Rubicon Tech Stack

End-to-end solar, energy storage, and EV charging solutions for southern Africa

Renewable Energy Equipment Manufacturing Cape Town, Western Cape 201–500 employees Founded 1986 Privately Held

Rubicon designs and deploys integrated renewable energy systems—solar, battery storage, EV charging, and smart energy management—across southern Africa. The tech stack (Go, Python, InfluxDB, Modbus, MQTT) shows a company building custom hardware integrations and real-time energy monitoring, not just reselling commodity equipment. Active hiring across sales, engineering, and support, plus pains around scaling team capacity and energy modelling, suggests Rubicon is transitioning from project-led delivery toward repeatable products and faster deployment cycles.

About Rubicon

Rubicon is a Cape Town-based renewable energy systems integrator serving mid-market and enterprise customers across southern Africa and into Spain. The company provides end-to-end services: system design (using AutoCAD, DIALux, Revit), supply of hardware from local and global vendors, software integration, and on-site implementation. Their portfolio spans high-efficiency lighting, grid-tied and off-grid solar plants, battery energy storage systems, smart energy management platforms, industrial backup power, and EV charging infrastructure. Revenue and delivery are driven by tender response, site assessments, and long-form engineering contracts rather than SaaS licensing—a capital-intensive, margin-sensitive model that requires deep technical expertise and reliable project execution.
