Rooftop solar photovoltaic systems account for 20% of Puerto Rico’s capacity mix ›

Rooftop solar generating capacity in Puerto Rico totaled 1,456 megawatts (MW) at the end of 2025, 20% of the overall capacity mix. Rooftop solar capacity has increased faster than other sources over the past decade. Between 2016 and 2025 rooftop solar installations accounted for 81% of the new generating capacity in Puerto Rico, according to data from our Electric Power Monthly and Puerto Rico Energy Bureau’s (PREB) Quarterly Report on System Data. In 2025, rooftop solar became the second-largest capacity source, after petroleum liquids capacity (3,671 MW), and surpassed natural gas capacity (1,391 MW). More
