I've heard that a lot of people are using a new type of solar panel. What is it and where can I get one?

A solar panel is a device that converts light energy from the sun into electricity. It consists of a photovoltaic (PV) cell, which is made up of a semiconductor material such as silicon, and an electrical circuit. The PV cell absorbs sunlight and converts it into direct current (DC). This DC current is then used to power electronic devices. Solar panels are typically installed on roofs or other areas with plenty of unobstructed sunlight. You can purchase solar panels online from many different retailers.
