PVsyst simulation using spectral irradiance datasets


Recommended Posts


I would like to know if it is possible to use PVsyst for modeling PV plant outcome based on spectral radiance datasets. Usually, we use broadband irradiation datasets. PVsyst is affecting a spectral correction model to correct this data in order to get the part of the radiation that can actually be used by modules. Therefore spectral mismatch is a source of uncertainty. In order to limit uncertainty of modeling, we would like to know if is is actually possible to use data registered with a calibrated PV Reference Device in PVsyst. Do you agree on the fact, that overall uncertainty should be lower?

Tank you for your answer.

In the present time, PVsyst performs an irradiance correction for amorphous modules only.

Spoectral effect is usually admitted as rather low in yearly simulations for crystalline modules.

We will probably develop a possibility of taking a spectral correction into account in a next version, but not before several months. This is not in our first priorities.

By the way such a tool will deal with spectral corrections models (as a function, for example, of the water contents of the amosphere).

Now for the use of a reference cell, please see our FAQ For Meteo measurements, should we use a pyranometer or a reference cell ?
