hunter63 -- Wisconsin, currently, seems to be discouraging grid-tied solar via legislation and policy. Too, bad. That said, you have a great resource not too far away: the Midwest Renewable Energy Association (MREA). They are located just east of Stevens Point. Hands down, they are one of (if not THE) best training, support, and resource non-profit in the USA for all things related to renewable energy. Their web address is:
https://www.midwestrenew.org/ . If you've never attended their annual renewable energy fair, it's a must-do event -- mid-June, every year.
