The Process of Rooftop Solar Installation in Sri Lanka
Installing a rooftop solar system in Sri Lanka involves a structured, step-by-step process to ensure efficiency, safety, and long-term performance.
- Site Survey & Feasibility Study: Experts inspect the roof to determine sunlight exposure, structural strength, and available space for solar panels.
- System Design & Proposal: Based on your electricity usage, roof type, and budget, engineers create a tailored solar system design.
- Quotation & Approval: A detailed quotation is provided covering equipment, installation, and warranties. All necessary approvals are obtained from the Ceylon Electricity Board (CEB) or Lanka Electricity Company (LECO).
- Installation & Wiring: Solar panels, inverters, and mounting structures are professionally installed and connected to the home’s electrical system.
- Testing & Commissioning: The system is thoroughly tested, synchronized with the national grid, and certified for safe operation.
