I'm thinking of putting a small water feature in my garden. The problem I
have is that I live in a mid-terrace house and there is a small communal
pathway, about 1m wide, between my house and the garden. I cannot dig up the
pathway to run electric cables to the water feature.

I've noticed a few solar-powered water features which may help solve my
problem. Has anyone bought one of these? How do they perform? How powerful
are they? What happens when its cloudy/dark?

I bought new one last year off of EBay for around £50 to provide a fountain. It
did work during July/August 11:00 until 14:00, if you tracked it at the sun,
and if the sun was very strong, but any hint of a cloud and it would stop.

The panel was around 12" x 9" for comparison, so if my experience is usual I
would not bother.

They are generally hopelessly underpowered. The solar panel is the most expensive
part and is skimped in most commercial designs I have seen. Put a decent 3 sq ft
solar panel on it and it will perform OK.

The pumps also work well with a 12v lead acid accumulator or any other 12v DC 2A
supply.

The pumps are fine, but the solar panels are usually undersized.

Mine can throw water about 2m into the air at 8L / minute. YMMV
(that is with a decent power supply not with a wimpy toy solar panel)

Nothing - unless the system charges a battery.

How much do the pumps draw?

Guess: 50 mA which would require a 40 AH car battery to be charged
monthly. That's a power of 0.6W let's say 0.5W after losses.

According to http://www.onlineconversion.com/power.htm that's 0.368781
foot-lbs/sec. Sounds like enough for a small fountain.

My mother had one of the floating ones with a solar panel on top. I was
surprised to discover how well it worked on relatively cloudy days and
early in the year, but then she did have it against a white painted south-
facing wall, in Devon.

Personally I didn't care for the floating effect - prefer the bottom of a
fountain to stay still.

It didn't last all that long - died after a couple of seasons.

Depends how much you want to pump. The pump I had stalled on anything much
less than 8v and 1A.

Guess: 50 mA which would require a 40 AH car battery to be charged
monthly. That's a power of 0.6W let's say 0.5W after losses.

I ran mine at 14v 2A for about 10 minutes a day for greenhouse irrigation
from a big water butt.
Roughly 2 months between charging with a 20Ah lead acid accumulator
(I intended to use solar power but it simply wasn't cost effective)

Also you need a deep discharge battery - car batteries are really only
happy kept well charged for starting cars.

Take a look at these solar fountain : Solar Outdoor Fountains | DIY Solar water features | PowerBee Ltd This is an excellent company to deal with. I have now used them for some time and find their products well worth the money
