The primary difference in temperature coefficients between monocrystalline and polycrystalline solar panels lies in how their efficiency declines with increasing temperatures.
- Monocrystalline Solar Panels: These panels typically have a temperature coefficient ranging from -0.3% to -0.5% per degree Celsius. This means that for every degree Celsius increase in temperature, their efficiency decreases by 0.3% to 0.5%. This lower temperature coefficient makes them more efficient in warmer climates because they lose less power as temperatures rise.
- Polycrystalline Solar Panels: Polycrystalline panels usually have a slightly higher temperature coefficient, often between -0.3% and -1% per degree Celsius. This higher coefficient indicates that polycrystalline panels experience a more significant efficiency loss with rising temperatures, making them less optimal for extremely hot climates compared to monocrystalline panels.
In summary, monocrystalline solar panels are better suited for hot environments due to their lower temperature coefficient and higher efficiency, while polycrystalline panels, though less expensive, may lose more efficiency in high temperatures.
