The paper presents an experimental energy and safety assessments of a 2.5 MWp capacity grid-tied solar photovoltaic power plant having installed at Pune, India.. The comprehensive step-by-step assessments of visual inspection, field testing, and evaluation of reasons contributing to different energy losses, precisely the effect of soiling has been made. The field testing include in detail the testing of solar photovoltaic strings and String Combiner Box (SCB), which encompasses tests of open circuit voltage, short circuit current, earth continuity, insulation resistance, and pull-out and contact resistance test for PV plug connectors to check the efficacy of plant components and the faults in the system. The string, SCB, and inverter operational voltage, current, and power are measured and analyzed. Thermal imaging of solar photovoltaic modules and sub-components based on temperature variance gauges the faults and losses in the plant are carried out. It is found that the effect of soiling on the system's overall health and energy perspective using term Soiling Ratio approach for cleaning plants rather than a fixed cleaning cycle on power plant plant performance and efficiency. It is concluded that the research findings helpful for further research on effect of soiling ratio of existing plant.
