Utilizing solar energy is environmentally friendly. Although the initial cost of installing solar panels is expensive, it comes out cheaper in the long run with the money you save on electrical bills. Plus, solar pumps are safer because without electricity chances of electrocution are nil.

But it is not suitable in gloomy countries. The sun should always be shining in order to store enough energy to power the fountain. Although there are back-up batteries where energy is stored, if the sun doesn't shine for a week, the energy is used up.
