In 2025, rooftop solar capacity in Puerto Rico reached 1.5 GW, surpassing natural gas as the second-largest generation source, driven by electricity reliability issues. Distributed generation resources, particularly rooftop solar with battery systems, have seen significant growth. LUMA Energy, the island's grid operator, is working to transform and stabilize the grid. Distributed battery storage has also increased, reaching a total energy capacity of 2,864 megawatt hours. Despite setbacks like Hurricane Maria, rooftop solar generation has steadily increased, contributing to Puerto Rico's total generation capacity exceeding 7 GW.
