The global "green" energy trend is also rapidly developing in Azerbaijan, although the country's economy is still mainly dependent on oil and gas production. Analysis of the prospects for the efficient use of renewable energy sources is a topical issue in terms of the implementation of the decree on the transformation of the Karabakh zone of Azerbaijan into a "green" energy zone. The article examines the prospects of applying solar vacuum tube panels for the climatic parameters of the Gubadli region of Karabakh. The thermal energy production capacity of the solar panels was evaluated by the "Helios-house" program. The results show that the number of Hevelius SCM-12 180-58 panels placed in the area of 50 m² in Gubadli region should be 12 with the efficiency 70%, the heat loss coefficient of vacuum tubes is 0.5W/m², the average amount of thermal energy received by solar radiation is 1625 kW/m2 and the total thermal energy production is 14938 kWhr/year. The proposed evaluation methodology can be applied to any region of Azerbaijan.
