2. Potential-induced degradation - Wikipedia

   en.wikipedia.org/wiki/Potential-induced_degradation

   In 2007, PID was reported in a number of solar panels from Evergreen Solar (Photon 1/2008 and 8 /2008). In this case, the degradation mechanism occurring in photovoltaic modules containing the more common front junction (n+/p) crystalline silicon solar cells when the modules were in negative voltage potential with respect to ground.

3. Polarity symbols - Wikipedia

   Diagram showing positive tip polarity on the left and negative tip polarity on the right. To read diagram: The center positive drawing on the left indicates that the center (also known as the tip) of the output plug is positive (+) and the barrel (ring) of the output plug is negative (−). Center positive symbol Center negative symbol

4. Solar azimuth angle - Wikipedia

   en.wikipedia.org/wiki/Solar_azimuth_angle

   The following formulas can also be used to approximate the solar azimuth angle, but these formulas use cosine, so the azimuth angle as shown by a calculator will always be positive, and should be interpreted as the angle between zero and 180 degrees when the hour angle, h, is negative (morning) and the angle between 180 and 360 degrees when the ...

5. 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 ...

6. Photovoltaics - Wikipedia

   en.wikipedia.org/wiki/Photovoltaics

   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 2 for most of the day. A solar panel can produce more when the Sun is high in Earth's sky and produces less in cloudy conditions, or when the Sun is low in the sky. The Sun is lower in the sky in the winter.

7. 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 ...
