I have a 12kw system which was starting to produce up to 65kwh a day with a max of 10kw about three weeks ago. However the next day it only hit 44kwh or so. I assumed it was just clouds or something. However, fast forward a few weeks and even on a cloudy day I would get much above the 44kwh, and my max output is under 7. I thought it might have been dirt, dust, and pollen as we are not too far from a freeways and home construction. However I washed them with a hose and a soft brush with only minimal improvement.
Any ideas on what could cause such a drop off? Anyway to look into this on my own?
