Do Solar Panels Generate AC or DC Current?

Here''s why solar panels produce DC current: The Photovoltaic Effect. Solar panels generate DC electricity through a process called the photovoltaic effect. When sunlight hits the solar cells in a panel, it causes electrons to be knocked loose from their atoms. The solar panels capture these free electrons and direct them into an electric current.
