Walikale Engineering Africa was approached, through one of its directors, by a Partner to assist them in the design and implementation of photovoltaic and a thermal solar system at a student residence in Bloemfontein, Free State.

The request was made after an initial visit trough the facility to be supplied by both solar systems was conducted by The Partner. The task given were inclusive of energy analysis, demand analysis, facility study, complete system design, components identification and component purchase.

The design phase was conducted in April 2018. The implementation phase stated in May 2018 following the delivery of the purchase equipment.


The system powers the kitchen lights, passage lights, sitting room light, outside lights and toilet lights, selected plugs and includes a conversion of electric water heater to hybrid solar water heaters. The basic system requirement would be:

  • 13 X 300W photovoltaic panels
  • 11X 12V, 500 Ah lead acid battery for storage.
  • 2 SWH conversion Kits


Currently the PV system is suppling power to the targeted load in the residence and no issues have been reported so far.
The solar thermal system has been installed but not connected as principal source of hot water to the residence’s occupants.


The South African educational system is faced with multiple challenges that have an overreaching impact on the entire South African society as it is through education that a nation can achieve and maintain growth and development.

Some of the challenges include but are not limited to:

  • Lack of basic amenities, infrastructure and learning resources in South African townships and rural schools
  • Non-efficient use of resources with little accountability and transparency.
  • Limited basic pedagogic and content knowledge competencies from a large number of teachers needed to impart the skills needed by learners specifically in math and science related subjects
  • No culture of reading from learners and a lack of motivational push to learn from the community and families
  • There is a shortage of experienced and trained math and science teaching staff in disadvantaged townships and rural schools
  • Limited or non-existent exposure to new technologies with their potential.


Following the above-mentioned difficulties, we at Walikale engineering Africa propose an innovative solutions to alleviate some of the challenges faced by schools in disadvantaged and rural areas. The solution aims at providing learners an outlet where they will be exposed to information and communication technologies, could interact with competent and experienced tutors and interact with learners from other parts of the country (or the continent) sharing and discussing experiences. Additionally, with the use of renewable energy to power the proposed system we aim to inform and inspire the young generation on the use and importance of renewable energies technologies.


The primary objective of the proposed system is to provide high school learners access to experienced tutors to complement the teaching obtained from normal school activities. Schools in townships and especially in rural areas where access to computer and internet connectivity limiting the learners’ exposure to the highly important technological advances of the current century is a major disadvantage and obstacle for a transformed post-colonial and post-apartheid society.
