A Solar Lease is a legal document outlining the terms under which one party agrees to rent Solar property from another party. A Solar Lease can be a better and more affordable investment than purchasing a solar PV system with…

Solar Spectrum comprises of the entire range of wavelengths of solar radiation.The energy in solar irradiation comes in the form of electromagnetic waves of a wide spectrum. It includes ultraviolet (UV), infrared(IR) and visible spectrum.

Sputtering implies the deposition of a metal on a surface by using fast ions to eject particles of it from a target. Sputter deposition is a physical vapor deposition (PVD) method of thin film deposition by sputtering. This involves ejecting…

Staebler-Wronski Effect is the degradation of electrical output of hydrogenated amorphous silicon solar cells as a result of prolonged illumination.The defect density of hydrogenated amorphous silicon (a-Si:H) increases with light exposure, causing an increase in the recombination current and reducing…

A coefficient expressing the relation between a change in a physical property and the change in temperature that causes it. Solar Panels have negative temperature coefficients which means that when the temperature rises and solar panels heat up, the power…

Solar Battery charging voltages should be corrected based on battery temperature. This adjustment is referred to as temperature compensation, a charging feature that helps ensure that a battery is neither undercharged nor overcharged regardless of battery temperature. Battery charging being…

In order to minimize surface reflection losses, surface texturing is used and such a cell is called Textured Solar Cell. Any “roughening” of the surface reduces reflection by increasing the chances of reflected light bouncing back onto the surface, rather…

The angle between the horizontal plane and the solar panel is called the tilt angle.

The trapping of light by refraction and reflection at critical angles inside a semiconductor device so that it cannot escape the device and must be eventually absorbed by the semiconductor. Photovoltaic efficiency can be increased by the total internal reflection…

A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction.Transformers are used in power systems to step up or step down voltage. The converted solar DC voltage to AC voltage is fed into…
