Solar Market Outlook in Senegal
A partnership between the World Bank, IFC, the European Investment Bank and Proparco has worked together to finance two solar PV plants in Senegal. This solar project is projected to provide clean and sustainable power from solar sources for more than half a million Senegalese residents.
The two solar plants mentioned above were launched in May of 2021 with a total solar capacity of 60 MWac. The plants will generate energy with a tariff making it one of the cheapest electrical costs in the Sub-Saharan region of Africa. But apart from the access to affordable and sustainable energy, it’s the ability to reduce carbon emissions by 89,000 annually that will be the biggest benefit of installing these new plants.
The two projects are a result of the auctions that were tendered by the Senegalese government through the Energy Regulatory Commission. Despite the growth in the number of residents in the country that now has access to power, there is still a significant amount of them that lacks access to electricity. But things are looking up with the affordability of solar power especially since the previous source – fuel imports – was too costly for the economy to sustain.
Solar Energy Equipment Supply Capacity in Senegal
The availability of local suppliers of solar power in Senegal is rather limited. However, there are plenty of local and online suppliers of solar power equipment to small- and large-scale installations.

Senegal benefits from its exceptional location that facilitates efficient and easy logistics and trade activity. It has many functioning ports used for commercial activity such as Dakar, Thies, and Ziguinchor.
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:
- 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.
