One thing I have to do on every single project here in the UK is add solar PVs, and Archicad does have a Library object that is pretty good.
However, what is always useful is the ability to quickly calculate the entire area of panels, and calculate an approximate output. Obviously output varies on angle orientation and location, but the range of output within a small geographical area is not that big, enabling a meaningful approximate calculation to be derived.
The benefit of this is that it allows us to roughly work out what sort of PV area we need for any given project. The building services engineers will be able to provide estimates of heating/cooling load and energy requirements, so at an early stage in design we can get an idea of whether net zero carbon is likely to be achievable, and if so, whether we need PVs in places other than the building roof.
The current object Solar Photovoltaic Panel 25 is pretty good, but seems to be a derivation of the Solar Collector Flat Plate 25 object. These are some of the object properties:
Note the FM_HeatOutput property. This is what you would expect with a solar collector. With a PV panel you would expect a power output property.
I would also expect to see a functioning area parameter that allows us to calculate the output in a schedule.
There is one there:
but it has no data.
the Parameter script includes this:
if FM_HeatOutput_unit = `Btu/hour` then
if FM_RefrigeratingOutput_unit = `Btu/hour` then
if FM_PowerConsump_unit = `W/ft2` then
That's clearly not right for a photovoltaic panel.
I've tried to open it to see if I could modify it to add an area calculation but the 2D and 3D script dialogs are blank.
We can wait for GS to update this (I reckon it's maybe 10 minutes for someone like Peter 😉) or we can do it - assuming it isn't locked.
