First of all, I'm very new to this software.
I'm trying to simulate PV production from my own weather file. It's a csv-file made in notepad that conatins
year,month,day,hour, GHI and DNI. The GHI-values are collected from a sensor, and the DNI values are calculated using the DISC model.
I'm only getting negative monthly production, no matter what size of the panels i choose.
EDIT: I have compared the DNI- data with data from an other city in my country (Bergen, Norway) from the SAM library. The data from Bergen gives complete different results (and off course positive production), but the energy from DNI is not extremely different( ~440kWh/year vs. ~ 380 KWh/year).
What can be the problem?
