North Texas Renewable Energy Engineering

Who We Are

North Texas Renewable Energy Engineering (“NTREE”) is an employee-owned, fully independent solar and renewable energy consulting, design, and engineering firm.

We realize you have many choices within the solar energy industry among solar energy sales firms, design engineers, installation contractors, and others.  We believe we can qualify ourselves to you in one sentence:

We’ve been involved in solar energy since 1972.

What We Do
We consult, advise, design solar energy systems, teach, diagnose problems, and much more.  (See our “About Us” page for details.)  We routinely go “above and beyond”, performing extra steps on your behalf to help ensure the success of your project.

We know solar energy well enough to translate any aspect of it into plain English, understandable by all.  Have questions?  We’ll be glad to provide answers in a manner YOU can understand – guaranteed.

We don’t sell or install solar equipment, nor do we represent any brands or types of products.   This allows us to recommend hardware that most appropriately fulfills your requirements.  If you aren’t certain of those requirements, we can help there too!  To assist in that aspect, we developed a VERY comprehensive energy analysis report based on actual consumption data routinely available from utility companies.  You can download a sample Report from our “Our Services” page in the “Consultation” section.
