I've been reading up about mixing different sizes and specs of panels and getting fairly confused.
I've already got a 100w 12v panel, but want to upgrade to a total of around 800w. I'd also add a new MPPT.
If I buy more 12v panels and want to run everything through the same SCC, should I buy the exact same model of panel as I already have- or does it not really matter so long as they are nominally 12v?
I could also not worry about my existing panel and buy a couple of big 32v 300w panels, cheap as chips, but the cost savings evaporate when I try to get them delivered. Lots of smaller 12v panels works out exactly the same cost to me, and I would get more shade tolerance, but it also seems to work out a bit bulkier and heavier overall. Not a deal breaker.
Any thoughts appreciated- I'd like to get my order in ASAP since they'd be coming from Germany to the UK and after the end of this year Brexit will very likely complicate that sort of transaction.
