Sourceful Energy

Sourceful Energy is a decentralized physical infrastructure network (DePIN) project built on Solana that aggregates privately owned distributed energy resources (DERs) — solar inverters, battery storage, smart meters, and electric vehicles — into a community-run virtual power plant (VPP). Participants connect their hardware to the Sourceful Energy Network through the Energy Gateway device, earn SRC tokens for verified renewable energy production, and can earn additional rewards for contributing dispatchable capacity to grid stabilization services. The project is headquartered in Kalmar, Sweden and was founded in 2022.

Core Mechanism

The foundational problem Sourceful addresses is the same one facing most rooftop solar and battery owners: hardware sits largely idle as a passive asset, disconnected from the broader grid optimization layer. Sourceful's approach is to turn those scattered assets into coordinated grid infrastructure by pooling them into a virtual power plant governed by token incentives on Solana.

The network relies on two core verification mechanisms:

Proof-of-Source authenticates that a connected device is genuinely generating or storing renewable energy. When an inverter is linked to the Energy Gateway, the gateway attests the plant's digital identity to the Solana blockchain, enabling the network to issue rewards based on verified production data rather than self-reported claims.

Proof-of-Control extends the model beyond passive monitoring into active grid services. It allows the network to briefly dispatch connected resources — throttling or releasing stored energy from batteries, for example — to help balance supply and demand on the grid. Participants who opt in receive additional compensation for making their assets dispatchable.

Together these two mechanisms enable Sourceful to offer what centralized utilities have historically provided through large-scale power plants: reliable, flexible generation capacity. The difference is that Sourceful's capacity is owned and operated by the network's participants rather than a single corporate entity.

Energy Gateway

The Energy Gateway is the physical bridge between a participant's DERs and the Sourceful network. It connects compatible solar inverters and battery storage systems to the internet and relays production data to the Solana blockchain. The device has been sold through hardware distributors including RAKwireless (listed at $149 USD) and was distributed through a beta program for early adopters. The Gateway supports multiple regional power adapter standards (European, American, UK, and Australian), reflecting the project's ambition for cross-market deployment.

Compatible hardware includes a range of solar inverters and battery storage systems listed in the project's documentation. Users manage their connected devices and track earnings through the Sourceful mobile app (available on Android, with iOS support planned) or a desktop interface.

SRC Token

SRC is Sourceful's native utility token, issued on the Solana blockchain. The maximum supply is 250 billion SRC tokens. During the beta phase, participants have been accumulating "Sourceful Rewards" — points that will convert to SRC upon the token's public launch. The tokenomics design draws on the model pioneered by Helium, including a token-burning mechanism that activates when energy services are sold on the network. This burn-on-service-sale structure is intended to create demand pressure on the token as network utilization grows.

Solana was selected as the base layer for its transaction throughput, low fees, and active DePIN ecosystem. To receive SRC rewards, participants need a compatible Solana wallet.

Key Products and Features

• Energy Gateway hardware: Physical device connecting DERs to the Sourceful network via compatible inverters and storage systems
• Sourceful App (v2.2.0 as of April 2026): Mobile and web dashboard with savings tracker, spot price visibility, V2X charger controls, solar production forecasting, and reward tracking
• Zap white-label platform: A real-time meter and energy insight app for utility customers; launched February 2026 in partnership with Swedish utility Kalmar Energi ahead of demand-based grid tariff reforms
• Battery Optimizer: A 24-hour-ahead planning algorithm that optimizes dispatch decisions across connected battery assets, with transparent decision logging

Partnerships and Integrations

Sourceful has established two notable integrations that expand its network reach. The collaboration with Arkreen — a solar data network on EVM-compatible chains — enables Sourceful's connected solar devices to issue tokenized Renewable Energy Certificates (RECs) on-chain through the Arkreen network. This dual-reward structure lets Srcful participants earn from both ecosystems simultaneously, and opens a pathway for solar energy data to be monetized as verifiable blockchain assets.

Sourceful has also explored integration with Helium's IoT miner network, which would allow Helium hotspot operators to participate in VPP coordination and receive token rewards for managing energy sources — broadening the operator base beyond direct DER owners.

Team and Funding

Sourceful Energy was founded in 2022 and is based in Kalmar, Sweden. The company has raised $3.77 million from investors including Eviny Ventures, Kosmos Ventures, Paper Ventures, Variant, and Borderless Capital. The team operates with a presence in both the traditional energy sector (working with utilities like Kalmar Energi) and the DePIN/Web3 ecosystem, bridging grid infrastructure expertise with blockchain-native incentive design.

Fit in the Solana Ecosystem

Sourceful sits at the intersection of two of Solana's most active growth verticals: DePIN and real-world assets. The project represents a direct application of DePIN incentive logic to physical energy infrastructure — a sector where decentralized coordination has tangible grid-scale consequences. By issuing rewards on Solana for real-world energy production and grid services, Sourceful contributes to the case that on-chain token incentives can coordinate physical infrastructure at scale, not just digital services. Its cross-chain REC partnership with Arkreen also positions it as a data source layer for broader sustainable finance applications, where verified on-chain proof of green energy production has potential value far beyond the SRC token itself.
