The North American Board of Certified Energy Practitioners (NABCEP) is a nationally-recognized, certification program for photovoltaic (PV) solar system installers. Certified installers must have a certain amount of work solar experience, pass a rigorous exam, sign a code of ethics, and take continuing education courses for re-certification every three years.

What Clients Say...

"Greene Tech did a great job. It's exactly what I had hoped it would be. The install was basically perfect. The symmetry of the install was perfect. All electrical connections and conduit runs are perfect as well. It really is as I describe it and I would recommend them to anybody!"
