I researched several solar supply companies and decided that RENVU had the best selection of solar equipment. I ordered all of my equipment using their planning program on their website. I also bought the permitting service after I ran into problems with Pima County and Arizona Public Service. Dean Armintrout patiently helped me through the technical problems that these agencies kept throwing at me. I definitely advise using the products and expert help from RENVU SOLAR. I really value the assistance I received. Both Dean and Chris were extremely helpful to this DIY guy. I live in the Arizona Sonoran desert where air-conditioning is very expensive in the summer. I saved thousands of dollars and have a system that is providing the average annual cost per month of my electricity which is @$185 per mo. THANK YOU, RENVU!!
