Monocrystalline panels are made from a single cylindrical silicon crystal that is sliced into silicon wafers spread across the panel. On the other hand, polycrystalline panels are made from multiple silicon crystals that are melted together and laced throughout the panel. Between the two types, monocrystalline panels have the highest efficiencies, so they capture solar rays and convert them into electricity more effectively. However, they are also more expensive than their polycrystalline counterparts. On the other hand, polycrystalline panels are rather sensitive to high temperatures. However, despite those differences, both panel types put out essentially the same amount of power.
Additionally, both monocrystalline and polycrystalline panels are first-generation solar panels, which means their technology has been around for a while and it’s had time to mature. More mature solar technology is often more reliable than newer counterparts because solar experts have had time to improve the technology and make it more effective and efficient.
