Looking for a budget friendly solar panel for your home? Polycrystalline panels, often known as “multi crystalline panels,” are a popular option among homeowners. These solar panels are made up of silicon solar cells that come from multiple silicon crystals. Their rectangular shape, which is generated when silicon is heated and poured into a mould, can be identified within a solar panel. However, since their silicon purity and structure are lower than monocrystalline panels, they are less efficient in terms of energy conversion and space. They also have lower heat tolerance, making them less efficient in high temperature environments.
