I have been quoted the following by two installers in Victoria:
4.9 kw LG 350 W panels x 14 + Fronius Primo or SMA Sunnyboy inverter for $10.3 k
5.1 Sunpower 320 W panels x 16 + Fronius Primo inverter for $8.6 k
Our household consumption is very minimal, average daily usage is 5-6 kWh in summer period, it’s even less in other times of the year.
My property is north facing with tiled roof.
Both installers have recommended putting panels on east and west sides
Which one I should go for?
