Re: Recommended solar panel brand
As I understand it, series vs parallel is a trade off. In series, in full light, there is reduced impedance because of the higher transmission voltages to the MPPT ostensibly close to the batteries. In parallel, higher resistances( 3x) because 1/3rd the transmission voltage, but when shading one panel you still have 2/3 the amperage at the same voltage that you had with no shading.toggle quoted messageShow quoted text
So it’s a trade off. For us: we went with series installation as our plan was less time around other masts and more time in Anchorages and sailing. I’d love to see actual numbers.
Never sure I made the right choice, except I run the genny for water and laundry only now, so solar has been a big improvement over all.
Excuse the errors.
