[QUOTE="condor22, post: 619758, member: 1932"] I've noted this before - On low voltage, low wattage solar systems i.e. 100-200W, connecting parallel or series makes little difference to output. The only real world benefit is when you double voltage you reduce amps and can use thinner wire. Or, use the same wire and reduce voltage drop. In the 1-200W 12V range even here in most setups, not a big issue. I have a personal dislike of series panel connections when only 2 panels are used. If one panel, or wire in the system fails, you lose the lot. With parallel if one panel or it's wires fail, the other is still giving 100% of its output, or 50% of normal. [/QUOTE]
