MEI’s first large-scale solar heating project for Princess Noura University for Women in Saudi Arabia helped put the company on the map. Solar energy now provides hot water for over 40,000 female students each year. Completed in 2011, the project became the world’s largest solar heating system at the time. The solar water heaters will save 125 million kg of CO2 emissions over 25 years. Building on this success, MEI also helped hospitals and universities, such as Palestine’s Bethlehem University and Jordan’s German University, switch to solar energy for water heating and cooling.
