A simple coating cools solar panels by reflecting the heat into outer space

No kidding, Stanford researchers actually showed it’s possible to cool solar panels by applying a special coating that reflects some of the heat back into space. The coating, called a photonic crystal cooling system, is transparent. This allows the light to reach the PV cells so these can generate energy, but – crucially – some of the heat is reflected back in space. It’s so good that the researchers showed their PV panels can even stay below ambient temperature, which is incredible by itself. If you know a thing or two about solar panels, then you’ll remember their efficiency is directly related to temperature. The cooler a panel is, the more of the sun’s energy it can convert into electricity. And we’re talking about a mere coating, which shouldn’t be too difficult to scale. Bit by bit, you if you multiply the extra efficiency by millions of panels you end up with a huge useful energy gain. This may be a game changer.

Tech improvements enable energy conservation in the home

In this energy conscious age it has become more important than ever to ensure that between our homes, place of work, and general everyday life, we do whatever we can to keep energy usage as well as subsequent energy bills at a minimum.
