I can see a place for 7 from the picture of babs AS.
I also have to ask the 4@100 watt panels trying to keep up how much battery capacity??
what is rule of thumb on solar. I have been tying to get a handle on that.
In the 8 panel deal lewster was talking about they were keeping up some 600 amp/h of battery so just figuring 100 watt panels you are over watts to amp/h some what.. is the "golden rule" double watts to amp/h or how is that figured.
It really depends on your usage of the power to get it right, but the 'rule of thumb' that many follow is 1 watt of solar array for each amp/hour of battery capacity.
You can, of course, have as many panels as your roof can hold and have extra solar capacity, which will provide more charging amps to the batteries and keep them at a higher state of charge and provide for faster recharge cycles.
