Does anyone have this solar panel?

[Chief Engineer]

Go to e-bay and search for "2.88 solar panel"

I am looking for an inexpensive solar panel for keeping batteries topped up

it looks rather tough...from the picture

thanks

That will only give you about 1/4 amp in the best of conditions.
Hardly enough to keep up anything bigger than a small car battery.

Even a small Group 24 battery would want a 0.5 to 1.0 Amp battery "maintainer".

this 2.88 Watt panel might deliver a maximum output of 0.2 Amps (200 milliamps, or smaller than my 250 mA cell phone charger) at 14VDC, whereas most cheap battery “maintainers” are often rated about 1.5 Amps.

Maybe he needs to keep a calculator battery topped off.

(just joking around... no offense intended, except toward the panel itself)

I appreciate all the replies......while I may know a great deal about
suck-squeeze-bang-blow....the electrical formulae I am a bit rusty on.

I always appreciate this board.

I'm using one of the VW solar panels you see on e-bay. I left the boat in September and will return next month. I'll let you know how it worked.

As promised...I am reporting the status of my 450 amp battery bank being left for 7 months with an inexpensive VW shipping solar panel I bought off E-Bay for $20. It is rated at 4 watts.
Upon arriving on 'Faiaoahe', I hooked up my A.C. and threw the charger on. It only climbed to just over 15 amps and only for 20 minutes before it settled down to zero.
Apparently the little charger did it's job keeping them topped off.
Please note...I cut off the little regulator and attached a couple of aligator clips and hooked directly to the battery.
