- Company Profile:
The average amount of solar radiation that reaches the earth's upper atmosphere on a surface perpendicular to the sun's rays; equal to 1353 Watts per square meter or 492 Btu per square foot.
Industry:Energy
A method of growing large size, high quality semiconductor crystal by slowly lifting a seed crystal from a molten bath of the material under careful cooling conditions.
Industry:Energy
The use of solar thermal energy or solar electricity to power a cooling appliance. Photovoltaic systems can power evaporative coolers ("swamp" coolers), heat-pumps, and air conditioners.
Industry:Energy
A chemical bond associated with an atom on the surface layer of a crystal. The bond does not join with another atom of the crystal, but extends in the direction of exterior of the surface.
Industry:Energy
Electromagnetic energy transmitted from the sun (solar radiation). The amount that reaches the earth is equal to one billionth of total solar energy generated, or the equivalent of about 420 trillion kilowatt-hours.
Industry:Energy
The number of consecutive days the stand-alone system will meet a defined load without solar energy input. This term is related to system availability.
Industry:Energy
Intermediate-grade silicon used in the manufacture of solar cells. Less expensive than electronic-grade silicon.
Industry:Energy
Electronic circuit to convert direct current voltages (e.g., photovoltaic module voltage) into other levels (e.g., load voltage). Can be part of a maximum power point tracker.
Industry:Energy
A battery with large plates that can withstand many discharges to a low state-of-charge.
