    Any easy way to see if panel or 2 not producing? Seem to be down a bit for this weather. Have 10 panel and 8 panel string all south. s

    Should solar current be higher if solar voltage is higher? Seems to be lower current on string 1 but higher voltage.

    It's August, welcome to autumn (in PV terms)

    Days are shorter, it's more comparable to April. But warmer.

    Voltage should be different as you have different numbers of panels. But current should be similar-ish, which it is.

    Voltage should be the same as panels VMax x number of panels.

    Cheers man, yeah was thinking it would be like May on the graph but ya April makes more sense now I think of it. Lower amps but higher voltage for larger string was confusing me.

    Even a bit less than April due to heat lowering voltage from the panels
