OneWattSolar

OneWattSolar is a blockchain-powered energy-as-a-service (EaaS) platform for residential and commercial customers who need off-grid rooftop solar with zero upfront system cost.

Key capabilities include:

• Zero-upfront solar deployment: the company installs, operates, and maintains rooftop systems without requiring customers to buy the infrastructure upfront.
• Pay-as-you-go electricity billing: customers pay for energy use at $0.10 per kWh, using tokenized payments (“green coins”) on Ethereum; onboarding includes a refundable security deposit.
• IoT monitoring and remote control: smart metering and connected hardware support real-time performance visibility, automated alerts for support teams, and remote connect or disconnect based on account status.
• Tariff and account management: supports fixed or dynamic pricing and integrates mobile money for payment processing and customer account access.

Available on Web.

Designed for individuals and businesses in energy-poor regions, as well as ecosystem partners such as solar companies, installers, investors, and franchisees.

Notable in the African market context for combining off-grid solar operations with transparent digital payments and remote system management, and for its stated deployment history of 50 megawatts installed since its 2019 launch, targeting Nigeria first with broader sub-Saharan Africa expansion.
