The service at GoGreenSolar.com is great. The company is very nice, and has a very user friendly website. I never hire a company that doesn't have a website. Before choosing a company, I checked around for the best prices and the only item that was out of range for this company were the batteries. With that said, in speaking to the GoGreenSolar.com service person, they were able to lower prices substantially on batteries to almost match all competitors.
In addition, I didn't pay sales tax on any purchases through them. I was able to redo the solar panels on my entire vacation home and was very pleased.
