Abstract
The article presents a tracking system controller that tracks apparent position of the Sun on celestial sphere. The device does not require any operating by user. Applying the GPS module, gyroscope, magnetometer and accelerometer ensures the autonomy of device. In controller was implemented authorial algorithm which on the basis of collected data automatically selects appropriate value of inclination angle the photovoltaic surface in relation to direction of incidence solar radiation and resolution step tracking system. The efficiency analysis of the presented system was performed depending on sunlight conditions. Then, the device was compared with the analogical solution that does not use the authorial algorithm. The results of simulations showed that this tracking controller allows to increase in the power output of photovoltaic panels from 4% to 7%.
