Touted as a promising alternative energy source for decades, solar panels crown rooftops and roadside signs, and help keep spacecraft powered. But how do solar panels work?
Here, you'll find the latest news on solar power, including technologies like solar panels that collect the sun's rays and turn that light into energy.
Scientists have published a detailed road map to move 139 countries to 100 percent renewable energy by 2050, according to a recent study.
Solar power took a dip in the United States when the total eclipse swept across the country Monday (Aug. 21), as a new video shows.
From inefficient grids, shortfalls in policy, and even an eclipse, solar-energy collection faces no shortage of hurdles. Scientists have discovered another stumbling block: air pollution.
On the Tibetan Plateau in eastern China, 4 million solar panels silently soak up the sun as part of the Longyangxia Dam Solar Park.
Electronics such as solar panels and flexible gadgets may someday be able to heal their "wounds," thanks to tiny, self-propelled nanoparticles that detect and repair damage.
The lack of a carbon tax amounts to a hidden subsidy that incentivizes "bad behavior," Musk said Tuesday (Dec. 15) at the annual fall meeting of the American Geophysical Union, in San Francisco.
Japanese paper art has inspired scientists to design a new thin solar cell that tracks the sun using cuts and bending instead of large, clunky motors and gears.
Tesla has just unveiled a line of home batteries, but they aren't much different from the batteries that currently power their cars, experts say.
Researchers in Australia recently developed a solar energy system that can convert over 40 percent of the sunlight that hits it into electricity.
To capture more energy from the sun, one company is putting solar panels where they've never gone before: in the street.
A new kind of solar cell could store electrical energy without any help from traditional batteries, according to a new study.
