It may be true that electricity is not the basic necessity of life but its deprivation can cause us difficulties in accessing the basic necessities of life. Where there are no power lines life becomes quite difficult to spend, but now thanks to the sun we can now take benefit of solar energy.

Solar pumps are a clean and very simple alternative to fuel-burning generators and of course windmills. Solar pump has the ability to produce more water as compared to a windmill or generator even in the harsh climate. Solar pumps are basically designed in such a way that they utilize DC power supply from the panels consisting of photovoltaic cells. Solar pumps can also be modified to operate on AC power supply.

Solar Pumps

Solar Pumps

Solar water pumps are designed in such a way that they only use DC electric supply from a panel consisting of photovoltaic cells. They must operate at low power during the low light conditions. They must not be stalled or over heated.

Low pumps utilize low volumetric mechanisms due to which the water is sealed in the cavities and forced upward. Where there is a need for high volumes of water then centrifugal pumps are used.

Surface pumps are mounted on the ground level, whereas submersible pumps are lowered into water. Submersible pumps are quite common in deep water wells.

Pump Controller

Pump controller is also known as the current booster. It is an electronic device utilized by most of the solar pumps. It works like an automatic transmission device.

It helps the pump to start and preventing it stalling in case of weak sunlight.

Solar Tracker

Solar pumps are also fitted with solar trackers. Solar trackers adjust the PV array according to the position of the sun, thereby increasing the energy gain up to 55%.Where there is availability of more peak sun hours then overall cost can be reduced by employing a smaller pump and a smaller power supply.

Tracking is efficient most when the weather is clear and sunny, at the same time it is less effective as the weather turns cloudy and cold.

Storage

The most important part is that of storage. Storage depends upon the climate and the usage of water. It may be possible that only three to four days storage may be required. For the sake of simplicity and economy some systems use water storage rather than batteries. A float switch is fitted in the pump which turns the pump off when the water tank is filled, so as to prevent the overflow and wasting of water.

Advantages Of Solar Pumps

Comparison of a solar pump and a windmill is quite meaning less as the solar pumps are quite easy to install and maintain as compared to the windmill and also they are less expensive.

Livestock Watering

Solar pumps are used for watering the livestock. Cattle ranchers enthusiastically use solar pumps. Read the full story
