Much of the Russian territory is situated in climates where winter temperature could reach -40°C. The need for energy supply of these regions in accordance with the program “The Energy Strategy of Russia for the Period of up to 2020” imposes certain requirements, such as environmental friendliness, safety, autonomy, low operating costs. These requirements are met by renewable energy sources, in particular, solar modules. To evaluate the effect of low temperatures on their parameters, long-term test is being conducted at temperature of -50°C in a special environmental chamber in the R&D Center.
Also, since June 2013 in Yakutsk on the roof of the building of natural science faculty of North-Eastern Federal University R&D specialists have installed photovoltaic systems based on a-Si:H/mc-Si:H and crystalline Si for tests in real operating conditions.
