@hantrongtai1,
Han sure like to see ur Prof n'Engl !!
Oops. The TAT tear me apart for that sorta thing...your Profile in English....
Quote:- In reduced light levels, does the voltage or current from a solar panel get reduced? ...
...'v'course, Tai. However, some if not many outfits sell it w/batt
Quote:- Can you suggest a suitable pump and panels?
No but watch the Sunday fliers like Harbor Freight; then there's Amazon, etc etc etc etc
Quote:- Maybe a battery charging mechanism to store extra charge in better light conditions?
The 'mechanism' apparently oft comes with the panel; though I'm not sure any such is needed. Probly direct conn 'tween
Quote:- Recommendations for connecting it all up?
I'm sure it's easy. Incidentally we have a coupla such ponds w/ falls, we love 'em. Mom had wanted 'em though \I thought the idea as nuts. But now I love 'em too I have some electronics and soldering equipment and skills.
Quote:If it makes any difference, the pond gets frogs in it, so nothing that'll harm them please.
No sweat. In one we have turtles and in the other, fish
Quote:Is it possible in a budget of, say, £50?
Well,...ours were $900 each [a bargain by the way], and while not entirely solar since our station serves the whole shebang. However, a 100-w panel(s) is about $150
I'll fwd this to my BH---oops, Better Half....Oops, mate, wife....who will corroborate my ob servations
...with battery...direct connection between, since the panel puts out a dc current while the batt is also charged by dc current, nd the voltage is probably plenty high
