Join ReVision Energy Project Manager Ryan Herz on Wednesday, July 28, from 5:30-7:30 p.m. to learn about the grid-tied solar electric system recently installed at the town’s sand shed located at 71 South Mountain Valley Highway (Route 220), just behind the fire station.

The open house will focus on the eight-kilowatt grid-tied solar electric system now up and running at the sand shed, including information regarding its annual electrical production, carbon offsets and how the system works.

In addition to learning about the solar electric system, guests will also have the opportunity to hear from town representatives regarding the project funding, 90 percent of which came from an Efficiency Maine grant. The eight-kilowatt system will offset more than 90 percent of the town’s current electrical usage at five town-owned buildings.

Unlike battery-based systems, grid-tied solar electricity systems use the existing electrical grid to store any excess power created on site. Utility companies in Maine, under net-billing law, are required to credit any excess production (month by month) to the account owner for up to 12 months.

Guests are encouraged to come by with questions and to sign up for a solar site evaluation while at the open house.

For more information, visit or call the town of Montville at 589-4171.
