Is photovoltaic passive or active?

Photovoltaic (PV) cells, or solar cells, are an active system in which small panels faced with semiconducting material turn sunlight into electricity. This material, usually made of silicon but potentially other polycrystalline thin films, generates a direct current when sunlight hits the panel.

What are the three forms of solar radiation?

Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.

How is solar radiation responsible for wind?

When the Earth's surface absorbs the sun's energy, it turns the light into heat. This heat on the Earth's surface warms the air above it. The air over the Equator gets warmer than the surface air near the poles.

What state has the least sunshine?

The absolute least sunny county in the lower U.S. is Island County, Wash. On an average day, it gets only about 60 percent of the solar radiation of a typical county in Southern California. The states bordering the Great Lakes — from Minnesota to New York — are all at the bottom of the sunlight distribution.
