    "notes": "House passed H.5175 on 26 February 2026, 128-27, Roll Call No. 141. Senate struck the text and substituted S.3143 on 1 July 2026, reprinted as S.3166, and passed it 32-8, Roll Call #205. House non-concurred on 16 July 2026; conference committee appointed the same day, Cusack-Michlewitz-Jones for the House and Barrett-Creem-Tarr for the Senate. No action since. The Legislature's own full-text search returns S.3166 as the only document in the 194th General Court containing the phrase 'plug-in solar', so the plug-in solar language sits in the Senate version that the House has not accepted. The section itself has not been read; no wattage limit or certification standard is recorded here. Verified against malegislature.gov on 18 August 2026."
