What is the best material to reflect sunlight?

Many solar installations harvest energy by converting sunlight to heat; metal components efficiently absorb and transfer heat while withstanding high temperatures. For solar applications that use mirrors, thin coatings of silver, aluminum and other metals serve as good reflectors of light.

Can you use aluminum foil as a reflector?

We made our reflector by taping aluminum foil onto a large sheet of cardboard, for a powerful reflection with a silvery light, but an even simpler option is a piece of blank, white card. Hold it at the opposite side to the light source in relation to your subject, and the light will bounce back in to illuminate it.

Which side of aluminum foil reflects more heat?

The reflective surface will reflect heat and the matte side will absorb heat.
