  • Climate conditions affect solar cell performance more than expected
    on December 13, 2017 at 7:37 pm

    Researchers can now predict how much energy solar cells will produce at any location worldwide. Surprisingly, they identified that two types of solar cells can vary in energy output by 5 percent or more in tropical regions. This gap occurs because solar energy can shift depending on local temperature and water in the atmosphere. Their work emphasizes that solar products may behave differently depending on their environment. […]
