Solar Water Pump Systems
What it is
For people living in remote areas, solar water pumps are usually the only solution as there is no access to diesel. If there is diesel, Solar Water Pumps are the only solution or an excellent alternative for diesel as the cost of running power lines or diesel pumping may be too great.
A solar powered water pump differs from a regular water pump only in that it uses the sun's energy to supply electricity for the pump. The solar panels absorb the sun's energy and convert it to electrical energy for the pump to operate. All the pumped water is stored in a water tank so that there is constant supply even in bad weather conditions and during night time where there is insufficient power to generate the solar water pumps. Solar powered water pumps represent a higher initial investment, however, over a period of 5 years they represent a cost benefit due to minimal maintenance costs compared to AC pumps run with a generator.
How it works
A Solar Water Pump System comprises several PV (photovoltaic) panels that produce direct current (DC) electricity when exposed to sunlight. The DC current is collected by the wiring in the panel. The current is used to supply a DC pump, which pumps water whenever the sun shines, or the current is stored in batteries (for a battery-coupled pumping system) for later use by the pump.
