It accounts for the various causes of a panel not producing the power rating on its nameplate.

Derating factor solar panel.

Tools such as solar pathfinder may be used to determine a derate factor for. Once we know the temperature coefficient the installation type and the ambient temperature of a location then we can calculate the temperature derating of the solar panel. Shading derate factor pvwatts definition. This means that if a solar panel has a capacity factor of 25 it s average energy output will be 25 of what it was designed to achieve e g a 100 watt solar panel with a capacity factor of 25 has an average energy output of 25 watts.

For the default value of 1 00 pvwatts assumes the pv modules are not shaded. The photovoltaic pv derating factor is a scaling factor that homer applies to the pv array power output to account for reduced output in real world operating conditions compared to the conditions under which the pv panel was rated. The default derating factor on the solar goods diy solar calculator is 83 percent. Solar panel derating the 0 7 above is a rough derating factor.

In the above scenario if the ambient temperature is 28 c the panel will lose 13 2 of its output. Use the derating factor to account for such factors as soiling of the panels wiring losses shading snow cover aging and so on. A temperature derating can be applied as follows. The derate factor for shading accounts for situations when pv modules are shaded by nearby buildings objects or other pv modules and array structure.

While many of the derate factors may be unavoidable you can take steps to reduce your system losses. For most photovoltaic systems this figure provides a reasonable estimate for determining energy production. The derate factor for the pv module nameplate dc rating accounts for the accuracy of the manufacturer s nameplate rating. Some systems use mirrors to shine more light onto the same panel to increase the power output.

These include but are not limited to. Field measurements of pv modules may show that the pv module powers are different than the nameplate rating or that they experienced light induced degradation upon exposure even crystalline silicon pv modules typically lose 2 of their initial power before power stabilizes after the first few hours of exposure to sunlight.
