Solar Services in Rialto, CA

If your SCE bill has you checking the thermostat twice a month, you’re not alone. Rialto’s summer heat regularly pushes past 105°F, and those Time-of-Use peak charges hit hard between 4 and 9 p.m., exactly when your AC is working hardest. Gus’s Solar installs, repairs, and maintains residential solar across the 92376 and 92377 zip codes, and we answer the phone when you call. Not a call center. Not a ticket portal. A live person, day or night, at (877) 550-6892.

Why Rialto Homeowners Choose Gus’s Solar

Gus Petrakis started this company in 2011 and put his own name on the truck. That’s not a marketing slogan; it’s his actual last name on the door. When a Rialto homeowner calls about a system acting up, Gus is the one who answers or calls back. The crew that installs your panels is the same crew that comes back if something needs attention. We don’t hand work off to subcontractors, and we don’t disappear after the permit closes.

We’ve worked on homes in the Las Colinas area and throughout the neighborhoods off Riverside Avenue south of the 10. Homeowners there tend to have post-war tract homes with simple gable roofs, which is good for mounting, but many still carry original 60- or 100-amp panels. We plan for that upfront, not halfway through the permit process.

Every project carries the 90-Day Done Right Promise in writing. If it’s not right, Gus makes it right. One call brings him back.

Solar Services We Offer in Rialto

Solar Panel Installation

We design systems off your actual utility bill, not a brochure estimate. Bring us a bill, we’ll bring you the math, including what year 25 output actually looks like for a Rialto rooftop. Learn more about our Solar Panel Installation in Rialto.

Solar Panel Installation

Solar Battery Storage & Backup

With Time-of-Use rates punishing evening usage, a battery can shift your stored solar into the 4-9 p.m. window and keep your fridge and AC running during Public Safety Power Shutoff events. We size batteries to your actual load, using equipment from FranklinWH and Enphase. Learn more about Solar Battery Storage & Backup in Rialto.

Solar Panel Cleaning

Rialto’s warehouse and logistics truck traffic puts fine particulate matter on residential rooftops at a rate you won’t see in coastal cities. We recommend quarterly cleanings for most Rialto homes, not the annual schedule that works elsewhere in SCE territory. We flag soiling losses of 10-15% on systems that skip maintenance. Learn more about Solar Panel Cleaning in Rialto.

Solar Panel Cleaning

EV Charger Installation

If you’re buying an EV and already have solar, a Level 2 charger turns your daytime production into nighttime driving range. We handle the panel load calculation, the circuit install, and the charger itself, cleanly and to code.

Solar Panel Maintenance & Monitoring

We monitor your system so when production dips, we notice before you get the surprise bill. If a panel underperforms, we call you. You don’t have to chase us down.

Solar Panel Repair

Whether it’s a failed microinverter, a cracked panel from wind-blown debris, or wiring that a squirrel got into, we diagnose the issue and give you a straight answer on repair versus replace. No pressure. No upselling.

Why Rialto’s Climate & Housing Affect Solar

Rialto sits where the I-210 and I-10 logistics corridors meet, and that means two things for solar. First, the inland San Bernardino Valley delivers roughly 280 sunny days a year and some of the strongest solar irradiance in California, so your panels are going to produce. Second, summer temperatures regularly exceed 105°F, which causes panel temperature derating. The same heat that’s driving your AC load is also costing your panels 10-15% efficiency during peak hours. We size systems with that derating baked in, so your production estimate matches reality, not the day-one brochure number.

The housing stock adds another wrinkle. Rialto’s residential core is dominated by single-story post-war tract homes built between the 1950s and 1980s. Structurally, these gable and hip roofs are straightforward for mounting. Electrically, many still carry original 60- or 100-amp service panels, which means a panel upgrade often has to happen before your solar can be permitted and interconnected. That’s not an upsell. It’s just what the utility requires. Newer subdivisions on the city’s northern and western edges, built from the 1990s onward, typically have 200-amp service and concrete tile roofs that need tile-hook flashings, which adds some labor but nothing we haven’t done hundreds of times.

Pricing for Solar in Rialto

Let’s talk real numbers. A residential solar installation in Rialto typically ranges from $12,000 to $28,000 before federal tax credits, depending on system size, roof type, and whether a panel upgrade is needed. A 100-amp to 200-amp panel upgrade, when required, typically adds $2,500 to $4,500. Battery storage runs $8,000 to $16,000 depending on capacity and brand. Panel cleaning in Rialto typically runs $150 to $300 per visit, and the quarterly recommendation reflects the diesel particulate issue from all that I-10 and I-210 truck traffic. Solar panel repair work depends on the specific failure, but most residential fixes land between $200 and $700. We offer $40 off any repair over $200, a free second opinion on any written estimate, and no trip charge inside our own county. Seniors and veterans get a 10% discount that never expires.

What Rialto Customers Say

★★★★★ 4.8 from 10+ reviews

"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."

- Marguerite Ostrowski

"Told me straight that a battery did not make sense for how we use power and sold me the array without it. He talked himself out of a good deal of money that afternoon."

- Reginald Pontefract

"He flashed every roof penetration properly and showed me the flashing before it went down. Three roof seasons on and not a drop anywhere."

- Philomena Achara
