Shading Effect on Output Power of Gried-Tied PV Systems: A Case Study

In this case study, the shading effect of 480 kW Solar power plant in ilkadım-Samsun was investigated. It is well known that the power generation of photovoltaic systems is significantly influenced by the partial or complete shading of the cells. The substation of the solar power plant caused the falling energy on a directory panel to be adversely affected by the generated energy. The performance of the panels effected by the shadow on the total power generation has been monitored and analyzed. Despite of the dual MPPT tracking inverters, it was observed that the loss was up to 4.80%. The results show that the generated PV voltage has fallen due to the shade.
