Solar Water Pumping Kit

Information about direct solar water pumping kits

The direct solar water pumping kits or solar pump kit have become an economical and ecological solution for many farmers and individuals living in isolated areas. For this, the direct solar water pumping kits offer features that are hardly comparable to other pumping systems competing with the direct solar water pumping kits.

 

These direct solar water pumping kits allow you to pump water from either a well to a container or direct irrigation with much higher technology and lower operating costs thanks to experience in years of development. In addition to this, our brand specialized in direct solar water pumping kit has made a great effort to get the most resistant and reliable materials for these direct solar water pumping kits. Currently our solar water pumps that work directly with photovoltaic energy (are powered by direct current) and are capable of pumping water from the surface or from wells of good depth.

 

How does direct solar pumping work?

The operation of the pump is totally variable depending on the power supplied by the capture of the photovoltaic panels. The operating curve of the pumps is normal operation, that is, working 100%. Operating hours working at 100% depends on peak solar hours.

Estimating the peak sun hours with constant solar irradiation of 1000W / m2 we can know the hours of operation of the pump at its nominal power.

In short, the direct solar pumping systems work without batteries, so their operation will occur whenever there is solar radiation. That is, the system is activated when solar panels receive photovoltaic energy early in the day, offers maximum performance in the central hours of the day and reduces their productivity as the night approaches in the absence of sufficient photovoltaic energy to the activation of the pumping system. It is an installation with rapid amortization and highly recommended whenever it is expected that its operation is at daylight hours regardless of inactivity during the night.

We have the possibility to easily consult on the internet at http://re.jrc.ec.europa.eu/pvgis/ peak sun hours depending on the geographical area, in this way we will ensure the operating hours of the direct solar pumping system. Depending on the location, the following peak solar hours are usually estimated:

• Winter: 3.5 hours of peak sun.

• Summer: 7 hours of peak sun.

For more information on the operation or dimension of your direct solar pumping system, contact us and our technical team without obligation will advise you on this.

 

Installation of direct solar pumping kit

When installing any solar pumping kit, solar pumping kit for wells or direct solar pumping kit, the possibility of placing a water accumulation tank in height must be taken into account, in this way the water can be distributed by gravity and there is no need to install a second pump to pressure irrigation or complicate the solar system too much by adding more power. If, on the contrary, this possibility does not exist, or it is necessary to pump water 24 hours a day, you can contemplate the installation of batteries together with the solar pumping kit or complement the direct solar pumping with the power of the electricity grid or from a generator.

 

Types of Direct Solar Water Pumps

Currently for any solar pump kit, there are several ways to run a water pump through solar photovoltaic panels with solar pumping or solar pumping kit for wells, our solar pumping kits or solar submersible solar pump kit. In addition, to ensure satisfactory operation of the solar pump PlusEnergy recommends installing 1.5 times the nominal power of the pump in solar power. Broadly speaking, the types of direct solar pumping that PlusEnergy offers are the following:

The submersible solar pump kit or solar well pump kit significantly reduces the amount of panels to be installed since the pump works at a voltage very close to that of the panels and there is no need for inverters or other electrical components to operate the system. Usually a solar pumping kit has a solar controller that is responsible for maximizing the performance of the solar panel and ensuring a stable and constant voltage to power the pump. There are continuous pumps from lower to higher power.

 

Where to use the direct solar water pumping kits

The direct solar water pumping kits for solar pumping are a very practical solution when drinking water or irrigation is needed in isolated places, when water is needed to supply livestock, etc.

The kits pumping direct solar water of small size can be done through water pumps that operate in direct current, so we do not need to transform the current to three-phase to be able to supply the water pump. For water pumping kits, solar pump kit or small direct solar pumping kit, there are submersible and surface pumps, all cases can be useful.

 

Components of direct solar water pumping kits

In the direct solar water pumping kits there are four main elements:

• Solar panels, depending on the power that the solar pump kit needs to have and the amount of water it needs to extract.

• A solar pump controller, a device responsible for getting the most out of the solar panels of the solar pumping system, also regulates the operation of the water pump.

• The submersible water pump.

• Probes for both tank and well.

 

What pump model do I need for my direct solar pumping system?

The correct sizing of the direct solar pumping system depends on the needs of each installation. It is essential to know the calculations and know how to read the information and tables of the manufacturer of each direct solar pumping system for the correct choice of the pump.

 

Data needed to size a direct solar pumping system.

Knowing the flow of the direct solar pumping system is important for the correct sizing and it is the demand for the necessary water, that is to say the necessary liters / hour of discharge. The pump is what sets the amount of fluid that can be transported. The unit of measure of the flow is m3.

The manometric height of the direct solar pumping system is another of the essential variables for the correct choice of the water pump, and it is the maximum discharge height, taking into account water depth, travel water travel distances, necessary pressure and losses in pipe. The unit of measure is meters of manometric height expressed in (mca). Within this variable we differentiate:

• The discharge height of the direct solar pumping system, that is, the vertical and horizontal distance between the pump and the discharge end point.

• The suction height of the direct solar pumping system which is the vertical distance between the place where the water is located and the distance of the pump installation. This value should not be taken into account in submersible pumps.

• The pressure of the direct solar pumping system is another variable to take into account and is the force that acts on the fluid. It is estimated 10 mca for each pressure bar.

• And finally the pressure losses of the direct solar pumping system are pressure losses in the fluid related to small leaks, elbows, pipe roughness. We usually standardize losses at 10 mca at the manometric height to avoid losing impulse at the end point.

 

Calculation of the manometric height of the direct solar pumping system

The following example is presented: we have a well 30 meters deep, the maximum height from the well to the tank is 20 meters and we need 1 bar of pressure. We always estimate 10 mca of load losses. As it is a submersible pump system, we will not take the suction height into account. We perform a simple calculation to estimate the manometric height:

Gauge Height = Drive Height + Pressure + Losses + Suction Height =

Gauge Height = (30 + 20) + (10) + (10) + (0) = 70m.ca

Flow estimate

It is very important to estimate the necessary flow, it depends on the type of consumption of the pumping system that we are going to carry out, that is, irrigation, supply for livestock or for domestic use. Following the example, we estimate a demand of 3.5m3 per hour, that is to say around 3500 liters / hour.
