Abstract

Partial shading restrains the output of photovoltaic (PV) system, as mismatch losses are prominent when shade dispersion is uneven in an array. Partial shading (PS) is unavoidable in residential installations and it is therefore essential to improve the output under such conditions. Strategies that reconfigure the shaded panels or alter the interconnections are generally adopted to improve the yield under PS conditions. The static reconfiguration technique that is based on puzzle pattern has an edge over the dynamic technique as it voids the usage of sensors, switches and complicated computations and hence offers an efficient and economically viable solution in addressing the partial shading issues in small scale installations. This paper proposes three new shade resilient structures (SR1, SR2 and SR3) and analyses the performance under six different shading cases that mimic the real world shading scenarios.
