This solar pump is good finish, especially in the solar panel. The connection between the pump and the board is long enough to make a lot of difference between the pump and the panel, which can be useful in cases of pelvic position in shaded area. Note also that the pump connector of the cable is plugging in the solar panel is sealed with a screw cap, which is well seen. Several tips on the pump, which seems consistent with the announced theoretical throughput, which remains modest. Now for the performance itself. The good surprise is that operation is sunny, the pump snaps without problems in sunny situation. Besides, in my part of a Britain in late April, I note that the pump also snaps even in situations of sailing high, which is better than what I thought. By cons, forget operation under cloudy or overcast skies, it does not operate. At the same time, we must consider that this pump can be useful to oxygenate a pond when temperatures rise, ie generally sunshine situation. So, that's the job. In terms of disappointments, the batteries in my case are useless. Impossible when I place in charge mode or in hybrid mode (direct operation + load in parallel) to demonstrate that the pump operates on battery when the sun disappears. Instead, the batteries seem useless. This may be a problem with my copy, but suddenly, it is expensive pump if the battery does not work properly. In total, this pump acts as I expected, ie start without assistance when the sun arrives. But note also that the water in my pond is clear, and that in two weeks I did not have to clean the pump filter. In water loaded with sediment, it could be more problematic level maintenance.
