residential solar and battery storage installs from the Connecticut Green Bank's incentive programs on data.ct.gov, each naming its installing contractor. program ess (default) is Energy Storage Solutions: battery projects from 2022 to now, including projects still in progress, reloaded monthly. program rsip is the closed Residential Solar Investment Program: about 48,000 rooftop solar installs approved 2004-2021 and completed through February 2024. Filter by town, ZIP, contractor, ESS stage, sector, completed, enrolled or energized date window, ESS last-change date, minimum kW and pre-existing batteries; ESS batteries transferred from the ConnectedSolutions program, which name no installer, are left out unless include_transfers is true. Sort by newest completion (default), newest enrolment, latest change, size or cost. Each record has the program, ESS project id and stage, contractor, town, ZIP, county, utility, enrolled, approved, energized and completed dates, solar and battery size, battery models, cost, incentive, financing, third-party owner, source_url and licence. No street address or customer name is published. An empty page is a valid result. - Instructions: Use to see who installed solar or batteries in a Connecticut town or ZIP, list a contractor's installs, or monitor new battery projects: poll with enrolled_since (new applications) or updated_since with sort updated_desc (any change), knowing the dataset reloads about monthly. These are incentive enrolments, not building permits. Rank installers with contractor_activity. - Cost: 5 credits per call - Capability file: [Search installations](https://firecrawl.dev/alexandria/agents/providers/data-ct-gov/building-permits/search_installations) Accepted options: - `completed_since` (string): Only projects completed on or after this day, YYYY-MM-DD. Pattern: ^[0-9]{4}-[0-9]{2}-[0-9]{2}$. Example: `` - `completed_until` (string): Only projects completed on or before this day, YYYY-MM-DD. Pattern: ^[0-9]{4}-[0-9]{2}-[0-9]{2}$. Example: `` - `contractor` (string): Case-insensitive substring of the contractor company (earthlight, sunrun, trinity). Example: `` - `cursor` (string): next_cursor from the previous page; repeat the same filters with it. Pattern: ^[0-9]+$. Example: `` - `energized_since` (string): ESS only: batteries energized (in service) on or after this day, YYYY-MM-DD. Pattern: ^[0-9]{4}-[0-9]{2}-[0-9]{2}$. Example: `` - `energized_until` (string): ESS only: batteries energized on or before this day, YYYY-MM-DD. Pattern: ^[0-9]{4}-[0-9]{2}-[0-9]{2}$. Example: `` - `enrolled_since` (string): Only projects that enrolled on or after this day (ESS application submitted; RSIP approval), YYYY-MM-DD. Use it to poll for new projects. Pattern: ^[0-9]{4}-[0-9]{2}-[0-9]{2}$. Example: `` - `enrolled_until` (string): Only projects that enrolled on or before this day, YYYY-MM-DD. Pattern: ^[0-9]{4}-[0-9]{2}-[0-9]{2}$. Example: `` - `include_transfers` (boolean): ESS only: also return the about 330 batteries transferred from the utilities' ConnectedSolutions program, which name that program instead of an installer (their contractor is null). Left out by default. Example: `false` - `limit` (number): Rows per page. Example: `25` - `min_size_kw` (number): Minimum size in kW: solar kW for rsip, battery kW for ess. Example: `10` - `municipality` (string): Connecticut town, exact and case-insensitive (Glastonbury, West Hartford). For RSIP the postal village also matches (Mystic, Niantic). Example: `` - `pre_existing` (boolean): ESS only: true keeps batteries that were already installed when they enrolled (installers that enroll after energizing, ConnectedSolutions transfers); false keeps systems installed under the program. Omit for both. Example: `false` - `program` (string): ess (default): Energy Storage Solutions battery projects, 2022 to now, including projects in progress. rsip: the closed Residential Solar Investment Program, rooftop solar approved 2004-2021 and completed through February 2024. Example: `ess` - `sector` (string): residential, or commercial for ESS C&I projects. RSIP is residential only. Example: `residential` - `sort` (string): completed_desc: newest completion first, projects in progress last; enrolled_desc: newest enrollment first; updated_desc (ESS only): most recently changed first; size_desc: largest kW first; cost_desc: most expensive first. Example: `completed_desc` - `status` (string): ESS only: case-insensitive substring of the project stage or status (complete, installation, submitted, pending). Example: `` - `updated_since` (string): ESS only: YYYY-MM-DD or RFC 3339 timestamp; projects the program system changed on or after that day (last_updated, compared by day because it is published without a zone). Socrata's :updated_at is not used: each monthly load stamps every row alike. Pattern: ^[0-9]{4}-[0-9]{2}-[0-9]{2}([Tt ][0-9]{2}:[0-9]{2}:[0-9]{2}(\.[0-9]+)?([Zz]|[+-][0-9]{2}:[0-9]{2}))?$. Example: `` - `zip` (string): Five-digit ZIP of the install, e.g. 06033. Pattern: ^[0-9]{5}$.
