Hi all,
I am simulating a building with PV generators, strangely I found that the annual total net purchased energy (258kWh) is not equal to annual total electricity demand (4717kWh) minus annual total energy generated on site through PV (4504kWh), i.e 213kWh.
Apologies if I am missing something in the documentation but I couldn't find an explanation for this. I would expect the following to hold true
Annual total net purchased energy = Annual total electricity demand - Total energy generated on site through PV
and therefore annual total energy generated on site to be 213 Kwh.
Many thanks
