How much does it cost to install a solar borehole?
Given its economic benefits and incoherent power supply, a solar borehole is very important.
Solar Borehole Installation Cost
When you set up a solar borehole, you benefit from an unlimited water supply for your homes, farming, and other commercial uses for a long time.
In addition, this renewable green power can last over 20 years.
So, what are you waiting for? Join us in our conversation and discover how much it will cost you to build a solar faucet in Nigeria. You will also know the materials required to construct a solar water system.
In the interest of time, let’s look at the details.
Factors Influencing the Installation of Solar Water Systems
Certain factors determine the cost of constructing a solar water system in Nigeria.
Some of these factors include the cost of drilling, parts of green energy, the cost of labor, and a lot more.
Once these factors are identified, you may know how much you will spend executing a solar water system.
What it Cost to Drill a Borehole in Nigeria
The price of drilling in Nigeria depends upon the location. It isn’t easy to drill a borehole in some areas because of their topography, while it is easier in some geographical locations.
Nevertheless, the average drilling price in Nigeria is in the range of ₦300-₦600.
The price may be higher than this amount in a situation of difficulty.
Equipment Needed in a Solar Water System Installation
Here is some equipment involved in building a solar borehole with the prices of each item in Nigeria. Prices vary from region to region, but this is an average installation cost nationwide.
Structure for Solar Panels and Tank
Building a beam structure is very important to both solar panels and tanks. The girder structures are generally the best for this project. They’re made up of metal.
You can also build a tower for your reservoir and place the solar panels on the house roof, as most people in the country, to save cost.
The construction of a metal girder depends on the size and quality of the materials used. But it will cost you approximately ₦300,000 or more to do the work.
Solar Panel Price List
A solar system can’t be complete without a panel.
This panel is responsible for generating solar power in the form of DC. An inverter is then used to convert DC to AC, which is needed to power the submersible pump, which supplies water to the tank.
When you induce an array of panels, it will increase the energy capacity, which is crucial in solar borehole construction.
Various types of solar panels are commercially available. We have monocrystalline, thin-layer, polycrystalline solar panels. Each of these panels has its pros and cons.
So, the prices of solar panels also depend on their type.
Monocrystalline Solar Panel
It is the most powerful solar panel relative to other types and the best for constructing solar water systems. Thus, obtaining this panel brand will cost a lot due to its high efficiency.
Buying a monocrystalline panel will cost about ₦20,000 – ₦80,000, depending on the panel’s power.
100 W – 300 W of monocrystalline solar panels are available in Nigeria.
Polycrystalline Solar Panel
It is not expensive to purchase this kind of solar panel because it is low efficiency. In that respect, getting that type of panel in Nigeria will cost about ₦18,000 to ₦54,000.
The panel power varies between 100 W and 270 W.
Thin-film Solar Panel
This panel also has low efficiency but is very portable and flexible.
Therefore, the price of this panel is also low, like polycrystalline. It costs around ₦18,000 to ₦48,000 to buy this panel across Nigeria.
Cost of Water Pump
Pumping machines are responsible for extracting water from the well into the reservoir. Therefore, for a solar drilling installation, two pumping machines are used.
We’ve got the submersible pumps, the surface pump. So the price depends on both kinds of pumping machinery.
Submersible Pumping System
This type of water pump is submerged into the ground below a depth of 10 meters. It can pump water from a depth of approximately 700 meters.
Thus, the cost of obtaining an excellent submersible pumping machine is around ₦30,000 – ₦100,000 and above, although these prices depend on the machine’s capacity and the brand.
Surface Pumping System
By the name, you can see it is placed on the earth’s surface. This pump can draw water from 100 to 200 feet deep and beyond.
So, the cost of purchasing a surface water pump is around ₦20,000 or more. The price is also dependent upon the power of the machine.
Other pumping machines include the circulating pump, boost pump, sump pump, adjusted floating pump, etc.
Pump Engine Controller
It is essential to control how a pumping machine operates. This is why an automatic control is produced to switch off the water pump once it reaches the definite program.
Here, you can be sure that your water pump is safe.
The cost of acquiring a controller is about ₦10,000 – 150,000 or even more than that. This amount is subject to the capacity of the controller.
As we mentioned above, the solar panel generates power in the form of direct current, so an inverter converts it to alternating current.
You can run your solar pumping machine without needing a UPS, but this will cost you a lot. This is because direct current pumps are more expensive than alternating existing pumps.
So, to obtain an inverter, it will cost you about 50,000 or more. Inverters are running for ₦350,000. These prices are dependent upon the KVA capacity of each inverter.
These solar batteries mainly store the charged electricity from the panels during the day. You may not need batteries for a solar water system.
As stated above, the water pump can work directly from the solar panels. It’s only needed when you want to pump water at night.
Thus, an excellent solar battery costs approximately ₦50,000 – 145,000 or more, depending on the AH. Please note that the more batteries you have, the higher the energy it retains.
So, it’s the breakdown of the expenditures you see when setting up a well-functioning solar water system. A good thing about a solar water system is that the cost of servicing is meager.
So, if you can set up one, you’ll enjoy unlimited water in your homes, businesses, and elsewhere.
