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.
So far in 2026, the Metropolitan Region has added 16.1 MW of capacity, followed by Valparaíso with 8.7 MW, O’Higgins with 6.6 MW, Maule with 5.4 MW, and Ñuble with 3.4 MW. May recorded 10.3 MW of new capacity, below January (14.6 MW) and March (13.6 MW).
The report also includes data on storage linked to Net Billing systems. Cumulative declared battery energy storage system (BESS) capacity totals 201 kWh as of May 31, 2026, distributed across projects reported in 2024, 2025, and 2026. The Metropolitan Region accounts for 75 kWh, followed by Maule with 32 kWh and Ñuble with 28 kWh.
By financing type, the report attributes 421.1 MW to private projects, far exceeding all other categories. By consumption sector, agriculture leads with 208.3 MW, followed by residential with 124.5 MW, industrial with 74.5 MW, and commercial with 56.5 MW.
