Solar Panel Installation
Our solar panel installations utilize high-efficiency panels from trusted brands like REC and Q CELLS. Systems are custom-designed to maximize energy production based on home orientation and energy usage. Backed by 25-year performance warranties, our installations ensure long-term savings and reliability. We handle permits, roof integration, and grid connection for a seamless experience.
Battery Backup Systems
We integrate battery solutions like Tesla Powerwall and FranklinWH to store excess solar energy. These systems provide power during outages and optimize usage during peak rate hours. Our engineers ensure proper sizing and compatibility with existing solar setups. Installation includes smart monitoring for real-time energy tracking and management.
Maintenance & Repair
We offer proactive monitoring and maintenance for systems we installed. Services include panel cleaning, inverter diagnostics, and hail damage repairs. Our team responds promptly to service requests and coordinates roof work with solar reinstallation. We prioritize quick resolution to minimize energy loss.
Commercial Solar
Tailored solar systems for commercial properties reduce operating costs and meet sustainability goals. Our engineers design scalable installations for warehouses, offices, and agricultural facilities. We handle large-scale projects with minimal disruption and ensure compliance with business energy requirements and tax incentives.
Roof Reset Services
We remove and reinstall solar panels during roof replacements or hail damage repairs. Our team coordinates with roofing contractors to ensure proper panel handling and reinstallation. This service preserves system performance and warranty while protecting home investments during structural work.
Questions
Does solar work during power outages?
Yes with battery backup. Solar panels alone don't power homes during outages, but adding a battery like Tesla Powerwall ensures continuous energy supply.
How much do solar panels cost in Texas?
Costs vary by system size, but most Texas homes pay $15,000-$25,000 after federal tax credits. We offer 0% down financing options to make solar affordable.
Can I install solar if I rent?
Rental property installations require landlord approval. Tenants without approval can advocate for solar adoption through our community program partnerships.
Do you service existing solar systems?
We only service systems we installed to maintain warranty standards. For third-party systems, we recommend contacting the original installer for continued support.
What happens during hail storms?
Our hail damage service quickly removes and reinstalls panels during roof repairs. We coordinate with trusted roofing partners to minimize downtime and ensure proper system reintegration.
How long does installation take?
Most residential installations complete in 1-2 days. Commercial projects vary by size, with timelines provided during our initial consultation process.

We had our solar panels installed and it went very well. We ordered the batteries at the same time and it has not gone as smooth. They installed the batteries 30+ days ago and attached them to the house which is step 1 of 3 steps before they will will work. The account manager for me never calls me. She committed to call me on Fridays with an update. I call every week for an update and she tells me she will call me on the following Friday. She never follows up and never remembers what stage my project is in. We were so excited to work with a local company and it has been very frustrating.

It is going on two years now that we have our solar panels. In that time, we've had to file six support calls. Four times for faulty cell cards. Twice for complete failure of the system. The support team is understaffed and has to support faulty equipment. Response times are measured in weeks, not days. Overall, a very disappointing experience for such a large investment. Just had the solaredge inverter replaced. New unit lasted exactly six hours and it broke. In the two years I've had the system, it's been down for three months.

Longhorn Solar installed on 09-09-19 The cell card inverter keeps malfunctioning You have to monitor the progress if all inverter ate producing solar, I have to call for service 5 times to replace cell card for the inventor after spending 65k after tax credit Out of 4 inventors only 3 work most of the time The company does not ignore the service call, but it takes almost 3 weeks plus ton address the issue and most importantly considering this Solar system around 2.5 yr old if it's causing so much problem now, I am concern as the system get old it will be mostly nonfunctional Sales dept is great, product can be better, service can can be faster

The whole process, from initial inquiry to final decision, was pleasant and professional. Ronald took the time to walk us through their project proposals twice over zoom, and responded to a number of follow-up questions we had. The sales presentation included an appropriate amount of detail that allowed us to make informed choices. Although we ultimately decided to go with another company for our solar project, I would not hesitate to consider Longhorn in the future.

What a positive experience from start to finish. I felt like I was being educated and consulted with, rather than sold to. After the installation, my account manager has checked in and answers questions very quickly.

Longhorn Solar has been so easy to work with, Monte has always been quick to answer my questions in a polite and professional manner. Realizing this is a big decision with so many variables at play, I feel confident trusting Longhorn Solar with my business.

Despite my circumstances changing after my initial inquiry that prohibits me from moving forward with LONGHORN SOLAR's proposals, I wanted to express gratitude for KATHY MILLEN's support. She patiently clarified multiple "What-if." questions and adjusted configurations across several calls and Zoom sessions exploring not only the pros/cons of various technology options, but also how very recent utility regulatory changes would negatively affect my original project investment's goals.
By the end - her straightforward approach was more a respectful mutual discovery process than targeting me as a "sale to close" (as I'm way to accustomed to). I highly encourage anyone considering solar for their home to find Kathy Millen at Longhorn Solar.
