Everything you need to know about plug-in balcony solar in Rhode Island: legal status, tracked bills, statutory wattage limits, utility interconnection rules, and expected monthly solar production.
Current Disposition: Balcony solar bill failed
Rhode Island has no law addressing balcony solar. Its 2026 portable-solar bills, S 2359 and H 7269, would exempt certified devices from interconnection and net-metering requirements. The Senate committee held S 2359 for further study on April 15, 2026. H 7269 passed the House as Substitute A on June 9, 2026 and was referred to Senate Environment and Agriculture, and has had no further action.
