The cost of solar panel systems now in Nigeria is a reflection of the nation’s increasing preference towards the use of solar energy.
A rising number of Nigerians are considering solar power as a potential option in light of their concerns about climate change and the need for stable and sustainable energy sources.
What Are Solar Panel Systems?
With the use of photovoltaic cells, solar panel systems are machines that turn sunlight into electricity. Photons from sunlight are absorbed by layers of semiconductor materials in these cells, which then transform them into electrons. After that, the electrons can be used to generate electricity.
The most popular kind of solar panel system is composed on grid-like arrangements of crystalline silicon cells. Wires that carry electrical current to an inverter connect these cells, which are encased in glass or plastic sheets.
Types Of Solar Panels
Three types of solar panel systems are available for residential solar energy systems now on the market: thin film, polycrystalline, and monocrystalline solar panels.
The solar panel systems are made with varying qualities and costs differently according to the kind of solar cell used in them.
1. Monocrystalline Solar Panel Systems
The purest solar panel systems are those composed of monocrystalline silicon. Their rounded edges and consistent black appearance make them easy to identify. This kind of solar panel system has one of the greatest efficiency rates due to the excellent purity of the silicon; the most recent models have efficiency rates above 20%.
The longest-lasting, highest-power-output, and least-space-consuming panels are monocrystalline ones. It goes without saying that this makes them the priciest of the group. An additional benefit to take into account is their tendency to be marginally less impacted by elevated temperatures in comparison to polycrystalline panels.
2. Polycrystalline Solar Panel Systems
These solar panels are easy to identify since they are square-shaped, have uncut angles, and have a speckled, blue appearance. Compared to monocrystalline panels, they are created by melting raw silicon, which is a quicker and less expensive technique.
Because they are more susceptible to the effects of heat, this results in a cheaper end cost but also lower efficiency (around 15%), lower space efficiency, and a shorter lifespan. However, there aren’t many distinctions between mono- and polycrystalline solar panel types, and your decision will mostly rely on your unique circumstances. Power outputs are essentially the same with the first option, but it delivers a little superior space efficiency at a slightly higher cost.
3. Thin-film Solar Panel Systems
Thin-film panels are easily recognised by their thin look, as their name implies. Compared to panels that employ silicon wafers, these panels are around 350 times thinner. However, thin-film frames can occasionally be quite big, which can mimic the look of a monocrystalline or polycrystalline system across the solar system. Depending on what kind of material they were made of, thin-film cells can be either blue or black. Consider looking into thin-film if you’re searching for a less costly choice. One or more films of a photovoltaic material—such as silicon, cadmium, or copper—are applied on a substrate to create thin-film solar panel systems.
How much does it cost?
In Nigeria, solar panel systems can cost anything from N50,000 to N150,000. However, a number of variables, such as brand type, size, and power capacity, affect this price. Higher power capacity, larger panels are typically more expensive than their smaller equivalents.
The crystalline structure and rating determine the cost of solar panel systems in Nigeria. You would have to pay more the higher the rating. The rating indicates the voltage and wattage that the solar panel systems are capable of producing. The various solar panel systems sizes and their associated costs would be listed below.
- 140W Polycrystalline Solar Panels for N33,000
- 130W Polycrystalline Solar Panels for N35,000
- 100W Polycrystalline Solar Panels for N30,000 to N55,500.
- 80W Polycrystalline Solar Panels for N22,000.
- 60W Polycrystalline Solar Panels for N15,500.
- 50W Polycrystalline Solar Panels: N20,000–N45,000.
- 40W Polycrystalline Solar Panels for N15,500.
- 30W Polycrystalline Solar Panels for N12,000.
- 20W Polycrystalline Solar Panels: N12,500–N20,000.
- 15W Polycrystalline Solar Panel for N12,000.
- 10W Polycrystalline Solar Panel: N12,000 – N20,500
- Single Crystalline 130W Solar Panels for N25,000.
- 2 x 100W Mono Crystalline Solar Panels for N40,000.
- 2 x 80W Mono Crystalline Solar Panels for N30,000.
How Long Can A Solar Panel Last?
Solar panel systems can last up to 30 years or longer if they receive regular maintenance. This does not imply, however, that they cease to produce electricity after this time.
Rather, with time, their effectiveness progressively declines. The system’s inverters may need to be replaced every ten to fifteen years because they usually have a shorter lifespan than the panels.
Benefits Of Using These Panels
- Reduced Electricity Bills: By lowering reliance on grid power, solar panel installation for a home can result in significant savings on electricity bills.
- Good for the environment: solar energy is a clean, renewable energy source that doesn’t release any harmful emissions.
- Boost Property Value: Because solar panel systems are sustainable, homes equipped with them may be more valuable when they go up for sale.
