The Southbury Public Library will throw the switch on its 6 kilowatt solar system on Saturday.
Scotland energy firm Renewable Resources constructed the array for the library at a cost of $23,280. Renewable Resources has offices in Stamford.
The 24 solar panels are expected to produce 7,733 kilowatt hours of electricity. The system has a life expectancy of 25 years.
The ceremony for the array is set for 12:30 p.m.
