On-grid and off-grid building integrated photovoltaic (BIPV) systems require a large size BIPV array (LSBA) as their major renewable energy generator. Partial Shading (PS) significantly contributes to power loss in LSBA. One effective solution to mitigate the adverse effect of PS in LSBA is the application of fixed or static BIPV array configurations (BIPV-ACs). This research article critically compares the different fixed BIPV-ACs for modelling, designing and critical analysis of LSBA. Different existing and proposed fixed BIPV-ACs are modelled and simulated in MATLAB/Simulink under six dissimilar cases of PS patterns. Further, the performance is investigated in terms of global maximum power point (G-M-PP), mismatch loss (ML), fill factor (FF), efficiency (η), relative power loss (RPL) and relative power gained (RPG) to identify the best BIPV-AC. Experimental justification of simulation results under two PS pattern cases is reported. The best BIPV-ACs with high G-M-PP and low ML are Total-Cross-Tied (TCT), Triple-Tied (TT), Modified Triple-Tied (M-TT) and Hybrid Bridge-Linked Total-Cross-Tied (H-BL-TCT). Finally, the comprehensive critical analysis reveals that the H-BL-TCT array is the best performing array with low ML, high FF and η, and high G-M-PP with low wiring requirements than the TCT array. The simulation results conclude that the H-BL-TCT array improves G-M-PP by 6.40 %, reduces ML by 4.23 %, and improves FF & η by 4.58 % and 0.54 %. The experimental results infer that the H-BL-TCT array improves G-M-PP by 0.83 %, reduces ML by 0.75 %, and improves FF & η by 0.88 % and 0.09 %. [ABSTRACT FROM AUTHOR]

The electricity demand of the world is growing at a rapid pace. On the other hand, pollution levels due to conventional power generating techniques are drastically increasing and resulting in harmful environmental issues and impacts. As an alternative to this, renewable or clean energy generation from solar photovoltaic's (PV) in large scale grid connected systems is being increasingly encouraged at the present time. One of the emerging trends in solar PV module power generation is building integrated photovoltaic (BIPV) systems. It meets the local load demands of the building or residential systems and can be used as a stand-alone or on-grid connected system. This paper briefs about the development and recent trends related to renewable energy generation from BIPV systems and its maximum power generation techniques. It also describes both the current-voltage (I-V) and power-voltage (P-V) characteristics of various BIPV products at dissimilar values of solar irradiation. With BIPV, the building or residential components like the roof, an outer wall, window glass, etc., are replaced by PV array module and hence a dual purpose is served with a reduction in the overall cost.
