There are two primary reasons for having a pressure tank in a pumped water system -- to give the pump motor time to dissipate the extra heat energy generated each time the pump starts, and to store water under pressure so the pump does not have to come on every time there is a small, intermittent demand for water.
Photovoltaic (PV) panels produce electricity from sunlight using silicon cells, with no moving parts. They have been mass-produced since 1979. They are so reliable that most manufacturers offer a 25-year warranty. They work well in cold or hot weather. Solar water pumps are specially designed to utilize DC electric power from photovoltaic panels.
