The Board of Selectmen on April 17 heard the final words about an ambitious solar electricity-generating plan that could save the town as much as $2.3 million over the next 20 years. The plan is to install solar panels on the roofs at Miller-Driscoll School, Middlebrook School and possibly Wilton High School. The solar arrays would be owned, installed and maintained by a solar vendor who would sell solar-generated electricity to the town for 20 years at fixed rates that are lower than current and expected electric rates. The hearing was conducted at town hall and drew no comments. A vendor will be selected based on bid price, expertise and financial viability, according to the presentation materials. The town would have the option to purchase the arrays at the end of the 20 years or have the equipment removed at the vendor's expense. If need be, equipment could be removed and reinstalled to allow for roof replacements. The Board of Selectmen is expected to take action on the plan on May 1. If approved, installations will take place at Miller-Driscoll and Middlebrook this summer. The roofs would be generating solar power by October. Installation at the high school, which already has solar panels, will be discussed at a future date.
