6 FAQs about [Materials that absorb solar energy]

Which materials are good absorbers of solar energy?

Non-metallic materials such as brick stone and brick are good absorbers of solar energy, especially if they have dark coloring. Plastics and wood may make good energy absorbers, but many types are not suitable for solar applications because most plastics have relatively low melting points and wood may catch fire.

Is a metal a 'ideal' material for solar absorption?

Now researchers at MIT say they have accomplished the development of a material that comes very close to the “ideal” for solar absorption. The material is a two-dimensional metallic dielectric photonic crystal, and has the additional benefits of absorbing sunlight from a wide range of angles and withstanding extremely high temperatures.

Which materials are suitable for solar energy equipment?

With reflective coatings, however, plastic materials may be suitable for solar energy equipment, as long as temperature demands are modest. Clear glass and plastic absorb very little solar energy, so they make good lenses, windows and transparent enclosures (See Reference 3, "Absorption").

Which color absorbs the most solar energy?

A material's color and shade affect the amount of light it absorbs or reflects; dark colors reflect less light to your eye, so they absorb more light. A "flat black" material having no glossy reflections absorbs the most solar energy. Conversely, light colors reflect more light than dark ones, and white reflects the most.

Is plastic a good solar energy absorber?

Plastics and wood may make good energy absorbers, but many types are not suitable for solar applications because most plastics have relatively low melting points and wood may catch fire. With reflective coatings, however, plastic materials may be suitable for solar energy equipment, as long as temperature demands are modest.

Which surface absorbs the most solar radiation?

Earth’s surfaces are better at absorbing solar radiation than air, especially surfaces that are dark in color. You can feel this on a cold winter day when the sunshine warms your face and the air around you remains cold. Your skin and your clothes also absorb solar radiation and convert it to heat.
