With reference to solar water pumps, consider the following statements:
1. Solar power can be used for running surface pumps and not for submersible pumps.
2. Solar power can be used for running centrifugal pumps and not the ones with piston.
Which of the statements given above is/are correct?
Explanation
Statement 1 is incorrect: Photovoltaic solar installations can power both surface pumps (open well/suction pumps) and deep borehole submersible pumps.
Statement 2 is incorrect: Solar-powered electrical setups are compatible with both dynamic centrifugal pumps and positive displacement piston/reciprocating/diaphragm pumps. Centrifugal pumps are commonly chosen for high-volume discharges at lower heads, whereas positive displacement piston pumps are used for high-head, low-flow deep borehole operations under low-solar irradiation.
Therefore, neither statement is correct — Option D.
