6 FAQs about [What is the correction factor for photovoltaic panels ]

What factors affect the performance of a photovoltaic panel?

There are a number of factors which can affect the actual performance of a photovoltaic panel causing it to vary away from its theoretical value, and one of those is Temperature Coefficient, or more specifically Open-Circuit Voltage Temperature Coefficient given in either a percentage of V per degree C, ( %/ C ) or volts per degree C, (V/ C).

How does temperature affect PV voltage?

This means that for every degree change in temperature, the module’s Voc will change in the opposite direction by 0.35%. For example, if the PV module got colder by 1°C, the PV voltage would increase by 0.35%. This specific value happens to be common for crystalline PV modules. There are two additional points to make on TC values.

How does temperature affect the efficiency of PV cells?

Software is normally used for the calculation of this or the use of correction coefficients from the concerned location. As the temperature of PV cells increase, the output drops. This is taken into account in the overall system efficiency (η), by use of a temperature derating factor ηt and is given by:

What fill factor should a commercial PV cell have?

As a general rule, commercial PV cells will have a fill factor greater than 0.7. Cells with factors less than this are not really recommended for practical application in larger electricity generation projects. A PV module's I-V curve can be generated from the equivalent circuit (see next section).

How do I know if a PV module is compatible with voltage specs?

This will ensure the PV module is compatible with the system's voltage specs. The common practice is to compare the PV module's Temperature Coefficient against the lowest recorded temperature for the area. However, solar designers have realized that using 100-year record-low temperatures result in overly conservative designs.

Why is variable output voltage important in PV design?

The variable output voltage is an important factor for both cold temperatures and hot temperatures, and both must be considered during system design. When temperatures are cold, the PV module will increase in voltage. When it is hot, the module’s voltage will drop. Both are simple and unavoidable facts in PV design.
