ABSTRACT 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.
