Introducing the containerised, expandable solar solution for clean, secure, off-grid power for Africa


Up until quite recently, the number of people around the world without electricity was around one billion, and even though this figure is slowly being improved, it is still unacceptably high. In Central Africa, the overwhelming majority has no access to electricity, and in Sub-Saharan Africa, despite the share of the population with electricity rising steadily, rapid population growth means that the total number of people without access to electricity is on the rise to almost 600 million.


Accelerated progress and grid-alternative innovation is needed to ensure this number continues to fall. South African based Sustainable Power Generation, a rapidly growing African manufacturer of modular and  versatile containerised solutions for clean power generation, has partnered with Swiss-based PWRstation, to meet this need.


SustainSolar, Sustainable Power Generation’s solar alternative, is a highly versatile, mobile containerised solar power generation solution that is designed, manufactured, and installed in Africa by people from all over Africa, with Africa’s unique climate and environmental challenges in mind. Combined with PWRstation’s revolutionary extractable EXOrac™ system, they are now able to provide rural and off-grid applications with a safe, secure, and rugged solution that is mobile and able to deploy within seconds.


Says Tobias Hobbach, CEO and Founder of SustainSolar, “Access to electricity is a necessity for humanity: electricity is needed to make food, to power plants and equipment for industry, to make businesses and schools work. Access to electricity and energy storage solutions are vital for every field of life, from agriculture to commerce, from public services and health supplies to industry.”

PWRstation developed the industrial-class retractable racking system with unique design features which not only enable fast and easy solar asset deployment and redeployment, but are also perfectly suited for containerisation.


Malcolm Truman, PWRstation’s Business Development Manager says, “We are delighted to welcome Sustainable Power Generation on board as our new African partner. Our EXOrac solution is a perfect fit for their SustainSolar Rapid Deployment solar containers and the remote and rural off-grid markets they are intending to target with this solution. We are looking forward to collaborating with them at the launch of their solution and getting some projects off the ground.”

The benefits of SustainFlex:


  • Retractable accordion-style industrial-class racking system.
  • Easily transportable.
  • Flexible solution for ultra-rapid activation – within minutes.
  • Produces 5kWp using four individual EXOracs.
  • The rugged 10ft container houses inverters, and 10kWh of Lithium-ion batteries.
  • Easy to close and lock in case of security concerns, extreme weather, or fire.
  • Ideal for remote and rural off-grid applications, whether permanent or temporary.

Says Tobias, “SustainPower’s gas-to-power solutions are already trusted for the quality of their design, engineering, and manufacturing, and our commitment to only use world-class components. The Swiss EXOrac that PWRstation brings to the SustainSolar offering is a perfect alignment of our values and our positioning – exceptional African-strength design, backed with Swiss-precision components that are innovative and robust. SustainSolar’s containerised power solutions are ideal for rural mini-grids and off-grid, permanent or temporary applications, such as farms, lodges, government applications, clinics, schools, and so on. We’re excited to bring this rugged, safe, versatile solar solution to Africa.”

The launch of SustainFlex will take place at this year’s African Utility Week in Cape Town.

Says Tobias, “We’d like to invite the public to come and view the containerised, expandable rapid deployment solution at our stand L19, and meet the SustainSolar’s team to have any questions answered.”

With so much at stake with delayed and unreliable grid power expansion in Africa, it is good to know that true African-sourced power is still as rugged and innovative as ever.
