Solar Market Outlook in Nigeria

With a population of 200 million and an economy that relies mostly on its oil reserves, the economy of Nigeria is highly volatile. Add to that Nigeria’s electricity woes. Many residents and business owners in the country rely on generators to power up their business and even then a huge percentage of the population has no access to electricity. 

Experts agree that this shouldn’t be the case as this is a tropical country. Geographically, its location close to the equator means that it has mostly sunny days throughout the year. The government is hoping that this renewable energy source could be the solution they’re seeking to combat the electricity woes that have haunted them for decades.

The National Renewable Energy and Energy Efficiency Policy in Nigeria was established in 2014. This policy details that Nigeria has a target of 20% electricity generation from renewable sources, mostly solar, in an effort to address the nationwide electricity shortage. They are also hoping to encourage more private investments in solar power plants.

There is notably a high solar potential in Nigeria, which gets up to 7 hours of sunlight daily. If this sunlight can be harnessed, it will produce 333,000 MW of solar power, which should be more than enough to bridge the electricity gap in the country. 

Solar Energy Equipment Supply Capacity in Nigeria

Just as solar power plant projects are limited, there is also limited availability in local manufacturers of solar equipment in Nigeria. For those looking to make solar installations, you can turn to online or global suppliers and distributors for that. 

Top Major Seaports & Logistics in Nigeria

Transporting and logistics handling of solar equipment into Nigeria should be easy since there are plenty of commercial ports available such as

  • Lagos Port Complex,
  • Calabar Port Complex,
  • Delta Port,
  • Rivers Port Complex,
  • Tin Can Island Port, 
  • the Onne Port.

Shunt Regulators

Wholesale Shunt Regulator for PV Systems

Essentially, a shunt regulator — also known as a shunt voltage regulator (aka. charge controller)— is a form of regulator where the regulating element shunts the current to ground. By maintaining a constant voltage across its terminals, it takes up the surplus current to maintain the voltage across the load.

In terms of the basic operation of a shunt regulator, the load is operated with a resistor in series with the voltage source and the shunt regulator in parallel with the load. In order to keep the voltage across the load constant, a level of current must be drawn through the series resistor to maintain the required voltage across the load. The load will take some, and the remaining current is drawn by the shunt voltage regulator.

The circuit is designed so that at maximum load current, the shunt regulator draws virtually no current, and at minimum load current, the shunt voltage regulator passes the full current. As a result, it can be seen that shunt regulators are inefficient because the maximum current is drawn from the source regardless of the load current, i.e. when there is no load current.

Because of the purpose of the shunt regulator, this device has been considered as an essential element within the linear power supply technology.

Zener Diode Shunt Charge Controller

One of the most common and simple forms of shunt regulator is the simple Zener diode regulator circuit.

Its mechanism is very straightforward. Once over its small minimum current, the Zener diode maintains an almost constant voltage across its terminals. The series resistor drops the voltage from the source to the Zener diode and loads. As the Zener diode maintains its voltage, any variations in load current do not affect the voltage across the Zener diode. It takes up the current variations required to ensure the correct drop across the series resistor. In this way, it shunts sufficient current to maintain the voltage across its terminals and hence the load.

In the shunt voltage regulator circuit, the Zener diode must be capable of dissipating the power from the maximum amount of current it can handle. This is most likely to be a little more than the maximum current supplied to the load as the Zener diode will need to pass all the current when the load current is zero. Therefore, the total maximum current that will be passed by the diode is the load current plus an allowance for current to maintain the reference voltage when the load is taking its maximum current.

It should also be noted that for the shunt regulator circuit, the series resistance is comprised of the series resistor value, plus any source resistance. In most cases, the value of the series resistor will dominate and the source resistance can be ignored — but this may not always be true.
