Description
Summary:The development and research of solar photovoltaic–thermal systems is aimed to improve the efficiency of using solar energy when it is converted into consumer energy formats. The use of concentrated solar radiation can increase the efficiency of photovoltaic conversion and reduce its cost by replacing solar cells with concentrating structural elements. At the output of the concentration photovoltaic–thermal (CPVT) installation, photovoltaic and thermal energy is obtained. In this paper, the output parameters of the photovoltaic part of the developing CPVT system are determined. The problem is considered in the context of the sun–tracking system operation, which provides a constant orientation of the input window plane of the concentrator perpendicular towards direct solar radiation during the entire time of sunshine. In this regard we consider the change of the orientation angle—azimuth and elevation angle of the solar disk—for the Moscow region. Kinematic schemes and design solutions for turning the CPVT–module in the East–West and North–South directions are considered. The limits of change in these angles correlate well with the statistical indicators of the daily sunshine during the year for the region. Based on the measured characteristics of the developed and manufactured photovoltaic modules used in the developed CPVT system, and taking into account the above data, the minimum values of photovoltaic energy generation volumes are determined depending on the season. The average daily production of photovoltaic energy, for example, in June is up to 1.8 kW h. Based on the data obtained, the composition of the photovoltaic energy storage unit and the parameters of its components are determined.
