Solar - Amends and adds to existing law to exempt portable solar generators from public utilities
Latest Action: April 2, 2026
Everything you need to know about plug-in balcony solar in Idaho: legal status, tracked bills, statutory wattage limits, utility interconnection rules, and expected monthly solar production.
Current Disposition: Balcony solar bill failed
Idaho has no law addressing balcony solar. House Bill 612 would have exempted portable solar generators from public-utility regulation. It was referred to House State Affairs on February 11, 2026, saw no further action, and died when the 2026 session adjourned sine die on April 2, 2026.
