“High operating temperatures, dust deposition and inconsistent policy frameworks remain the most persistent barriers to PV performance in Sub-Saharan Africa,” the authors wrote . The review notes that crystalline silicon modules — the most widely used PV technology — can suffer 15–20% efficiency losses under such heat stress due to declining voltage output. Sub-Saharan Africa receives less than 2% of global renewable energy investment, despite having some of the world’s highest solar potential, the researchers noted. Around 600 million people in the region still lack access to electricity, making solar power a critical development tool — but one that requires stronger governance and support systems. The review concludes that solar power remains essential for Africa’s energy transition, but its long-term success will depend on combining technology adaptation with stronger investment and regulatory coordination.
