Photovoltaic and solar hot water systems can make use of both direct radiation and diffuse radiation. Concentrated solar power, on the other hand, requires a lot of direct radiation to do much of anything at all. Reflected radiation describes …
Diffuse solar energy is the result of the atmosphere attenuating, or reducing the magnitude of the Sun's beam. Some of the energy removed from the beam is redirected or scattered towards the ground - the rate at which this energy falls on a unit horizontal surface per second is called the diffuse solar irradiance.
The values are usually highest in clear sun conditions during the summer, and lowest during winter or very cloudy days. Diffuse solar exposure is the total amount of solar energy falling on a horizontal surface from all parts of the sky apart from the direct sun. The daily diffuse solar exposure is the total diffuse solar energy for a day.
On an extremely overcast day, pretty much 100% of the solar radiation is diffuse radiation. Generally speaking, the larger the percentage of diffuse radiation, the less the total insolation. The percentage of the sky's radiation that is diffuse is much greater in higher latitude, cloudier places than in lower latitude, sunnier places.
Photovoltaic and solar hot water systems can make use of both direct radiation and diffuse radiation. Concentrated solar power, on the other hand, requires a lot of direct radiation to do much of anything at all. Reflected radiation describes sunlight that has been reflected off of non-atmospheric things such as the ground.
The origin of the diffuse light that is reaching the solar cells is either (a) scattering structures in the module top sheet or (b) diffuse irradiance incident on the modules. Diffuse irradiance is defined as the portion of the sunlight that does not arrive at the surface of interest in a straight line from the sun .
Asphalt reflects about 4% of the light that strikes it and a lawn about 25%. However, solar panels tend to be tilted away from where the reflected light is going and reflected radiation rarely accounts for a significant part of the sunlight striking their surface.
