Ryan, I started doing some testing with our solar panel
thay may help you.
I started with a fully charged battery
on a partly cloudy day.
Our trailer has all LEDs.
I turned on one LED and the solar panel
supplied 0.2 amps. I turned on 4 LEDs and the solar panel
supplied 0.8 amps.
Since the battery
started fully charged the solar
panels only supplied replacement current, the amount used by the LEDs.
I tuRned off two LEDs and it dropped back to 0.4 amps.
I then turned on the water. pump to bring the water system up to pressure. The solar
panels jumped from supplying 0.4 amps to supplying 1.2 amps. It supplied 1.2 amps for less than a minute and returned to 0.4 amps, the load of the two LEDs.
Obviosly LEDs draw little and though the water pump draws a lot, generally it doesn't run very long.
The pump probably ran for 10 seconds and the panels provided 1.2 amps for 45 seconds.
With a generally partly cloudy day our two solar
panels, two forty watters seem to be peaking at 36 watts.
I determined this by turning on the fridge
to 12 volts dc. Ivcan see the fridge
on 12 volts pulls more power than the panels can supply, gradually draining the battery
. With the fridge
running solar panel output has been between 2 and 3 amps, 24 to 36 watts.
Of course we never run our fridge on 12 volts but it's good exercise for the panels.
