Tuesday Lancaster voters on a 113-to-8 vote gave the select board permission to borrow up to $320,000 for solar arrays that would generate 121 kilowatts.
However, rebates could lower the cost to about $243,000, town officials have said.
Town officials predict going solar will save the town about $25,000 a year. That’s about 25 percent of the town’s total energy cost.
It was estimated it could take about 15 years to pay for the equipment, but one town official said if the rebates come through and drop the price to about $243,000 it would be much quicker.
A town official said it is hoped the system will be generating electricity by this Fall.
