Basok, B.I. Pasichnyk, P.O. Goncharuk, S.М. Solar energy is an important component of the energy potential of renewable energy sources in Ukraine, on the basis of which the consumption of fossil fuels is reduced and the energy independence of the country is increased. Solar heat supply systems have greater energy efficiency than electric ones, so their development is an important urgent task. The central element of any solar system is a collector of solar energy that absorbs radiation and transmits it to a coolant or direct heating object. One of the ways of development of solar thermal heaters is the use of new materials for the manufacture of solar radiation absorbers, which significantly expands the possibility of using nozzle and porous capillary materials, in contrast to liquid solar collectors. It is advisable to use textile materials for the manufacture of absorbers, which allows to reduce the cost of solar energy collectors, as well as to significantly improve their installation and operational characteristics. In particular, the use of carbon graphite knitted fabric makes it possible to apply direct heating of the solar energy absorber with electric current based on certain electrical engineering solutions. At the same time, you can take advantage of the scientific developments in the production of various flexible heaters (electric heaters, medical blankets, etc.). In this way, it will be possible to combine two mandatory elements of solar heat supply systems, a solar energy collector and an additional heat source. The article presents the defining electrotechnical characteristic for a product of this type, namely the specific electrical resistance of the fabric. The paper presents the schematic diagram of the experimental stand and describes the methodology of conducting experimental research. Also given are the results of an experimental study of the specific electrical resistance of carbon graphite knitted fabric VTP-1, produced in non-experimental production at the Institute of Problems of Materials Science of the National Academy of Sciences of Ukraine named after I.M. Frantsevich, which is used as an absorbing element in an air thermal solar collector. В статті приведено експериментальне дослідження електротехнічних характеристик вуглеграфітового трикотажного полотна, що використане у якості поглинаючого елемента в сонячному тепловому повітряному колекторі. Поглинаюча здатність матеріалу та коефіцієнт тепловіддачі до омиваючого повітря встановлені в попередніх роботах і виявилися не гіршими за металеві аналоги. В дослідженні розглянуто можливість догріву поглинаючого елемента шляхом пропускання електричного струму.
