We grow to empower people and decarbonize economies.

We are on a mission solve energy poverty in the Global South with Lytefire solar tech and empower people with trainings to create sustainable jobs.

The Lytefire solar thermal technology is meant to empower entrepreneurs, create sustainable jobs, support local stability and create more circular and functional service economy while contributing to minimizing the damage of climate change. Our projects are happening mainly in the Global South but since 2021, there is demand in EU and the Lytefire Deluxe is commercialized there to serve entrepreneurs with EU standards.

Lytefire is a brand of Solar Fire Concentration Oy (SFCO), a Finnish social and impact based company. We grow through an ecosystem of partnerships to empower people (users and partners) locally with Lytefire. Our humanitarian projects are run under the GoSol.org banner.

The Lytefire Tech as you see it today is the result of years of development by passionate people on the ground and engineers. The technology has been based on the pioneering solar innovations of Mr Fraser Symington (1920-2014) and abundantly implemented in the field by his grand-son, Lorin.

A tech without a vision isn’t much and the inspirational model of direct solar economy has been ideated by Eerik Wissenz.

Solar Fire Concentration as a social impact company has been founded in Finland by Eva & Eerik Wissenz, quickly joined by Urs Riggenbach, Will Cleaver, Lorin Symington and Arnaud Cretot.
