A lot of people do not understand the difference of solar heating panels and solar energy panels. Well I will tell you right now. Solar energy panels are used for generating electricity to power all your lights and stuff like that in your house. Solar heating panels, aka solar thermal panels, are used when you want to heat your home or whatever you connect them to. The nice thing about these panels is that they are more efficient because they do not have to transform the sunlight energy to electrical energy.
How does this process work?? Well it is pretty simple when you look at it. First, active solar heating is captured by these panels and then used to heat a fluid either liquid or air. This medium is then used to transfer the heat directly to an interior space or a storage system for later use.
