Abstract: The finiteness of fossil fuels, environmental damage from their combustion and increasing production costs promote acceleration of the global energy transfer to renewable energy sources and development of eco-friendly and resource-saving technologies. The vast Russian territory is permafrost or areas with seasonally frozen soils. Renewable energy sources are relevant for such territories, especially solar energy as the most affordable. Purpose: The aim is to improve the hardware-software complex for energy saving and safe year-round operation of the hybrid solar hot water supply system. Methodology: An experimental-industrial hybrid solar hot water supply system with four evacuated tubular collectors and a solar power plant with an installed capacity of 5 kW is used in the village Kaftanchikovo, Tomsk region, in the production workshop of NPO VEST. Research findings: The full-scale experimental test is conducted for the hardware-software complex, the ability to ensure safe operation of the system with an energy-saving effect at night at temperatures below the freezing point of the coolant in the hydraulic circuit of the collectors is shown. Value: It is shown that the use of the proposed hardware-software complex for a hybrid solar system with four evacuated collectors allows to minimize additional heat losses, which do not exceed 55.8 % of the heat loss of water passing through the walls of the storage tank.
