Solarize Connecticut and Clean Energy Finance and Investment Authority will host an open house at a Fairfield home on Saturday, Nov. 10, to show a photovoltaic system installed through the Solarize Fairfield program.

The event will take place from 1 to 3 p.m. at the home of Larry and Sharon Kaley, 1162 Jennings Road, during the final phase of installation of a 5.28-kilowatt system, according to a release from residential solar installer Astrum Solar.

The system, once operational, will offset 100 percent of the home's electricity and will virtually eliminate their $1,450 annual electric bill, marking a savings of $120 each month, the release states.

The couple chose the Solarize Fairfield purchase option at a net cost of $6,700, with a four-year payback. When enough neighbors join them, their costs will go down to $5,600 and shorten their payback by a year, the release states.

If they had chosen the pay-as-you-go option with no up-front cost, their savings would have been $80 per month, versus $120 per month.

Solarize Connecticut, developed by the authority, is a pilot program designed to encourage adoption of residential solar power by offering a tiered pricing structure that provides increased savings to homeowners as more people in the community go solar.

Representatives from Solarize Fairfield, the authority and Astrum Solar will be available to answer questions about both the installation and the program on Saturday.

For information on the open house, call Larry Kaley, chairman of Fairfield's Clean Energy Task Force and the local Earth Day Committee, at 203-581-0006.
