What Our Customers Say

"I am absolutely thrilled with my recent solar installation - a 10.08 kW system with 9.3 kWh battery. Ian was great to work with from day one; his quote was clear and informative, with all of the data I needed to move forward with the project with confidence. The installation was clean and efficient and the system has been working as designed! Ian has also been very responsive to my post-installation questions. I would recommend GTRE without any hesitation!" ~ Louise N.

The state inspector had nothing but great things to say about their workmanship. From a customers point of view the install was super clean and they worked hard to address all of my cosmetic concerns." ~ Trevor F
