The solar array of such off-grid PV system charges a rechargeable battery, which powers a fluorescent or LED lamp during the night. Solar street lights are stand-alone power systems , and have the advantage of savings on trenching, landscaping, and maintenance costs, as well as on the electric bills, despite their higher initial cost compared to conventional street lighting.

Anti-reflective coating

Reflectance is also decreased for wavelengths in a broad band around the center. A layer of thickness equal to a quarter of some design wavelength is called a 'quarter-wave layer'. The most common type of optical glass is crown glass, which has an index of refraction of about 1.52. An optimal single-layer coating would have to be made of a .

Solar energy can be captured from periods of relative abundance day time/summer , and released to boost the temperature during cooler periods night time/winter . Waste heat from livestock can also be used to heat greenhouses, e.g., placing a chicken coop inside a greenhouse recovers the heat generated by the chickens, which would otherwise be wasted.

Reflective surfaces climate engineering

Solar reflectance, also known as albedo, is the ability to reflect sunlight. It is expressed either as a decimal fraction or a percentage. A value of 0 indicates that the surface absorbs all solar radiation, and a value of 1 or 100% represents total reflectivity. Thermal emittance is the ability to emit absorbed heat.

Specular reflection

Specular reflection, or regular reflection, is the mirror-like reflection of waves, such as light, from a surface.. The law of reflection states that a reflected ray of light emerges from the reflecting surface at the same angle to the surface normal as the incident ray, but on the opposing side of the surface normal in the plane formed by the incident and reflected rays.


Reflectivity is the limit value of reflectance as the sample becomes thick; it is the intrinsic reflectance of the surface, hence irrespective of other parameters such as the reflectance of the rear surface. Another way to interpret this is that the reflectance is the fraction of electromagnetic power reflected from a specific sample, while reflectivity is a property of the material itself .

Solar Reflectivity R and Solar Reflectance Index SRI by Color

Solar reflectivity or reflectance is the ability of a material to reflect solar energy from its surface back into the atmosphere. The SR value is a number from 0 to .0. A


In radiometry, radiance is the radiant flux emitted, reflected, transmitted or received by a given surface, per unit solid angle per unit projected area. Spectral radiance is the radiance of a surface per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength.

Stele of Ankh-ef-en-Khonsu

Origins. The stele is a fairly typical example of a late Third Intermediate Period Theban offering stele dating to the late Dynasty 25/early Dynasty 26. It was discovered in 1854 as part of a large burial of priests of Montu at Dayr al-Bahri, and included the coffin of the dedicant, Ankh-ef-en-Khonsu.


Albedo / æ l ˈ b iː d oʊ / Latin: albedo, meaning & 39;whiteness& 39; is the measure of the diffuse reflection of solar radiation out of the total solar radiation and measured on a scale from 0, corresponding to a black body that absorbs all incident radiation, to 1, corresponding to a body that reflects all incident radiation.

Reflection coefficient

In telecommunications and transmission line theory, the reflection coefficient is the ratio of the complex amplitude of the reflected wave to that of the incident wave. The voltage and current at any point along a transmission line can always be resolved into forward and reflected traveling waves given a specified reference impedance Z 0.


Silversun is a science fiction children& 39;s television series made in Australia by the Australian Broadcasting Corporation ABC . The show features the adventures of the adolescent members of the crew of the Star Runner, an interstellar spaceship carrying a cargo of 550 cryonically suspended colonists 'cryons' to their new home, the Silver Sun.

Solar gain

Solar gain also known as solar heat gain or passive solar gain is the increase in thermal energy of a space, object or structure as it absorbs incident solar radiation. The amount of solar gain a space experiences is a function of the total incident solar irradiance and of the ability of any intervening material to transmit or resist the radiation.
