This study evaluates Sri Lanka’s potential for rooftop solar photovoltaic (PV) installations, especially in regions with limited land availability, to address the country’s energy crisis and reduce reliance on imported fossil fuels. With approximately 115 square kilometers of rooftop area identified across four provinces (Sabaragamuwa, Western, Northern, and North Central), the study estimates a solar PV capacity of about 25 GW, with an annual electricity generation potential of 45 TWh.
Key Findings and Environmental Impact Installing solar PV on these rooftops could reduce carbon emissions by 20 million tons of CO₂ annually, supporting global climate goals and Sri Lanka's energy security. The analysis considers geographic and structural factors, such as shading, rooftop orientation, and PV system efficiency, to accurately estimate feasible solar installation areas.
Supporting a Clean Energy Transition The study advocates for Sri Lanka to implement policies that support rooftop solar adoption, such as incentives, reduced taxes, and subsidies. By leveraging rooftop solar, Sri Lanka can foster a sustainable energy transition, promoting economic stability and environmental protection. The findings provide a framework for maximizing the nation’s solar potential, highlighting how renewable energy can play a pivotal role in addressing energy challenges and promoting self-sufficiency.
