Best answer


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.

  • What is the PV derating factor and how is it used?

  • 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. Use the derating factor to account for such factors as soiling of the panels, wiring losses, shading,…

  • How do you use the derating factor to model solar panels?

  • Use the derating factor to account for such factors as soiling of the panels, wiring losses, shading, snow cover, aging, and so on. If you choose not to explicitly model the effect of temperature on the PV array, include temperature-related effects in the derating factor.

  • What is a DC to AC derating factor?

  • The DC to AC derating factor takes all of the potential environmental and system losses and adds them up into one percentage factor. This percentage indicates the overall efficiency of the PV module. The National Renewable Energy Laboratory breaks down how each derate factor affects the energy output of a photovoltaic system.

  • What factors affect the wattage of a solar panel?

  • But real life is not like these test conditions, and several factors 鈥?called derate factors 鈥?can affect how many watts of power a solar panel actually will produce. Some derate factors, such as shading, are environmental. Others, including wiring, connections and inverter losses, have to do with your DIY solar energy system components.
