The sputtering of the lunar surface by the solar wind is examined as a possible mechanism of mass fractionation. Two distinct contributions to this mechanism are considered: (1) the tendency for a greater fraction of the heavier sputtered atoms to fall back to the surface under lunar gravity; and (2) mass-dependent kinetic effects that arise in the sputtering process itself. Calculations ...

That is why all solar panel manufacturers provide a temperature coefficient value (Pmax) along with their product information. In general, most solar panel coefficients range between minus 0.20 to minus 0.50 percent per degree Celsius. The closer this number is to zero, the less affected the solar panel is by the temperature rise.

A normal solar cell produces 0.5 V voltage, has bluish black color, and is octagonal in shape. It is the building block of a solar panel and about 36–60 solar cells are arranged in 9–10 rows to form a single solar panel. A solar panel is 2.5–4 cm thick and by increasing the number of cells, the output wattage increases.
