Connecticut Solar and Battery Installs (data.ct.gov)

Connecticut residential solar and battery storage installs from the state open data portal data.ct.gov, as published by the Connecticut Green Bank, each naming the contractor that installed it. Energy Storage Solutions (ESS, dataset uy2c-bbdw): about 1,900 battery projects from 2022 to now, reloaded monthly, from application to completion, with stage, town, ZIP, approximate coordinates, utility, enrolment, approval, energized and completion dates, battery kW and kWh, paired solar kW, battery models, contract and battery cost, incentive and third-party owner. Residential Solar Investment Program (RSIP, dataset fvw8-89kt): about 48,000 rooftop solar installs approved 2004-2021 and completed through February 2024 (the program is closed), with town, ZIP, kW, cost, incentive, financing and third-party owner. Search installs by town, ZIP, contractor, date window and size, poll ESS for new or changed projects, and rank installers by installs or kW. These are incentive program enrolments, not building permits; no street addresses or customer names are published. Both datasets are Public Domain: every response and record carries its licence, attribution and source URL.
