Very happy so far with this product. We bought it to replace an electric water feature pump and were concerned whether it would be able to lift the water up around 60 cm from the pump reservoir, but we need not have worried. It is very powerful and could easily do twice that. The pump is a decent size and by attaching one of the supplied pipe connecters it was easy to push it into the existing water feature hose without any problem. The power cables are very long so in effect you could have the solar panels 6 metres from the water feature if sighting them in a sunny spot is difficult . The only slight niggle is the cable that links the two solar panels is only around 50 cm so you're limited to the distance you can separate them. That said you could swop the cable from the main solar panel to the battery/controller and have them 2 metres apart but that would mean that the nearest panel would have to be 50 cm from the battery/controller, anyway there's are ways you could jiggle it. We tried the system with only one panel, as there is another version of the exact same system that is the same available on Amazon for around £90 (Bermuda Mars Solar pump ) 880 litres and hour that only uses one solar panel. Bermuda Mars Solar Pump We tried ours with one panel and found that it works fine and charges the battery at the same time but only worked really well in direct strong sunlight, adding the second solar panel again created a flow when there was bright white cloud also with no direct sunlight. Be warned it won't work in grey cloud but that's where you use the battery. Worth mentioning is that the battery back up doesn't cut in automatically , when the solar stops, you'll have to push a button on the controller, the good thing is though if you choose to use the battery when it is on an off cloudy it will also trickle charge the battery at the same time. Note you can only alter the flow volume when it is working in battery mode. We haven't tried the lights so can't comment on them. The solar panels are very well made and really create a good voltage as soon as the sun hits them. The only negative is the ground stake doesn't actually have a permanent fixing to them , it's a case of a slot in the top of plastic stake that the frame just pushes into (props it up) if you want to fix the panels to something else other than in the ground you'll have to think of finding an alternative method. The controller is quite heavy but very well made and should stand up to all weathers the lead acid battery can be replaced when it's had its day by unscrewing the controller cover and they can be purchased for around £18. All in all a very well made and powerful system which will give you a really good fountain spray or an economical environmentally friendly replacement for your electrically operated water feature , which will hopefully pay for the purchase price after a few years! ... Just an update 3 years later and still going strong! Just had to replace the lead acid battery which had finally run out of puff which is just a matter of unscrewing 5 small screw on the front of the control unit and pushing on the spade connectors. I obtained this from Amazon for £12.99 https://www.amazon.co.uk/gp/product/B008PDLGZ2/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1. Works better than the original battery and feeds our water pump feature very well (see pic). The only maintenance required is to clean the pump filter regularly.Still very happy with the performance.
