Solar Water Pumps

Solar water pumps use solar force as an attractive option to bring water to remote homes, cabins or campgrounds. Some people have employed solar drip irrigation and pumping for gardens and homes. This technology has been around for decades, is efficient, and there are a number of government programs and utility incentives to use it.

Solar water pumps do not require putting complicated connections to the utility grid. This is just another way to enjoy the benefits of solar power. Gas and diesel are vastly more expensive, which in turn, causes the price of electricity to increase as well. Solar energy is becoming a hot topic with oil being a non-renewable source of energy.

Solar pumps fall into two major categories - surface, which includes pressure, delivery, and booster pumps & submersible which is primarily submersible well pumps.Delivery pumps are used to move water from one place to another. Some are capable of high pressure while others are intended mainly for moving large volumes at low pressure (such as moving water from a cistern to a stock watering tank). Flows can be small (1/2 gallon per minute or so) up to 30-40 gpm. Some (such as the popular 12 volt Shurflo pumps) are often used for pressurizing water systems in homes, RV's, and boats.

Solar water pumps and dc pumps are currently being used to irrigate crops, water livestock, and provide potable drinking water. A solar water pump uses peak solar array output which frequently coincides with high water demand during long, dry summer days. In the event of cloudy weather solar powered pump systems often use storage tanks to store excess water.

Solar water pumps are cheap to build and cheap to power. And after the initial cost, there no one else to pay. Even uncle Sam says it good for your taxes.

Solar energy is the way of the future. Many pond owners are switching from electric pumps to solar powered pond pumps, mainly because they cost nothing to operate. However, these pumps also serve a second purpose -- solar water pumps are environmentally friendly!

Solar water pumps brought a lot of attention to themselves once again with the recent variations in prices of oil that hit almost everyone. A similar thing happened in the late 70s but we did not learn the lesson. As soon as oil prices came down, so did our intent to use more sustainable energy sources.

Active systems can further be divided into direct and indirect systems. Direct systems directly heat the water in the collectors while an indirect system heats a different fluid (e.g. freon or distilled water) and the heat from this fluid is then transferred to the household water.
