The Solar4Africa.org project started as "Kuyere!" in 2015:
Our current approach is the result of 7 years of innovation based on our continuing work in rural Malawian villages
A brief history
Where we are today: Maximizing customer benefit with affordable, very-long-lasting solar systems
It took many years of exploration and experimentation, but we have come to realize through our work that rural African customers benefit the most from clean energy when solar systems can last 10 to 20 years rather than just 2 to 4 years.
The key to producing a solar system with a 10 to 20 year lifetime is a new type of battery cell chemistry that has a cycle life that is ten times longer than lithium ion or lead-acid batteries. This battery chemisty is Lithium Titanate (LTO).
We are now committed to making highly affordable, African-assembled LTO-based off-grid solar systems widely available throughout rural Africa.
We are currently small, but we have ambitions to spread the knowledge and methods we have developed far and wide. We think that LTO-batteries can enable affordable, very-long-lasting solar systems not only in rural Malawi, but throughout rural Africa.
To this end, over the coming year we are hoping to develop partnerships with socially-minded solar implementers in Tanzania, Togo, Uganda, and Rwanda. Then over the coming decade, we hope to develop partnerships in many countries. Through these partnerships, we will strive to spread the benefits of "forever lasting" LTO solar batteries to millions of low-income households across rural Africa.
