How to set the P value

[klb]

I need assistance on how to set the P value in the latest version. I cannot find the bankability option in the financial analysis.

I want to set it to P90 since the default value is P50.

Thank you.

Hello klb,

Thank you for your inquiry.

Make sure that you select ‘grid-connected PV system’ (without electrical appliances), then the bankability option will be displayed in the financial analysis.

I am aware of it. But, why I can't edit it on "Grid Connected PV System with Electrical Appliances"? The difference in the yield output is significant when we want to set the P value to P90. P50 is very optimistic even we try to increase the losses so that we can simulate a very conservative yield.

Hello klb,

Thank you for your inquiry.

Unfortunately, the bankability option is only available for the full feed-in concept.

Hello,

I'm sad hearing that since we offer PPA for our customers in C&I industries. We use their consumption to know if the yield is 100% consumed or not so we can adjust our design capacity for the offer. If we use P50 we have a very optimistic yield. Are there other way to set the parameters near P90 values? I have mentioned I tried to increase the losses but the difference in yield with P90 is still significant and I want to defend it to the top management.

Thank you.

Hello klb,

Under ‘Options’ --> ‘Project Options’ --> ‘Simulation’ you can define more losses (e.g. losses due to deviation from standard spectrum, power losses resulting from a drop in voltage at the bypass diodes, power losses resulting from mismatching or reduced yield, output losses due to soiling):
