Not the best shots, but we can see the basics.
Each panel set gets a meter so I can tell at a glace if one of them has quit or has a problem.
In this case the top meter's panels are starting to get shaded - cutting down on the power I can get out of them (they were all within 30 watts at noon.)

One problem with any past solar influx data is that the weather has been shifting on us a bit.
Even if the data is good I'd suggest going 'more' than you think you need rather than less - unless it'll kill the budget - in which case get what you can while leaving room to add to the system at a later date. If possible get the biggest solar controller and inverter that you think you will need and leave space/connections for adding extra batteries/solar panels as you find you need them. (in my case I can add another four-set of batteries and two more four-sets of panels to my current setup without needing another controller (the controller is an 80 Amp, so six sets of panel at max sun is only 75 Amps in - I've seen just under 49 amps in on my four sets of panels.)
(and I am very seriously thinking of adding a bit more to my system!)
Drop me a note if you want more info (not that I'm no expert or nothing - I just play with stuff! )

I'll keep your generous offer in mind; thank you very much. I have a home now (just waiting for conditions to clear), and it's a bungalow, with a decent amount of roof space. Probably be next year before I get into really seriously looking at it, so will keep these faved for future reference.
