Solar-powered bakery gives life to community

Despite being ranked as the eighth most developed country in Africa in the United Nations Development Programme’s annual report in 2018, several challenges still plague South Africa. The need for employment, access to energy, economic activity, community development and access to affordable essential foods is still very prominent in both rural and urban areas.

While working on a project to empower a remote village in the Northern part of South Africa through enabling energy access and community development from locally available renewable energy sources, Profs Johan Meyer and Sune von Solms of the University of Johannesburg’s School of Electrical and Electronic Engineering Sciences conceptualised the Solar Bread Box – a first for commercial sized photovoltaic solar bakeries.

Boasting the same equipment and baking cycle as a standard grid-tied commercial bakery, the Solar Bread Box eliminates the dependence, purchase and monthly bills associated with grid-tied electricity. Not only that, but the bakery is also an instantaneous employment and skills development opportunity for youth, a tool for economic stimuli, and an avenue for an essential product.

Low income households in rural and urban communities where there is no grid connection; communities where the residents cannot afford electricity; or communities where there are underlying social issues regarding the access and distribution of electrical power consider bread an every day staple or meal. The affordability and access of wholesome, fresh bread is essential in such areas.

Prof. Meyer clarified that the Solar Bread Box should not be confused with other solar solutions such as concentrated solar power or solar thermal technologies that are used for heating and cooling. He explained that the Solar Bread Box uses a photovoltaic system, which converts solar energy into electrical power used for the baking process.

Prof. von Solms explained that the idea is for the bakery to function on the conversion of solar energy as much as possible – minimising the cost of solar energy storage solutions. This means that baking will be seasonally dependent, and bakers will have to adjust their baking times in accordance to the sun to harness maximum power during baking cycles.

Contrary to traditional community development activities which normally consist of agriculture, tourism and niche manufacturing, the commercial sized bakery is ideal because:

  • The operation and income are immediate.
  • It is a sustainable business with vast opportunities for growth.
  • It is not dependent on grid-tied electricity as it harnesses the power of the sun.
  • It immediately avails job opportunities in communities.
  • It fosters skills development, micro business and enterprise development.

The UJ School of Electrical Engineering in collaboration with Bakery and Food Technology Incubator of South Africa (BICSA), offers training on how to bake, run a bakery as a business and how to maintain a solar PV system – enabling communities to thrive independently.

So far, the Solar Bread Box has sparked economic activity, created jobs for eight individuals, created an enterprise that now serves neighbouring villages, created the access to wholesome foods, the production of at least 100 loaves of bread a day, and boosted skills development in Gwakwani – a small remote village in Limpopo, South Africa that initially had no grid connection.

When used as a tool for community development, the Solar Bread Box becomes a self-sustaining, economy stimulating, job creating and skills development platform – creating communities that have access to healthy, wholesome baked goods, are self-dependent and economically active.
