Why Moraga Homeowners Choose Gus’s Solar
Moraga is the kind of town where people ask their neighbors who did their roof, their windows, their solar. Gus Petrakis started this company in 2011 and has been answering his own phone since day one. When we install on a street in the Rheem Valley or up in Sanders Ranch, that work carries his name. The number on the truck is his cell. Homeowners in Moraga choose us because we do not push for a signature tonight, and we show up when we say we will.
We serve the whole Moraga area: the neighborhoods off Moraga Way, the homes tucked into the hills above St. Mary’s College, the older ranches down near the Commons. Our techs are background-checked and uniformed, and they’re the same crew that handles installs across the 94556, 94570, and 94575 ZIP codes. The 90-Day Done Right Promise backs every job in writing. If something isn’t right, Gus comes back and makes it right. One call does it.
Solar Services We Offer in Moraga
Solar Panel Installation
We design and install rooftop solar systems sized off your actual PG&E usage, not a brochure estimate. Moraga’s sloped hillside lots often have fragmented roof planes, so we do a careful pre-site shading analysis before laying out a single panel. Learn more about our Solar Panel Installation in Moraga.
Solar Battery Storage & Backup
Summer valley heat pushes Moraga AC loads high in the late afternoon, exactly when PG&E’s time-of-use rates peak. A battery shifts your stored solar into those expensive hours and keeps your fridge and lights running during fire-season shutoffs. Learn more about our Solar Battery Storage & Backup in Moraga.
Solar Panel Cleaning
Moraga’s dry summers leave a fine dust film on panels, and valley oak pollen in spring cuts output more than most people realize. We clean systems safely, without scratching the glass or voiding your warranty. Learn more about our Solar Panel Cleaning in Moraga.
EV Charger Installation
We install Level 2 chargers in garages and on exterior walls, including panel upgrades when your electrical service can’t handle the extra load. Many Moraga homes built in the 1960s and 1970s have 100-amp panels that need a bump before a charger goes in.
Solar Panel Maintenance & Monitoring
We monitor systems daily and call you when production drops, rather than waiting for you to notice a high bill. If a panel or inverter underperforms, we know before you do.
Solar Panel Repair
Failed inverters, damaged wiring, cracked panels, roof leaks around mounts. We diagnose and fix systems other companies installed, not just our own. A live person answers the phone 24/7 when something fails.
Commercial Solar Installation
For businesses and multi-unit properties in Moraga, we design commercial arrays that cut operating costs and work around existing roof equipment and parking layouts.
Neighborhoods We Serve in Moraga
Our trucks are in Moraga most weeks, and when you call, we can typically have someone out to your property within a day or two depending on the job. Typical response for estimates runs under 48 hours; repairs get prioritized.

Why Moraga’s Climate & Housing Affect Solar
Moraga sits in a protected inland valley behind the East Bay ridgeline. The marine fog that smothers Oakland and Berkeley most mornings burns off before it reaches you, which means Moraga gets measurably more annual sun hours than cities eight to ten miles west. That sounds great for solar, and it is, but there’s a catch: this same valley trap pushes summer afternoon temperatures to 95°F and above, far hotter than what Lafayette or Orinda see. Your air conditioner runs hard from 4 p.m. to 9 p.m., exactly the window when PG&E’s time-of-use rates under NEM 3.0 are highest. That makes battery storage in Moraga not just a backup luxury but a financial tool for load shifting.
Winter is the flip side. Temperature inversions settle cold fog into the valley floor for days at a stretch, so December and January production dips lower than the sun-hour average would suggest. Anyone quoting you a Moraga system using a generic Bay Area number is missing the seasonal spread. We build the year-25 output estimate from your actual bill history and Moraga’s real weather patterns, not a regional average.
Why Moraga’s Rooflines & Trees Change the Design
Moraga developed mostly in the 1960s through 1980s, with custom and semi-custom homes on sloped hillside lots. That means varied roof planes, steep pitches, and chimneys that break up usable space. South-facing sections are often excellent, but north-facing rear rooflines can be nearly useless for production. We walk every roof before we quote, and we flag what won’t work rather than cramming panels onto a shaded slope to make the system look bigger.
Then there are the oaks. Lots backing up to Las Trampas Creek and the open-space corridors around Moraga Commons carry mature valley oaks with canopies that throw moving shadows across the roof through the day. Standard string inverters handle those shifting shade patterns badly; one shaded panel drags down the whole string. On these canyon-lot homes, we consistently spec microinverters or DC optimizers, like those from Enphase or SolarEdge, so each panel works independently. It costs a bit more on day one, but the year-25 output difference on a partially shaded Moraga roof is significant. Bringing Gus a year of PG&E bills and letting him map the shade is the fastest way to a quote that actually holds up.
Pricing for Solar in Moraga
Here’s what Moraga homeowners can expect, based on jobs we’ve completed in the area. These are ballpark figures; your roof, your electrical panel, and your usage history will move the number.
- Solar panel installation (typical 5-8 kW Moraga home): $14,000-$24,000 before tax credits
- Battery storage (single battery, installed): $9,000-$15,000 depending on brand and capacity
- Panel cleaning (full residential system): $180-$350 per visit
- EV charger installation: $800-$2,500 depending on panel capacity and wiring distance
- Inverter replacement: $2,000-$4,500 depending on system size and inverter type
- Repair diagnostics: $99 service call, waived if we do the repair
Bring us a bill, we’ll bring you the math. The price quoted is the price charged, and we don’t need an answer tonight. Take two weeks, think about it, the number will be the same. And we still run the standing deals: $40 off any repair over $200, a free second opinion on any written estimate, no trip charge inside the county, and a Senior and Veteran discount of 10% that never expires.

FAQs About Solar in Moraga
Most Moraga homes fall between $14,000 and $24,000 before the federal tax credit, depending on roof complexity, shading, and panel count. Hillside lots with steep pitches and fragmented roof planes push toward the higher end. Call (877) 550-6892 for an exact quote built from your actual bill; estimates are free and there’s no trip charge inside the county.
Yes, but the math changed in 2023: exported solar credits are worth far less than they were, so systems need to be sized for self-consumption and, in most cases, paired with battery storage. Moraga’s hot summer afternoons mean high on-site demand exactly when rates peak, which actually improves the paired solar-plus-battery case compared to coastal communities. We’ll run your last 12 months of usage and show you the year-25 numbers before you decide.
Not if it’s designed correctly. The mature oaks along Las Trampas Creek and around Moraga Commons create moving shade that standard string inverters handle poorly. We spec microinverters or DC optimizers on these lots, so a shaded panel doesn’t drag the whole system down. We’ll do a full shade analysis before quoting, and if a tree makes half your roof unusable, we’ll tell you plainly rather than overselling a system that underperforms.
Yes, our crew has experience on the steep pitches and varied rooflines common to 1960s-1980s Moraga hillside construction. Safety is the first concern on these jobs: we use proper fall protection and flash every roof penetration correctly. We will not rush a steep-roof install, and the 90-Day Done Right Promise applies in writing to every job we do in Moraga.
Estimates are typically scheduled within 48 hours, and repairs get prioritized because a failed inverter means lost production every day. A live person answers the phone 24/7 at (877) 550-6892, so if you call on a Sunday night because your system is down, you’ll talk to a person who can schedule the fix, not a voicemail.

What Moraga 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
