Do Solar Panels Need Direct Sunlight. A ring solar panel uses photovoltaic cells to generate electricity through the photoelectric effect. It is available only when there is direct sunlight.
Solar panels do not need direct sunlight to work even though maximum efficiency is reached when the sun is shining, electricity is still produced on cloudy days and during winter. Even though solar panels need direct sunlight for maximum electrical output, installing solar panels in shady weather is still feasible. Both forms of sunlight carry photons, which is what the solar panels convert into electric current.
