The country has accumulated 502.9 MW of declared capacity across 41,986 facilities under the distributed generation scheme, according to new figures from Chilean PV association Acesol.
Chile reached 502.9 MW of operational capacity under the Net Billing scheme as of May 31, 2026, according to new figures from local solar association Acesol, based on data from the country’s Superintendency of Electricity and Fuels (SEC). Of this total, 501.9 MW corresponds to solar capacity, underscoring the near-total dominance of photovoltaic technology in the grid-connected self-consumption segment.
The report records 41,986 cumulative installations since 2015, of which 41,962 are solar. In 2026 alone, up to May, an additional 56.1 MW and 3,913 new installations were added.
By region, the Metropolitan Region leads with 146.3 MW of cumulative declared capacity, followed by Valparaíso with 74.7 MW, Maule with 60.4 MW, and O’Higgins with 60 MW. In terms of installed systems, the Metropolitan Region also ranks first with 14,723 installations, ahead of Valparaíso (4,852), Maule (3,793), and Biobío (3,306).
Most cumulative capacity is concentrated in the 200 kW–300 kW range, which accounts for 193.7 MW. However, the majority of installations are small-scale: the 0 kW–10 kW segment alone represents 38,187 systems out of the total 41,986.
