For a solar cell with an absorption rate of 70%, the predicted panel temperature is as high as 60 °C under a solar irradiance of 1000 W/m 2 in no-wind weather. In days with a wind speed of more than 4 m/s, the panel temperature can be reduced below 40 °C, leading to a less significant heating effect on the photoelectric efficiency of solar cells.
Thin film solar panels are less affected by a temperature rise compared to silicon-based panels. Their temperature coefficient, which is the percentage reduction in efficiency for a unit °C increase in temperature, is −0.0984% compared to −0.109% for mono-crystalline panels and −0.124% for polycrystalline panels .
A solar panel temperature coefficient is a metric representing the rate at which a solar panel’s efficiency decreases as its temperature rises. With record-high temperatures these days, it’s a metric you need to know about. It’s an essential efficiency factor because solar panels operate most effectively when they’re under direct sunlight.
The key factor here is the solar panel temperature coefficient. In simple terms, the temperature coefficient tells you how much power output drops as the temperature goes up. Most solar panels have a coefficient between -0.3% to -0.5% per °C. So, for every degree above 25°C, the efficiency decreases by that percentage.
The actual heating effect may cause a photoelectric efficiency drop of 2.9–9.0%. Photovoltaic (PV) panel temperature was evaluated by developing theoretical models that are feasible to be used in realistic scenarios. Effects of solar irradiance, wind speed and ambient temperature on the PV panel temperature were studied.
There are many differences regarding crystalline silicon and thin-film solar panel technology. One important difference is how the temperature affects the efficiency of each technology, c-Si solar cells are more affected by temperature than thin-film technologies.
Mono and poly panels typically have a temperature coefficient between -0.3% and -0.5% per °C, while thin-film panels are around -0.2% per °C. This makes them better at handling the heat and losing less efficiency in high temperatures.
