This groundbreaking development solves a major problem with traditional solar panels, which only work when the sun is shining. But now, thanks to Professor Shanhui Fan and his team, that limitation may be a thing of the past.

The system uses a technique called Radiative Cooling, where heat escaping from the Earth’s surface at night is captured and turned into electricity. This is made possible by a special type of thermoelectric generator that converts thermal energy into electrical power.

When these generators are combined with regular solar panels, the setup can produce up to 50 milliwatts of electricity per square meter at night. While this output is much lower than the 200 watts per square meter that solar panels can generate during the day, it’s still enough to power small devices like LED lights, environmental sensors, mobile chargers, and other low-energy electronics.

Professor Fan says the technology is still in its early stages, but it holds huge promise — especially for remote areas, off-grid locations, and during emergencies where electricity isn’t available.

These new panels, being called “Moonlight Panels”, work best under clear night skies or bright moonlight, offering a whole new way to capture energy when the sun isn’t around.

Energy experts believe this could be a game-changer — not just for developing countries, but for the entire world in the quest for sustainable energy solutions.
