Solar power can feel out of reach. Upfront costs are usually considerable and you need a sunny roof or open space where you can put the panels. Community solar projects make it more accessible, by allowing ratepayers to buy shares in an installation that’s financed and operated by a group of investors. Utilities around the state, including Seattle City Light and Avista, offer them. Now, Snohomish County PUD is getting in on the game — in a big way.
