AfterSolar Services in Lakeway, TX
Solar panel installation in Lakeway comes with more moving parts than most companies let on. You’re in PEC territory, not Austin Energy, which changes the math on what you’ll actually save. Most of the homes here are big, custom builds with rooflines that don’t lend themselves to a standard panel layout. If you call us at (877) 550-6892, you’ll get Gus or someone on his crew who knows the difference before they ever climb on your roof. We serve all of 78738, and we’ll give you straight numbers based on your actual bill, not a glossy brochure estimate.

Why Lakeway Homeowners Choose Gus’s Solar
Gus Petrakis puts his own name on the truck. He’s been doing this since 2011, runs the company himself, and still answers his own phone. When you hire Gus’s Solar, you’re not getting a rotating cast of subcontractors or a sales rep who hands your job off to an anonymous crew. You get Gus’s own background-checked, uniformed team, and Gus is the one who shows up if something isn’t right.
That matters in a place like Lakeway, where word travels fast. We’ve installed and serviced systems in Rough Hollow and Serene Hills, two of the neighborhoods where HOA design review boards are known to be particular about what goes on a roof. We handle the approval paperwork because we know these communities and what their boards want to see. A live person answers our phone 24/7, so when a Lakeway homeowner has a question on a Saturday morning, they’re not sitting through a voicemail tree.
Solar Services We Offer in Lakeway
Solar Panel Installation
We design systems around Lakeway’s actual roof conditions: hipped and gabled rooflines, metal and tile surfaces, cedar and live oak shade. No two Lakeway homes are the same, and we don’t pretend otherwise.
Learn more about our Solar Panel Installation in Lakeway.
Solar Battery Storage & Backup
With PEC’s excess-generation buyback rate running lower than what Austin Energy customers get, Lakeway solar battery storage & backup often makes the difference between a system that pays off and one that leaves money on the table at true-up. We’ll show you the year-25 numbers both ways.

Solar Panel Cleaning
The limestone dust and pollen up here settle on panels faster than people expect, and a dirty array can lose 5-15% of its output without regular Lakeway solar panel cleaning. We do maintenance cleaning on a schedule that makes sense for your specific lot, not a generic quarterly plan.

EV Charger Installation
Big homes with big garages often need EV charger installation in Lakeway done properly, and we do that work alongside solar so the whole electrical picture stays coherent. You plug in at night on power you made during the day.
Solar Panel Maintenance & Monitoring
Gus monitors systems and calls you when something looks off, instead of waiting for you to call him. That’s a different standard than what the out-of-state companies offer after install day.
Solar Panel Repair
If your existing system is underperforming or has stopped reporting, we’ll diagnose it and fix it. We also offer a free second opinion on any written estimate for repair work, no pressure attached.
Commercial Solar Installation
For small commercial properties around Lakeway, we handle design, PEC interconnection, and installation with the same owner-accountable approach we use on homes.
Neighborhoods We Serve in Lakeway
Our crews are in and around 78738 every week. Typical response time for a service call in Lakeway is same-day or next-day, depending on the job. These are the areas where we’re most often working:
- Rough Hollow - HOA design review, multi-plane rooflines, and homes built into the hillside
- Serene Hills - newer custom construction with steep pitches and tile roofing
- The Hills of Lakeway - golf-adjacent lots with mature canopy shade
- Lakeway Highlands - a mix of original resort-era homes and newer builds
- Flintrock Falls - luxury homes where backup power is a common request
Why Lakeway’s Climate & Housing Affect Solar
Lakeway sits west of Austin on the edge of the Hill Country, and that position works for and against solar in specific ways. On the plus side, you’re getting some of the strongest solar irradiance in Texas, with less urban haze than points east. On the other hand, this is limestone ridge-and-canyon terrain, not flat suburban lots. An east-facing slope that looks perfect for a patio can lose serious morning production, while a west-facing hillside home might actually overproduce in the afternoons when the grid is stressed. That’s why we model every Lakeway system per-parcel using your actual roof geometry and shade profile, not a city-wide average.
Then there’s the housing stock itself. Most homes in 78738 are post-2000 custom builds in the 3,500-6,000+ square foot range, and many sit on lots carved into limestone with hipped, multi-gabled, or steeply pitched metal and tile roofs. Those rooflines don’t offer long, contiguous south-facing runs the way a suburban tract home does. The older resort-era homes from the 1970s and 80s have simpler pitches, but they’re often shaded by mature cedar and live oak. Both types of properties need a designer who actually looks at the roof before quoting a system size.
Pricing for Solar in Lakeway
We quote off your actual utility bill and your actual roof. Here’s what you’re looking at after the federal tax credit, for a typical Lakeway home:

- System with battery backup (10-14 kWh): $34,000-$52,000 before credits; $23,800-$36,400 after the federal credit
- Panel cleaning (single visit): $180-$350 depending on roof access and array size
- EV charger installation: $700-$1,800 depending on panel capacity and run length
- Repair diagnostics: $40 off any repair over $200, and a free second opinion on any written estimate
Bring us a bill, we’ll bring you the math. We don’t need an answer tonight. Take two weeks. The price will be the same. If a salesman needs an answer tonight, the answer is no. We also offer a senior and veteran discount of 10% that never expires.

FAQs About Solar in Lakeway
PEC’s interconnection queue routinely moves slower than Austin Energy’s, and the cooperative’s excess-generation buyback rate has historically sat below AE’s Value of Solar tariff. That means Lakeway homeowners who skip battery storage and assume Austin-style economics can get caught at true-up. We know PEC’s current tariff structure and pre-stage applications early. Call (877) 550-6892 and we’ll explain what it means for your bill.
Yes. Most of Lakeway’s newer custom homes use tile or standing-seam metal, and both require a different mounting approach than composition shingle. Gus’s crew does the install themselves and flashes every roof penetration properly. We do not hand the work off to a sub.
HOAs in Lakeway typically require design review approval before any visible roof equipment goes up. The process varies by community, and some boards want specific panel layouts or color-matched racking. We prepare the application package and handle the back-and-forth, because we’ve been through these specific boards before.
It depends on the age of the system and what failed. If a string inverter from the early 2010s died, replacement often makes more sense than repair, especially now that battery-ready hardware from brands like Enphase and SolarEdge is common. If a panel underperforms, repair is usually the better call. Bring us your last bill and we’ll cost out both paths. Estimates are free.
In most cases, yes. Our crews are in the 78738 area weekly, and a live person answers the phone 24/7. Call (877) 550-6892 and we’ll tell you straight what we can do and when.

What Lakeway 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
