2. 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 ...

3. Nominal power (photovoltaic) - Wikipedia

   en.wikipedia.org/wiki/Nominal_power_(photovoltaic)

   The highest power thus measured is the 'nominal' power of the module in watts. This nominal power divided by the light power that falls on a given area of a photovoltaic device (area × 1000 W/m 2) defines its efficiency, the ratio of the device's electrical output to the incident energy.

4. 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 ...

5. Solar irradiance - Wikipedia

   en.wikipedia.org/wiki/Solar_irradiance

   Radiant energy may be developed for solar power generation. Solar irradiation figures are used to plan the deployment of solar power systems. [39] In many countries, the figures can be obtained from an insolation map or from insolation tables that reflect data over the prior 30–50 years. Different solar power technologies are able to use ...

6. Solar energy - Wikipedia

   en.wikipedia.org/wiki/Solar_energy

   Solar energy is the radiant energy from the Sun's light and heat, which can be harnessed using a range of technologies such as solar electricity, solar thermal energy (including solar water heating) and solar architecture.
