Fast, Reliable Solar Panel Installation Across Keene
Solar panel installation in Keene, TX typically runs $18,000-$32,000 before the federal tax credit, and most of our Keene jobs are permitted and installed within 6-10 weeks.

If you’re reading this because a door-knocker quoted you one number and the fine print said another, you’re in the right place. Call (877) 550-6892 and bring us a bill. We’ll bring you the math.
Why Gus’s Solar Is Keene’s Preferred Solar Panel Installation Company
Keene isn’t a town where faceless national outfits build trust. It’s a place where you see the same faces at the hardware store, the university, and church on Saturday. Gus Petrakis has run this company since 2011 with a published address, a license number, and a phone that he answers himself. That matters in a community this tight-knit. When we install a system on one home near Southwestern Adventist University, the neighbors walk over and ask who did the work. And the answer is always the same: Gus’s crew, not a sub.
We serve Keene the way we’d serve our own street. A live person answers 24/7, not a voicemail tree. If your system underperforms three years from now, the call comes to us and Gus comes back, because his name is on the building and the work. In Keene, that’s not marketing. That’s the only way to operate.
Our customers in Keene have told us the same thing again and again: they’d rather pay a fair price to a face they’ll see at the grocery store than roll dice with a company that disappears after the paperwork clears. Every solar job carries the 90-Day Done Right Promise in writing. If it’s not done right, Gus makes it right. One call brings him back.
Our Solar Panel Installation Services in Keene
We handle the whole job, from the first bill review to the final utility sign-off. Here’s what that looks like for Keene homeowners. And before you wonder, no salesman will pressure you to sign tonight. If a salesman needs an answer tonight, the answer is no.
Rooftop Solar Installation
Most homes in Keene are single-story ranch builds from the 1960s through the 1990s with south- or west-facing rooflines that take solar well. We mount panels with flashing done right at every roof penetration. No caulk-and-hope shortcuts. In a hail corridor like Johnson County, proper flashing is what keeps a decades-old roof from leaking after the panels go up. Our crews are background-checked and uniformed, and you’ll know who’s on your roof before they get there.

Solar System Design & Permitting
Design in Keene isn’t a copy-paste exercise. Mature pecan trees, 100-amp panels, and Johnson County permitting quirks all shape the plan. We pull the permits, we handle the interconnection paperwork with Oncor, and we design to your actual utility bill, not a brochure estimate. Gus quotes the year-25 output, not the day-one brochure number. For older ranch homes, that often means planning a main panel upgrade before the inverter ever ships so the project doesn’t stall at inspection.

Solar Panel Replacement
If your panels are ten or fifteen years old and underproducing, or if hail took a toll and the manufacturer’s warranty math doesn’t work in your favor, we replace them. We work with Qcells, REC, and SunPower, among others, and we’ll tell you honestly whether replacement makes more sense than repair. Sometimes it does. Sometimes it doesn’t. You’ll get a straight answer either way, with real numbers attached.

Roof-Mount & Tile Roof Solar
Keene has plenty of composition shingle roofs, but a handful of homes near the university have tile or alternate roof profiles that need different mounting hardware. We don’t hand that work to a sub. Gus’s own crew installs every rack and rail, and we warranty the roof penetrations right alongside the panels. If your roofer later says something looks off, call us. We’ll come out.

Trusted Brands We Service in Keene
We’re brand-agnostic in the way that serves you best. After 29 years in the trade, Gus has seen which inverters hold up under North Texas heat and which panels survive hail season with their output intact. We install and service equipment from Qcells, REC, SunPower, Panasonic, Enphase, SolarEdge, Tesla, and FranklinWH. For Keene customers, that means we can usually match the right panel to the right roof and the right inverter to the right panel upgrade. No forced fit, no leftover inventory push.
Common Solar Panel Installation Problems We See in Keene Homes
- Aging 100-amp electrical panels. Homes built from the 1960s through the 1990s around the university often carry 100-amp services. A grid-tied inverter plus your AC load can push that past code. We flag this in the proposal, not at the inspection.
- Hail anxiety, not panel quality. Keene sits in North Texas hail country, and homeowners here remember storms that dented cars and shredded shingles. If we don’t address IEC 61215 impact ratings and insurance coordination in the first conversation, we haven’t done our job.
- Mature pecan shade on west-facing lots. Some older homes have beautiful pecan trees that wreck a naive production estimate. Microinverters or careful azimuth planning can recover most of the loss, but only if we model the shade before we quote.
- Roof age at the time of install. A solar array outlives an aging roof, and pulling panels for a re-roof is expensive. If your shingles have five years left, we’ll tell you to replace the roof first. That’s the neighborly answer, even when it’s not the easiest sale.
Pricing for Solar Panel Installation in Keene, TX
A typical rooftop solar installation in Keene runs $18,000-$32,000 before the federal tax credit. That’s for a system sized to a 1,800-2,600 square foot ranch home with average Johnson County electricity consumption. A main panel upgrade from 100 to 200 amps runs $2,500-$4,500 depending on the age of the wiring and the condition of the service entrance. Solar panel replacement of an older array, including removal and reinstall, typically runs $3,500-$7,000 for a standard 10-14 panel system. Hail-related repair, where panels are replaced but racking stays, lands lower. Every quote comes off your actual utility bill, not a generic table, and the number we quote is the number you pay. Free estimates, no trip charge inside our own county, and a senior and veteran 10% discount that never expires. Call (877) 550-6892 for an exact quote on your home.

FAQs - Solar Panel Installation in Keene
A 100-amp to 200-amp panel upgrade in Keene typically runs $2,500-$4,500, with the final number depending on the age of your service entrance, how the old panel was wired, and whether the meter socket needs replacing. We scope this during the design phase so it’s in your quote from day one, not a surprise change order. Call (877) 550-6892 and we’ll give you a real number for your specific home. Estimates are free.
No. Modern panels from Qcells, REC, and SunPower carry IEC 61215 impact ratings built to survive the hail sizes we see in Johnson County, and we’ll walk your insurance agent through the documentation they need. What hail risk does mean is that flashing, mounting, and panel choice deserve more attention here than in a calmer market. We’d rather you ask hard questions than skip solar out of worry.
Keene residents are in Oncor’s delivery territory, which means your retail electric provider buys back excess generation under the plan you choose. Some REPs offer true 1:1 net metering; others credit at a lower avoided-cost rate. We run the year-25 output math off your actual bill and show you exactly which plan makes the system pay for itself fastest. Bring us a bill, we’ll bring you the math.
Yes, and we’ve done it many times. On a 1970s ranch off Mesquite Street, our crew upgraded a 100-amp panel to 200 amps before mounting Qcells panels on the south-facing roof. Another company had told the homeowner that rapid shutdown would require rewiring the entire attic, but our design team mapped a single-string layout that avoided the old wiring and passed Johnson County inspection on the first visit. Older homes need a careful hand, not a cheaper quote.
Usually, yes. Mature pecan trees cut into production on west-facing roofs, but microinverters recover much of that loss because each panel operates independently. We model the shade before we quote, using actual satellite data for your roof, so you know the real year-one and year-25 production numbers before you spend a dollar. Sometimes the honest answer is that the tree is worth more than the panels. We’ll tell you that too.
