What SolarCoin does
SolarCoin Foundation is a nonprofit organization that operates a blockchain-based cryptocurrency rewards program designed to incentivize solar electricity production worldwide. Launched in December 2013, the foundation distributes kSLR tokens at a fixed rate of 1 kSLR per kilowatt-hour of verified solar generation, currently running on Coinbase's Base L2 network with a full migration from the legacy Energy Web Chain (SLR) scheduled for May 15, 2026. The program serves over 30,910 verified solar installations across 139 countries representing 3.47 GW of nameplate capacity, with Germany the largest national market (12,423 installations) and 92% of installations residential. The co-founders are Francois Sonnet and Nick Gogerty; the foundation operates with 1–10 staff augmented by a long-standing volunteer community.
The core technology stack combines two blockchain networks (kSLR on Base as the primary forward chain; legacy SLR on Energy Web Chain) with a multi-layer verification pipeline that cross-references inverter telemetry from major monitoring platforms (SolarEdge, Enphase, SMA Sunny Portal, Fronius, Huawei, GoodWe), satellite imagery for larger installations, identity documents, and automated anomaly detection. A REST API enables B2B partners to submit generation data and trigger automatic monthly reward distribution, and an Omnibus Account managed-wallet option reduces onboarding friction for non-crypto-native users.
The business model is nonprofit and usage-based: participation is free for solar owners, there are no signup or subscription fees, and the only economic mechanism is a 10% network development fee deducted from minted kSLR rewards. Go-to-market combines a self-serve registration portal (claim.solarcoin.org), community-led adoption, and channel partnerships with energy companies, inverter OEMs, and monitoring platforms. Strategic anchors include ACWA Power (first utility-scale adopter), SMA Sunny Portal integration, and membership in the IRENA Coalition for Action and the Global Solar Council. Token liquidity is provided via CarbonSwap for kSLR and DigiFinex, Uniswap, and SushiSwap for legacy SLR pairs.

SolarCoin product offering
Product offeringCore offering
SolarCoin Foundation distributes kSLR (kiloSolarCoin) cryptocurrency tokens as rewards to verified solar electricity producers at a rate of 1 kSLR per kilowatt-hour generated. The foundation also offers a B2B Partner REST API and Partner Dashboard that allow energy companies, inverter manufacturers, and solar monitoring platforms to integrate SolarCoin rewards into their own products, enabling automated reward distribution to their customers.
Product overview
SolarCoin is a global cryptocurrency rewards program that incentivizes solar electricity production. The product ecosystem consists of the kSLR token (the primary digital token on Base network rewarding 1 kSLR per kWh of solar generation), the legacy SLR token (on Energy Web Chain, being phased out), the Partner Dashboard (for B2B partners to manage claims), the Migration Portal (for transitioning from SLR to kSLR), and the Omnibus Account option (a managed wallet service for users who prefer not to handle their own crypto keys). The program integrates with major solar monitoring platforms (SolarEdge, Enphase, SMA, Fronius, Huawei, GoodWe) for automated production verification and lists on exchanges including CarbonSwap, DigiFinex, Uniswap, and SushiSwap.

Products and services
- kSLR (kiloSolarCoin) Token Primary cryptocurrency token on the Base network that rewards solar electricity production at a rate of 1 kSLR per kilowatt-hour verified. Users earn tokens for verified generation, hold them in their wallet, trade them on exchanges, or spend them at partner businesses. kSLR has real market value and is tradable on cryptocurrency exchanges.
- SLR (SolarCoin) Legacy Token Original SolarCoin cryptocurrency token on Energy Web Chain. SLR has been superseded by kSLR on the Base network but legacy SLR remains viewable and tradable on supported exchanges. SLR holders receive kSLR automatically via snapshot mechanism during migration.
- Omnibus Account Managed wallet service provided by the SolarCoin Foundation where tokens are held in a secure, pooled account on behalf of users. Recommended for beginners; requires no technical knowledge, no wallet software installation, and eliminates risk of losing private keys.
- Partner Dashboard Partner-facing web portal for energy companies, inverter manufacturers, and solar monitoring platforms to manage solar installation claims, track payouts, and monitor installations on behalf of their customers. Supports the B2B2C distribution motion.
- SLR to kSLR Migration Portal Web portal for existing SLR holders to migrate their tokens from Energy Web Chain to kSLR on the Base network. Uses Merkle verification for cryptographic proof of balance without exposing user data. Includes rate limiting, multi-signature governance, and on-chain event logging for security.

SolarCoin competitors and assessment
Company assessmentDirect peers
- Power Ledger: Australian blockchain-based peer-to-peer energy trading and renewable energy credit platform. Directly comparable as a blockchain-based incentive/trading layer for distributed solar and renewable energy producers.
- WePower: Blockchain-based renewable energy trading platform that tokenizes power purchase agreements. Closely comparable mechanism to SolarCoin's tokenization of solar production incentives.
Emerging players
- KlimaDAO: Decentralized autonomous organization accumulating carbon credits on-chain via blockchain tokens. Comparable production/output-backed token model, though applied to carbon rather than solar.
- Moss.Earth: Brazilian blockchain platform that tokenizes carbon credits via the MCO2 token. Comparable geographic origin (Brazil), blockchain environmental-asset model, and retail token distribution.
- CarbonX: Canadian carbon credit tokenization platform issuing blockchain-based tokens tied to verified emissions reductions. Comparable production-backed environmental token model.
Broad incumbents
- Energy Web Foundation: Global nonprofit building open-source blockchain solutions for the energy sector. SolarCoin's legacy SLR token was built on Energy Web Chain, making EWF the underlying infrastructure peer and ecosystem collaborator.
- Verra: Operator of the leading carbon credit registry (VCS) and renewable energy certificate standard. Comparable as the incumbent standards body for renewable energy certificates that SolarCoin complements rather than replaces.
- 3Degrees: Established renewable energy certificate and carbon offset broker serving utilities and corporates. Comparable as a mature commercial player in the renewable energy incentive market that SolarCoin disrupts with a tokenized model.
