[Sub-arrays & economic evaluation]

Hi,

I'm using PVsyst version V6.78. I'll send the project as you wished.

[Sub-arrays & economic evaluation]

Hello,

When I use sub-arrays the economic evaluation tool only takes into account the panels of the first sub-array (100) but takes into account the number of supports for the whole system (810). How can I make it so all the panels and inverters are calculated into the investment?

[Economic evaluation & self-consumption]

Before analyzing the economic evaluation, please analyze first the energy output of your simulation.

I don't understand well what you have specified on your CSV file: with CSV reading, PVsyst only accepts hourly consumption values, not daily values.

If you want to create a PV system ensuring 100% self-consumption, it should be of sufficiently low power for never exceeding the User's needs, even by clear sky conditions.

 

Thanks, Andre.

I realized that the self-consumption has to be in hourly consumption values, like you said. I had the self-consumption in daily consumption values and that's why in the economic evaluation all the generated power was on the "sold energy to grid" row.

[Economic evaluation & self-consumption]

Hello, I am trying simulate a situation where the "self-consumption" should be 100% and "sold energy to grid" should be near 0%. I have created a CSV-file of the daily user's needs and used that in the "self-consumption" of the Main parameters.

So why is the "self-consumption" in Economic evaluation 0 kWh/year and the "Sold energy to grid" basically all produced energy, and how do I change it? It messes up the Financial results, because PVsyst thinks I want to sell all the produced energy.

Thanks
