A sun score is a crucial metric that evaluates a property’s suitability for solar panel installation. Ranging from 0 to 100, a higher sun score indicates better conditions for generating solar energy. This score is determined by factors such as the roof’s orientation, slope, and size, the amount of sunlight received, local climate, and electricity rates. For homeowners considering solar panels, a sun score of 70 or above is generally considered optimal, meaning the property has strong potential for solar power production. Even if your score is lower, understanding how much sun your house gets and possible adjustments can improve solar efficiency. Real estate platforms like Zillow also display sun scores, helping buyers and homeowners make informed decisions about investing in solar energy.
