Hi, I am living in Melbourne and planning to install Solar for my house. My average daily usage is 21KWH for the month of July. I have received few quotes from solar company. The price mentioned below is after removing the state and federal rebate.

I prefer Goodwe inverters over Growatt and Jinko Panels, so my first pick would be option 2.

However, these prices are very low, so I would be very careful which company you choose and look at the company reviews. Did any of the companies quoting actually do a site visit and check your switchboard and roof for any shading issues? How did you get the quotes?
