Why Seguin Homeowners Choose Gus’s Solar
Most solar companies that knock on doors in Seguin aren’t from here. They roll through with a leased sales crew, quote a number that changes by the time you see the contract, and disappear once the paperwork clears. Gus Petrakis does things differently. His name is on the truck, his license is published, and he’s the one who answers when you call about a production question three years after install. That’s why homeowners along Court Street, in the Meadows subdivision, and throughout the historic downtown district keep our number saved.
We serve Seguin from our scheduling office just down the road in San Antonio, so response times are measured in hours, not days. Every tech who climbs onto your roof is background-checked, uniformed, and part of Gus’s own crew. We don’t hand your job to a subcontractor. We don’t ask for a signature tonight. And we back every install with the 90-Day Done Right Promise: if it’s not right, we make it right, in writing.
Solar Services We Offer in Seguin
Solar Panel Installation
We design systems around your actual SME bill and the orientation of your roof, not a generic brochure calculation. Older pier-and-beam homes near downtown often need a panel upgrade first, and we’ll tell you that before you spend a dime.
Learn more about our Solar Panel Installation in Seguin.

Solar Battery Storage & Backup
Seguin sits in a hail corridor and sees its share of storm-driven outages, especially in the spring. That’s where our Solar Battery Storage & Backup in Seguin comes in, keeping your refrigerator, well pump, or medical equipment running when SME’s grid takes a hit.

Solar Panel Cleaning
Between the spring pollen drop, dust off the surrounding farmland, and the occasional caliche haze, Seguin panels collect a film that quietly trims output. We recommend checking production trends before assuming your system is fine.

EV Charger Installation
More Seguin garages are housing EVs every year, and EV Charger Installation - Seguin with a Level 2 charger off your existing panel can save hundreds versus public charging. We’ll check your panel capacity and load before recommending an amperage.

Solar Panel Maintenance & Monitoring
Gus monitors the systems we install, so we often call you before you notice a drop in output. Annual inspections catch loose connections, degrading sealant, and critter damage before they become expensive repairs.

Solar Panel Repair
Hail storms tracking northeast off the Edwards Plateau have dented plenty of panels in Guadalupe County. If your system took a hit or a string inverter is throwing faults, we diagnose the actual problem and quote the fix honestly.

Commercial Solar Installation
Seguin’s industrial parks along I-10, including the manufacturing campuses near Caterpillar, run serious demand charges under SME’s commercial rates. Rooftop solar can shave those peaks, and we’ll run the numbers off your actual utility data.

Neighborhoods We Serve in Seguin
We work all over Seguin, from the older streets near Texas Lutheran University to the newer subdivisions pushing north and east toward I-10. Our crews are typically at your door within one to two business days for estimates and same-week for most repairs.

Why Seguin’s Climate & Housing Affect Solar
Seguin averages around 5.4 to 5.6 peak sun hours per day year-round. That’s a strong number, and it means a properly sized system here produces enough to justify the investment quickly. But Seguin also sits squarely in the South-Central Texas hail corridor. Storms that form west of the Edwards Plateau and track northeast regularly drop golf-ball-sized hail over the 78155 and 78156 ZIPs, and we’ve replaced panels in Seguin after exactly those events. That’s why we talk about IEC 61215 impact-resistance ratings and hail-specific warranty language during every sales conversation here. It’s not a scare tactic. It’s local reality.
The housing stock splits in two directions. Homes built between the 1920s and 1960s near downtown often sit on pier-and-beam foundations with original electrical panels that cannot handle a modern solar array without an upgrade. We tell you that upfront, before you sign anything. The post-2010 brick-veneer subdivisions on the north and east edges of town are generally easier jobs: simple hip and gable roofs, strong structural framing, and modern panels ready for solar. Knowing which type of house you have changes the quote, the timeline, and the total cost.
Pricing for Solar in Seguin
Bring us your SME bill and we’ll bring you the math. That’s how Gus quotes every job in Seguin: off your actual usage, your actual export rate, and the year-25 output your roof can realistically produce, not the day-one brochure number. You’ll get a written quote with a line-item breakdown and no surprises later. The price we show you is the price you pay.

FAQs About Solar in Seguin
SME runs its own interconnection queue and export compensation tariff, separate from CPS Energy in San Antonio and GVEC in the surrounding county. The rates and approval workflow differ, which is why we handle the SME paperwork directly for every Seguin job. Call (877) 550-6892 and we’ll walk you through how SME’s current tariff affects your payback period.
Most residential installs in the 78155 and 78156 ZIPs take two to four days of on-site work after permits clear. SME’s interconnection approval timeline can add one to three weeks depending on their queue, and we track that for you.
If your home was built before the 1970s and still has its original panel, there’s a good chance the answer is yes. We’ll inspect it during the estimate and tell you honestly whether an upgrade is required, optional, or unnecessary before you commit to anything.
Hail in this corridor can crack glass and reduce output even when panels look fine from the ground. If a storm hits your neighborhood, call us for an inspection. We check production data, test string output, and document damage for your warranty claim. You get a live person on the phone, not a ticket queue.
For most Seguin homes, yes, especially if your cooling load drives summer bills over $200 a month. The math depends on your roof orientation, your actual usage, and SME’s current export rate. Bring us a bill and we’ll run the year-25 numbers, not the sales brochure version. Estimates are free, and you’re under no obligation to decide today.

What Seguin Customers Say
"Panel level monitoring so I can see each one, proper stainless clips under the array rather than zip ties, and he walked me under it with a torch to show me before he signed off."
- Cassius Delacroix"Gus's own crew did the install. Not a subcontractor who had never met him, which is what the big outfit quoted me and could not tell me who would actually be on my roof."
- Aurelia Santibanez"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
