Evaluating Solar Energy in Singapore, Singapore
Solar Overview
The photovoltaic potential in Singapore is based on 2,029 annual sun hours, concentrated in March. Positioned at 1.35° latitude, Singapore experiences virtually uniform solar production across all months. Singapore presents workable conditions for solar energy, particularly when combined with energy efficiency measures and available incentives.
Geographic Impact
The coordinates 1.3521°N, 103.8198°E define Singapore's position and directly influence its solar energy characteristics. The tropical latitude provides exceptional solar geometry with virtually no seasonal variation, allowing for optimized flat or low-angle panel installations.
Rating Methodology
The "Average" classification reflects Singapore's solar resource quality, considering its 2,029 annual sun hours and 28.3°C average ambient temperature. Temperature-related efficiency reductions are typical for this climate but don't significantly impact the strong economic case for solar energy. These conditions make solar economically viable, especially when electricity costs are high or incentives reduce initial investment.
Understanding the Data
The visualization below presents the annual cycle of sun hours in Singapore. Solar output is well-distributed across all seasons, reaching its maximum during March. This seasonal pattern is typical for locations at this latitude and influences the sizing and economics of solar installations.
💡 Recommendation: Adequate ventilation beneath panels helps maintain efficiency during warm weather periods.
