The overall reliability of the system can be increased by lowering the failure probability of these cut sets. In a solar PV system’s FT, basic events are connected in sequence via an OR gate. From the basic theory of probability, the reliability of the system will be determined by Equations (2) and (3).
Conclusion: Solar energy is the next option to compete with the shortage of electricity through large-scale solar power plants. This paper presents the industrial technique to estimate the excess energy of large-scale solar power plants based on the results of performance analysis of energy production data.
Solar PV plant performance measured on the basis of PR or CUF of the plant for particular time of span of energy generation through solar PV at any location.
As a consequence of the fog on the modules, the irradiance was low, and the panel became dusty. Based on this reason, plant injected very small amount of energy and PR value also dropped. Sometimes PV modules also receive dirt damage due to birds flying over the panels. In this situation, soiling loss is increased to let down the power generation.
It is observed that the occurrence of different faults in the PV system may reduce the power output by up to 19% of its capacity. Hence the overall effect of the presence of fault would be lowered power generation, reduced reliability and lifetime, and increased operation and maintenance cost of the PV system.
Results showed that solder bond failure, broken cell, broken interconnect (finger interruption), rack structure, grounding/lightning protection system, delamination, discoloration, and partial shading are the most critical faults which severely degrade the performance of the PV systems.
