Why Fontana Homeowners Choose Gus’s Solar
Fontana has been hit hard by out-of-state solar companies that quote one number on the phone and another at the door. That’s not how we operate. Gus publishes his name, his license number, and his address. When we quote a price, it’s the price you pay. We tell every Fontana homeowner the same thing: take two weeks, think about it, the price will be the same. If a salesman needs an answer tonight, the answer is no.
We’ve done work across North Fontana’s master-planned communities in 92336 and the older flatland tracts down in 92335. Homeowners in neighborhoods like Sierra Lakes, Hunter’s Ridge, and the Southridge area call us because they’ve seen the difference between a local crew and a pop-up sales operation. We show up on time, we flash every roof penetration properly, and if something’s not right within 90 days, Gus comes back and makes it right, in writing. That’s the 90-Day Done Right Promise, and it’s on every job we do in Fontana.

Learn more about our Solar Battery Storage & Backup in Fontana.
Solar Panel Cleaning
Dust from the Mojave settles against the San Gabriel mountain wall and coats Fontana panels faster than almost anywhere in the Inland Empire. We recommend Fontana Solar Panel Cleaning here, and our crews do it safely without damaging your array.

EV Charger Installation
Our EV Charger Installation - Fontana service includes Level 2 chargers in garages, plus panel upgrades when your existing service can’t handle the added load. Many 1950s-era Fontana homes need that upgrade, and we’ll tell you honestly if yours does.

Why Fontana’s Climate & Housing Affect Solar
Fontana sits hard against the San Gabriel mountain wall, and that geography shapes every system we design here. The mountains trap smog and Mojave-origin dust, which settles on panels far more aggressively than in Ontario or Rancho Cucamonga. Without regular cleaning, that soiling can cut panel output 8 to 15 percent. At the same time, Fontana’s inland thermal trough pushes summer highs to 105 or even 112 degrees during peak afternoon hours. Panels lose efficiency as they heat up, so a system sized using coastal SCE assumptions will underproduce here. We bake both factors into every production model we quote in Fontana.
The housing stock matters too. North Fontana’s large master-planned homes in 92336 were mostly built between the late 1990s and mid-2000s with Spanish S-tile or flat concrete-tile roofs. Those require specialized standoff flashing and add real labor cost compared to asphalt shingle work. Meanwhile, the older flatland neighborhoods in 92335 and 92334 are full of 1950s-to-1970s tract homes with smaller roof footprints and 100-amp service panels. Fontana Building & Safety frequently flags those panels as insufficient for interconnection, which means a $2,500 to $4,000 panel upgrade before your system goes live. Out-of-area sales reps who quote remotely without pulling permit history miss this line item constantly. Gus pulls the permit history before he gives you a number.

FAQs About Solar in Fontana
Most Fontana systems run $14,000 to $28,000 before the federal tax credit, but the real number depends on your roof type, panel count, and whether your service panel needs upgrading. North Fontana S-tile roofs add labor cost. Older flatland homes often need a 100-amp to 200-amp panel upgrade, which runs $2,500 to $4,000. Call (877) 550-6892 and bring us a bill for an exact quote.
Yes. Fontana regularly hits 105 to 112 degrees in summer, and panel efficiency drops as temperature climbs above standard test conditions. That thermal derating means a system sized for coastal SCE territory will underproduce here. We model your production with Fontana’s actual temperature data, not a generic California average.
Annually at minimum. The mountain wall traps Mojave dust and smog, and we’ve measured soiling losses of 8 to 15 percent on unwashed Fontana arrays. That’s real money off your annual production. We offer cleaning contracts that keep your panels performing.
Many older Fontana homes in 92335 and 92334 do. Fontana Building & Safety commonly flags 100-amp service panels as insufficient for grid-tied interconnection, adding $2,500 to $4,000 to the project. We pull permit history before quoting so you’re not surprised mid-project. It’s cheaper to know upfront than after the crew starts.
Usually, yes. Calls are answered by a live person 24/7, and our Fontana response time for service calls is typically same-day or next morning. There’s no trip charge inside the county. Call (877) 550-6892 and we’ll get someone there.

What Fontana 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
