Performance Evaluation of Solar PV Array Under Various Partial Shading Conditions

Abstract

The total installed capacity (TIC) of power generation in India is approx. 370 GW out of which the contribution of non-fossil fuel-based generation is nearly 22% (77.5 GW) and solar radiation-based generation accounts for TIC 8% (29.7GW). The United Nations Framework Convention on Climate Change (UNFCCC) dealing with greenhouse mitigations sets a standard to contain an increase in global temperature to 2 °C in this century. The participant member nations of Paris agreement 2015 agreed on “intended nationally determined contribution” (INDC) to reduce carbon emission. India’s INDC in the power sector is to achieve 175 GW through renewable energy by the year 2022. Considering these targets, India has put special focus on solar power generation with a target of 100 GW. In this analysis, a very important issue of partial shading and consequent non-uniformity of solar irradiance under various types of PSC is investigated. The series–parallel (SP) PV array topology is implemented on hardware platform. And results are being computed respectively.
