Skoonkrag is the renewable energy technology branch of MTC, an engineering consultation company specialising in technology transfer and simulation (mathematical modelling).

We can supply research, mathematical modelling and similar services at the forefront of technological development, but we also have partnerships allowing us to deliver standard services, such as solar power systems, measurement and verification of energy usage, energy management, etc.

What can we do?

  • Consultation on energy saving
  • Consultation on renewable energy
  • Renewable energy research (including pilot plants and experimentation)
  • Simulation/modelling of renewable energy technology
  • Energy management systems
  • Measurement and verification
  • Heating and cooling (HVAC)
  • Water heating
  • Water Purification
  • Lighting optimisation
  • Provide solar power solutions
  • Development of new products

Our Services

Please note: If you are interested in our services, funding is available through various government initiatives such as the National Foundry Technology Network (NFTN), the Department of Science and Technology (DTS), the Department of Trade and Industry (DTI), etc. We are registered suppliers at many of these initiatives, and have assisted some of our customers to obtain such funding which will allow you to access our services at a fraction of the price, or even at no cost. Please enquire if you are interested.

Research, development, mathematical modelling

We are able to do research both in terms of optimising and reducing energy usage of existing processes, and also in developing new products and systems. Some of the projects we have assisted in are listed below.

Vertical axis windturbine

Consultation project for the Vaal University of Technology. Efficiency of a vertical axis wind turbine was evaluated through numerical modelling, involving Computational Fluid Dynamics and rigid body motion.

Pump station analysis

Comprehensive analysis on pump station: pump characteristic curves and system design evaluation. Minor losses due to pipe system design evaluated through simulation.
Client was the municipality of Orania.


Heat sink for LED light

Simulation of a heat sink for a LED light, in order to verify maximum temperature, allowing designers to ensure a reasonable safety factor in operating conditions while keeping down material costs.
Client: Eco-synergy.

Renewable energy products

Through our partnership with suppliers of renewable energy and energy manegement systems, we supply a service focussed on industry and farming.

For industry we can supply a comprehensive service with attractive options that will save you on your electricity bill from the first day of installation (this includes financing options). We will do a comprehensive analysis of your electricity usage through our online metering systems, so that our proposal is based on actual quantitative data, and not a mere qualitative inspection. Please contact us if you are interested in such an audit.

  • We can supply financing and rebates for renewable energy products.
  • For a minimal capital outlay we can supply energy management systems that can save energy (sometimes 30% or more). This is an attractive option that will save you in electricity bills from the first day of installation.
