A revolution is taking place in how water is being pumped in remote locations beyond the reach of electric power lines. Solar-electric, or Photovoltaic, power has proven to be an ideal way to lift water for drinking, sanitation, stock tanks, and irrigation. Photovoltaic pumps have been on the market since 1980 and are in use all over the world.
It has been known for many years that some substances give off electrons when light strikes them and these electrons may be used to form a current. The development of photovoltaic (PV) technology began in 1955 and came of age in the 1980’s. PV technology was initially regarded as “space age” because the use was limited to satellites, but in 1980 the cost was reduced by two-thirds making PV modules more affordable to the general public. PV technology is built on the solar cell. This small, paper-thin disc is made of silicon, an inert crystalline material refined from sand. Exposing the solar cell to sunlight causes electrons to jump from the positive to the negative side of the cell. Thus generating direct current. Solar cells are assembled into panels called modules. A solar panel will produce about 50 watts of power.
Photovoltaic (PV) panels are the simplist possible way to generate electricity beyond the reach of power lines. They have no moving parts and last for decades with virtually no maintenance. Solar power is no longer an expensive, experimental energy source. Photovoltaics are now standard in many commercial, industrial, military, and consumer applications—wherever modest amounts of power are needed beyond the power lines.
Solar-powered Water Systems are practical in flat terrain where the sun shines.
Solar-powered water pumps can be placed in or next to the pond or other source of water and the water can be pumped where it is needed.
Solar electric water pumping cuts down on waste because its based on natural cycles. Your panels give the most pumping power on the sunniest days—when you need the most water.
Solar power is clean. You never have to worry about polluting the groundwater or air with a gas-powered pump.
Solar-powered water systems take very little maintenance because they only have a few moving parts. They have long life—usually 20 to 40 years. And solar water systems never run out of fuel as long as the sun is shining.
