Many health facilities in remote areas operate without grid electricity, have unreliable electricity, or find that using electricity is too costly. In these settings, solar energy is a promising solution for powering the storage and transportation of vaccines and heat‐sensitive drugs at controlled temperatures. Project Optimize, a collaboration between the World Health Organization and PATH, has been working with public and private partners on several solar technologies tailored to the following local electrical power conditions: unavailable or unreliable power, intermittent power, and reliable power.
