  2. 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.

  3. Solar-cell efficiency - Wikipedia

    [1] [2] In a high-yield solar area like central Colorado, which receives annual insolation of 2000 kWh/m 2 /year, [3] a panel can be expected to produce 400 kWh of energy per year. However, in Michigan, which receives only 1400 kWh/m 2 /year, [ 3 ] annual energy yield drops to 280 kWh for the same panel.

  4. Solar irradiance - Wikipedia

    en.wikipedia.org/wiki/Solar_irradiance

    Total solar irradiance (TSI) is a measure of the solar power over all wavelengths per unit area incident on the Earth's upper atmosphere. It is measured facing (pointing at / parallel to) the incoming sunlight (i.e. the flux through a surface perpendicular to the incoming sunlight; other angles would not be TSI and be reduced by the dot product ...

    [24] [25] In a high-yield solar area like central Colorado, which receives annual insolation of 2000 kWh/m 2 /year, [26] a panel can be expected to produce 400 kWh of energy per year. However, in Michigan, which receives only 1400 kWh/m 2 /year, [ 26 ] annual energy yield drops to 280 kWh for the same panel.

  6. 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 ...

  7. 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.
