Ask these questions before
choosing a solar company

Are their installers NABCEP "PVIP" Certified?

There are different types of NABCEP certifications. The only one you should trust is the PVIP certification. Ian Huddleston is the longest-standing NABCEP PVIP Board Certified professional in 100 miles of Johnson City, TN. #PV-041115-010730

Are their installers local or subcontracted and brought in from out of the area?

Our installers are our family and have many years of installation and service experience, and live in homes powered by solar systems.

Do they have a solar system on their own home?

Has the salesperson installed a solar system?

GTRE doesn't employ any salespeople. Our reputation and competitive pricing have sustained our company since 2008.

Is the company's owner on the roof with the install team or do they just work in an office?

Ian has been on every single installation job since 2008. So the company's owner is personally involved in every step of the process. 

Our primary home in Washington Co. and a model home in Sullivan Co. are both 100% off-grid. Our home in Johnson City has a solar system with battery backup and is connected to Brightridge.
