Solidge

In developing countries, electricity is often a luxury. People living in off-grid communities are not able to have a refrigerator, even though it is often the appliance they want the most. By integrating energy generation, storage and use into the same appliance, Solidge, an off-grid, solar-powered refrigeration system, solves grid unreliability by simply not using the grid. Solidge users can safely store food, unsold crops and vaccines for longer periods of time. Solidge will directly increase off-grid communities’ health and overall lifestyle by providing them with an affordable refrigerator. Solidge will first deploy in Morocco, taking advantage of the region’s sun and accessibility, as well as gather user feedback and refine Solidge’s design. However, Solidge has a broader mission. Designed from the ground up to become a globally deployable unit, Solidge will provide off-grid refrigeration for developing and developed countries alike.
