A scientific study, conducted by researchers Kassem, Gökçekuş and Agila from Near East University, has investigated the solar energy potential and economic viability of grid-connected rooftop photovoltaic (PV) systems in three selected regions of Botswana. This study marks the first of its kind in the country. Utilizing NASA POWER data, the research assessed the solar potential in Gaborone, Maun, and Tshabong. Results indicate that these regions boast high levels of global horizontal solar radiation, rendering them suitable for various scales of PV system installation.
The study employed RETScreen Expert software to evaluate the techno-economic feasibility of the proposed PV systems. By analyzing the performance of different PV technologies, including mono-crystalline silicon and poly-crystalline silicon, the research assessed economic indicators such as net present value, annual life cycle savings, payback period, benefit-cost ratio, and cost of energy production. The findings suggest promising prospects for grid-connected rooftop PV systems in all selected locations.
Interestingly, the study reveals that PV projects utilizing poly-crystalline silicon technology tend to produce more energy at a lower electricity cost compared to those employing mono-crystalline silicon. This highlights the economic viability of PV systems in Botswana, indicating their potential to cover electricity demand and reduce carbon dioxide emissions, particularly in densely populated and rural areas.
The research underscores the significant role of grid-connected rooftop PV systems in Botswana’s energy landscape. It provides valuable insights and recommendations for decision-makers regarding the development and deployment of PV energy technology in the country. Overall, the study suggests that with effective utilization, solar energy holds immense potential to address Botswana’s current energy deficit.
