Question 1

Did these co-op arrays make my bill go up or down?

Accepted Answer

Honestly, neither by much on their own. A megawatt or two of solar is a small slice of a cooperative's total supply, so the effect on any one monthly bill is modest. The larger value is price stability over the length of the contract.

Question 2

Can I buy into a community solar array through my co-op?

Accepted Answer

It depends entirely on your co-op. Some member cooperatives offer a community solar subscription where you pay for a share of an array's output; others do not. Call your local cooperative and ask what is open.

Question 3

Why are these so much smaller than the new solar farms?

Accepted Answer

They connect to local distribution lines rather than the high voltage transmission grid, which caps their practical size at a megawatt or two per site. The big farms connect to transmission and can run into the hundreds of megawatts.

Question 4

Does Wisconsin snow make solar pointless?

Accepted Answer

No, it just lowers winter output. Panels still produce on cold clear days, and snow usually slides off tilted modules within a day or two. The annual total matters far more than any single snowy week.
