As the header, are they usefully? I am building a small wildlife pool,
and would quite like to have a smaller pool above, pump water from the
lower to higher one and let it "stream" back. I am living in the North
Midlands of the UK, so sunshine is not constant. I realise that the
"stream" would not be constant, but would the system work?

Here's a solar fountain.
"Low-voltage, floating fountain is a safe, easy way to add some "life" to
your backyard pond! Pump and filter are both included, as are three
interchangeable, variable fountain heads that send a spray up to 24" high.
Only operates when sunlight directly hits the German-engineered solar panel,
but it can be tethered to make sure it doesn't float into shadow areas of
your pond. Pumps up to 40 gals. per hour. 12" in diameter, 2-¾" thick."

That's a whopping 1.76 fluid ounces per second in direct strong sunlight.
Hardly a trickle in other words. I can dribble faster.
