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. TI-36 - Wikipedia

   en.wikipedia.org/wiki/TI-36

   TI-36 SOLAR was based on 1985 version of TI-35 PLUS, but incorporates solar cells. It addition to standard features such as trigonometric functions, exponents, logarithm , and intelligent order of operations found in TI-30 and TI-34 series of calculators, it also include base (decimal, hexadecimal , octal , binary ) calculations, complex values ...

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 ...

5. Nominal power (photovoltaic) - Wikipedia

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

   The nominal power of PV devices is measured under standard test conditions (STC), specified in standards such as IEC 61215, IEC 61646 and UL 1703. Specifically, the light intensity is 1000 W/m 2, with a spectrum similar to sunlight hitting the Earth's surface at latitude 35°N in the summer (airmass 1.5), the temperature of the cells being 25 °C.

6. Solar panel - Wikipedia

   en.wikipedia.org/wiki/Solar_panel

   Solar panels are also known as solar cell panels, solar electric panels, or PV modules. Solar panels are usually arranged in groups called arrays or systems . A photovoltaic system consists of one or more solar panels, an inverter that converts DC electricity to alternating current (AC) electricity, and sometimes other components such as ...

7. Thermophotovoltaic energy conversion - Wikipedia

   en.wikipedia.org/wiki/Thermophotovoltaic_energy...

   Solar TPVs are a source of emission-free renewable energy. TPVs can be more efficient than PV systems owing to recycling of unabsorbed photons. However, losses at each energy conversion step lower efficiency. When TPVs are used with a burner source, they provide on-demand energy. As a result, energy storage may not be needed. In addition, owing ...
