Can a solar cooker work in cloudy weather?

Yes, a solar cooker can work in cloudy weather, but its efficiency drops. It needs sunlight, even diffused light, to generate heat. On partly cloudy days it may cook slowly, while on heavily overcast days it may not reach safe cooking temperatures. Insulated box-type solar cookers perform better than panel cookers in such conditions.
