Wowww thats amazing around 7.2Kwh per Kw installed!!
I made 2.8Kwh per Kw installed today a record for this year so far
Mine is lower partly because I dont export so everything is used in the house.
Peak power today was 0.9Kw per Kw, this depends on the load offered at the best time of day, it sometimes hits 1.05Kw.
I agree on spring sunshine, again my panels are about 52degrees that also happens to be my Lattitude
Clearer air, no high haze this time of year and no airborn dust from the feilds, as for pollution the surrounding pig farms dont seem to affect solar as much as my nose hahaha
About the same conditions here Hero
and yes the Axitec panels Pmpp increases 0.45% every degree C lower.
