DUXBURY (AP) - Crossett Brook Middle School in Duxbury now has Vermont's largest school solar array.

Gov. Peter Shumlin and others threw the switch on the system Thursday, inaugurating the 157-kilowatt solar array, the largest such system at a school in the state.

Shumlin was joined by state and local officials and representatives of the solar power company the installed the array, SunCommon, and Green Mountain Power, Vermont's largest electric utility.

The 480-panel array can produce enough electricity for about 30 homes and it's expected to save the school thousands of dollars in electricity costs.
