What wattage does the solar photovoltaic panel produce?
5 watts maxmimum, usually less, is the PV’s output. The solar pump’s peak output is approx 0.7 litres a minute peak. Again it it usually less than this except in full perpendicular sun. Back to the top FAQ: I am slightly concerned about the head available from the solar PV pump. Do you have engineering data that I could use to determine whether I’m likely to have a problem with the length and type of pipe I might use for my solar panels installation? A: Please don’t be concerned. The photovoltaic solar pump is actually too beefy for the job. This is a deliberate part of our design as a way of getting a very long life from it. Not only has it a long life brushless DC motor but the solar pump head itself has been dramatically de-rated by fitting an internal pressure bypass which opens at about 1 bar if any pipe is frozen. Without this, the solar pump could deliver about 5 bar, which is way beyong th emaximum pressure allowed for the panel. Hydraulically, this pressure limitation is fine
