solar australia newcastle
How much energy does a 1kW solar system produce with no shade?
It’s in newcastle new south wales Australia. Sydney answers would prob work
You haven’t given a tilt angle or direction (north etc). I’m going to assume that the solar panels are facing north, and on a 20 degree tilt. 30 degrees would be better but most modern rooftops are less.
Then, for Sydney you’ll get about 4 kilowatt hours per installed kilowatt of panels (with brand name inverters and panels).
