Basic Questions on Solar Install
I'm finally getting rid of the generator and looking to install solar. Right now I have a 2000W inverter and 450AH of lead acid batteries. I'm looking at installing (3) 175W panels and an MPPT charge ...

BFL13,
Adding a panel makes up for not tilting. That works for series and parallel.
Series is better for wire size and a titch early and later in the day production of power. Probably an insignificant additional amount of energy production. But the savings on line losses are significant.
My ideal system would be 48 volts with 1600 watts of panels and 200 amp-hours (at 48 volts) of SiO2 batteries.
Adding an extra panel won't do much for shading unless there are diodes between every cell. So far as I am aware, only Unisolar did that--and they are long since gone. My panels are 15 years old now and still doing 17 amps (~200 watts), if the battery bank is hungry, or I turn on a heavy draw item.
