I was just thinking about the definition of SUN HOURS. Like, with my sun rise to sunset being

10:50 hours now, the total energy hitting a given panel might be equivalent to 5 hours of perfect

sun noon. So then its 5 SUN HOURS that day, location, and alignment.

Working this backwards, harvesting 110 KWH divided by 15 KW inverter maximum (clipping)

level, gives 7.33 equivalent SUN HOURS. The idea of course is to stretch the sun day by adding

panels directly facing the rising & setting sun. Comparing this to the basic sun hours could be

a multiplying factor for the panel arrangement. Probably the factor doesn't have a name? I'm

still looking for a tool to use, to predict this factor. Bruce Roe
