Temperature coefficients differ slightly between monocrystalline and polycrystalline solar panels, although the differences are generally minimal. Both types typically have negative temperature coefficients, indicating that their efficiency decreases as temperature increases.
Monocrystalline Solar Panels
- Temperature Coefficient: Monocrystalline panels usually have temperature coefficients within the range of -0.38% to -0.44% per °C. For example, Maxeon monocrystalline panels have a coefficient of -0.38%.
- Performance: Monocrystalline panels are generally more efficient than polycrystalline ones, but their temperature coefficients are not significantly better.
Polycrystalline Solar Panels
- Temperature Coefficient: Polycrystalline panels typically have a temperature coefficient in the range of -0.41% to -0.50% per °C.
- Performance: Polycrystalline panels are less efficient overall but can be more cost-effective.
Key Differences
- Efficiency and Cost: Monocrystalline panels tend to be more efficient but also more expensive. Polycrystalline panels are often more cost-effective with slightly lower efficiency.
- Production Process: The production process for monocrystalline involves creating a single crystal structure, which generally offers better performance. Polycrystalline panels are made from multiple crystals, resulting in a slightly lower efficiency but at a lower cost.
In summary, while monocrystalline solar panels may have a slightly better temperature coefficient than polycrystalline ones, the difference is not dramatic. The choice between the two often depends on budget and energy requirements rather than temperature performance alone.
