The RICH SOLAR 80W 12V Flexible Monocrystalline Solar Panel is unique because it is monocrystalline, meaning that it is made of a single crystal. This makes it more efficient than other types of solar panels. It also has a flexible design so that it can be mounted in a variety of ways. Additionally, it has a durable ETFE coating that protects it from the elements. Finally, it comes with four pre-drilled mounting holes, and two 24-inch panel leads for easy installation.
