In solar power plants, the importance of temperature and its effect on panels is important. In photovoltaic systems, there is an inverse ratio between power output and panel temperature. As the temperature increase in the panels, the power received from panels will decrease. As the temperature in the cells inside the panel increases with the increase of the ambient temperature, the energy production will decrease.
an increase in temperature will occur in the panels. The current increase will occur due to the movement of the electrons released by the heating of the panels, but the voltage value will decrease.
Module temperature sensors are devices placed at the back of Module (BOM) to measure the temperature of the photovoltaic cells. These sensors generally use materials that are sensitive to temperature to accurately measure the temperature of the panel. The data collected by these sensors is then transmitted to the system’s monitoring unit for analysis.
Module temperature importance in PV modules:
* Performance Optimization
From a technical standpoint, the performance ratio (PR) of a photovoltaic installation is closely linked to the module temperature. In other words, for an accurate calculation of the PR, it is essential to obtain exact measurements of the module temperature.
* Preventing overheating
Module temperature sensors provide real-time data, enabling the system to implement cooling mechanisms or adjust the angle of the panels to prevent overheating.
* Durability of the system
High temperatures can lead to accelerated solar panel degradation over time. By constantly monitoring Module temperatures, system operators can implement actions to reduce thermal damage.
* Adjustments to weather conditions
Solar panels are exposed to changing weather conditions, including temperature fluctuations. The modules’ temperature sensors allow the solar system to adapt to these changes, making real-time adjustments to maximize energy capture over different seasons and weather patterns.
As the solar industry progresses, these sensors are becoming essential to the efficiency and operation of panels, making their implementation vital to unlocking the full potential of solar energy systems.
