title: Results of Long-Term Operation of Solar Thermal Plants in Russia
abstract: The total capacity of solar heat supply systems in Russia in 2020 reached 70 MW (87 500 m2). Thirty solar thermal plants (STPs) with a total area of 1400 m2 (100%) were built in 2019–2020, including 21 plants with flat solar collectors (SCs) with an area of 1300 m2 (92.9%) and 9 STPs with vacuum tubular SCs (100 m2, 7.1%). Based on their purpose, 25 of these STPs with an area of 1150 m2 worked for hot water supply, one plant with an area of 200 m2 for heating, one with an area of 12 m2 for heati
