Amid climate change, appliances such as fans can be lifesaving, especially for women and the elderly who traditionally spend more time at home. Many people who need fans do not currently have access to them. Compared with other technologies, such as air conditioners, efficient, solar-powered fans are a low-cost and practical solution to keep people cool. They are accessible for people with low incomes and better suited to those living in rural areas that are not connected to the national electricity grid.
In Pakistan, people are increasingly having to adapt to scorching heat for eight months of the year, with temperatures expected to rise faster than the global average from climate change. Over 25% of people in Pakistan live off-grid and the energy grid is notoriously unreliable. It is also estimated that in Pakistan and Bangladesh, 15 – 30% of people still lack access to electricity.
As such, fans must run for 18-20 hours a day to avoid dehydration and help children sleep. Many existing fans are inefficient and expensive to run. The Efficiency for Access Research and Development Fund, managed by Energy Saving Trust, awarded Harness Energy, Pakistan a grant to develop highly efficient solar-powered fans for use in rural and hard-to-reach areas.
This fan can be powered by a 12V solar system, any battery or an AC/DC adapter, and is also more energy efficient than other fans on the market. It uses a highly efficient motor (brushless DC) that conserves energy and increases the lifespan and reliability of the product.
