I v curve in solar pv february 27 2019 february 27 2019 solarpost 1 comment i v curve in solar pv iv curve solar panel solar pv solar pv cell solar energy or pv technologies which harness the sun s energy to generate electrical power are one of the fastest growing sources of renewable energy in the market today. The curve looks like a seated person s leg. For the purpose of the electrical characteristics of a solar cell the inside of that black box can be described by an electric cicuit with only 4components. The working of a solar cell solely depends upon its photovoltaic effect hence a solar cell also known as photovoltaic cell a solar cell is basically a semiconductor device.

A typical i v curve for a 12 v module is shown at fig. A solar module can be seen as a black box that with two connectors producing a current i at a voltage u. Solar cell is the basic unit of solar energy generation system where electrical energy is extracted directly from light energy without any intermediate process. Knowing the electrical i v characteristics more importantly p max of a solar cell or panel is critical in determining the device s output performance and.
