Is anybody running a water feature off a solar-powered pump? If so could you give me some idea of where to buy the pump and solar panel (Pattaya/Rayong for preference), and approximate costs? I'm not planning anything huge, just want to get the water trickling round pleasantly.

Good idea and have a battery in with it so you can run it at night.

Don't know if it's a national firm or not, but AMORN in Chiang Mai is good for solar panels. They also have those tacky garden solar lights, and possibly solar fountains, but the panels are defo the real deal. Amorn is like an odds n sods store that mainly deals in electronic components, test meters, etc. I'd also look to Global House.
