4.8kWh 12x panels, it's actually 12x415W (4980kW theoretically) assuming what they say they have put on the roof as what they say they are, not been up to look TBH
i did check the panels they were fitting to mine before they put them up there lol......i got 8 x 410w panels, so 3.28kw.
We are up over 5.1kwh now....i would say maybe around 3hrs of decent sun left ( maybe lol )
