Representatives of a state program promoting the use of solar energy will hold an informational session for residents at 7 p.m. Wednesday in the Brookline High auditorium. Brookline was one of 10 communities selected by the Massachusetts Clean Energy Center and the state Department of Energy Resources for this year’s Solarize Massachusetts effort, which encourages the installation of small-scale photovoltaic projects in homes and businesses through discounts and other incentives. “Solar coaches’’ Werner Lohe and Keske Toyofuku are spearheading the local effort to educate people about solar energy and promote the program’s model, which offers more savings as more residents and businesses install solar panels. Lohe, who is also a member of the town’s Climate Action Committee and Climate Action Brookline, said the goal is to get at least 150 homeowners, as well as some businesses, signed up for the program by the Sept. 30 deadline. SolarFlair Energy Inc., which has been chosen as Solarize Brookline’s official installation company, will also participate in the question and answer session, and register residents for a free assessment of their property’s suitability for solar panels.
