SolarCoin Vision

The global clean energy transformation needs acceleration. Energy technology is not the issue. Solar Energy is now the cheapest fuel in over 60 countries.

SolarCoin’s vision is to incentivize a solar-powered planet. Rewards drive action. SolarCoin helps build a foundation the global energy transition by rewarding solar producers with an energy-referenced currency. Economic research on SolarCoin is here.

The goal is to incentivize solar electricity by rewarding the generators of solar electricity to reduce the cost of electricity production.

Introducing SolarCoin

SolarCoin is a reward for solar energy producers. The SolarCoin Foundation gives energy producers blockchain-based digital tokens at the rate of one SolarCoin (SLR) per Megawatt-Hour (MWh) of solar energy produced.

SolarCoin is free. It is an additional reward for solar energy producers. It is separate from other incentives such as government subsidies or carbon credits. Whoever produces solar power may receive SolarCoin.

SolarCoin is like air-miles for solar electricity generation – only better because it isn’t tied to one company.

SolarCoin is global, decentralized, and independent of any government. The distribution part of the project is designed to last 40 years. SolarCoin is spendable and tradeable just like a cryptocurrency but focused on incentivizing real-world environmental activity: verifiably produced solar energy.

How It Works

Earning SolarCoins

Any size Solar energy producers freely submits a claim with a SolarCoin Affiliate to register their solar installation. Claimants download a free SolarCoin wallet to create a receiving address that acts like a bank account. This address and some solar facility data and documentation are shared with the Affiliate.

The SolarCoin Foundation then sends SolarCoins to the Claimant’s wallet at a rate of 1 SolarCoin per 1 MWh of verified electricity production. Claimants can save, exchange, or spend SolarCoins as they wish, and may receive ongoing grants over the next 20-30 years they generate energy.

97.5 billion non-circulation SolarCoins have been created for energy producers.

Spending SolarCoins

SolarCoins are sent to addresses (accounts) in digital wallets and used as currency, or can be stored long-term in offline (paper) wallets. SolarCoin can be traded for government currencies on cryptocurrency exchanges, or spent at businesses that accept them. Find more answers in our policy paper and the FAQs.

Claim Your Free SolarCoins

SolarCoin awarded on the basis of actual production data. A few data points a year are required from a monitoring system or platform to verify energy produced.  Many of the world’s largest platforms are in the process of verifying SolarCoin. If your energy monitoring platform doesn’t verify SolarCoin, reach out to an affiliate and they will work to enroll your platform.

Two grant calculation methodologies are used: actual, based on kWh’s generated, and estimated, based on a percentage of an installation’s nameplate capacity.

Most producers and platforms use the actual granting method, where every 1 MWh generated gets one SolarCoin, e.g. 1,100 kWh = 1.1 MWh = 1.1SLR.

In some cases actual production data is difficult to retrieve, so estimated grants are delivered. SolarCoins are granted at the rate of 15% of the installed rated DC nameplate capacity per year using an industry standard algorithm.  To estimate a grant, the nameplate capacity of the installation (in KW) is multiplied by 1.31, e.g. 5KW x 1.31= 6.55MWh = §6.55 SLR.

The initial SolarCoin grant is retroactive to the interconnection date of the facility or Jan 1, 2010 – whichever is most recent. Registration approval confirmation & SLR granting currently typically occurs the first week of each month. This can occur as quickly as 2-3 days if your platform is a SolarCoin partner. After the initial grant, follow on grants are delivered every 6 months following the initial grant for the life of the energy generation project.

SolarCoins can be claimed via automatic data import, by submitting paper documentation using our web interface, or via any registered SolarCoin Affiliates. The SolarCoin Foundation requires large-scale facilities (over 500 kW) to submit their claims via an Affiliate.

SolarCoin: Accelerating the Energy Transition


During this year’s highly successful Intersolar Europe, SolarCoin founder and self-confessed “recreational central banker” Nick Gogerty found time to sit down with Impact4All to discuss how “the first digital currency that rewards solar electricity generators” is helping accelerate the unstoppable transition to renewables. During the interview, Nick covers a wide range of topics detailing the philosophy behind the coin and its potential for impact in the energy transition.

The SolarCoin Ecosystem Participants

The SolarCoin Foundation

SolarCoin was created in 2014 as an open community project run by volunteers and the SolarCoin Foundation a Delaware (U.S.A) registered Public Benefit Corporation. The SolarCoin Foundation PBC co-founders are Nick Gogerty and Joseph Zitoli.

SolarCoin claimants

SolarCoin claimants are companies or individuals who apply for and claim their free SolarCoin. They receive them for verified energy production going back to January 2010. They can spend, save or donate their SolarCoin any way they wish.


The SolarCoin Foundation works closely with affiliates who help to verify SolarCoin claims information. Affiliates are usually organized as for-profit companies who receive SolarCoins from the SolarCoin Foundation for each claim they verify and facilitate for claimants. Affiliates may also offer separate services to their customers. Claiming SolarCoin is always free of charge, but affiliates may offer additional services.

Our Community

At SolarCoin we want to help accelerate renewable energy production. We’re creating a community with a shared vision and passion for this 40 year mission.
