Before diving into the specs, it's essential to understand the different types of solar panels. The three main types are monocrystalline, polycrystalline, and thin-film panels. Monocrystalline panels are made from a single crystal structure and are known for their high efficiency and space-saving design, making them ideal for residential installations. Polycrystalline panels, composed of multiple crystal structures, are generally less efficient but are often more affordable. Thin-film panels, while lightweight and flexible, typically have lower efficiency rates and are more suitable for specific applications.
