I am about ready to add to my current 2 12volt panel system that has 260 watts and about 16.5 amps max. I can add one 12 volt panel to my existing system for 500 bucks for the panel. Then my 30 amp controller is maxed out.
The guys that put up my solar system 1 1/2 years ago tell me I should go with the new 36 volt systems. The new 240 watt panels are $360 each without install. Does anyone know anything about 36 volt systems vs 12 volt systems? I would have to get another controller, but I figure I can add 2 of the 240 watt 16 amp panels and have 45 amps max output. That should cover all my electric needs except air conditioning. Although I currently have a 2000 watt inverter that should power one air conditioner.
