Renewables in MN

Well, it's been a busy year in the world of renewable energy systems in the government market here in Minnesota. I've designed and bid almost 200 kW of projects, with most of it came online in the last quarter. I have been hearing some about some poor decisions being made by other design professionals in this area including the design of a solar thermal system without the use of glycol to protect the piping and system. We had successful bids on a 25 kW system for Three Rivers Park and a 30 panel solar thermal system for the Audubon Nature Center in Sandstone MN.
