ABSTRACT
In areas of developing countries with no access to grid power, diesel-driven pumps are commonly used for irrigation in farming and forestry. Diesel pumps, however, require regular maintenance and refuelling, and they place a burden on the environment. Wherever the failure of a diesel pump and the expense of its operation constitute an economic risk for the operators of small-scale irrigation systems, photovoltaic pumps (PVP) represent a reliable, alternative means of water delivery.
