Off-grid refrigerator competition promotes solar energy

The Scaling Off-Grid Energy Grand Challenge for Development has announced the results of the 2016-17 Global LEAP Awards Off-Grid Refrigerator Competition, identifying the world’s best, most energy-efficient refrigerators designed for compatibility with off-grid solar energy systems.

SunDanzer who won in two categories, designed the DCR50 product specifically for submission into the Global LEAP Awards. The DCR50 requires just over 100 Watts to run for an entire day, substantially less than conventional refrigerator products, and offered the best value for money.

SunDanzer’s other winning product, the DCR165, uses energy most efficiently as determined by performance metrics including daily energy consumption and the time required to achieve and maintain a target temperature.

The purpose of the Global LEAP Awards is to incentivise innovation and identify best-in-class appliance products that are compatible with small-scale off-grid solar energy systems.

These products can help build demand and accelerate growth for solar household systems. Read more…

In addition to the two innovation prize winners, a third innovation prize will be awarded – for Appropriate Design and User Experience – following field testing in Uganda in early 2018.
