Why Mendota Homeowners Choose Gus’s Solar
Gus Petrakis founded this company in 2011, and his name has been on the building ever since. That’s not a marketing line. It’s a fact you can verify, and it matters in Mendota, where plenty of folks have already sat through a high-pressure pitch from an out-of-state crew that quoted one number on the phone and another at the kitchen table. Gus runs this differently. Bring him a bill and he’ll bring you the math. The price quoted is the price charged, and no one here wants a signature tonight.
We’ve put systems on homes near the Mendota Pool and throughout the neighborhoods off Oller Street and Derrick Avenue. Those houses have character, and their electrical panels often show it. Our background-checked crew wears uniforms and arrives when we say they will. If something isn’t right after install, the 90-Day Done Right Promise means one call brings Gus back. That promise is in writing on every residential job.
Solar Services We Offer in Mendota
Solar Panel Installation
We design arrays around Mendota’s actual conditions: flat valley sun, hot summers, and dust that settles fast after a tractor pass. Every quote starts with your real utility usage so the system size matches what you actually consume, not what a template says.
Learn more about our solar panel installation in Mendota.

Solar Battery Storage & Backup
Mendota’s summer outages and peak-rate windows make Mendota Solar Battery Storage & Backup a practical choice, especially with Enphase and FranklinWH systems that keep your fridge and AC circuit running when the grid dips. We size storage to your actual evening load, not a generic package.

Solar Panel Cleaning
Panels east of town catch a tan film from field-tillage dust and cotton gin particulates. Our Mendota Solar Panel Cleaning schedule, matched to harvest timing and rain gaps, restores output that soiling quietly erodes between storms.

EV Charger Installation
We handle EV Charger Installation in Mendota, sizing Level 2 chargers to your panel’s remaining capacity, and we’re honest when an existing 100-amp service needs an upgrade first. No subcontracted crews. It’s Gus’s team on your wall.

Solar Panel Maintenance & Monitoring
Gus monitors system performance and calls you when output dips below what the array should produce. You don’t chase us. We flag it, schedule it, and fix it, often before you’ve noticed the issue on your own bill.

Solar Panel Repair
From failed microinverters to damaged racking after a windstorm, we diagnose the actual fault before quoting the repair. If another company gave you a written estimate, bring it to Gus for a free second opinion.

Commercial Solar Installation
Mendota’s packing sheds and processing facilities run hard during the harvest months, and a correctly sized commercial array cuts peak-demand charges meaningfully. Gus quotes the year-25 output, not the day-one brochure number.

Neighborhoods We Serve in Mendota
We cover all of 93640, with regular work in neighborhoods across Mendota. Typical response time for a no-trip-charge service call inside the county is same-day or next morning.

Why Mendota’s Climate & Housing Affect Solar
Mendota sits on the flat western San Joaquin Valley floor, surrounded by cantaloupe, cotton, and processing-tomato fields that generate airborne agricultural dust. That dust settles on south-facing panels between rainfalls and forms a tan film that cuts output more aggressively than what installers see in Fresno, 30 miles east. It’s common for us to spec a minimum 20 to 22 degree roof pitch or racking tilt in Mendota so runoff helps shed the film naturally, rather than defaulting to the low-slope racking common in urban installs.
Housing stock compounds the equation. Many Mendota homes are modest wood-frame or stucco builds from the 1950s through the 1980s, constructed for agricultural worker families. A significant share still runs on original 100-amp panels. Before a modern solar array can interconnect safely, that panel often needs a service upgrade, and a responsible quote accounts for that cost up front. We don’t hide it and discover it mid-install.
Pricing for Solar in Mendota
Residential solar in Mendota typically ranges from $12,000 to $22,000 before incentives, depending on system size, panel type, and whether a panel upgrade is required. Battery storage adds roughly $8,000 to $14,000 depending on capacity and brand. The honest variable is the electrical panel: homes with 100-amp service need an upgrade before interconnection, which runs $2,500 to $4,500 on average in this area. For Mendota specifically, many projects qualify for SASH or DAC-SASH assistance through the CPUC, which can substantially reduce out-of-pocket cost for income-qualified homeowners.
Gus quotes the year-25 output, not the day-one brochure number. Bring him a bill and he’ll bring you the math. If a salesman needs an answer tonight, the answer is no. Take two weeks. The price will be the same.

FAQs About Solar in Mendota
Most residential systems in Mendota fall between $12,000 and $22,000 before incentives, with panel upgrades adding $2,500 to $4,500 when needed. Income-qualified homeowners may reduce that significantly through SASH or DAC-SASH. Call (877) 550-6892 for an exact quote built from your actual utility bill.
Yes. Field-tillage particulates and cotton gin dust coat panels with a tan film between rains, and output can drop 10 to 25 percent depending on how long panels sit uncleaned. We spec tilt angles that help runoff self-clean and recommend a cleaning schedule tied to local harvest timing.
Often, but not always. Many 1950s to 1980s homes in Mendota still have original 100-amp service, and a modern array usually requires an upgrade to 200 amps before interconnection. We include that cost in the quote up front rather than surprising you later.
It will produce less. Dense tule fog between December and February can reduce generation to near zero for consecutive days. That reality belongs in your annual production estimate, and Gus quotes real year-25 numbers that account for it, not a sunny-day brochure figure.
We help qualifying homeowners structure projects around CPUC programs like SASH and DAC-SASH, which are designed for disadvantaged communities like Mendota. Rather than pushing a loan, we start with what your income and usage actually qualify for. Call (877) 550-6892 and we’ll walk through it.

What Mendota Customers Say
"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"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
