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.
