Empower people with affordable and powerful clean energy can have a very strong impact on climate change mitigation!

The Lytefire solar thermal technology is meant to empower entrepreneurs, create sustainable jobs, support local stability and create more circular and functionnal service economy while contributing to minimizing the damage of climate change.

Lytefire is a brand of Solar Fire Concentration ltd, a Finnish based company. Solar Fire has also developed GoSol, a structure dedicated to projects with NGO’s including an important educational side.

The Lytefire as you see is the result of years of development by passionate people on the ground and engineers. The technology is based on the pioneering solar innovations of Mr Fraser Symington (1920-2014).
