Solar Services in Altadena, CA
Solar in Altadena runs on a different set of rules than the rest of the San Gabriel Valley, and most of it comes down to one fact: Altadena is unincorporated Los Angeles County. That means your permits go through LA County Building and Safety, your inspections are done by LADBS, and your system has to meet fire-zone setback rules that contractors working Pasadena jobs sometimes never see. We know the County’s Title 24 solar checklist and the fire-zone documentation they want before your first plan check. If you’re thinking about panels, batteries, or a repair in Altadena, call Gus at (877) 550-6892 and we’ll walk you through what your specific property actually needs.

Why Altadena Homeowners Choose Gus’s Solar
Gus Petrakis founded this company in 2011 and he’s never hidden behind a call center. The name on the truck is the name on the building, and the phone number rings through to a live person, day or night. That matters when you’re the one waiting on LADBS plan-check corrections and you need a straight answer, not a ticket number.
We work regularly in the neighborhoods north of Altadena Drive and throughout the flats around Lake Avenue and Fair Oaks. Homeowners in The Meadows and along the Christmas Tree Lane corridor have had us on their roofs, and Gus’s crew has done panel installs, battery backups, and repairs across the 91001 and 91003 zip codes. The 90-Day Done Right Promise covers every job in writing: if it’s not right, Gus makes it right, and one call brings him back. Our technicians are background-checked, uniformed, and they’re our own crew, not a sub we handed the work off to. The price we quote is the price you pay, and we’ll tell you to take two weeks before you sign anything. If a salesman needs an answer tonight, the answer is no.
Solar Services We Offer in Altadena
Solar Panel Installation
We design systems around your actual roof, your actual usage, and Altadena’s specific fire-zone requirements. No two hillside properties here lay out the same way, and we don’t pretend otherwise. Learn more about our Solar Panel Installation in Altadena.

Solar Battery Storage & Backup
With Altadena’s fire-risk profile and the public safety power shutoffs that come with it, battery backup isn’t a luxury here. We install and configure systems that keep your lights on when the grid goes down. Learn more about our Solar Battery Storage & Backup in Altadena.

Solar Panel Cleaning
Ash, dust, and the foothill air here leave a film on panels that cuts into output faster than most homeowners realize. We clean arrays by hand, carefully, without scratching the glass or voiding your warranty. Learn more about our Solar Panel Cleaning in Altadena.

EV Charger Installation
From a simple Level 2 charger in your garage to load-managed setups on older 100-amp panels, we’ll wire it correctly and get it permitted. Altadena’s older homes often need panel work first, and we’ll tell you that before we quote, not after.

Solar Panel Maintenance & Monitoring
Gus monitors systems and calls you when something’s off. You don’t have to notice the production dip; that’s our job. Annual checkups catch what the app can’t.

Solar Panel Repair
A cracked panel, a failed inverter, a chewed wire. We diagnose it, quote it honestly, and fix it. $40 off any repair over $200, and no trip charge inside Los Angeles County.

Commercial Solar Installation
For storefronts, offices, and warehouses across Altadena, we handle the design, the LADBS paperwork, and the installation with the same no-nonsense approach we bring to residential work.

Neighborhoods We Serve in Altadena
We work all over Altadena, from the flats south of Washington Boulevard up into the hillside streets near the Cobb Estate. Typical response time for most calls is same-day or next-day, depending on the job.

Why Altadena’s Climate & Housing Affect Solar
Altadena sits at roughly 900 to 2,000 feet on the San Gabriel foothills, above the marine layer that dulls sunlight over the LA basin. That elevation means more peak sun hours and more production per panel, but it also means north-facing roof planes point straight into the mountains and are essentially dead for solar. A proper site assessment here has to study orientation carefully, not just glance at a satellite photo.
Then there’s the housing stock. Much of Altadena was built between the 1920s and 1950s: Craftsman bungalows, Spanish Colonial Revival homes, and post-war ranches. Many still run on original 100-amp or sub-100-amp panels, which almost always need a service upgrade before the utility will approve interconnection. Hillside custom homes add multi-pitch roofs and partial shade from mature oaks and eucalyptus, complicating both layout and structural attachment. A contractor who treats Altadena like flat Pasadena is going to miss something, and you’re the one who pays for the correction.
Pricing for Solar in Altadena
Bring us a bill, and we’ll bring you the math. That’s the whole approach: we work off your real usage and your real utility rate, not a brochure estimate. Here’s what to expect in the current Altadena market:

FAQs About Solar in Altadena
Yes, and because Altadena is unincorporated LA County, permits go through LA County Building and Safety, not a city building department. The County has its own Title 24 solar checklist and fire-zone documentation requirements, and missing one detail can delay your project by weeks. Call (877) 550-6892 if you want help navigating the LADBS process.
Altadena is mapped as a Very High Fire Hazard Severity Zone, so every installation must meet California Fire Code setback rules: 18-inch ridge setbacks, 36-inch access pathways, and Class A fire-rated modules. Some contractors working the basin cities don’t account for these, and it causes failed inspections. We build them into the design from day one.
Most single-panel failures are cheaper to repair or replace individually than to overhaul the whole array. A failed inverter or a cracked panel usually runs a few hundred dollars to fix. If your system is old and underperforming across the board, replacement may make more sense. Call us and we’ll tell you straight, with no push toward the more expensive option.
Most calls in Altadena get same-day or next-day service. For emergencies like a downed wire or a sparking inverter, call (877) 550-6892 anytime: a live person answers, not a voicemail, 24/7.
Many Altadena homes still have original 100-amp or sub-100-amp panels from the 1920s through 1950s build era, and those almost always need a service upgrade before solar can be interconnected. We’ll check your panel and tell you upfront, before you spend a dollar on panels that can’t be connected.
Have a question we didn’t answer? Call (877) 550-6892. Gus answers his own phone, and he’ll give you a straight answer without a sales pitch.

What Altadena Customers Say
"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"Production dropped one spring and I did not even notice. Gus rang me, because he watches the monitoring, and had it sorted the same week."
- Sunita Balakrishnan
