An Act increasing solar rooftop energy

This bill mandates that new residential and commercial buildings in Massachusetts be constructed with solar energy systems to meet specific electricity needs. It requires single-family homes to generate at least 80% of their average annual electricity usage, while multi-family and commercial buildings must install solar systems with battery storage based on factors like roof size and building type. The legislation also directs state officials to create rules ensuring new buildings have the structural capacity and electrical infrastructure necessary to support rooftop solar installations. Additionally, the bill allows for exemptions if a building lacks sufficient solar potential or if alternative renewable energy systems are used instead.
