Solar Pump

About Solar Water Pumping System

A Solar Pump is running on electricity generated by solar panels. Today, all pumps are working on grid electricity or diesel run water pumps. The operation of solar powered pumps is more economical mainly due to the lower operation and maintenance costs and has a less environmental impact than pumps powered by an IC engine. Solar pumps are useful where grid electricity is unavailable and alternative sources (in particular wind) do not provide sufficient energy

Solar powered water pumps can deliver drinking water for livestock or irrigation purposes. Solar water pumps may be especially useful in small-scale or community-based irrigation, as large-scale irrigation requires large volumes of water that in turn require a large solar PV array. Solar PV water pumping systems are used for irrigation and drinking water in India. The majority of the pumps are fitted with a 2000 watt - 3,700-watt motor that receives energy from a 4,800 Wp PV array. The 5hp systems can deliver about 128,000 litres of water/day from a total of 50 meters setoff head and 70 meters dynamic head.

The cost of only solar panels is 80% of the total project cost. The size of the PV-system is directly dependent on the size of the pump, the amount of water that is required (m³/d) and the solar irradiance available. Due to expensive prices of solar powered pumps, the market for solar pumps especially in developing countries such as India and Africa are highly dependent on government funding. “The Government of India has been taking strong steps towards solar pumps popularization since the past few years

A photovoltaic solar powered pump system has three parts:

1 . Solar Panel

Solar panel uses sunlight as their source of energy to generate light. A PV module is a single unit which is assembled and connected in 60 cells or 72 cells. Solar PV array absorbs sunlight and generates electricity for the residential and commercial application. Each and every solar panel is rated with its output power (Denoted as DC Power) and it ranges from 40 watts to 350 watts in 60 or 72 cells.

2 . The Controller:

The purpose of the controller is twofold. Firstly, it matches the output power that the pump receives with the input power available from the solar panels. Secondly, a controller usually provides a low voltage protection, whereby the system is switched off if the voltage is too low or too high for the operating voltage range of the pump. This increases the lifetime of the pump thus reducing the need for maintenance.

3 . The Pump:

The voltage of the solar pump motors can be AC (alternating current) or DC (direct current). Direct current motors are used for small to medium applications up to about 3 kW rating and are suitable for applications such as garden fountains, landscaping, drinking water for livestock, or small irrigation projects.
