This third report in the "Solarize Africa Market Report" series investigates current developments on the African continent in general and 16 African national PV markets in detail.

Electric cooking with solar energy is on the rise as both solar and battery technologies continue to improve, making it viable for off-grid homes. One of the main hurdles for solar-powered electric cooking has been energy storage. Cooking typically requires a large amount of energy for a short period, while solar generation is intermittent. However, advancements in lithium-ion and solid-state battery technology have made energy storage more efficient, allowing for cooking after sundown or on cloudy days. The efficiency of electric cooking appliances has also improved: In induction stoves, for example, most of the energy goes directly into heating the pot or pan. Appliances like electric pressure cookers and slow cookers are also energy-efficient. They can be ideal for solar-powered cooking setups, as they require a relatively low, steady energy input over a long period of time. With continuous advancements in solar PV and battery storage, solar electric cooking is likely to spread further in regions where grid access is limited or costly, such as parts of Africa, South Asia, and Latin America. In off-grid areas with limited access to electricity, PV systems are also key for powering refrigerators, freezers, refrigerated containers, and cold rooms. They are particularly valuable in rural or remote settings for storing perishable goods, medicines, and vaccines. New technological developments have significantly increased the efficiency of solar refrigeration systems, minimizing or even eliminating the need for battery power at night and during periods of low sunlight.Solar energy can also be used to purify or treat water to make it safe to drink or for agricultural or industrial use. This method leverages the power of sunlight, either directly or indirectly, to remove contaminants, pathogens, and impurities from water. There is a variety of methods for solar water treatment, ranging from using the sun's UV-A rays and heat to complex solar-powered water filtration systems where PV-generated electricity is used to pump water through advanced filtration systems such as ultrafiltration or RO (reverse osmosis). However, solar water treatment systems are still costly and require advanced technology and expertise.This session will provide an overview of current developments and insights into new applications for solar-powered cooking, cooling and water treatment.

Floating solar holds significant potential in regions with abundant water bodies, but practical challenges and high costs have tempered expectations in Europe. While technological advancements are gradually improving feasibility, and companies are even looking for new solutions, such as hybrid-offshore systems, navigating the complexities of deployment, reliability, and financing remains critical for long-term success.This session will discuss:Overview of floating PV market developmentsChallenges, lessons learned and innovative approachesEnvironmental implications of FPV applicationsTechnology innovations & standardization developmentsCost reduction strategies and financing solutions
