Gus’s Solar serves the 91310 and 91384 zip codes with a crew that knows Castaic’s terrain, its permitting quirks, and its roofs. Call (877) 550-6892 and you’ll get a live person, not a recording.

Why Castaic Homeowners Choose Gus’s Solar
Gus Petrakis puts his name on the truck and answers his own phone. That’s been the deal since he founded the company in 2011, and it hasn’t changed. Around Hasley Hills and Live Oak, homeowners tell us the same story: a national outfit quoted one number on the phone, then added $4,000 at the door and wanted a signature before they’d leave. Gus doesn’t work that way. He’ll sit at your kitchen table, look at your actual SCE bill, do the math in front of you, and tell you to take two weeks. The price won’t change if you do.
Beyond the straight numbers, Castaic homeowners stick with us because our crews are background-checked and uniformed, the same faces job to job. No subcontractors, no one you’ve never seen poking around your roof. And our 90-Day Done Right Promise guarantees it in writing: if something isn’t right, one call brings Gus back to make it right.
Solar Services We Offer in Castaic
Solar Panel Installation
A system sized off your real usage, not a brochure average. We handle Castaic’s concrete and clay tile roofs carefully with the right tile-hook hardware so you don’t end up with cracked tiles and leaks. Learn more about our Solar Panel Installation in Castaic.
Solar Battery Storage & Backup
Given where Castaic sits, a battery isn’t a luxury. Wildfire season means planned outages, and a battery keeps your fridge, well pump, or medical gear running while the grid is down. We install FranklinWH and other backup systems sized to what you actually need to keep on. Learn more about our Solar Battery Storage & Backup in Castaic.
Solar Panel Cleaning
Dust, ash from fire season, and bird droppings all cut into production. In Castaic’s dry months, a dirty array can lose 10-15% output. We recommend an annual cleaning, and we’ll check for cracked glass or loose connections while we’re up there. Learn more about our Solar Panel Cleaning in Castaic.
EV Charger Installation
If you’re driving an EV up and down the I-5 corridor, charging at home is cheaper than any fast-charge station. We install Level 2 chargers on dedicated circuits, and we’ll make sure your panel can handle the load before we start. Learn more about our EV charger installation in Castaic.
Solar Panel Maintenance & Monitoring
Gus doesn’t install a system and disappear. He monitors production remotely and calls you when output drops in a way that doesn’t match the weather. We handle inverter faults, panel degradation, wiring issues, and the routine checks that keep your system producing for decades. Learn more about our solar panel maintenance and monitoring in Castaic.
Solar Panel Repair
Storms, tree limbs, a bad microinverter, a cracked panel: things happen. We come out, diagnose the problem, and quote the fix before we touch anything. A system from any brand can be repaired; you don’t have to go back to the original installer. Learn more about our solar panel repair in Castaic.

Why Castaic’s Climate & Housing Affect Solar
Castaic sits in the I-5 corridor where the inland valley funnels toward Tejon Pass. Summer temperatures routinely blow past 105°F, and that specific heat matters for solar math. Panel output drops roughly 0.4-0.5% for every degree Celsius above 25°C, which is a technical way of saying your array won’t perform on a July afternoon the way the day-one brochure numbers suggest. A system sized on the winter average without a temperature derating factor will underproduce exactly when you need it most. We account for that. Your neighbors in the valley deal with heat, but not this particular intensity, and not with this particular soil and dust mix.
Then there’s housing stock. Most of Castaic’s residential homes are 1990s and 2000s tract builds, two-story stucco with concrete or clay tile roofs. Those roofs demand specialized tile-hook mounting hardware and a careful hand during install. Crack a tile and you’ve made a roof leak that costs more than the panel. The crews that came up doing composition shingle work in older cities don’t always know that. Ours do.

You won’t get a fake number from us. Here’s what Castaic homeowners typically see on solar work, all depending on roof condition, system size, and whether you add a battery:

FAQs About Solar in Castaic
Yes. Castaic is unincorporated LA County, not part of the City of Santa Clarita, so every solar permit routes through LA County Building & Safety, typically the Antelope Valley or Newhall district office. The process is slower and has different requirements than Santa Clarita’s city permitting. We handle the paperwork end to end.
Less than you might think. Most of Castaic’s residential parcels fall within California’s Very High Fire Hazard Severity Zone, which triggers a mandatory 36-inch setback from roof edges and ridges instead of the standard 18 inches. On a hip or multi-plane tile roof, that can shrink usable roof area significantly. We’ll measure it before we quote you, so the system we design actually fits.
Yes, and we do it regularly. Castaic’s housing stock is almost universally concrete or clay tile, which requires specialized tile-hook mounting hardware and careful installation to avoid cracking. This adds labor time and cost compared to composition shingle jobs, but it’s standard work for our crew.
Only if you have battery storage, yes. Without a battery, your system shuts off when the grid goes down, by design, so line workers don’t get electrocuted. Given Castaic’s wildfire-related outages, many homeowners pair panels with a battery. Call (877) 550-6892 and we’ll walk through whether it makes sense for your home.
Most of the time, repair is far cheaper than replacement. A failed microinverter, a wiring fault, or a cracked panel can usually be fixed for a few hundred to a few thousand dollars. We’ll tell you honestly if the system is too degraded to justify repair, but that’s rare. Call (877) 550-6892 for a straight answer, not a sales pitch.

What Castaic 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."
