A solar powered pump is a great alternative to a electric or diesel powered pump. They are not only more economical to run, but they also have far less impact on the environment. They can also be used in places where electricity is otherwise unavailable and where wind power is not suitable/does not produce enough energy. Solar water pumps come in range of sizes and can be used for anything from a small outdoor aquarium or swimming pool through to pumping water from a bore providing for a domestic water supply, irrigation or livestock.

There are also some disadvantages over more traditional forms of pumps. The main disadvantage is the higher initial outlay cost of a solar pump. This can be offset somewhat by the solar rebates as well as the long term savings, but the higher initial cost remains a concern for some people. Solar power also requires enough sunlight to power the pump. This means that solar power may not be suitable in applications where sunlight is restricted, such as under the shade of a tree, or where your pump needs to run during hours of darkness. This can be managed by using a hybrid solar/electric or solar/petrol system.
