Even in winter, solar panel technology is still effective; at one point in February 2022, solar was providing more than 20% of the UK’s electricity.1
Will a solar panel turn solar energy into direct current?
A solar panel will not turn solar energy into direct current until there is a circuit. If there is no circuit, the solar panel will just “sit there” as the photons will not be converted into electricity. The panels will get hotter true, but the modules are going to get hot anyway if you connect a load to it.
