I am so pleased with Hot Purple that I have recommended them to a good number of my neighbors. They met with me and ultimately installed a 30-panel, 9.6 kW system more than a year ago. (We are in the desert area of Palm Springs.) Description: honest, honest, honest… not to mention communicative, technically bright, responsible, detail oriented, quality installation. After much research – by both Hot Purple and me – we apparently sized the system correctly. At our 1-year anniversary, our 12-month SoCalEd electric bill was about $75. Further, even the company they recommended for periodically cleaning the panels (important) has been timely, affordable, and professional.
