House Bill 904, introduced in Massachusetts on April 23, 2025, aims to address the growing concern over the disposal and management of end-of-life solar photovoltaic panels and energy storage system batteries. As the state continues to expand its renewable energy initiatives, the bill seeks to establish a comprehensive plan for the effective collection, transportation, reuse, refurbishment, recycling, and disposal of these materials.

Key provisions of the bill include the development of infrastructure necessary for managing solar and battery waste, an assessment of emerging recycling technologies, and the potential creation of model agreements between solar companies and municipalities. Additionally, the bill proposes evaluating the need for stewardship programs that would require manufacturers and installers to contribute to recycling efforts, including the establishment of fees to support these initiatives.

The bill has sparked notable debates among stakeholders. Proponents argue that it is essential for promoting sustainability and reducing environmental impacts associated with solar energy systems. Critics, however, express concerns about the potential costs and regulatory burdens that could arise from implementing such programs.

Economically, the bill could lead to the creation of new jobs in the recycling and waste management sectors, while socially, it emphasizes the importance of responsible environmental practices as Massachusetts transitions to a greener energy landscape. The political implications are significant as well, as the bill reflects a growing commitment to renewable energy and environmental stewardship in state policy.

The Massachusetts Department of Energy Resources is tasked with filing a report by July 1, 2026, detailing the status of the statewide management plan, including recommendations for regulations and cost estimates. This timeline indicates a proactive approach to addressing the challenges posed by solar waste, positioning Massachusetts as a leader in sustainable energy practices.

As the bill progresses through the legislative process, its outcomes could set important precedents for other states grappling with similar issues in the renewable energy sector.
