Customers are paying a lot for electricity these days. Some are thinking how great it would be to take advantage of solar energy floating free from the sky. But would solar even work for their home?

People with low and moderate incomes can have solar installed and connected free. We talk with Eli Allen, Civic Works’ senior program director, and with John DeHuitta, a Civic works trainee.
