Commercial and industrial solar solutions for Texas businesses, campuses, and communities. Longhorn Solar locks in your energy costs for 25 years and keeps the Lone Star burning bright.
Not a slogan — a fact. Texas receives more solar energy per square foot than almost anywhere in the country. Longhorn Solar exists to put that resource to work for Texas businesses, communities, and the land itself.
With more than 300 sunny days a year, a deregulated energy market, and some of the most favorable commercial tax incentives in the country, going solar in Texas isn't just smart — it's the natural next move for any business serious about its long-term costs.
Longhorn Solar brings commercial and industrial solar expertise to Texas operations of every size — from single-facility rooftop deployments to multi-site campus ground-mount configurations. We design, deploy, and monitor everything so you can focus on running your operation.
And because Longhorn Solar is a Seebury company, your system can be integrated into a broader DESAEAT multiservice energy strategy — pairing solar with gas backup, Tesla Megapack storage, or waste-to-energy depending on what your environment actually demands.
Texas's vast open landscape, intense sun, and wind resources make it the nation's premier commercial solar environment.
Ground-mount and rooftop commercial installations — engineered for your facility's specific orientation, load profile, shading conditions, and long-term energy goals.
Fully integrated Solar Roof installations for commercial and institutional properties — generation built directly into the structure, no racking required.
Utility-scale battery storage that turns your solar array into a true 24-hour energy asset — storing daytime generation for overnight and peak demand coverage.
Fleet and workplace EV charging infrastructure — Wall Connector networks and commercial-grade installations powered by your own solar generation, not the grid.
Real-time performance monitoring, predictive maintenance alerts, and continuous optimization — keeping every panel producing at peak efficiency, every single day.
Solar as part of a larger Seebury multiservice energy strategy — paired with natural gas, wind, or waste-to-energy for operations that need more than solar alone can deliver.
Solar Sentinel is Longhorn Solar's proprietary monitoring and optimization platform — giving you real-time visibility into your system's performance from any device, at any time.
Most solar companies install and walk away. We stay. Solar Sentinel means a Longhorn Solar engineer is watching your system around the clock, catching issues before they become outages and continuously tuning for maximum output.
Sometimes it is. But Longhorn Solar operates under the Seebury DESAEAT methodology — Design Energy Solutions Around the Appropriate Energy Allocation by Technology. We start with your environment and work backward to the right solution, not the easiest sale.
That honesty is what makes Longhorn Solar different. If straight solar is right for your facility, we'll tell you. If you need solar paired with gas or battery storage to meet your 24-hour operational needs, we'll design that instead.
Learn About DESAEAT →Maximum independence. Solar generates, Megapack stores, grid backs up. Best for operations needing predictable costs and true resilience.
Gas as your backbone, solar as your 25-year cost lock. Offsets daytime load and shields you from gas market volatility for the life of the system.
Wind peaks when solar doesn't. Together they deliver near-continuous renewable coverage across all 24 hours and all Texas seasons.
Tesla's commercial solar panels deliver industry-leading efficiency and durability — built for Texas heat and designed to produce maximum output over decades of operation.
Solar Roof integrates generation directly into the building structure for properties where traditional racking is impractical or aesthetically unsuitable.
Tesla Megapack is the gold standard in commercial and utility-scale battery storage. A single unit stores up to 3.9 MWh — enough to power a large commercial campus through the night.
Paired with a Longhorn Solar array, Megapack turns your solar investment into a true 24-hour clean energy asset with proven reliability at scale.
Longhorn Solar designs and installs commercial EV charging infrastructure — from workplace Wall Connector networks to high-throughput fleet stations — powered by your own solar generation.
We handle permitting, installation, and ongoing monitoring so your parking lot becomes a sustainability-demonstrating, cost-reducing asset.
We're not a national company parachuting in. Longhorn Solar is rooted in McGregor, Texas. We know the ERCOT grid, the state incentive landscape, and what Texas operations actually require.
Solar Sentinel means Longhorn Solar stays actively engaged with your system's performance long after commissioning — monitoring, optimizing, and alerting continuously, not just at the quarterly check-in.
As a Seebury company, Longhorn Solar can integrate solar into a broader multiservice energy strategy — adding gas backup, battery storage, or DESAEAT configurations that no standalone installer can offer.
Solar locks in a portion of your energy cost for the life of the system. As Texas utility rates rise — and they will — your solar generation becomes more valuable every year. We model that return from day one.
As president of Seebury, Patrick Stansbury leads energy projects that drive investor value on tribal lands, commercial properties, and federal facilities across Texas and the Southwest. With decades of project development experience, Patrick built the Seebury model around one insight: energy projects fail in execution, not in vision.
The Seebury 6D Development Process is the answer — a disciplined six-stage methodology that takes every project from initial site discovery through long-term facility defense and continuous improvement.
Strategic partnering is something everyone talks about — rarely are these relationships developed in a successful manner. At Seebury we seek to develop successful joint ventures and project consortia that deliver value to all participants. No organization can do everything.
We serve commercial and industrial clients across Texas. Reach out and we'll put together a no-obligation site assessment and energy analysis for your property — no pressure, just numbers.
