TQ152 PVsyst Photovoltaic Software v4.1 April 2022 EHC
Approved Ruling:
NZGBC can allow the use of PVsyst instead of BRANZ Calculator to determine kWh/annum produced. However, to calculate the emissions offset please input this figure into the Energy Calculator Tab. Also, provide details of analysis to NZGBC after incorporating this calculation into the project. Additionally, to validate the chosen software is more accurate than the BRANZ calculator. It is advisable to show comparative result between BRANZ Calculator and PVsyst.
