The Harmattan is a dry season that affects the production of solar power and photovoltaic systems in West Africa. This dry season is characterized by northeasterly winds carrying dust and sand from the Sahara Desert during the months of December to February and can

• reduce the amount of solar power and photovoltaic production.
• reduce the amount of sunlight that reaches solar panels, thus
• reducing their efficiency up to 20 percent in the production of solar power and photovoltaic systems. In addition, the dust and sand carried by the winds can accumulate on the surface of solar panels, further reducing their efficiency.
• The decrease in solar power and photovoltaic production during the Harmattan can have a significant impact on the energy production of West African countries. Without the proper measures in place, it can lead to energy shortages, increased costs, and disruption of essential services. Fortunately, there are several ways to minimize the impact of the Harmattan on solar power and photovoltaic production.

For starters, solar panels should be cleaned and maintained on a regular basis to ensure that they are free of dirt and dust. Finally, the use of lithium ion batteries and other energy storage systems can help to mitigate the impact of the Harmattan on solar power and photovoltaic production.
