Standard examples are solar, wind, hydroelectric, and biomass products. Receiver - a device that receives solar energy and converts it to useful energy forms. The following figure from Shining On illustrates several types of receivers. Reflectance - the fraction or percent of a particular frequency or wavelength of electromagnetic radiation that is reflected from the surface of a substance without being absorbed or transmitted. Refraction - the bending of electromagnetic radiation by its passage through a medium of a high refractive index.
Light is refracted by passing through a lens, water, or the atmosphere.
Remote Sensing - the determination of a quantity by detecting it from a distance. A common application of remote sensing is the use of satellite-borne instruments to determine the location and amount of resources on the surface of the Earth. Rotating Shadow Band Radiometer - an instrument that determines total solar radiation and diffuse sky radiation by periodically shading the total sky sensor from the sun with a rotating shadow band . Below is a picture of a rotating shadow band radiometer at the Solar Radiation Research Laboratory . The following links allow you to move to the words beginning with that letter.
