Zero Battery Discharge Energy

[Aira Joie Mendiola]

Hello PVSyst Team and everyone,

 

Requesting for your kind assistance to explain why we obtained zero values for EBatDis for the months of June, July, August, and December? What does it implicate on our design (On-grid + PV + Battery)

 

Hoping for prompt response. Thank you.

With a PNom ratio of 1.25 you are at the limit of the overload.

The global yearly contribution of your peak shaving savings is    33.6 MWh / 18’930 MWh,  i.e. 0.18%, i.e. negligible.  This cannot motivate the expense of a Peak shaving storage.
During these months, you never attain conditions when the system output power exceeds the Power limit, so that you don’t have any peak shaving.
