The solar pump is a system that runs on electricity produced by photovoltaic panels for pumping water. It is an ideal alternative option for replacing conventional generators that function by utilizing energy from fossil fuels for pumping water. Solar pumps generate electricity from sunlight.
Solar water pump converts solar energy into electricity for running the pumping system, hence replacing the erratic grid supply and diesel-powered system. It is powered by solar modules that support drawing groundwater for irrigation.
Usually, remote places rely on diesel engines and manpower for water supply. As solar pumps replace conventional pumps by offering numerous benefits such as weather-relevant, and socioeconomic, therefore, these pumps are massively utilized for irrigation and water shock application.
Solar pumps are easy to install, robust, and require minimal maintenance. The lifespan of solar pumps is around 20 years. Solar pumps are widely used in areas with electricity problems.
Working Mechanism of Solar Pumps:
PV panels experience sun rays by solar energy, these rays are further converted into electrical energy with the support of Si wafers located within the PV panels. The electrical motor pumps system operations through cables by utilizing the solar energy. The pump picks up the soil water and supplies it to the fields by shaft revolution.
Submersible Solar Pumps
Submersible solar pumps have the potential to lift water up to 650 ft and can be easily installed in a big well. When water depth reaches 20 ft above the earth's surface, then the batteries and solar panels are turned off. In several cases, it sources to power. Usually, water is pumped throughout the day, as the sun shines, and water is stored in the tank for usage. It is suggested to store water in good weather conditions, as it will not pump water in bad weather.
Surface Solar Pumps
Surface solar pumps are utilized in shallow wells, storage tanks, and ponds. If water depth reaches 20 ft or less from the surface, pumps cannot pick the water high from the well. These pumps can push the water to a distance of 200 feet or more. These pumps are ideal for pumping or lifting water from a high depth of 20 meters.
Floating Solar Pumps
Floating solar pumps provide convenient solar pumping from surface water resources or water troughs. There are varying applications for these pumps such as livestock watering, micro-irrigation, drainage, and aeration.
Rising agricultural application of solar pumps leads to their increasing demand, which, in turn, drives the solar pump industry revenue. It is due to the rising adoption of renewable energy sources, and to decline in the consumption of fossil fuels for irrigation in agriculturally based economies, such as China, India, and a few in Africa.
