Founder Jerry Marizza explains the idea.
"Here's how it works: For $1,050, an investor gets a 25-year lease on a photovoltaic panel set up on United Power's land. The co-op takes care of installation, insurance and maintenance. ("We'll squeegee it once a month," Mr. Marizza promises.) Investors can visit their panels any time and track their energy output online. Each month, they get credit on their bill for that amount."
