2. Solar-powered calculator - Wikipedia

   en.wikipedia.org/wiki/Solar-powered_calculator

   Solar-powered calculators are hand-held electronic calculators powered by solar cells mounted on the device. [1] They were introduced at the end of the 1970s. [2]Amorphous silicon has been used as a photovoltaic solar cell material for devices which require very little power, such as pocket calculators, because their lower performance compared to conventional crystalline silicon solar cells is ...

3. Solar charger - Wikipedia

   en.wikipedia.org/wiki/Solar_charger

   Solar cell phone charger. Solar cell phone chargers use solar panels to charge cell phone batteries.They can be used when no electricity supply is available—either mains or, for example, a vehicle battery—and are sometimes suggested as a way to charge phones without consuming mains electricity, unlike electrical cell phone chargers.

4. Panel generation factor - Wikipedia

   en.wikipedia.org/wiki/Panel_generation_factor

   Panel generation factor (PGF) [1] is used while calculating the size of solar photovoltaic cells. It is a varying factor depending upon the climate of the site location (depending upon global geographic location). For example, in Thailand it is 3.43, in EU countries it is 2.93, etc. This factor is used in calculation of "Total Watt-Peak Rating ...
