March 28, 20206 yr Hi thanks again for the great forum. a quick Q, and i'm a real novice. on average, at peak sunny conditions, how much KW can I expect from 12 340W monochristaline panels, lined in 3 paralel blocks of 4? I know its dependent on the weather and position of the panels, but just want an average to estimate.

Sometimes higher and sometime lower, but in that region. (Peak as in just before 12 midday) It will start at a few watts as the sun rises and increase to peak production and then start decreasing till sun under.
March 29, 20206 yr Author okay, that's good. I have been getting about 3100 W at peak, drops quite drastically, my norm is around the 1600-2000W.
March 29, 20206 yr For some useful info on solar panel performance, based on installation angle, orientation and your location, see https://www.pveducation.org/pvcdrom/properties-of-sunlight/solar-radiation-on-a-tilted-surface Edit: This page is probably more useful - https://www.pveducation.org/pvcdrom/properties-of-sunlight/calculation-of-solar-insolation Edited March 29, 20206 yr by NigelL
March 31, 20206 yr Reading up allot on “what can be expected” from your PV array, there is a school of thought that says rather than worrying about peak production, rather design to match your load. What is your orientation of your 3 strings? Will like to know what people think about east or west orientation rather than all north?
