a division of SustainGroup

Headquartered in South Africa, SustainSolar focuses on business development across the entire African continent with current business activities in numerous Sub-Saharan countries.

About SustainSolar

African emerging economies are facing major challenges in reaching the UN Sustainable Development Goals, amongst which Goal 7 "Affordable and Clean Energy" is of very high importance. On the African continent, over 700 million people live without access to reliable and safe electricity. Sustainable Power Generation (Pty) Ltd. was founded in 2016 with the goal to respond to this need with high quality, decentralized and modular sustainable energy solutions using clean gaseous fuels and solar PV technology.

Made of world-class components, our solutions are designed and manufactured in Cape Town, South Africa, a leading logistics hub with major shipping lines connecting us to the world and excellent road network into the Sub-Saharan region.

Acknowledging the different contexts in which our customers operate, we formed two separate divisions: SustainPower our gas-to-power division and SustainSolar, our solar PV solutions division, each focusing on their respective technology and relevant market expertise to provide the best service to our decentralized energy clients across the continent.

SustainSolar Horizontal

Launched in 2018, SustainSolar strives to respond to the needs of emerging markets with clean, turnkey technology suited for various applications that require a decentralized, clean and dependable power supply.

Our containerised, pre-installed solar systems are equipped with top-quality solar PV modules and electronics including lithium-ion batteries and come in three standardized yet adjustable product configurations from small to large to suit a wide range of energy needs. Our production system and assembly facility are geared for once-off and bespoke projects and large-scale rollouts of mini-grids alike.

With growing activities, a good presence on the African continent, an expanding network of partners and the implementation of new projects, SustainSolar is a preferred equipment supplier for mini-grid, off-grid, hybrid fuel saving as well as mobile and rapid deployment solar applications. 

SustainPower started with the establishment of the company in 2016 with a focus on containerised, high-quality, durable solutions for sustainable power generation using biogas, landfill gas and natural gas, designed and manufactured in South Africa, with world-class components.

Biogas and landfill gas beneficiation are waste-to-energy technologies and therefore contribute to the sustainable use of resources and offer attractive business cases for on-site power generation in many industries such as food processing, agricultural and water treatment.

Decentralized natural gas to power solutions are a cleaner alternative to other fossil fuels for continuous off-grid power and with Combined Heat and Power (CHP) offer extremely high efficiencies. Prime power supply or emergency back-up supply running on gas contribute also to a smaller environmental footprint.

The SustainSolar Team

We are a team of Pan African and international experts striving to make a difference in the way developing economies generate power with the urge to fulfil our responsibility to people and the planet.
