Question:
When filling out the Sustainability Victoria spreadsheet there’s 2 ways to enter the amount of solar energy generated by the design, either have the spreadsheet directly model it, or use the NatHERS Tool output to enter directly.
My concern is that these two calculations are vastly different!
Response:
In this case the big difference is I think mainly due to the curtailment. If you add 14477 + 4299 it gets a lot closer to the spreadsheet table.
Note, I assume your all electric home will be 3 phase. If so then the curtailment level to set is 15kW (not 5kW).
The right figures to use are your HERO ones.
