How much does it cost to install a solar borehole?

A solar borehole is very important, given its economic benefits and incoherent power supply.

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 such a long period of 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 be aware of the materials required in the construction of a solar water system.

In the interest of time, let’s have a look at the details.

Factors Influencing the Installation of Solar Water System

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 have an idea of how much you will spend in the execution of a solar water system.

  • What it Cost to Drill a Borehole in Nigeria

The price of drilling in Nigeria depends upon the location. It is difficult to drill a borehole in some areas because of the nature 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 can vary from region to region, but this is an average installation cost across the country.

  • 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 basically made up of metal.

You can also decide to build a tower for your reservoir and alternatively place the solar panels on the house roof as most people do 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 the generation of solar power in the form of DC. An inverter is then used to converts DC to AC, which is needed to power the submersible pump, which in turn supplies water to the tank.

When you induce an array of panels, it will increase the energy capacity which is very crucial in solar borehole construction.

Various types of solar panels are commercially available. We have mono-crystalline, thin-layer, polycrystalline solar panels. Each of these panels has its own 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, it will cost a lot to obtain this brand of the panel due to its high efficiency.

To buy a monocrystalline panel, will cost about ₦20,000 – ₦80,000 depending on the power of the panel.

There are 100 W – 300 W of mono-crystalline solar panels available in Nigeria.

  • Polycrystalline Solar Panel

It is not expensive to purchase this kind of solar panel, simply because it has low efficiency. In that respect, it will cost about ₦18,000 to ₦54,000 to get that type of the panel in Nigeria.

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 inexpensive like polycrystalline. It cost 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 the depth of 10 meters. It has the ability to pump water from a depth of approximately 700 meters.

Thus the cost of obtaining a good submersible pumping machine is around ₦30,000 – ₦100,000 and above, although these prices depend on the capacity of the machine as well as the brand.

  • Surface Pumping System

By the name, you can see that its place on the surface of the earth. This water pump has the ability to draw water from 100 to 200 feet deep and beyond.

So the cost of purchasing a surface water pump is around ₦20,000 and 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, and so on.

  • Pump Engine Controller

It is very important to control how a pumping machine operates. This is the reason 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.

  • Solar Inverter

The solar panel generates power in the form of direct current as we mentioned above, so an inverter does the work of converting it to alternating current.

You can run your solar pumping machine without necessarily needing a UPS, but this will cost you a lot. This is because direct current pumps are more expensive than alternating current pumps.

So to obtain an inverter, it will cost you about₦ 50,000 and more. Actually, inverters are running for ₦350,000. These prices are dependent upon the KVA capacity of each inverter.

  • Batteries

These solar batteries are mainly for storing the charged electricity from the panels during the day. You may not need batteries for a solar water system.

This is because the water pump can work directly from the solar panels as stated above. It’s only needed when you want to pump water at night.

Thus, a good solar battery cost approximately ₦50,000 – 145,000 or more depending on the AH. Take note; the more batteries you have the higher the energy it retains.

So it’s basically the breakdown of the expenditures you see when you’re trying to set up a well-functioning solar water system. A good thing about a solar water system is that the cost of servicing is very low.

So if you can set up one, you’ll enjoy unlimited water in your homes, businesses, and elsewhere.
