Case
Sun Carriers is a non-profit, non-governmental organization that seeks to equip entrepreneurs in
impoverished rural communities with solar panel energy amidst the country’s electricity supply
crises. Load shedding makes it difficult for entrepreneurs and small-scale farmers to operate
their businesses effectively. For example, perishable agricultural products are going to waste
because they are not adequately refrigerated.
Sun Carriers is taking on their first project, which involves a small fishing community in the West
Coast district of the Western Cape Province. Sun Carriers aims to build and install a
commercial1 solar information system at 10 businesses operating in the fishing and seafood
industry. The solar information system comprises the solar electrical panel and a mobile app to
monitor the panel. Sun Carriers could choose between two project ideas, Project-Alpha and
Project-Omega. Project-Alpha promoted outsourcing the design of the mobile app to a software
development vendor, Wemibono Software Solutions. Project-Omega explored the idea of
starting a special IT unit consisting of two network architects, two computer hardware
technicians, and two software developers. After adopting various tools to systematically discern
which project will be the best to pursue, Sun Carriers chose Project-Alpha.
Joe Ngqolomsila, an electrical engineer by trade and presently program manager at Sun
Carriers, will champion the design and building of the solar panels. According to Joe, the solar
panels can produce 250 to 800 watts per hour to power electrical appliances and storable in five
battery banks. The successful installation of the solar panel information system, according to
Ivan Solomons, the owner of a fish market in a small West Coast town and a project beneficiary
set to have a solar panel information system installed at his market, will greatly reduce
additional operational costs incurred by the fishing supply chain due to load shedding. Ivan, the
owner of a fish market in a small West Coast town and a project beneficiary set to have a solar
panel information system installed at his market, had the following to say about the impact of
load shedding on his business:
“From the moment fish are caught, they must be kept frozen at temperatures as cold as -
18°C to preserve the integrity of the product as it moves through the distribution chain to
the person who finally buys it in the shop. Because of load shedding, I had to throw
away huge amounts of seafood products as I cannot keep them refrigerated at a stable
temperature. And I do not have the funds to buy solar…”
Sherinique Arendse, appointed as a program manager from Wemibono Software Solutions,
believes that the solar panel mobile app will contribute to resolving the challenges faced by
Ivan. The mobile app provides real-time indicators, allowing users to check power output and
the money saved on the electrical bill due to solar energy. She states:
“I'm excited to announce that the mobile app will help Ivan monitor his business's
electricity supply from the palm of his hand. The app can remotely control smart
switches; both the solar panel and the battery pack have their own smart switches. For
the solar panel, users can remotely toggle electricity supply between power sources via
the smart switch. This means they can switch between the municipality power grid and
the solar panel. So, if load shedding is in progress and Ivan is not at the fish market, he

Commercial solar differs from residential solar in as much as a business building are bigger than residential ones
and contain more electrical resources that requires a bigger electricity supply (Finulent Solutions, 2022).
