SolarCoin is a cryptocurrency that incentivizes a solar‑powered planet.
Earn 1 kSLR for every kilowatt-hour your solar panels generate. Solar energy is now the cheapest fuel in over 150 countries — we want to make it free.
The Transition — May 15, 2026
SolarCoin is moving to the Base network. Existing SLR holders receive kSLR automatically on May 30 — same value, better technology. The economics are unchanged: 1 kSLR per kWh, just like 1 SLR per MWh before.

We distribute kSLR as a reward for verified solar electricity production — 1 kSLR per kilowatt-hour on the Base network. When the value of kSLR exceeds the cost of producing solar electricity, solar energy becomes effectively free for producers.
We aim to accelerate the global energy transition.
Drive down the cost of electricity. Founded in 2013, SolarCoin’s long-term mission is to accelerate the global energy transition by creating an additional incentive for solar electricity production.
Our goal and 40-year mission since 2013 is to incentivize solar electricity production by rewarding the generators to reduce the cost of electricity production.
Solar energy is now produced at below US$12/MWh on some parts of the planet, and the cost keeps dropping.
As of today, cryptocurrencies are worth over US$2 trillion. Most of that value was distributed in exchange for carbon-intensive crypto mining. What if it was given out to people who produced energy for free?
