Residential Solar Investment Program (RSIP) Enrollment

Through the Residential Solar Investment Program (RSIP), the Connecticut Green Bank, in partnership with a network of contractors and inspectors, helped more than 46,300 households access solar energy since 2012, surpassing the statutory target of 350 MW (reaching 378 MW) one year ahead of the December 2022 deadline.

Highlights

$1.43B total investment
$156M total incentive
$0.41/W average incentive
$3.79/W installed cost

How it works

RSIP provided rebates and incentives to make rooftop solar more affordable for homeowners.
When panels produce electricity, they save money and create Solar Home Renewable Energy Credits (SHRECs).
Utilities entered into Master Purchase Agreements (MPAs) with the Green bank to buy SHRECs to comply with policy programs.
Green bonds are created via SHREC revenue and purchased by both individual and institutional buyers.
Revenue from MPAs and Green Bonds support RSIP incentives and cover administrative costs.

This dataset is an anonymized comprehensive listing of all approved and completed projects supported by the RSIP. It contains information on system costs, sizes, participating contractors, and other details gathered during the RSIP.
