“With a population of 17.6 million people, [Malawi] lags behind much of the world on energy access with just 11 percent of its population having access to grid electricity. And for those who are connected to grid power, supply remains largely unreliable. Accelerating energy access has clear benefits through direct impacts on poverty eradication, climate change, health, water and economic transformation.”
(United Nations, 2019)
Beehive’s Main campus in Chilomoni, Blantyre, was imagined as being a world-class hub for youth education and training, and a source of job creation in a community severely lacking employment opportunities. In order to achieve this goal, provision of a reliable electricity supply was vital, in order to create permanent access to computers and the internet, and sufficient lighting when required.
Opened in 2009, the Beehive Main Campus was originally powered by a diesel-run generator whenever the mains electricity supply became unavailable. Costly and contrary to the sustainable message promoted by Beehive, the generator was superseded by a solar array in 2018. The solar array system comprises 315 individual photo-voltaic solar panels, orientated at the optimum angle for their global location, to output a total of 93KW of energy at their peak, more than enough to power every computer and sewing machine on campus. When the sky is overcast, 24 lead-acid batteries are automatically engaged to provide a total of 48KW of power, enough to power the entire campus for approximately one working day. Two high-tech invertors are required to allow energy collected from the solar panels to take one of two different routes simultaneously; firstly directly to the buildings’ electricity lines, and secondly to charge the batteries.
