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.

Electrical Disconnect

Wholesale Disconnects for Solar Systems

Essentially, safety disconnects allow users to rapidly shut down the system in case of an emergency. For this reason, disconnect switches are required to comply with electrical codes and pass inspection. 

A solar PV system usually has two safety disconnects. The first is the PV disconnect (or array DC disconnect). This kind of disconnect allows the DC current between the modules (source) to be interrupted before reaching the inverter. 

The second disconnect is the AC disconnect. The AC disconnect is used to separate the inverter from the electrical grid. In a solar system, the AC disconnect is typically mounted to the wall between the inverter and utility meter. This kind of disconnect may be a breaker on a service panel, or it may be a standalone switch. Additionally, it is sized based on the output current of the inverter. 

How to Size an AC or DC Disconnect?

Generally speaking, sizing refers to equipment, components, and connectivity (wiring) throughout a solar system as it relates to NEC requirements. The following terms are used to determine component output: 

  • Voltage
  • Circuit load
  • Amps or breaker size
  • Wiring or cables
  • Sizing and Protection of the AC Disconnect

NEC 690.10 stipulates that the circuit conductors between the inverter output and the building or structure disconnecting means shall be sized based on the output rating of the inverter. These conductors shall be protected from overcurrents in accordance with Article 240. The overcurrent protection shall be located at the output of the inverter. 

Important Features to Look For in Disconnect in Bulk?

Disconnects are incredibly useful for solar systems, and so, it is important to get the best possible disconnect for your own solar system. The following are the core features to look for in a disconnect: 

  • Offers bi-directional functionality, which breaks the arc regardless of normal or a reverse current flow
  • Includes all required components to meet NEC 690 requirements, including jumpers and labels
  • Guards against accidental contact with live parts with clear polycarbonate dead fronts
  • Available with modifications that allow customization to meet any application need
  • Sizing of Module Interconnection Conductors and DC Overcurrent Protection

According to NEC 690.80, where a single overcurrent device is used to protect a set of two or more parallel-connected module circuits, the ampacity of each of the module interconnection conductors shall not be less than the sum of the rating of the single fuse plus 125% of the short-circuit current from the other parallel-connected modules.
