Researchers in Spain are working on the nano scale to identify better heat-catching surfaces for concentrated solar power stations — and nanoneedles are proving more efficient for the task than ...

Installing solar panels is a smart step for many homes, but understanding how tariffs, shading and energy use affect performance can help you get even more from your system ...

Monocrystalline, polycrystalline or thin-film? Here’s how the main types of solar panel compare on efficiency, lifespan, and the roof space you’ll need.

Researchers have developed a new type of solar power system that can produce both electricity and heat at the same time—an innovation that could help industries capture carbon dioxide (CO₂) from their ...

Heatwaves can slightly reduce the efficiency of solar panels, mainly because higher temperatures lower panel voltage. But in the UK, the penalty is usually modest, and Britain’s record hot day in July ...

Solar power is already one of the fastest growing sources of electricity on the planet, yet scientists say it is still only scratching the surface of what is physically possible. A wave of ...
