Rooftop Solar Photovoltaic Systems Account for 20% of Puerto Rico’s Capacity Mix

Rooftop solar photovoltaic systems now represent 20% of Puerto Rico’s total generating capacity, reaching 1,456 MW by the end of 2025 and becoming the island’s second-largest capacity source after petroleum liquids. Over the past decade, rooftop solar installations accounted for 81% of new capacity additions, driven by widespread adoption in homes and businesses, with nearly 192,000 systems installed. Alongside solar, distributed battery storage has expanded significantly, with over 171,000 units providing 2,864 MWh of energy capacity and forming virtual power plants that support grid stability through programs like LUMA’s Customer Battery Energy Sharing.
