Determination of Electricity Produced using Different Types of Photovoltaic Tracking Modules

Abstract

The purpose of this study is to calculate the amount of electricity generated by various kinds of photovoltaic tracking modules. A solar module's mutual electric energy production is determined by its surface irradiance level, other photovoltaic modules, front surface reflectivity, and changes in the sunlight's spectrum mixing. The generation of electricity from a photovoltaic system can be obtained from climatic factors through numerical models that take into account specific mounting options such as sun tracking systems and fixed installation. Fixed-mount photovoltaic modules have a monthly average solar radiation output of 187–284 kWh/m²/month and a monthly electrical output of 150–200 MWh. A one-axis tracking system with an axis inclined at 35 degrees has an energy gain of approximately 183 to 292 kWh/m²/month on average monthly solar radiation and electrical energy between 137 and 220 MWh. In comparison, the gain of two-axis trackers is quite minor, about 3% in contrast to one-axis and stationary trackers. To limit the effects of self-shading and enhance the yield, tracker field design requires optimizing tracker location and moving behaviour.
