Hi! I'm trying to add a photovoltaic system to my model using OpenStudio(version 1.10.0) so I can obtain the Kwh for a runperiod simulation. What is the way you advise to do it? I add the "Add Simple PV to Shading Surfaces By Type" measure but I'm not seeing how we can specify the power of the PV system and other important informations like inverters and electrical storage. Where I can find information about how to add a PV system to a OS model? Thank you

The measure you are looking at is an old EnergyPlus measure, that pre-dates PV support in OpenStudio. That is fine, it still works, but this post shows how to add PV directly in the SketchUp plugin .

In both cases PhotovoltaicPerformance:Simple is used.

If you want to change the inverter efficiency you can change this string or expose an argument for it in the existing measure you are using.

    ElectricLoadCenter:Inverter:Simple,
    Simple Ideal Inverter,   !- Name
    pv_script always On,               !- Availability Schedule Name
    ,                        !- Zone Name
    0.0,                     !- Radiative Fraction
    0.95;                     !- Inverter Efficiency
    "

Battery storage isn't in OpenStudio, so you would need an EnergyPlus measure for that.

Thank you for your answer David Goldwasser! The measure for the battery storage exists at the moment? Is there a way we can control the direction and inclination of the PV panels in OS?

I'm not aware of a battery measure. The Generator:Photovoltaic object is associated with a shading or heat transfer surface, so the direction and inclination of that surface is used. You can set the fraction of that surface to have panels, and what the efficiency of the panels should be.
