Abstract
The article presents a methodology for analysis of power output the photovoltaic system depending on geometry of solar contractor mirrors. The concentrator directs the solar radiation reflected from mirrors onto photovoltaic surface, which increases the efficiency of solar panels. An essential element of the concentrator system is a two-axis tracking system which tracks the apparent position of the Sun on the celestial sphere. The analysis of luminance stream falling on photovoltaic surface depending on inclination angle of the concentrator mirrors made of electrochemically polished steel and resolution of step tracking system was performed. The technical light properties of the concentrator mirrors were determined using the BRDF function. The results of analysis were used to calculate the voltage, current and power output of photovoltaic system.
