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 PWM Regulator (solar charge controller)
Pulse width modulation (PWM) regulator is essentially a switch(aka. Solar Charge Controllers) that connects a solar array to a battery. The result is that the voltage of the array will be pulled down to near that of the battery.
PWM is arguably the most effective means to achieve constant voltage battery charging by switching the solar system controller’s power devices. When in PWM regulation, the current from the solar array tapers according to the battery’s condition and recharging needs.
Advantages of PWM Charge Controllers for PV Systems?
Charging a battery with a solar system is undeniably a difficult challenge.
In the past, simple on-off regulators were used to limit battery outgassing when a solar panel produced excess energy. However, as solar systems matured, it became clear how much these simple devices actually interfered with the charging process.
The history of on-off regulators has been full of battery failures, increasing load disconnects, and growing user dissatisfaction. PWM has recently surfaced as the first significant advance in solar battery charging.
PWM regulators make use of technology that is similar to other modern high-quality battery chargers. When a battery voltage reaches the regulation setpoint, the PWM algorithm slowly reduces the charging current to avoid heating and gassing of the battery — and yet the charging continues to return the maximum amount of energy to the battery in the shortest time. The result of this is a higher charging efficiency, rapid recharging, and a healthy battery at full capacity.
Additionally, the PWM charge controller promises some very interesting and unique benefits. These benefits include:
- Ability to recover lost battery capacity and de-sulfate a battery
- Dramatically increase the charge acceptance of the battery
- Maintain high average battery capacities (90%–95%), compared to on-off regulated state-of-charge levels that are usually 55%–60%
- Equalize drifting solar battery cells
- Reduce battery heating and gassing
- Automatically adjust for battery aging
- Self-regulate for voltage drops and temperature effects in solar systems
A great deal of testing and data supports the benefits offered by PWM regulators. Additionally, manufacturers are continuing their own ongoing test programs to refine the PWM charging technology. As a result, over time, each of these benefits will undoubtedly be improved and more clearly defined.
Are All PWM Chargers the Same?
Many solar charge controllers that simply switch FETs differently than the on-off algorithm claim to be PWM regulators. Buyers should be aware of this because this is actually not true. Only a few controllers are actually using a PWM constant voltage charging algorithm. The rest are switching FETs with various algorithms that are cheaper and less effective.
