I am looking at getting several panels
and I have a choice of two brands.
Both are tier 1 companies.
The ones on the left (Jinko) I can get for 2nd hand with 9.5 years of the 10 year warranty still in play.
They are around 30% cheaper than the ones on the right and specs (to me) look to be almost the same.
The cost saving will allow me to buy more panels
and more batties.
The ones on the right (Winaico) are new, but more expensive therefore I will only buy what I need at the moment.
The question I have is the Winaico's are being described on the quote as 24v panels, is there such a thing?
bank is 12v batteries wired up as 24v, so wouldn't the solar panels
be 12v also and wired the same way?
