- Monocrystalline Silicon (Mono-Si): Made from a single continuous crystal structure, which gives them a uniform appearance and higher efficiency compared to other types. They are relatively expensive to produce.
- Polycrystalline Silicon (Poly-Si or mc-Si): Produced by melting multiple silicon crystals together. They have a speckled appearance and are typically less efficient than monocrystalline panels but are more cost-effective.
