Solar Cold Storage Container

At the beginning of December 2024, the VoltaViewAfrica team has installed and put into operation the first solar-powered cold store container in the village of Sintet, near the town of Kalagi in Gambia. This project is financially supported by the Annegret and Dr. Karl-Heinrich Hasenritter Foundation. It supports the local “Sintet Women Garden”. The women there grow onions, which are traded on the market in spring at significantly better prices. Thanks to the solar-powered cold storage facility, the onion harvest can be stored fresh for a longer period of time, allowing the women to generate significantly improved profits for their harvest.

The container-based cold store is equipped with a solar roof with a peak output of 8 kWp and a new type of sodium-ion battery storage with a capacity of 12 kWh. The volume is 32 m³ and the temperature in the cold store can be adjusted between 5-10 °C as required.

The Watoto wa Africa Orphanage

The Watoto Wa Africa orphanage in Mwanza/Tanzania is an institution in great need, as it has no or only irregular electricity and no drinking water. Its only source of water is the collection of rainwater in large tanks. In spring 2023, there was a typhoid epidemic with fatalities. To support the orphanage, VoltaViewAfrica will install a Powerhouse by the end of this year, which will provide electricity and clean drinking water for the orphanage. This project is supported by the Rotary Club of Goslar.
