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, and 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.


Our Clients
Our clients range from firms with just a few employees, to medium and large "solar" contractors, to "Fortune 50" firms. If the project involves solar energy in any manner, we can be of benefit to you!
 

For Solar Sales Firms and Solar Installation Contractors:
If your company is involved in the sales and/or installation of residential systems, commercial systems, utility-scale systems, or all of the preceding .. we can make tasks easier and faster for you! In the case of residential and many commercial projects, we'll send a simple PDF for you to fill out and return to us. Larger projects will require more information. From information you provide to us, we'll design the system for you, including a Texas Professional Engineer's seal on the documents as required. Electrical permit application packets we'll send to you include: Line diagrams, wiring calculations, site diagrams, product cut sheets, utility-grid intertie documents (as available and/or required by the utility company), and others. Permit packets vary in size depending on the system location and utility company, and typically contain from 12 to 22 files.

 

Whether you're a residential solar sales and installation firm that requires help from a Texas-based customer-friendly solar design firm .. to a medium-sized company that can't yet afford a full-time Professional Engineer on staff .. to a large "EPC" (Engineering, Procurement & Construction) firm that can benefit from exceptional and very knowledgeable engineering assistance for a multi-million dollar solar farm .. we're ready to assist!

Immediate Benefits to You:

1. We're "Texas" local. (Advantages to you and your customers are obvious.)
 
2. Typical turn-time for standard residential PV designs is 2-4 days. Expedited service can be as fast 24 hours. (Unusual or non-typical systems may take longer.)
 
3. Commercial and utility-scale designs are available in size from kilowatts to megawatts. Complete electrical document packets are provided to you for Permitting Inspector review and approval.
 
4. We're known statewide among municipal Code and Fire Officials, Inspectors, utilities, and others. If you encounter problems with any aspect of permitting or inspection, we'll communicate with them to help resolve the issue(s), typically at no charge to you.
 
5. Sales Assistance. Do you have a commercial project that may benefit by having a Professional Engineer accompany you to your customer's site? We may be available to assist. (You can't get THAT kind of help from an out-of-state firm!)
