Temperature regulation is key to maximizing the potential of solar panels and extending their lifespan. This article examines the innovative use of proportional-integral-derivative (PID) controllers for this purpose.
According to the manufacturing standards, 25 °C or 77 °F temperature indicates the peak of the optimum temperature range of photovoltaic solar panels. It is when solar photovoltaic cells are able to absorb sunlight with maximum efficiency and when we can expect them to perform the best.
Understanding these effects is crucial for optimizing the efficiency and longevity of photovoltaic systems. Temperature exerts a noteworthy influence on solar cell efficiency, generally causing a decline as temperatures rise. This decline is chiefly attributed to two primary factors.
The conversion efficiency of a solar panel decreases by around 0.4 to 0.5% for every degree Celsius increase in temperature. This means that if a solar panel's temperature increases by 10 degrees Celsius, its conversion efficiency could decrease by 4 to 5%, leading to a significant reduction in its overall performance.
Other than decreased efficiency, higher operating temperatures also lead to the degradation of PV cells and, thereby, affecting their effective lifespan. The accumulation of thermal energy within the PV panels as a consequence of continuous exposure to sunlight is detrimental as it results in a deterioration in electrical performance.
A thermoelectric cooling system can be used for solar photovoltaic system by integrating the thermoelectric materials with the heat sink that is in contact with the solar panels. The hot portion of thermoelectric materials would be connected to the solar panels, while the cold side is exposed to the external environment.
When the temperature of a solar panel rises, its efficiency decreases, and its output power reduces. This is because solar panels generate electricity by converting sunlight into direct current (DC) electricity, and as the temperature of the panel rises, the efficiency of this conversion decreases.
