the problem of discontinuity in simulation

[lhr]

Dear pvsyst team,

            How to solve the problem of discontinuity in simulation？

[Michele Oliosi]

In recent versions of PVsyst, nominal array energy balance errors are caused by the PAN file definitions.
Whenever the one-diode model parametrization does not reproduce the nominal rating of the module, the issue will reflect at the level of results via this warning.
I encourage you to open the module definitions, and observe the different discrepancies.

Note that generally the fit cannot be exactly right between both values. Insignificant differences are no problem. The problematic case is whenever the difference between the two values become important.
