Publication - Appliance Impacts Over Time - Longitudinal insights from off-grid TV, refrigerators, & solar water pumps users
off-grid appliances changes over time. We captured critical indicators through phone interviews with off-grid TV, solar water pump, and refrigerator customers to track product quality, durability, satisfaction, impact, and uptake. Customers purchased appliances from 22 companies. Data in this report is categorized by product type and time since purchase. The customer cohort examined here is also represented in previous Efficiency for Access and 60 Decibels reports that explore the use and impact of off-grid appliances (electric pressure cookers, refrigerators, solar water pumps & TVs). This report specifically focuses on the change in impact over time. We recommend referencing the use and benefits reports together with this report for deeper insights. Where crucial, references have been made in this report. We derived most of the insights from mixed samples categorized by ownership tenure. However, a smaller subset of customers was interviewed for consecutive years, forming our ideal study. This smaller subset allowed us to examine perfectly linear and controlled ownership dynamics, contrasting them with our larger, general sample. Ideal study results have only been included where they differ from the broader sample or where they help to offer additional insights into theinterpretation of the general sample results.
