I have one 240W maximum power (Pmax) Sharp brand solar panel.
My average annual DNI is 5791 Wh/m2/day.
In December it drops to 2925 Wh/m2/day.
In July it is 8820 Wh/m2/day.
How many Watts (on average) will this panel produce per day based on my average annual, and my average min and max?
What is the formula I should use for a basic calculation? (is it DNI Wh/m2/day * Pmax? Do I need to adjust it because the panel is 2 meters by 1 meter?) Is there any other information I will need to calculate it?
Also, I’m not concerned about loss and inefficiency at this point, so let’s just assume I have everything adjusted as perfectly as I can for a stationary setup facing south.

Well if this is for you own information, I would suggest you use the average and since you have a 2×1 m panel, you have 2m2 fo factor that in with the area.
If you are doing it as a school assignment, then the caluclations are much more complex.
Remember every day will be different because of cloud cover etc so no sense in getting too detailed.
