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. Solar-cell efficiency - Wikipedia

   en.wikipedia.org/wiki/Solar-cell_efficiency

   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 W/m 2 for 2.74 hours a day. Usually solar panels are exposed to sunlight for longer than this in a given day, but the solar irradiance is less than 1000 W/m ...

4. 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.

5. Solar irradiance - Wikipedia

   en.wikipedia.org/wiki/Solar_irradiance

   The unit of insolation often used in the solar power industry is kilowatt hours per square metre (kWh/m 2). [12] The Langley is an alternative unit of insolation. One Langley is one thermochemical calorie per square centimetre or 41,840 J/m 2. [13]

6. Photovoltaic system - Wikipedia

   en.wikipedia.org/wiki/Photovoltaic_system

   Generated kilowatt-hour per installed watt-peak, based on average insolation for Japan (1500 kWh/m 2 /year), United States (5.0 to 5.5 kWh/m 2 /day), [133] and Germany (1000 to 1200 kWh/m 2 /year). A 2013 study by the Fraunhofer ISE concludes LCOE cost for a small PV system to be $0.16 (€0.12) rather than $0.22 per kilowatt-hour as shown in ...
