Enphase Microinverter and Iron Ridge Rail Solar Installation DIY. 225w Scheuten Panels (25 yr warranty) which I purchased online for abt $200 per panel free shipping at Solar Systems USA. The Inverters cost around $140-150 per inverter. Rails cost another $300 or so total. Given the great prices, and user installed, my ROI is less than 18 months. This vid will show you how to install the rails, panels, and inverters yourself. This project took me a full weekend and had a lot of fun in process figuring out. But if you can put together an IKEA dresser, you can do full solar/rail installation. Granted, you should have your final wiring double checked by licensed electrician, given the obvious danger of electricity.
