I bet the panel will probably put out more than 36w... in
perfect conditions (at noon, clean glass, clear sky, perfect orientation). But significantly less than that on average, since it will rarely be oriented toward the sun.
As a note: I did a simple test when I was playing with my
solar powered boat this summer: just washing a light coat of pollen/dust off the glass improved power output by 5%.

Good eye, Robert. That was a mistake on my part in the graph! I didn't start the x axis at 0:00, but should have - the axis was off by 0:15 relative to the points on the curve. Fixed.
PS: 30 mins gives
my setup +30F. YMMV! Results will definitely vary depending on engine/coolant mass, heater type etc.
PPS: I wouldn't worry much about mppt or what to do with your dump load. First make it work! Then make it better. :P
