Gogreen was great when I originally set up and purchased my system. After a year, over half of my inverters stopped working. It has been over a month, and I still have not got my replacements. I was told they were shipping one week, the out of stock the next. I’ve been paying my solar loan payments and having to pay an electric bill...all during the hottest month of the year! If you purchase a system, hopefully you want need to replace any parts.
