If you live in Lake Dallas and you’re wondering whether solar makes sense on a lake cottage from the 1960s, the short answer is usually yes, but it takes a little more care than the door-knockers will tell you. Solar panel installation in Lake Dallas typically runs between $15,000 and $32,000 before incentives, depending on whether your home needs a panel upgrade or roof reinforcement first. Gus’s Solar has been doing this work long enough to give you a straight answer about what your specific house needs, and you can reach a live person at (877) 550-6892 around the clock. We are not the crew that vanishes three weeks after the check clears.
Gus Petrakis puts his name on every job, and he has been at this since 2011. The 90-Day Done Right Promise means exactly what it sounds like: if something is not right, one call brings Gus back, in writing, on every install. No fine print, no “that’s covered on page 14 of your warranty.”

Why Lake Dallas Homeowners Choose Gus’s Solar
Lake Dallas is a small town in the truest sense, and word travels fast down Hundley Drive and along the streets around Lake Dallas City Park. When your neighbor asks who did your panels, we want you to say a name, not a 1-800 number. Gus’s crew earns that by showing up when they say they will, with background-checked, uniformed technicians on every job. No subs. The same people who quote the work are the ones on the roof flashing every penetration correctly.
We work throughout the 75065 ZIP code regularly, from the older homes near Swisher Road to the newer construction off Corinth Parkway. The housing stock here is genuinely mixed: post-WWII lake cabins turned permanent residences sit right alongside 1990s and 2000s infill builds. That matters because the older cabins frequently have 100-amp electrical panels that need upgrading to 200-amp service before any grid-tied solar system can pass inspection and go live. We handle that upgrade as part of the job, not as a surprise “change order” two days in.
Gus’s Solar also offers a Senior and Veteran 10% discount that never expires, plus a Free Second Opinion on Any Written Estimate. If another company quoted you a system and it feels off, bring it to us. We will look at it honestly, even if the answer is that their quote was fine.
Solar Services We Offer in Lake Dallas
Solar Panel Installation
We design residential systems around your actual usage from your actual utility bill, not a brochure. For Lake Dallas homes with limited roof space, we prioritize panel placement on south-facing planes to maximize production per square foot.
Learn more about our Solar Panel Installation in Lake Dallas.
Solar Battery Storage & Backup
Lakefront homes in Lake Dallas sit in a hail-prone region where storms can knock out power. A battery backup system keeps refrigerators, medical equipment, and essential circuits running when the grid drops.
Learn more about our Solar Battery Storage & Backup in Lake Dallas.
Solar Panel Cleaning
Proximity to Lake Lewisville means higher humidity and more algae, pollen, and mineral buildup on glass surfaces than neighborhoods further inland. Annual cleaning on lake-proximate systems typically recovers 5 to 15 percent in lost production.
Learn more about our Solar Panel Cleaning in Lake Dallas.
EV Charger Installation
If you have an electric vehicle and solar, a Level 2 charger keeps your operating costs near zero. We install chargers as standalone projects or as part of a full system package.
Call (877) 550-6892 to schedule a free EV charger site visit in Lake Dallas.
Solar Panel Maintenance & Monitoring
We monitor your system’s production and call you if something looks off. You should not have to check an app every morning to make sure your system is actually producing. That is our job.
Call (877) 550-6892 for maintenance and monitoring plans in Lake Dallas.
Solar Panel Repair
We repair inverters, damaged panels, wiring faults, and monitoring issues. If a storm hits and something breaks, we want to be the phone number you dial, not a ticketing portal.
Call (877) 550-6892 with the issue; $40 off any repair over $200.
Commercial Solar Installation
We install grid-tied commercial systems for small businesses, offices, and multi-tenant properties in and around Lake Dallas. Pricing is based on your actual demand profile and roof geometry, not a generic square-footage estimate.
Call (877) 550-6892 for a commercial site evaluation.
Neighborhoods We Serve in Lake Dallas
We serve the entire 75065 ZIP code, and have spent many days working in these parts of town:
- Lake Dallas Estates - mid-century and 1970s builds with the complex roof lines common along the lakeshore.
- Villages of Lake Dallas - newer construction with larger, simpler roof planes that often take arrays easily.
- The streets around Lake Dallas City Park - a mix of original lake cabins and rebuilt homes needing structural review before install.
- Homes off Swisher Road and Hundley Drive - where we handle many of the older 100-amp panel upgrades.
Most jobs in Lake Dallas are scheduled within 5 to 10 business days of the site visit, weather permitting.
Why Lake Dallas’s Climate & Housing Affect Solar
Lake Dallas sits on the northern shore of Lake Lewisville, and that lake-facing orientation gives many properties a southward rear elevation. In solar terms, that is ideal: a south-facing array captures the most direct sun across the day. But the catch is structural. Many of those lake-facing homes began life as compact weekend cottages in the 1950s through the 1970s. Their roofs were never engineered for the additional load of a racking system and panels. We regularly send a structural evaluation before we quote a final number, because a “simple install” on an original lake cabin here sometimes requires rafter reinforcement first. Homeowners in flat-grid suburbs like Corinth simply do not deal with that same tension between great orientation and constrained framing.
Then there is the hail. Denton County sits in Texas’s severe hail corridor, and golf-ball-sized hail events hit this area multiple times per decade. That is why we recommend IEC 61215 Class 4 impact-rated panels on Lake Dallas installs as the practical standard, not an upgrade. If you are going to put glass on a roof in a hail corridor, it should be glass built for that environment.
We also account for humidity near the lake. It is not the same as a roof in arid west Texas. Marine-grade aluminum racking and properly sealed MC4 connectors prevent the kind of slow corrosion that shortens system life. It is a small detail, and it matters.
Pricing for Solar in Lake Dallas
What you will pay depends mostly on system size, panel type, roof condition, and whether your electrical panel needs an upgrade. Here is what we typically see in Lake Dallas:
- Small system (4-6 kW) - $12,000 to $18,000 before incentives.
- Mid-size system (7-10 kW) - $18,000 to $28,000 before incentives.
- Large system (11-15 kW) - $28,000 to $42,000 before incentives.
- Battery backup (single unit) - $9,000 to $16,000 depending on brand and capacity.
- Electrical panel upgrade (100-amp to 200-amp) - $2,500 to $4,500 when required.
- Roof reinforcement on older lake cabins - quoted after structural review; we will tell you before we quote the full job.
Every quote uses your actual utility bill. Bring me a bill, I will bring you the math. And take two weeks to think about it. The price will be the same.

