While the output is reduced compared to bright, sunny days, most panels can still produce between 10–25% of their usual capacity in overcast conditions.

Flat solar panels work by using the photovoltaic effect, which is the process that converts sunlight into electricity. When sunlight hits the solar cells in the panel, it excites electrons, creating an electric current. This is how energy is captured and transformed for use.
