Monocrystalline vs. Polycrystalline: Which One Is the Best ...
2021-4-10 · Polycrystalline solar panels have a higher temperature coefficient compared to monocrystalline ones. Generally, solar panels based on polycrystalline solar cells have a temperature coefficient in the -0.3% to -1% range. Accordingly, these solar panels tend to lose more of their efficiency temporarily should the temperature rise. This means that polycrystalline solar panels may not deliver optimal performance in high-temperature areas.
