That goes double if you get any fog or mist in the morning which will reduce the efficiency of the east facing panels.
I figured i d have to get tigo or enphase.
Jim panels on a south facing roof even laid flat will almost invariably produce more electricity that east facing panels.
We are looking at installing a 5kw system lg neon 2 panels and fornius inverter on a double storey house and had initially thought of splitting the panels between our north east and west facing roofs so that we got production over most of the day 8 panels north 4 east and 4 west.
