SOLAR PUMPS

Most farms and rural hotels have no access to city water and rely on tank water or water from a dam or stream. Very often people in these situations the use of the dam or stream water for their gardens and water collection tank on the roof for home use. Both applications are ideal for a solar pump in the supply of free water courtesy of the sun.
The great advantage of a solar water pump for windmills is that when water is most needed in the summer days are longer, with more sunlight, while the wind mills wind blow at the time necessarily .

For domestic applications of solar diaphragm pump is ideal because it can supply up to 34 liters per minute with automatic cutoff switch that cuts to 40 PSI. It is also advisable to fit an air tank to the solar pump to avoid the annoying sound all night cutting pump and if there is a small leak in the system.
The compressed air tank delays in air pressure drop and prevents leaking solar pump on and off as often. Even for big houses 90 watt panels solar only two are required to keep the battery charged to supply water for at least 4 hours per day, which is more than enough.

Garden applications is common to use a submersible pump solar water of the dam or river or perforated.
The ideal situation is to pump water with solar pumps in a tank on a stand or a hill above the house and gravity feed for the garden. In these situations do not require batteries with solar panels are connected directly to the solar water pump through an inverter that converts direct current into alternating current phase.
Flow up to 150L / M and the heads of 100 feet, more are possible with solar pumps.
