Fossil fuels are the only measure to encounter the day today life activities. Slowly the depended resources are getting depleted and continuous exposure towards it is resulting in the negative eﬀect on the environment. More to the point, energy demand of the world has increased in past few decades and therefore the society is searching for an alternate viable solution. Solar photovoltaic (SPV) energy is widely used among the renewable energy sources and the photovoltaic cell can directly convert solar energy into electricity. On the other hand, eﬃciency of SPV cell is negatively aﬀected during the fractional shading state. Fractional shading conditions occur on the photovoltaic systems due to the passing clouds in the sky, nearby building shadow, moving objects, tree etc. As a result, power generated from the photovoltaic system is less than the expected value. One of the best solutions for this issue will be the multiple array conﬁgurations scheme. In this proposed article, conventional SPV array conﬁguration such as series parallel (SP), bridged linked (BL) and honeycomb (HC) are compared under different cases with the newly proposed complete cross tied configuration to yield the possible peak power for different fractional shading states. This approach can be done with 4×4 SPV array under six diﬀerent shading cases and the simulations of all shading cases are implemented using MATLAB/Simulink respectively.
