Even for residents in gloomy states, solar panels can greatly reduce power costs, let alone carbon footprints. In fact, because of solar power success in Germany, the state of Washington (a state that receives overcast days 65% of the year) decided to copy Germany’s solar financial incentive programs. Let’s take a closer look at some factors to consider before making a purchase decision.
