Who We Are

Texas Engineered Solar — Built on Expertise, Not Just Sales

TXEN stands for Texas Engineered. We're not a national sales organization with local subcontractors — we're a San Antonio-based team with genuine engineering backgrounds doing the work ourselves.

Our team brings experience across solar cell and module manufacturing, residential and commercial construction, structural engineering, and electrical engineering. That foundation shapes everything we do — from how we design a system to how we stand behind it after the job is done.

We install residential solar, battery backup systems, standby home generators, and we repair and service existing solar systems — including systems we didn't originally install. If your solar system isn't performing or your installer is no longer around, call us.

  • 🏠 Residential homeowners are our primary focus — we are not a commercial-only company
  • 🔧 We repair and service solar systems installed by any company, any brand
  • ⚡ Battery backup and generator integration alongside solar — all under one roof
  • 📍 Every team member lives and works in Texas — we're part of this community

Our Background

The Expertise Behind Every Install

Our team's combined experience spans multiple engineering and construction disciplines — giving us a technical depth that most solar companies simply don't have.

☀️

Solar Manufacturing

Experience in solar cell and module manufacturing means we understand how panels are made, how they fail, and how to spec the right equipment for each project.

🏗️

Construction

Backgrounds in residential and commercial construction give our team the ability to assess a roof, plan a structural install, and execute a clean, code-compliant job.

📐

Structural Engineering

We understand load paths, rafter spans, and roof systems. Our installs are designed so the structure supporting your panels is as solid as the panels themselves.

⚡

Electrical Engineering

From inverter sizing and string design to battery integration and generator transfer switches — our electrical knowledge drives safer, better-performing systems.

  • ✔ Texas Veterans Commission Veteran-Owned Business (VOB) — state recognized
  • ✔ Military discount available for veterans and active duty service members

The TXEN Family of Companies

Built on 20+ Years of Engineering & Installation

TXEN Solar is a subsidiary of Engineering & Installation (E&I) Contractors — a telecommunications construction company that has been building communication infrastructure across the state of Texas since 2001.

E&I Contractors derives its name from the US Air Force squadron our founder served in. That background — precision construction, structural integrity, and engineering discipline — is in TXEN Solar's DNA.

When you hire TXEN Solar, you're not hiring a startup or a national franchise. You're working with a company backed by over two decades of active construction operations right here in Texas.

What We Stand For

How We Do Business

We believe a homeowner making a major energy investment deserves honesty, clarity, and a company they can hold accountable after the job is done.

🎯

Precision Over Speed

We don't rush installs to hit volume targets. Every system we put in is sized correctly, mounted properly, and wired to perform for 25+ years.

🤝

Honest Recommendations

We'll tell you if solar doesn't make sense for your situation. We don't sell extras you don't need, and we don't inflate system sizes to hit a commission.

📞

Direct Access to Local Experts

When you call TXEN Solar, local experts answer — not a national call center. You'll always have a direct line to the people responsible for your system.

🔬

Engineering-Backed Decisions

Every recommendation we make is backed by real analysis — production estimates based on your actual usage, roof condition, and local solar data.

🏘️

Rooted in San Antonio

We live in the communities we serve. We're not going to install your system and disappear. We'll be here for maintenance, repairs, and questions years from now.

🔄

We Fix What Others Installed

If your existing solar system is underperforming or your original installer is gone, we'll diagnose and repair it — regardless of who installed it or what brand it is.

Real Work. Real San Antonio Homes.

Projects We're Proud Of

Every install is local. Every system is engineered for the home it's on.
