When electricity is required at a location that is not supplied by the grid, or where it would be costly to electrify, the relatively high cost of the energy can be justified, for example the pumping of water for irrigation of commercial crops: In a very large percentage of such applications, the location is completely isolated from any form of energy source, so that solar energy is one of the few alternatives available.

The extremely high cost of electrifying cannot be justified under any circumstances, however the modest investment in a small solar installation and pump can be amortised by the increased yield from the land due to the irrigation.

expert solar can carry out a feasibility study to ascertain whether a solar system is viable for any situation.
