Lytefire - Fire from Sunlight

We make clean energy affordable for all with solar thermal concentration.
For a fair and liveable future.




This campaign exists because we are on a journey to make the energy from direct solar concentration the new normal.

We are crowdfunding now with a multidimensional campaign because it’s a climate change CRISIS and we want to accelerate the global spread of a proven and powerful solution.

Make a long lasting sustainable impact and support one entrepreneur to go solar, push the limits of solar with pioneers, pre-order your Lytefire 5, build yourself or support the creation of more online material, donate directly to our project with Plan International, or invest in a Climate Victory Bond.

Spreading Lytefire built locally with local materials together with powerful educational material can empower millions and have an amazing impact.

In 2019, IPCC scientists stated that we have 12 years to miminize climate change caused by humans activities.
We have to hurry.

We are a Finnish social and impact family company. Our international and passionate team is working in the field in 12+ countries since a decade to refine a powerful and locally built solar thermal device.

Donate to our project with Plan International in Uganda

If you wish to support an association, you can donate directly to the NGO Plan International and help spread Lytefire in Uganda.

We partner with non-profits who have ongoing local presence, relationships and programs to build skills for sustainable livelihoods. Our partnership with Plan International started in 2018 when we launched training youths to become solar entrepreneurs.

Better access to cleaner energy is only part of a broader solution to poverty. It is also essential to build the critical skills to maintain our technology, learn how to bake or roast, and learn the fundamentals of how to run a business. Finally, entrepreneurial success for new businesses should be supported by monitoring and coaching.

Invest in Climate Victory Bonds

Massive action is needed to set the world on a pathway to fix the climate, be sustainable, and solve poverty. With the climate bond we are enabling investments to maximize the impact of Lytefire. Viral, local solar thermal can deliver a large scale energy shift in the short time we have to minimize the damage of climate change. Click here to learn more about investments.


We are on a mission to solve climate change and energy poverty
while accelerating the adoption of clean and decentralized energy for all.


Lytefire is an initiative to maximize the impact of solar thermal energy. It was initiated by the GoSol Team in 2020, after fully developing and piloting our solar technology on 4 continents. With Lytefire, we are offering our products on pre-order and we are releasing open source construction guides to support the global adoption of our technology.

Lytefire and GoSol are run by Solar Fire Concentration Oy, a Finnish social and impact enterprise created in 2012 in Tampere, Finland.
