Important parameters of photovoltaic panels
A solar cell is a semiconductor device that can convert solar radiation into electricity. Its ability to convert sunlight into electricity without an intermediate conversion makes it unique to harness the available solar energy into useful electricity. That is why they are called Solar Photovoltaic cells. Fig. 1 shows a typical solar.
The sunlight is a group of photons having a finite amount of energy. For the generation of electricityby the cell, it must absorb the energy of the.
The conversion of sunlight into electricity is determined by various parameters of a solar cell. To understand these parameters, we need to take a look at the I – V Curve as shown in.
A wide variety of solar cells are available in the market, the name of the solar cell technology depends on the material used in that technology. Hence different cells have different cell.The important parameters for evaluating solar cells are their efficiencies, bandwidth, tolerance to environmental conditions, and robustness to the incident angles of incoming waves [1, 2].

There are three important parameters in solar photovoltaic (PV) panel performance, namely maximum output power, short-circuit current, and open-circuit voltage.
These parameters include reference yield, final yield, performance ratio, capacity utilization factor, and system efficiency.
PV cell parameters are usually specified under standard test conditions (STC) at a total irradiance of 1 sun (1,000 W/m2), a temperature of 25°C and coefficient of air mass (AM) of 1.5.
