The largest solar-electric generator in Minnesota has flipped on the switch -- the latest sign of a banner year for solar installations.

Renewable power developer Ecos Energy said 7,040 solar panels outside of Slayton, Minn., began producing power Friday after being connected to Xcel Energy's distribution system. The solar array is the largest in the state, with 2 megawatts of output, the equivalent of the power used by 250 homes.
