But in the solar cell power supply system, the internal resistance of solar cell is affected not only by the intensity of sunlight but also by the ambient temperature. To aim at
Rooftop Schemes in Sri Lanka Net Metering Net metering is a billing mechanism that credits solar energy producer (Prosumer) for the electricity they add to the grid, but no payment will be made for the excess electricity
The depletion of fossil fuels and carbon emission issues have transformed power systems from conventional systems to renewable systems [1,2,3].Moreover, the need for energy security and economic stability has
PV faults in solar PV array results significant power loss, lower reliability, very fast panel degradation, and further risk of fire (Gokmen et al. 2013 ). This chapter presents a comprehensive literature review along with a critical analysis of fault diagnosis and condition monitoring for solar PV systems. Major contributions are:
Reliability, efficiency and safety of solar PV systems can be enhanced by continuous monitoring of the system and detecting the faults if any as early as possible. Reduced real time power generation and reduced life span of the solar PV system are the results if the fault in solar PV system is found undetected.
Firstly, the review of solar PV monitoring systems based on data processing modules with its design features, implementation, comments or suggestions, and limitations is presented. Secondly, various data transmission protocols are studied for solar PV monitoring systems.
Additionally, the review emphasizes the significance of data acquisition and monitoring in PV systems for successful fault detection. The application of model-based fault detection methods in PV systems, while demonstrating efficacy, is not without its limitations.
Thus, the accuracy and performance of the solar PV system can be improved by employing an efficient solar PV monitoring system . Monitoring is the process of observing and recording the parameters from the solar PV power plant in real-time.
Authors in have reported that the solar PV system suffers an annual degradation rate of 0.923% when it is operated at harsh environmental conditions. In addition, the efficiency drop in a solar PV system is because of the effect of various kinds of faults and failures, which the system suffers.
