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-cell efficiency - Wikipedia

   en.wikipedia.org/wiki/Solar-cell_efficiency

   The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system. For example, a solar panel with 20% efficiency and an area of 1 m 2 produces 200 kWh/yr at Standard Test Conditions if exposed to the Standard Test Condition solar irradiance value of 1000 ...

4. Photovoltaic system - Wikipedia

   en.wikipedia.org/wiki/Photovoltaic_system

   A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...

5. Global Solar Atlas - Wikipedia

   en.wikipedia.org/wiki/Global_Solar_Atlas

   The Global Solar Atlas (GSA) is a free, online, map-based application that provides information on solar resource and photovoltaic power potential globally. It features the online interactive map tools, simplified photovoltaic (PV) power calculator, reporting tools and the extensive download section.

6. 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 ...

7. Shockley–Queisser limit - Wikipedia

   en.wikipedia.org/wiki/Shockley–Queisser_limit

   The limit is one of the most fundamental to solar energy production with photovoltaic cells, and is one of the field's most important contributions. [2] This first calculation used the 6000K black-body spectrum as an approximation to the solar spectrum.

8. Nominal power (photovoltaic) - Wikipedia

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

   Most countries refer to installed nominal nameplate capacity of PV systems and panels by counting DC power in watt-peak, denoted as W p, [4] or sometimes W DC, as do most manufacturers and organizations of the photovoltaic industry, such as Solar Energy Industries Association (SEIA), the European Photovoltaic Industry Association (EPIA) or the ...

9. Photovoltaics - Wikipedia

   en.wikipedia.org/wiki/Photovoltaics

   This represents 2% of worldwide electricity demand. More than 100 countries, such as Brazil and India, use solar PV. [106] [107] China is followed by the United States and Japan, while installations in Germany, once the world's largest producer, have been slowing down. Honduras generated the highest percentage of its energy from solar in 2019 ...
