Electrical Effect in Simulation - Unlimited Shades

[Michalis Angeli]

I have a project that has orientation unlimited shades, i would like to ask, if it is nesecary to check the option use electrical effect in simulation, and i would like to explain me what are these parameters.

Thank you!

Hi, yeah, it is recommended to use the electrical effect functionality. Indeed, it is only with it that you can fully take into account the effects of shadings and mismatch caused by shadings.

The width of the PV cell should be the width in the height of the table. For example, for an 9 cm by 18 cm cell, in a half-cut module in portrait, the relevant height is 9 cm.

The number of modules is an old name for this parameter. Now it is best read as “number of partitions in the height of the table”. https://www.pvsyst.com/help/shadings_partitioninstrings.htm
