Use of Portable Solar Generation Devices
Latest Action: January 26, 2026
Everything you need to know about plug-in balcony solar in New Mexico: legal status, tracked bills, statutory wattage limits, utility interconnection rules, and expected monthly solar production.
Current Disposition: Balcony solar bill failed
New Mexico Senate Bill 157 would create a portable solar generation device category for movable photovoltaic devices up to 1,920 watts connected through a 120 V outlet, with anti-islanding, electrical-code, and nationally recognized testing-laboratory requirements. It would exempt qualifying devices from interconnection and net-metering requirements and bar utility approval, registration, and device-related fees. The official legislative record lists the bill as died and postponed indefinitely, so the proposal is not law.
