Project Description

  • reliable water supply
  • flow rate up to 18m3 / h
  • aplication in fruit growing, vegetable growing, viticulture
  • at no additional cost of exploitation
  • possibility to work even through aggregates in the absence of solar energy
  • quiet and reliable operation
  • easy to operate system
  • motor overheating protection pump protection from water shortage in the well

The system is based on harnessing solar energy for irrigation purposes.

It is especially suitable for use in fruit growing, viticulture and vegetable gardening when drip irrigation.

The basis of the system is a well pump that connects directly to the solar panels without installing additional batteries.

In the absence of solar energy, in cloudy or rainy weather if there is a need for water, the pump can also run on electricity, either through an existing electrical installation or through an aggregate.

The advantage of this system is that it has no additional operating costs, ie. solar energy is free of charge, unlike electricity generated from either the existing grid or through aggregates (gasoline or diesel).

Another advantage of such a system is the completely silent operation, unlike systems powered by aggregates.

Operating the system is extremely simple.

It is enough to start the system by turning the switch and it still works on its own. If the weather is cloudy, the system will give the amount of water that can be obtained depending on the number of solar panels installed. If there is not enough solar energy, the system will automatically stop and restart when conditions are met.

In case of lack of water in the well, the pump also stops and starts running only when the water returns.

The pumps can be divided into two basic types:

  • pumps with great depths delivering less water (up to 1.0 m3 / h and 250 m deep).
  • pumps that deliver a large amount of water from shallow depths (can deliver up to 18 m3 / h with 2 m depth).

Installation of the solar panels to power the pump can be either on a fixed carrier, or on a carrier with two pivoting axes that monitors the trajectory of the sun at all times. This results in up to 50% more utilization than the fixed-carrier system. For this system, it is recommended that six to eight solar panels be mounted on a pivot-mounted carrier.

For large areas to be irrigated, we recommend a system with a large number of panels, a classic well pump (3×380 VAC), and a frequency regulator powered by solar panels.

Large areas can be divided into valves into several parts, so that the system automatically switches from one part to another when it supplies the required amount of water. It also enables remote monitoring and control of the system via a mobile phone, by sending a text message.
