Why Whittier Homeowners Choose Gus’s Solar
Whittier is a city where people still ask who their neighbors use before they hire anyone. That works in our favor. Gus Petrakis founded this company in 2011, and he’s never hidden behind a LLC name or a sales team. When you call, you get Gus or a member of his own crew. When something goes wrong, one phone call brings him back. We work throughout Friendly Hills, the Uptown area, East Whittier, and the flatland tracts south of Whittier Boulevard, and we’ve built a strong local reputation doing it. Every job is backed by our 90-Day Done Right Promise in writing, and a live person answers the phone 24/7. No after-hours voicemail, no ticket queue. Crew members are background-checked, uniformed, and they work for Gus directly. That’s the difference between a company whose name is on the building and a pop-up sales crew that’s gone by spring.
Solar Services We Offer in Whittier
Solar Panel Installation
We design rooftop systems around your actual roof pitch, orientation, and the shading conditions specific to your street. Flatland Ranch homes and hillside Craftsman bungalows need very different approaches, and we quote both accordingly. No brochure math. Gus’s team pulls shading reports and uses your real utility usage before we recommend a single panel.

Solar Battery Storage & Backup
With SCE’s time-of-use rates and the periodic heat-wave flex alerts, Whittier Solar Battery Storage & Backup changes the math considerably. We install Enphase, Tesla, and FranklinWH storage systems sized to actually cover your evening loads, not just check a box. You’ll know what backup wattage you’re getting on day one.

Solar Panel Cleaning
Whittier’s position at the base of the Puente Hills means freeway particulate from the 605 and 60 interchange settles on panels faster than in cleaner-air parts of the county. Whittier Solar Panel Cleaning measurably recovers production here. We do it properly with soft brushes and filtered water, not a pressure washer.

EV Charger Installation
Whether you drive a Tesla, a Chevy Bolt, or anything else, we handle EV Charger Installation - Whittier with the circuit sizing and panel capacity checks done right. In many Whittier ranch homes, that means evaluating whether your 100-amp service can handle the extra load, and we’ll tell you honestly if it can’t.
Solar Panel Maintenance & Monitoring
If your system was installed by someone who no longer answers the phone, we take over monitoring and maintenance. Gus watches production numbers and calls you when something dips, not the other way around. You shouldn’t have to discover a failed string by opening a surprise utility bill.
Solar Panel Repair
Failed inverters, animal damage, faulty optimizers, roof leaks around flashed penetrations. We diagnose it, quote it plainly, and fix it with the same care as an original install. If a salesman needs an answer tonight, the answer is no. We quote the year-25 output, not the day-one brochure number.
Commercial Solar Installation
Warehouses and office buildings in Whittier’s industrial corridors face different interconnection rules and different rate structures. We design around demand charges and peak-shaving opportunities, and we handle the SCE paperwork end to end. Gus quotes the system that makes sense on paper, not the one that makes the biggest commission.
Neighborhoods We Serve in Whittier
Our crews are in Whittier every week, and typical response time for a service call or estimate visit is same day or next day. The parts of town we work in most often:
- Friendly Hills
- Uptown Whittier

Why Whittier’s Climate & Housing Affect Solar
The Puente Hills physically cut Whittier in two, and that split changes what a good solar design looks like. Hillside neighborhoods like Friendly Hills deal with steep, multi-plane roofs, mature eucalyptus and oak canopy, and north-facing exposures that can cut annual irradiance by 15 to 20 percent compared to a flat lot a mile south on Whittier Boulevard. If a company quotes you without pulling a shading report, they’re guessing. Flatland East Whittier is a different problem entirely: those post-WWII ranch homes built between 1950 and 1975 almost universally still run on original 100-amp electrical panels with aluminum branch wiring. Before SCE will approve interconnection, most of them need a panel upgrade to 200 amps. That’s a real line item, and any honest Whittier solar quote includes it upfront. The good news here is the climate: Whittier sits far enough inland that it largely escapes the coastal marine layer that cuts peak sun hours in Long Beach or Downey. You get real, usable production here. The panels just get dirtier from the 605 and 60 interchange particulate, so annual cleaning actually moves the needle on output.
Pricing for Solar in Whittier
Keep in mind that a solar price without knowing your roof or your bill is a guess, and we don’t do guesses. Here are honest starting ranges for Whittier:
- Residential solar installation: $14,000-$28,000 before incentives, depending on system size and roof pitch
- Battery storage addition: $10,000-$18,000 for most single-battery systems
- Panel cleaning: $199-$450 depending on array size and roof access
- EV charger install: $700-$1,800 depending on circuit length and panel capacity
- Electrical panel upgrade (100A to 200A): $3,200-$5,500 when bundled with solar

FAQs About Solar in Whittier
Most Whittier homes fall between $14,000 and $28,000 before federal incentives, with the biggest variables being roof pitch, panel count, and whether your electrical panel needs upgrading. Flatland ranch homes on original 100-amp service should expect the panel upgrade line item on almost every quote. Call (877) 550-6892 and bring your SCE bill, we’ll give you a real number, not a range.
If your home in the 90604, 90605, or 90606 ZIP codes was built between 1950 and 1975 and still has its original electrical panel, the answer is almost certainly yes. SCE will not approve interconnection on most of these without a 200-amp upgrade. Gus’s crew does the upgrade and the solar install together, so the timeline is shorter and the inspection is cleaner.
No. Same-day installation is not a thing for a quality solar job. Permitting, design approval, and SCE interconnection paperwork take time. What we can do same day is come out, inspect your roof and your panel, and give you a written quote. If someone promises you panels on your roof tomorrow, walk away.
Whittier gets strong inland sunshine without the marine layer that drags down coastal production, which makes it a genuinely good solar market. The tradeoff is particulate buildup from the 605 and 60 interchange, which settles on panels and cuts output faster than in cleaner-air suburbs. Annual cleaning is a real production factor here, not optional maintenance.
Yes, estimates are free and there is no pressure to decide. Take two weeks. Think about it. The price will be the same. If you have a written estimate from another company, we’ll give you a free second opinion on it too. Call (877) 550-6892 or visit our home page to learn more.

What Whittier Customers Say
"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"My previous solar company went out of business and left me with an array nobody would touch. Gus took the system over, replaced two dead microinverters, and it has run properly since."
- Ferdinand Kaltenbrunner"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
