  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

    The fill factor is directly affected by the values of the cell's series, shunt resistances and diodes losses. Increasing the shunt resistance (R sh) and decreasing the series resistance (R s) lead to a higher fill factor, thus resulting in greater efficiency, and bringing the cell's output power closer to its theoretical maximum. [22]

  4. Present value - Wikipedia

    en.wikipedia.org/wiki/Present_value

    With Present Value under uncertainty, future dividends are replaced by their conditional expectation. Traditional Present Value Approach – in this approach a single set of estimated cash flows and a single interest rate (commensurate with the risk, typically a weighted average of cost components) will be used to estimate the fair value.

  5. 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 ...

    en.wikipedia.org/wiki/Air_mass_(solar_energy)

    For example, when the sun is more than about 60° above the horizon (<30°) the solar intensity is about 1000 W/m 2 (from equation I.1 as shown in the above table), whereas when the sun is only 15° above the horizon (=75°) the solar intensity is still about 600 W/m 2 or 60% of its maximum level; and at only 5° above the horizon still 27% of ...

  7. Capacity factor - Wikipedia

    en.wikipedia.org/wiki/Capacity_factor

    The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. [1] The theoretical maximum energy output of a given installation is defined as that due to its continuous operation at full nameplate capacity over the relevant period.

  8. Copper indium gallium selenide solar cell - Wikipedia

    en.wikipedia.org/wiki/Copper_indium_gallium...

    CIGS is a I-III-VI 2 compound semiconductor material composed of copper, indium, gallium, and selenium.The material is a solid solution of copper indium selenide (often abbreviated "CIS") and copper gallium selenide, with a chemical formula of CuIn x Ga (1−x) Se 2, where the value of x can vary from 1 (pure copper indium selenide) to 0 (pure copper gallium selenide).

  9. Pressure–volume diagram - Wikipedia

    en.wikipedia.org/wiki/Pressure–volume_diagram

    A PV diagram plots the change in pressure P with respect to volume V for some process or processes. Typically in thermodynamics, the set of processes forms a cycle, so that upon completion of the cycle there has been no net change in state of the system; i.e. the device returns to the starting pressure and volume.
