Blue Solar Panels (Polycrystalline)
- Made from multiple silicon fragments, giving them a blue hue.
- Efficiency: Typically have lower efficiency (around 13-16%) due to:
- More impurities: The multiple crystals create more boundaries that can hinder electron flow.
- Less efficient light absorption: The blue color reflects some light.
Black Solar Panels (Monocrystalline)
- Made from a single crystal of silicon, resulting in a uniform black color.
- Efficiency: Generally have higher efficiency (typically 18-23%) due to:
- Fewer impurities: The single-crystal structure has fewer defects, allowing electrons to flow more freely.
- Better light absorption: Black surfaces naturally absorb more light.
- Performance in low light: Often perform better in low-light conditions (cloudy days, mornings, evenings).
