Could you explain more on what you mean?
Sorry for the lack of details & I see I made some mistakes.
As in house maximum & average energy requirements, there is demand factor and diversity factor as defined in the NEC.
For example, our house uses 24 kw max [virtually never] and 1 kW average, even though we have 200A [48 kw] service.
Now on to your specifics, somewhere in here I thought I saw 300w but now it seems your power source is 330 x 2 = 660w.
So, 660w on for 5 hrs of full sun [21% of 24 hours] is 3,300 watt-hours.
Assuming perfect energy storage, you could have a 3,300 watt load on for 1 hour, 4% of 24 hours.
With imperfect storage you’d get less power for 1 hour or more power for less than 1 hour.
I can’t do the finer points of solar but I hope I can find some of the limits of what’s practically possible, using my spreadsheet [posted in another thread].
Determining the optimum design center value
[most kw for least $ for longest service lifetime]
for a system like this is beyond me, but this forum provides good practice & rules for zeroing in on an optimum.
Thanks for asking.
