Export of solar production in watts (minutes)

[MEURVILLE]

Hello,

Does PVSYST allow the export of power (kW) every 30 minutes?

I know it is possible every hour, but is 30 minutes possible?

The results export is restricted to the same time step as the simulation, which is set to 1 hour.

Smaller time steps will be available once the sub-hourly simulation is.

What is the sub-hourly simulation ?

Sub-hourly simulation is a simulation with a time step lower than 1 hour.

It may be useful to correctly account for non linear phenomenon such as clipping and curtailment.

It is currently not directly available in PVsyst, even though workaround exist to run pseudo sub-hourly simulation https://www.pvsyst.com/wp-content/pdf-tutorials/pvsyst-tutorial-v8-pseudo-sub-hourly-simulation-en.pdf or to have a better clipping correction estimation https://www.pvsyst.com/help/physical-models-used/grid-inverter/subhourly-clipping-correction.html?h=clipping. In both case, sub-hourly weather data is necessary.
