Water pumping has a long history with solar power; so many methods have been developed to pump water with a minimum of effort and encorporate solar energy. These have utilized a variety of power sources, namely solar for energy power generation.Solar irrigation pump systems are used principally for three applications:
• Muncipal drinking water supply schemes
• Livestock drinking water supply schemes
• Farming/Irrigation water supply schemes
A solar irrigation pump system methods needs to take account of the fact that demand for irrigation system water will vary throughout the year. Peak demand during the irrigation system seasons is often more than twice the average demand. This means that solar pumps for irrigation are under-utilized for most of the year. Attention should be paid to the system of irrigation water distribution and application to the crops. The irrigation pump system should minimize water losses, without imposing significant additional head on the irrigation pumping system and be of low cost.
