Sunwork did a terrific job for me on my home solar panels. Once I made the decision to install panels, they took care of everything else: home inspection, system design, permitting, materials, labor, and even helping me to file necessary paperwork to get my tax credits. I interviewed several solar contractors before selecting Sunwork. They were head and shoulders above the rest, and brought a clear philosophy of working to deliver a fantastic final product and answering all my questions along the way. Project manager Reuben Veek is a pleasure to work with and has good answers for all conceivable questions. This is a nonprofit organization focused on the goal of getting solar panels onto as many roofs as possible, which makes working with them more fun and less stressful than with a regular profit-oriented contractor since you don't have to worry about differing motivations between contractor and client. Sunwork is recommended absolutely without reservation.

Great experience from top to bottom. I researched installing solar PV panels for a long time and the economics did not pencil out for me. I was not ready to DIY on a project this big. Enter Sunwork and their unusual business model aimed at low-energy consumers and non-profits. Communication is very good. There is no sales push, just all the information you could possibly want. I recommend these folks without reservation.
