Solar panels can seem like a mysterious or complex piece of technology, but the basic idea is surprisingly simple: they capture energy from daylight and convert it into electricity your home can use.

Professor Shanhui Fan and a team at Stanford University have built what they call “moonlight panels,” devices that generate electricity after the sun goes down by exploiting the temperature difference ...

In reality, many systems are set up so daytime production can help cover evening energy use as well.

Scientists at the University of New South Wales (UNSW) are developing a "reverse solar" panel, called a thermoradiative diode, which generates electricity by emitting infrared light (heat) into cold ...

Researchers at UNSW Sydney have developed a nanoscale device that converts low-energy infrared and red light into higher-energy visible light, a breakthrough that could eventually improve solar panels ...

If you stop to think about it, it’s a marvel that we can harness energy from the sun. But we do, thanks to solar panels equipped with photovoltaic cells that convert sunlight to electricity. That’s no ...

You need to maintain your solar panels if you want them to last. Here are my top care tips, plus how to test for faulty ones.
