Use this component to define simplified Photovoltaics crystalline silicon (c-Si) module settings.
If nothing inputed, the following PV module settings will be used by default:
- module material: crystalline silicon (c-Si)
- mountType: Close (flush) roof mount
- moduleEfficiency: 15%
- temperatureCoefficient: -0.5 %/C
- moduleActiveAreaPercent: 90%
If you would like to use a thin-film module, then use the thin-film module from "Import Sandia Photovoltaics Module" or "Import CEC Photovoltaics Module" components.
Also for choosing a specific module, not a simplified one, use one of those two components as well.


Mount TypemountType_Mounting type (configuration) of a module. There are three of them: - 0 = Insulated back (pv curtain wall, pv skylights, BIPV installations with obstructed bakside airflow) 1 = Close (flush) roof mount (pv array mounted parallel and relatively close to the plane of the roof (between 5 and 15 centimenters)) 2 = Open rack (ground mount array, flat/sloped roof array that is tilted, pole-mount solar panels, solar carports, solar canopies, BIPV installations with sufficient bakside airflow) - If not supplied, default type: "Glass/cell/glass, Close (flush) roof mount" (1) is used.Goo
Module EfficiencymoduleEfficiency_The ratio of electrical energy output from the PV module to input solar energy from the sun. Current typical module efficiencies for crystalline silicon modules range from 14-20% - If not defined, default value of 15(%) will be used. - In percent (%).Goo
Temperature CoefficienttemperatureCoefficient_A coefficient which accounts for the percentage the solar module's DC output power decrease/increase for every degree Celsius the solar cells temperature rises above/below 25C. - In general it ranges from -0.44 to -0.5 for crystaline silicon modules. - If not supplied, -0.5 will be used as a default. - In %/C.Goo
Module Active Area PercentmoduleActiveAreaPercent_Percentage of the module's area excluding module framing and gaps between cells. - If not supplied, default value of 90(%) will be used. - In percent (%).Goo
