I thought that was factored in when he talked about 3 full-hours of 200W across the full day? The day in Australia is certainly longer than 3 hours, so I figured that accounted for panel inefficiencies, indirect sunlight, and other such things. But could be wrong. Not sure how the 3 hours was calculated, but I am sure some solar calculators will take your location, average annual sunlight, efficiency and spit out an "effective daily solar hours" value that can be multiplied by the indicated solar panel wattage.

3 hours comes from averaging the daily power generation my Victron MPPT reports. I’m using a 200 watt panel and it reports and average of 600Wh since I set it up a month ago.

Even better than a calculator - it's your actual experience ;)
