Such measurements are performed by a high quality solar radiation monitoring station that measures all three components of solar radiation: direct normal irradiance (DNI), di use horizontal irradiance (DHI) and global horizontal irradiance (GHI).
Local and remote photovoltaic monitoring systems are primarily used to collect data about solar panels for the purpose of maintenance and repair. Additionally, monitoring systems are used to measure and analyze energy production performance data. Another objective is to minimize hazards to personal safety associated with periodic manual controls.
In addition to output current and voltage data, measurements of solar radiation and panel temperature data were determined as the four main parameters in our research. Sensors and the data acquisition cards used to collect data and the data transmission methods are examined in detail.
To monitor the performance of the system the POA irradiance should be measured, along with the GHI, using high quality pyranometers (ISO 9060 Secondary Standard). The pyranometers can be mounted on the solar panel tracker or on a dedicated high precision sun tracker.
Using high-quality solar radiation monitoring at the plant, a dataset of performance can be built up, allowing more accurate forecasting of the future energy yield and financial returns [22, 23].
A mix of hardware and software makes up the smart photovoltaic (PV) monitoring system. It’s an internet platform that uses sensors, data loggers, and other components to conduct real-time monitoring of the solar system.
