Status

Solar Ear is a social business that started in Botswana in 2002. Now headquartered in Canada, the company manufactures low-cost, environmentally-friendly hearing aids and solar-rechargeable batteries. Solar Ear employs and trains people who are deaf to manufacture the hearing aids and to lead the replication of the technology in other countries. The company also runs social programmes, including a holistic hearing-loss detection and education programme. Solar Ear had sales of more than $15 million in 2017, exports to 60 countries, and entered the Russian market in 2018.

Solution

Globally, only 10 per cent of people who need hearing aids have access to them. Key barriers are the cost of the devices and batteries and their lack of availability in rural communities.

The key benefit to Solar Ear hearing aids is that their batteries are rechargeable using solar-powered chargers and last two to three years, compared to the seven to ten days of some single-use batteries on the market. This reduces the environmental impact as well as the cost, making the products affordable to 80 per cent of those who need them. Importantly, in addition to working with their own products, the rechargeable batteries work in 95 per cent of hearing aids on the market. Solar Ear technology has been approved by the US Food and Drug Administration, the World Health Organization, and the European Union.

All Solar Ear hearing aids and batteries are manufactured by deaf people working in Botswana, Brazil, and China; and a third of the profits from sales are used to run social programmes. To date, Solar Ear has supported over 50,000 children to receive a low-cost hearing aid, and thus to have the ability to attend school. The company has also developed a programme to fight hearing loss through detection, research, education, equipment, and technology (the DREET programme).

Impact

• Between 2002 and 2018, Solar Ear sold more than 50,000 hearing aids, 100,000 solar chargers, and 250,000 rechargeable batteries.
• Solar Ear’s deaf-to-deaf HIV education programme in Botswana reduced the HIV/AIDS rate in the deaf community from 38 per cent to 10 per cent.

Goals

Solar Ear has already replicated its initiative in several countries and has plans to enter India in 2019. The technology is not patented, and Solar Ear works with partners who share their mission to replicate. The company also helps local partners to write business plans and raise funds; and once operations are on track, the project is 100 per cent locally owned and operated. Technical training in new countries is led by a team of deaf workers from Botswana. Further, Solar Ear is developing a franchise model for future growth, based on a 10 per cent fee on sales, and is developing a hearing test using Android software on mobile phones.
