Fast, Reliable Solar Panel Installation Across Lakeway
A rooftop solar system on a typical Lakeway home runs $28,000 to $52,000 before federal tax credits, and most installs take two to four days once PEC approves the interconnection application. That application is the part out-of-town installers get wrong here. Gus’s Solar has worked inside Pedernales Electric Cooperative territory long enough to pre-stage paperwork before the first panel goes up, so your system isn’t sitting finished on the roof while you wait on a queue. If you want straight numbers off your actual utility bill and a crew that shows up when they say they will, call (877) 550-6892.
Why Gus’s Solar Is Lakeway’s Preferred Solar Panel Installation Company
Lakeway is not Austin. The homes are bigger, the rooflines are more complex, and the utility runs on different rules than anything inside Austin Energy’s service area. We have worked on custom builds in Rough Hollow, Serene Hills, and The Hills long enough to know which HOA design-review boards ask for line-of-sight studies and which ones reject panels on street-facing planes outright. That local knowledge saves you redesign costs and months of back-and-forth.
Gus Petrakis put his name on this company in 2011 and he still answers the phone. Not a call center. Not a dispatcher who has never seen your roof. When you call about a Lakeway install, you get Gus or someone on his own crew at (877) 550-6892, and if the work isn’t done right, the 90-Day Done Right Promise means one call brings him back. That’s the standard we have held through hundreds of Hill Country installs.
We also don’t ask you to sign anything on the first visit. Bring me a bill, I’ll bring you the math. Take two weeks. Think about it. The price will be the same. If a salesman needs an answer tonight, the answer is no.
Our Solar Panel Installation Services in Lakeway
Rooftop Solar Installation
Most Lakeway roofs are hipped, multi-gabled, or steeply pitched, which means we’re designing around interrupted planes rather than one big south-facing slab. A straightforward 14 kW rooftop system on a post-2000 custom home in 78738 typically falls between $32,000 and $46,000 before credits, depending on roof complexity and chosen equipment. Our Solar Panel Installation crews flash every penetration properly and run conduit through attic spaces so nothing visible crosses your roofline.

Solar System Design & Permitting
This is where Lakeway jobs either succeed or stall. The city requires full engineering drawings, wind-load calcs, and in some communities, an HOA design-review approval letter before permits move. We handle that entire stack in-house and pre-stage PEC’s application in parallel, because a stalled permit is the single most common reason a finished array can’t be energized for weeks. For custom homes over 4,000 sq ft, design and permitting generally runs $2,800 to $4,500 as its own line item.

Solar Panel Replacement
Panels on Lakeway homes take Hill Country hail, and older systems from the 2010s sometimes run microinverters that have aged out of warranty. We replace panels and inverters without disturbing the original racking or flashing, and we match Enphase or SolarEdge components to your existing string. Most single-panel replacements in Lakeway run $450 to $900 including the part and labor.

Roof-Mount & Tile Roof Solar
Tile roofs in Rough Hollow and Serene Hills need a different mounting approach than standing-seam metal or asphalt shingle. We use tile-replacement mounts rather than drilling through clay or concrete tile, which prevents cracked tiles and leak paths along the entire array. Count on $450 to $700 per tile replaced during install, depending on tile profile and roof pitch. Steep pitches above 7:12 add roughly 8 to 12 percent to total labor because of staging and safety requirements.

Common Solar Panel Installation Problems We See in Lakeway Homes
- HOA design-review rejections. Rough Hollow, Serene Hills, and The Hills each have community-specific rules about panel placement, conduit visibility, and roof-plane setbacks. Installers who don’t read the design guidelines before drawing plans get bounced back and burn a month on redesign. We submit the layout to the review board before we pull the city permit.
- PEC interconnection delays. The cooperative’s application queue runs four to six weeks longer than Austin Energy’s, and filing after construction is the classic mistake. We pre-stage the PEC application before permits, so the energize date lands days after the last panel goes up, not weeks.
- Shading losses on ridge and canyon lots. A hilltop home in Lakeway can lose 15 to 20 percent of estimated production to morning or afternoon shading from the limestone ridge itself or mature live oak canopy. We model shading per-parcel using actual roof and tree measurements, not a city-wide average, because a slope-facing array here behaves differently than the same array on flat ground.
- Tile and metal roof penetration leaks. Shoddy flashings on tile or metal roofs show up as ceiling stains a year after install. Gus’s own crew flashes every penetration with proper tile-replacement mounts or rubber-gasketed metal brackets, and the 90-Day Done Right Promise covers any roof leak tied to our work.

FAQs - Solar Panel Installation in Lakeway
PEC credits excess generation at a lower rate than Austin Energy’s Value of Solar tariff, which means a Lakeway system that relies on selling excess power back to the grid has a longer payback than an equivalent Austin Energy system. You offset this by sizing your array to your actual daytime usage and adding battery storage to capture what you would otherwise sell cheap. Call (877) 550-6892 and bring us your PEC bill. We will show you the year-25 output number, not the day-one brochure figure.
Yes. Both Rough Hollow and Serene Hills have design-review boards that must approve panel placement, conduit routing, and roof-plane selection before the city will issue a permit. We prepare the HOA submittal package as part of Solar System Design & Permitting and typically get a response within two to four weeks, depending on the board’s meeting schedule.
Yes, we use tile-replacement mounts that swap the tile where the bracket sits for a metal flashing, which keeps the surrounding tile row intact and eliminates the leak risk from drilling through clay or concrete. Tile-replacement mounting adds $450 to $700 per tile, and breakdowns of that cost are in every Lakeway quote we write.
PEC’s residential interconnection queue currently takes four to eight weeks from application to approval, which is four to six weeks longer than Austin Energy’s process. That’s why we pre-stage the PEC application before pulling permits, so by the time the system is installed, the approval is already moving and your panels can be energized days after final inspection rather than waiting on the utility.
Your position on the limestone ridge controls when the sun actually hits your roof. East-facing slopes get morning sun but lose afternoon production, and west-facing canyon walls do the reverse, while mature live oak canopy blocks morning light at certain times of year. We model your production per-parcel using actual shading data and panel azimuths, not a city-wide irradiance average, so the estimate you get matches the roof you have.
