18 What makes a home good for solar? Do I have a south ish facing roof or location? East & West applications increasingly common Is my roof unshaded? Is my roof structurally sound? Do I expect my roof to last at least 10 more years? Is my home energy efficient? A 2017 MadiSUN installation by Midwest Solar Power Do you want to drive on sunshine?

19 Wisconsin s First Solar Subdivision to Rise in New Berlin - 34 residences - Solar on every roof - May 2017 groundbreaking
