Phase Changing Materials for Solar Panels
“How can we use phase-changing materials to cool down solar panels?”
Solar PV is the fastest growing energy system in the world. But that doesn’t mean that it’s without its problems. When they become too hot, they become very inefficient and reject a lot of heat into nearby structures. One way to counter this is to attach a layer of Phase Changing Materials at the back of the panel. The phase-changing material is a material at its critical value so it can absorb a voluminous amount of latent heat without changing its temperature. Not only does it act as a passive heatsink but it can store this thermal energy to be used in other applications such as heating water. Phase changing materials are usually attached in a capsule behind the PV panel and have an air gap behind them to ensure cooling. This is a great example of Phase Changing Materials for Solar Panels.
