Argentina is intensifying its solar energy development through advanced research at CNEA and a significant rise in large-scale photovoltaic capacity, supported by emerging private sector projects poised to enhance the national clean energy matrix by 2027. The integration of space-grade photovoltaic technologies and expanding terrestrial solar parks marks a dual-front growth trajectory with implications for both technological innovation and energy supply diversification.
The Comisión Nacional de Energía Atómica (CNEA), via its Department of Solar Energy based in the Centro Atómico Constituyentes, operates specialized laboratories for fabricating and testing photovoltaic devices suited for terrestrial and space applications. These facilities include a controlled clean room environment and equipment such as solar simulators and radiation damage testing lines, enabling robust performance evaluation of solar cells for Argentine satellites. Historically, CNEA developed solar panels for the SAC-A satellite (1998), the Aquarius/SAC-D mission, and the SAOCOM earth observation satellites. Currently, it is finalizing solar panels for the SABIA-Mar 1 satellite scheduled for launch next year. The department also produces solar position sensors, aiding satellite orientation relative to the sun, and supplies panels for private nanosatellite companies since 2012.
On the terrestrial front, Argentina’s solar capacity has expanded rapidly, now featuring 76 active solar parks totaling over 2,000 MW, quadrupling installed capacity in five years. Concentration is highest in provinces with optimal solar irradiation such as San Juan, San Luis, Catamarca, and Mendoza. Notable projects include the 315 MW Cauchari Solar complex in Jujuy and the 180 MW Anchoris Solar Park in Mendoza, with continued growth supported by national programs like RenovAr and market mechanisms such as MATER.
Private developers are actively advancing capacity and technological integration. Ambiente y Energía, a key market player, plans to develop 400 MW of solar projects between 2026 and 2027, including 100 MW of proprietary generation. The company recently secured dispatch-priority contracts under MATER and is moving forward with EPC projects and battery storage integration to enhance grid stability and energy continuity. Despite infrastructure and regulatory challenges, the momentum in Argentina’s solar sector points to sustained expansion and deeper adoption of renewable technologies across both specialized and commercial segments.
