Why Gilroy Homeowners Choose Gus’s Solar
We’re not a door-knocking crew. We don’t ask for a signature tonight, and we don’t hand your roof off to a subcontractor. Homeowners in Gilroy choose us because the math is transparent, the crew is background-checked and uniformed, and the owner answers his own phone. In neighborhoods like Glen Loma Ranch and the newer subdivisions off Santa Teresa Boulevard, we’ve built a reputation on showing up on time and doing what we said we’d do. The 90-Day Done Right Promise covers every job in writing: if it’s not right, Gus makes it right. One call brings him back.
We also know the difference between what a national outfit promises and what it delivers. If a salesman needs an answer tonight, the answer is no. Our position is simple: take two weeks, think about it, the price will be the same. That approach resonates with Gilroy homeowners who’ve already been burned once.
Solar Services We Offer in Gilroy
Solar Panel Installation
We design and install rooftop solar for Gilroy’s concrete-tile tract homes using tile-hook mounting systems that don’t compromise your roof. We quote the year-25 output, not the day-one brochure number. Learn more about our Solar Panel Installation in Gilroy.

Solar Battery Storage & Backup
With Gilroy’s summer AC loads and PG&E rate volatility, a battery bank changes the equation entirely. We install Enphase and FranklinWH systems sized to your actual overnight and peak-hour usage. Learn more about our Solar Battery Storage & Backup in Gilroy.

Solar Panel Cleaning
Gilroy’s dry inland summers mean dust and agricultural pollen settle on panels faster than coastal markets realize. A cleaning cycle twice a year keeps output where it should be. Learn more about our Solar Panel Cleaning in Gilroy.

EV Charger Installation
We install Level 2 home chargers on dedicated circuits, sized to your panel’s actual remaining capacity. If your panel is full, we’ll tell you before we sell you anything.

Solar Panel Maintenance & Monitoring
Gus’s crew monitors system performance and reaches out when production dips below expected levels. You won’t have to discover a failed inverter on your own.

Solar Panel Repair
Whether it’s a microinverter, a cracked panel, or wiring damaged by Gilroy’s summer heat, we diagnose and fix it. We offer $40 off any repair over $200 and a free second opinion on any written estimate.

Commercial Solar Installation
Gilroy’s agricultural processing facilities, including the cold-storage and drying operations clustered around Christopher Ranch, have massive summer electricity draws. We understand agri-commercial NEM tariffs and large ground-mount or carport installs.

Why Gilroy’s Climate & Housing Affect Solar
Gilroy sits at the sun-baked southern tip of the Santa Clara Valley, far enough inland that summer afternoons regularly hit 100°F or more with almost no marine-layer intrusion. That means more peak sun hours per day than San Jose or Santa Clara, and a heavier air-conditioning load than anywhere else in the county. We size systems for that combination – not with a generic calculator, but with your actual July and August usage from your PG&E bill. Bring me a bill, I’ll bring you the math.
Most of Gilroy’s housing stock is 1990s-2010s Spanish/Mediterranean tract construction with concrete tile roofs. Those roofs require tile-hook mounting and sometimes a structural load assessment before panels go up. We do that assessment as part of the quote, not as a surprise add-on later. The older wood-frame homes near downtown need different flashing and penetration details. Gus’s crew does the install themselves and flashes every roof penetration properly. That’s not a detail we subcontract out.

FAQs About Solar in Gilroy
Most Gilroy residential systems fall between $15,000 and $24,000 before the federal tax credit, with the final number driven by your roof type, system size, and whether you add battery storage. Call (877) 550-6892 and we’ll build an exact quote off your PG&E bill.
Yes, and that’s most of what we do in Gilroy. Tile-hook mounting systems are the standard for the 1990s-2010s tract homes that dominate the city’s housing stock, and we’ll include any structural load assessment in the quote. Learn more about our Solar Panel Installation in Gilroy.
Not always, but with Gilroy’s heavy summer AC loads and PG&E’s peak-hour rates, a battery often shortens your payback period more than panels alone. We’ll run the numbers both ways using your actual bill. Learn more about our Solar Battery Storage & Backup in Gilroy.
Twice a year is the starting point for most Gilroy homes, given the inland dust, agricultural pollen, and dry summer conditions. If you’re near active farmland or a construction area, you may want three visits. Learn more about our Solar Panel Cleaning in Gilroy.
We answer the phone 24/7 and can often be there same-day for urgent repair situations. For a free estimate, we’ll work around your schedule, not the other way around. Call (877) 550-6892 and a live person picks up.

What Gilroy Customers Say
"Panel level monitoring so I can see each one, proper stainless clips under the array rather than zip ties, and he walked me under it with a torch to show me before he signed off."
- Cassius Delacroix"Gus's own crew did the install. Not a subcontractor who had never met him, which is what the big outfit quoted me and could not tell me who would actually be on my roof."
- Aurelia Santibanez"He modelled it on my actual bill and the current export rates rather than the old ones, and told me plainly that the payback was longer than the door knockers had claimed. Then it came in about where he said it would."
- Octavius Redmond
