Solar Mesh
Exploring how low-cost embedded sensing and Wi-Fi HaLow can make smaller, off-grid solar installations easier to understand and maintain.
Visibility for decentralized energy.
Many smaller solar installations operate with limited connectivity and limited visibility into panel, battery, and load behavior. Solar Mesh investigates a modular monitoring approach that can be added without replacing an existing charge controller.
The research combines parallel electrical sensing, microcontroller-based acquisition, long-range wireless communication, and a gateway for local or remote monitoring. The work is exploratory: technical objectives and architecture are described here without implying that unreported performance targets have already been demonstrated.
Architecture and prototype investigation. Measured range, energy budget, reliability results, and field validation will be published only after testing and review.
Technical priorities
- Characterize panel, battery, and load measurements using non-intrusive interfaces.
- Evaluate sub-GHz Wi-Fi HaLow links for distributed telemetry.
- Investigate local-first data visibility and offline operation.
- Study monitoring, alerting, and maintenance needs in constrained environments.
Validation questions
How reliable is the network as nodes and conditions vary? What are the power and cost tradeoffs? Which measurements yield actionable information? Those questions guide upcoming test design.
