“I am semi retired from installing solar systems since 2006. Have installed grid tied, off grid and solar hot water in those years and now let the younger people do the installs and I do repairs. I offered my services to the Olson Brothers when I found out they were getting started in 2017. Since then, we have had a great working relationship. They have been great to communicate with and great with their customer service. I am honored to have been an influence in their start up.” – Rich Bannen – Master Electrician (Prairie du Chien WI)
