How Do You Compare Solar Water Pumps?
Solar pumps are popular because they are affordable and allow water to be accessed where there isn’t access to electricity. A common application in the United States is supplying water to livestock in remote pastures. They use solar panels that absorb sunlight and convert it to energy. The panel you choose will depend upon the pump you’ve selected, but 75 watt panels are most commonly used for a pump application and are capable of pumping 75 gallons of water per hour. Determine how much water you need to pump. According to Oasis Montana Inc., one person requires about 75 gallons of water a day for eating, drinking and bathing. One hundred head of cattle consume in the range of 2,000 gallons per day. Look at the distance you will need to pump the water–for instance, how far the source is from the application and how deep beneath the ground your source lies. This is known as the total dynamic head and is measured in either feet or meters, or in psi, according to Oasis Montana. Most well
