Solar Services in Lago Vista, TX
If you’re considering Solar Panel Installation - Lago Vista, you already know the math is different here. You’re on Pedernales Electric Cooperative, not Austin Energy, which means the rebate-driven solar pitch you may have heard from door-knockers doesn’t apply to your bill. That’s not a reason to skip solar. It’s a reason to work with someone who actually reads PEC rate schedules before quoting you a system size. Gus Petrakis has been doing exactly that since 2011, and he’ll tell you straight: bring us a bill, we’ll bring you the math. Call (877) 550-6892 and a live person answers.

Why Lago Vista Homeowners Choose Gus’s Solar
Gus puts his own name on the truck, on the building, and on every written estimate that leaves his desk. That’s rare in solar, and it matters more in a town like Lago Vista, where people still recognize each other at the hardware store. Homeowners in the Highland Lake Estates and Point Venture areas have had us on their roofs for years, and they’ll tell you the same thing: the price quoted is the price charged, the crew shows up in uniform and background-checked, and Gus is the one who answers when something isn’t right.
We’ve been a local shop since day one, with a published license number and a 90-Day Done Right Promise in writing on every job. If it’s not right, one call brings Gus back. No ticket portal, no call center, no subcontracted crew you’ve never met. Just Gus’s own people, doing the work the way they’d want it done on their own homes.
Solar Services We Offer in Lago Vista
Solar Panel Installation
A properly sized array on a Lago Vista rooftop can offset the bulk of your PEC bill, especially with the open hilltop exposure most lots enjoy. We quote year-25 output, not the day-one brochure number, so you know what the system will actually produce as it ages.
Learn more about our Solar Panel Installation in Lago Vista.

Solar Battery Storage & Backup
PEC’s buyback rates for excess energy are lower than retail net metering, which changes how you should think about storage. A battery sized for self-consumption means you use what you generate instead of selling it back at a discount. That’s why our Solar Battery Storage & Backup in Lago Vista is the smarter play, and we’ll show you the numbers on your own bill.

Solar Panel Cleaning
Lago Vista sits on exposed limestone ridges, and that means dust, pollen, and the occasional cedar bloom can settle on your panels faster than you’d expect. A layer of grime cuts into production silently, month after month. Our Solar Panel Cleaning in Lago Vista keeps your array earning its keep.

EV Charger Installation
Plenty of Lago Vista driveways now hold an EV, and charging at home makes sense when your solar array is already covering the house load. Our EV Charger Installation - Lago Vista wires level-2 chargers into your existing panel, cleanly and to code, with no drama and no surprise fees.

Solar Panel Maintenance & Monitoring
We don’t install a system and disappear. Gus monitors production so if a panel underperforms or a string drops out, you hear from us before you notice it on your bill. That’s what owner-operated means in practice.

Solar Panel Repair
Hail, wind, wildlife, or just years of Texas sun can take a toll. We repair what’s broken and tell you honestly when a repair isn’t worth the money, because a customer who trusts us is worth more than a service call.

Commercial Solar Installation
Lago Vista’s local businesses, churches, and community buildings face the same PEC rates as homeowners. A commercial array sized for daytime load can cut overhead meaningfully, and we handle the whole job with the same crew and the same promise.

Typical response time for a service call in Lago Vista is same-day or next-day depending on the issue. For a repair that’s affecting your power, we do our best to be there the same afternoon.
Why Lago Vista’s Climate & Housing Affect Solar
Lago Vista sits on exposed limestone ridges above Lake Travis, and that elevation gives your rooftop something most Austin-area homes don’t get: strong, relatively unobstructed sunlight with very little canopy shading. The native cedar and live oak scrub stays low here, so the sun hits your panels clean from mid-morning to late afternoon. That means slightly higher production than a tree-shaded lot in the city at the same latitude, and we factor that into your year-one estimate.
The flip side is the housing stock. Most homes here were built between the 1970s and 1990s as lakeside retreats and retirement spreads, which means single-story ranch and split-level homes on steep, rocky lots with wildly varied roof pitches. Some decking is original, and we inspect it before we install anything. And here’s a fact out-of-area crews often miss: the Edwards Plateau limestone under virtually every Lago Vista property makes ground-mount arrays cost-prohibitive without expensive rock drilling or blasting. Nearly every job here is rooftop-only, and if a sales rep tries to sell you a ground-mount, that’s your signal they don’t know this town.
Pricing for Solar in Lago Vista
We don’t do brochure estimates and we don’t do phone quotes that change at the door. Bring us a bill and we’ll build the math off your actual usage and PEC’s actual buyback rates. That’s the only honest way to size a system here.
- Solar panel installation (typical Lago Vista home): $14,000-$28,000 before incentives, depending on roof pitch, panel count, and equipment choice.
- Battery storage added to a system: $8,000-$16,000 depending on capacity and brand.
- Solar panel cleaning: $120-$250 per visit, depending on array size and roof access.
- EV charger installation: $600-$1,800 depending on panel capacity and conduit run.
- Solar panel repair: $40 off any repair over $200, and we honor a senior and veteran 10% discount that never expires.
Take two weeks. Think about it. The price will be the same.

FAQs About Solar in Lago Vista
No. Pedernales Electric Cooperative does not offer retail-rate net metering like Austin Energy’s program. PEC buys your excess energy back at a lower wholesale-adjacent rate, which means the financial case for solar in Lago Vista is built around self-consumption, not grid export. That changes how we size your system and whether a battery makes sense for you. Call (877) 550-6892 and we’ll walk you through it with your own bill in front of us.
Maybe. A lot of homes here were built in the 1980s and 1990s, and original decking can be tired. We inspect every roof before we quote anything, and if the decking isn’t sound, we’ll tell you what needs to happen first. No pressure, no rushed decision. If a salesman needs an answer tonight, the answer is no.
We don’t do same-day installs, and you shouldn’t want someone who does. A proper Lago Vista install includes a structural check, PEC interconnection paperwork, and careful roof flashing work. What we can do today is come look at your roof and your bill, and give you a written quote that won’t change. Estimates are free.
Yes, with a caveat. Panels lose a little efficiency in extreme heat, but Lago Vista’s elevation and open exposure usually mean strong production even in July and August. We factor Hill Country temperatures into your year-25 output estimate so the numbers reflect reality, not a lab test.
Depends on the panel age and the damage. If it’s a cracked panel from hail or a rock, replacement usually wins. If it’s a wiring or connector issue, repair is often the better call. We’ll give you both numbers honestly, and we offer a free second opinion on any written estimate you’ve received from another company. Call (877) 550-6892 and ask for Gus.

What Lago Vista Customers Say
"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"Honest quoting and good workmanship. He is not the cheapest quote I got, by some way, and he told me that himself and explained what the difference bought. I chose him anyway and I am glad."
- Alistair Fennimore"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
