Performance Analysis of Solar PV Panels Under Varying Partial Shading Conditions for Conventional and Hybrid Configurations
摘要
With the continuous increase in demand for electrical energy, the reliance on fossil-fuel-based sources not only hampers the environment but is also heavy on the pocket. The best option that can satisfy the world’s energy needs on its own is solar energy. For optimal energy output, solar panels can be interconnected using conventional techniques like Series (S), Parallel (P), Series-Parallel (SP), Honeycomb (HC), Bridge-Linked (BL), Total Cross-Tied (TCT), Double-Tied (DT), and Triple-Tied (TT); also hybrid connections, which are a mix of conventional techniques, can be used. The output of solar panels is significantly affected by the lack of proper incident solar insolation due to the shading phenomenon. This chapter evaluates the effectiveness of several solar panel interconnection methods for nine different types of shading patterns. The study’s main objective is to assess how well hybrid connections function to conventional ones, especially in partial shadowing/shading conditions (PSCs). It concludes that hybrid connections can produce comparable output with fewer interconnections (cross-ties) in many cases. The comparison charts indicate that the hybrid configurations considered can match the output of TCT connections, known for optimal output. This research aids in selecting connection techniques as alternatives to TCT connections based on specific shading patterns, determining which interconnections offer comparable output. As a result, solar arrays can operate with reduced complexity, lower cost, and fewer losses. The parameters under consideration are efficiency, mismatch loss, fill factor percentage power output, etc. The panel considered is SunPower SPR-220-WHT-U.
