SOLAR-POWERED COLD STORAGE SOLUTION FOR SUSTAINABLE FISH PRESERVATION IN OFF-GRID COMMUNITIES

A CASE STUDY OF KENDU BAY AND SORI BEACHES IN HOMA BAY AND MIGORI COUNTIES, KENYA

Abstract

Post-harvest fish losses remain a significant challenge in Sub-Saharan Africa, with nearly half of total fish production wasted due to inadequate preservation infrastructure. In Kenya, small-scale fish traders (SSFT) in off-grid areas such as Kendu Bay and Sori Beaches located in Homa Bay and Migori Counties respectively, experience up to 70% post-harvest losses due to limited refrigeration options and the high cost of ice storage. This study aimed to evaluate the feasibility, economic sustainability, and adoption potential of a solar-powered cold storage system (SPCSS) as the renewable solution to these challenges. Guided by the Technology Acceptance Model, the study employed a mixed-methods approach, incorporating structured interviews and field observations from 70 purposively selected fish traders. Data were analysed using thematic coding and cost-benefit assessment to determine viability. Results indicate that traditional preservation methods significantly reduce profit margins, while renewable-powered alternatives can extend shelf life, reduce waste, and boost earnings. The study recommends targeted support from government agencies, Non-governmental Organizations (NGOs), and private investors to scale solar-powered storage in fishing-dependent, off-grid communities. These findings underscore how clean energy innovations in enhancing food security and economic resilience among small-scale fish value chain actors.
