches throughout the residential blocks still run on 100-amp electrical panels. A panel upgrade is often required before the utility will approve interconnection. We quote that work as part of the job so there’s no surprise line item later.
Pricing for Solar in Claremont
Here’s honest math for Claremont systems in 2026. A typical 6-8 kW residential installation in Claremont, installed by a direct crew with microinverters, runs roughly $17,000 to $26,000 before the federal tax credit. Battery storage typically adds $9,000 to $14,000 per unit, depending on brand and capacity. Panel cleaning in Claremont usually runs $150 to $300 per visit for a standard residential array. Service calls start at a flat diagnostic fee, but if you’re in our county, there’s no trip charge. And every quote is built off your actual SCE bill, not a brochure average. If a salesman needs an answer tonight, the answer is no. Bring us a bill, we’ll bring you the math.

FAQs About Solar in Claremont
In most cases, yes. With microinverters or power optimizers, each panel operates independently, so partial shade from Claremont’s oaks and jacarandas doesn’t tank the whole system. We’ll model your specific roof and show you honest expected production before you commit. Call (877) 550-6892 for a free site review.
A typical residential system in Claremont runs $17,000 to $26,000 before the federal tax credit, with battery storage adding $9,000 to $14,000. Your actual number depends on roof condition, panel count, and whether you need a 100-amp to 200-amp panel upgrade, which is common in Claremont’s older homes. Estimates are free.
Many of Claremont’s Craftsman and mid-century homes still carry 100-amp panels, and yes, PV interconnect usually requires upgrading to 200 amps. We include that in the quote upfront so there’s no surprise. Call for an exact assessment at no cost.
Most service calls in Claremont are scheduled same-day or next-day. A live person answers the phone 24/7, not a voicemail tree. Call (877) 550-6892 and Gus or a member of his crew will sort out what’s happening fast.
Depends on what failed. A bad microinverter or damaged panel is usually a simple, inexpensive repair. If the system is 15+ years old and multiple components are failing, replacement may be smarter. We’ll show you the numbers both ways and let you decide. No pressure. A free second opinion on any written estimate is always available.

What Claremont Customers Say
"Four different companies knocked on my door in one summer and every one of them wanted a signature that evening. Gus has a shop with his name on it, gave me the numbers on paper, and told me to take a fortnight and think about it."
- Winifred Castellano"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
