Maryland has launched a pilot program that will allow anyone to power their home with solar panels — even if they are renters, condo-dwellers or live in the shade of trees. Solar developers are looking for hundreds of residents to subscribe to six power projects planned across the state, including recently announced sites in Owings Mills and Westminster. Their offers include discounts off standard electric rates.The developers need a critical mass of customers who are willing to buy the projects’ electricity before they can move forward with plans to install solar panels on about 80 acres, altogether. Under state rules, the customer base must include low- and moderate-income residents.
