WISCONSIN SOLAR POWERED HOMES: EQUIPMENT & APPLICATIONS
Grid-tied Solar Electric System Utility supplies any electricity not produced by panels (at night, cloudy days) Least expensive System size (in kw) determined by Your electric use Your property
Components of a PV System Panels or Modules make up an Array Converts sunlight into electricity No moving parts Warrantied for 25 years Designed to handle golf ball-sized hail Snow melts off due to roof pitch and dark color Inverter Converts DC electricity from solar panels AC electricity used by appliances Warrantied for 10 years Connects to monitoring equipment Slide courtesy of MREA
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?
Wisconsin s First Solar Subdivision to Rise in New Berlin - 34 residences - Solar on every roof - May 2017 groundbreaking

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.
