Does the water pressure ever drop or suffer when using a water solar pump?
Yes. Typically households use conventional AC powered water systems which pump from a well or other water sources, into a pressure tank that stores water and stabilizes the pressure for household use. However, this will not work with pumps operating directly from PV modules because the sun may not be shining when you need pressure and thus the pump may not keep up with household use. There are two ways to solve this problem. A non-pressurized water tank can be located high enough above the house for gravity to supply the water pressure. This can be on a hill or a tower. The second solution is to have a battery operated pressure booster pump which can fill a pressure tank as needed from a storage tank that is filled by a solar pump during the day.
