Solar cold storage at a Kisumu market

Roughly a third of the vegetables sold at many Kenyan markets spoil before they reach a buyer. Achieng visits a solar cold room where traders rent shelf space by the crate and the day, and asks whether it pays for itself.

  • How the cold room is built: panels, batteries, insulation, a plain compressor
  • What a trader pays per crate and what she saves
  • Why the operator chose batteries over ice
  • The maintenance problem nobody budgets for
  • Achieng's verdict, and what would make this work in 100 more markets

Guest: Mama Akinyi, who has sold tomatoes at Kibuye market for 22 years.

Transcript
Welcome back to Sun, Soil and Silicon, I am Achieng Otieno. Today's technology is not glamorous. It is a cold room, a box with solar panels on top, sitting at the edge of Kibuye market in Kisumu. But it does something remarkable. About a third of the tomatoes sold at markets like this one used to rot before anyone bought them. Now the traders rent shelf space inside the box, by the crate, by the day, and the losses are tiny. I spent a morning with Mama Akinyi, who has sold tomatoes there for twenty-two years, then sat with the operator to ask the hard questions about batteries, maintenance and who is really paying. You are listening on Witspeak Podcasts. Let's open the cold room door.
