¡ 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?

¡ Do you want to “drive on sunshine?”A 2017 MadiSUN installation by Midwest Solar Power

RENEW WISCONSIN

Solar homes sold 20% faster and for 17% more than the equivalent non-solar homes across several subdivisions (construction by different builders).

NREL (National Renewable Energy Laboratory)

In a study across six states, Berkeley National Lab found that home buyers will pay a premium for solar homes.
