Polycrystalline Solar Panels

Polycrystalline (multicrystalline) solar panels are the most common, because they are cheaper than monocrystalline solar panels. The reason is in the way of silicon producing. Polycrystalline solar panels are made from the same material – silicon, but instead if growing silicon in monocrystal it is fused and crystallized. As polycrystalline cells contain many crystals, they have less perfect surface than monocrystalline cells. They absorb less solar energy and produce a little less electrical power per square meter. They have higher efficiency than thin-film solar panels.