FAQs About Solar in Lake Dallas
A typical residential solar installation in Lake Dallas runs between $15,000 and $32,000 before incentives, with older lake cabins on the higher end when roof reinforcement or a panel upgrade is required. Every quote is built from your actual utility bill, not a brochure number. Call (877) 550-6892 for an exact quote; estimates are free.
Many do. Homes built as weekend cottages commonly still run on 100-amp electrical panels, and a grid-tied solar system generally requires 200-amp service to pass inspection. We handle the upgrade as part of the job and tell you about it during the initial site visit, not after the contract is signed. Call (877) 550-6892 and ask about a panel assessment.
Yes, if the panels are rated for it. We recommend IEC 61215 Class 4 impact-rated panels as standard in Lake Dallas because Denton County sits in Texas’s severe hail corridor. These are panels tested against hailstone impacts. The rating is what makes solar durable here. For a system designed around local conditions, call (877) 550-6892.
Yes, and that is often the best orientation. In Lake Dallas, many homes have their best roof plane facing south toward the water, which captures the most sun. The catch is that an array on the rear elevation may trigger HOA aesthetic review in some communities. We handle that process and include it in the timeline. For a site review of your roof’s orientation, call (877) 550-6892.
For most Lake Dallas homes, we can have a technician out within 24 to 48 hours for emergency repair issues, and regular site visits are typically scheduled within 5 to 10 business days. If you need help now, call (877) 550-6892; a live person answers, day or night.

What Lake Dallas Customers Say
"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"Told me straight that a battery did not make sense for how we use power and sold me the array without it. He talked himself out of a good deal of money that afternoon."
