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.
This is why PV systems are typically designed to operate within an optimal temperature range, and cooling techniques may be employed to maintain optimal performance. Photovoltaic cells exhibit optimal efficiency within a specific temperature range, typically between 15°C (59°F) and 35°C (95°F).
Temperature coefficients are used to quantify the temperature dependence of various performance parameters of a photovoltaic (PV) cell, such as open-circuit voltage (Voc), short-circuit current (Isc), maximum power (Pmax), and efficiency. These coefficients represent the rate of change of a particular parameter with respect to temperature.
Temperature plays a crucial role in determining the efficiency and performance of photovoltaic (PV) cells. The efficiency of a PV cell refers to its ability to convert sunlight into electrical energy, and this efficiency is directly influenced by the operating temperature of the cell.
The voltage output is greater at the colder temperature. The effect of temperature can be clearly displayed by a PV panel I-V (current vs. voltage) curve. I-V curves show the different combinations of voltage and current that can be produced by a given PV panel under the existing conditions.
When considering solar panels for hot climates, pay attention to the temperature coefficient. This tells you how much efficiency the panel loses for every degree above the standard test temperature of 25°C (77°F). Panels with a lower temperature coefficient, closer to zero, perform better in high temperatures.
