摘要：The article deals with the utilizing of solar energy by the means of concentric trough collector based on own design. It focuses on achieving optimal position of the trough with respect to incident radiation during its operation. Due to the collector virtual sun tracking system, which was proved to be ineffective and could not achieve the desired results, the optimum position had to be maintained by manual control of rotation. The measurement of the angle of rotation of the concentric trough is realized using the ARDUINO electronic platform, for which the program was created in the software ARDUINO (IDE) 1.8.4.
