National Early Warning System

Project overview

In 2026, GoKoval deployed 22 W IoT-grade solar power systems to support remote early warning systems across Timor-Leste. They provide reliable off-grid energy to flood and disaster monitoring sensors operating in high-risk, hard-to-access locations.

The objective is simple: keep data flowing during extreme weather, when early alerts matter most.

The challenge

Many early warning sensors are installed in remote areas without stable grid access. Common issues include:

• Slow battery recovery during cloudy conditions
• Inconsistent power supply
• Poor matching between panel, battery and load
• Limited local maintenance capability

Without reliable energy, early warning data fails — and communities lose critical response time.

Our solution

GoKoval designed and deployed a 22 W IoT-grade solar node optimised for:

• An 18 V system architecture for better morning charge recovery
• A stable battery charging profile
• Resilience in tropical weather
• Low-maintenance operation
• A compact installation footprint

Under typical conditions the system reaches full battery recovery early in the day, leaving a buffer for unpredictable weather.

Impact

• Reliable operation of flood monitoring stations
• Increased uptime of disaster risk sensors
• Less system downtime during the rainy season
