Project Description

9kWp Hybrid Solar System with 11kW Inverter – Batang Ai Remote Base

Deep within the rainforest of Sarawak, the Forestry Department at Batang Ai needed a reliable energy solution. Traditional diesel generators were expensive and noisy, and SEB/SESCO grid access was unfeasible due to cost, terrain, and environmental impact.

Why Grid Power Wasn’t Viable

  • High Cost: Long-distance cabling through rainforest terrain is extremely costly.
  • Unstable Supply: Even urban zones face outages; remote repairs are worse.
  • Slow Approvals: Bureaucratic delays and site feasibility issues.
  • Environmental Risk: Grid expansion could harm protected ecosystems.

The Sunpal Solution

Sunpal engineered a fully off-grid, hybrid solar system to provide clean, reliable, and maintenance-free power.

  • 21 × 430W Bifacial Solar Panels (9.03kWp): High-efficiency dual-sided panels for maximum output.
  • 2 × 5500W Hybrid Inverters (11kW total): Smart load and battery management.
  • 24 × 120Ah Deep Cycle GEL Batteries: Maintenance-free storage for overnight power.
  • Gaya ATS (Auto Transfer Switch): Seamless switching between solar, battery, or generator.
  • Fully Off-grid: No grid dependency, zero utility bills.

Why This Matters

  • Enables 24/7 remote forest monitoring
  • Cuts carbon emissions by replacing diesel
  • Supports mission-critical field equipment
  • Preserves biodiversity with clean energy
