Many countries have installed research bases in the Antarctic to conduct various studies in this very special landscape and its unique climate. Temperatures below
-89 °C, winds over 200 km/h, extreme variances in hours of sunlight, with up to 16 hours in the summer and only two during winter, pose tremendous challenges for both research teams and equipment. PV connectors from Stäubli are part of a demanding new field of application: installing solar power in the Antarctic.

Promoting the expansion of renewables

The Uruguayan government is a strong advocate for the integration of renewables and following a ten-year program to reduce its dependency on fossil fuels. 97% of the electricity now comes from hydroelectric, solar, wind and biomass. The country has been maintaining a research base in the Antarctic for over 30 years. The Artigas base, opened in 1984, is home to ten research scientists and 15 crew members in summer.

The base was traditionally
