Performance evaluation of monocrystalline and polycrystalline-based solar cell

This paper exhibits the performance of crystalline-based solar cells (polycrystalline and monocrystalline) as well as the comparative analysis of these solar cells following various types of orientation in the solar plant. Since the global energy demand is increasing rapidly, different sorts of renewable energy have been used in the last decades to meet this massive demand all over the world. From recent studies, solar has been considered the most promising among these renewable sources. To analyze the performance, the geographical site (Savar, Dhaka) was selected which has a latitude of 23.8538 degrees and a longitude of 90.2534 degrees. In this study, the most effective polycrystalline and monocrystalline solar cell has been founded which is 440 and 370 wp, respectively. Regarding this, a grid-connected PV system (12.3 Kwp) has been simulated which showed the performance ratio of the monocrystalline cell was 83.55%, which was better than the polycrystalline-based solar cell which was 79.6%. In terms of different kinds of orientations, monocrystalline at dual-axis tracking planes showed the highest value of energy injection to the grid was 25.8 MWh/year, while the least value has been founded in the fixed orientation plane which was 20.6 MWh/year. In this perspective, polycrystalline showed 23.9 and 19.5 MWh/year for dual-axis tracking and fixed orientation planes, respectively. Monocrystalline showed more energy injected into the grid compared to polycrystalline technologies for every orientation in the plant as well as the highest value of performance ratio.
