Between 2015 -2021, in partnership with CLASP, we surveyed over 4,000 solar refrigerator, water pump and television customers across East, West and Southern Africa. Understanding these customers’ needs, experiences and satisfaction levels with off-grid energy appliance impacts over seven years provides strategic insights to support the growth of the nascent sector.

The ‘Appliance Impacts Over Time’ report presents the findings of this longitudinal study and offers an exciting opportunity to understand how customers’ relationships with their solar appliances change over time based on product quality, durability, satisfaction, impact, and uptake indicators. The data presented is categorized by appliance type and ownership tenure to produce specific and actionable insights, share feedback from consumers and signal opportunities for improvement.
