PHOTOVOLTAIC SOLAR PUMP ADAPTABILITY IN THE AGRICULTURAL SECTOR

Fotovoltaic energy as an alternative source, usually appears against grid connected systems. However solar pumps could service in irrigated rural areas too, where hard to find grid plugs, thus farmers have to use gas or diesel powered pumps which is more expensive than grid energy.Use of solar pumps in sunny coutryes is increasing. This areas could use the pumps all the year, hence they could achieve 2 year payback. for example: USA – California, Chile, African States, India. In Hungary we could use solar pumps only half of the year, but its payback time could be thought-provoking. Int he view of environment the apply of the solar pumps could decrease the harmful emissions. In this article we have calculated payback times under various conditios. As well as the yearly solar panel work for the year 2010.
