Evaluating Solar Energy in Manila, Philippines
Solar Overview
The photovoltaic potential in Manila is based on 1,908 annual sun hours, concentrated in April. Positioned at 14.60° latitude, Manila experiences virtually uniform solar production across all months. Manila presents workable conditions for solar energy, particularly when combined with energy efficiency measures and available incentives.
Geographic Impact
The specific coordinates of 14.5995°N, 120.9842°E establish Manila's unique solar energy potential. 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" solar potential rating for Manila is based on multiple factors including annual sun hours (1,908), average temperature (28.8°C), and seasonal variability. Temperature-related efficiency reductions are typical for this climate but don't significantly impact the strong economic case for solar energy. The moderate solar resource supports payback periods of 10-15 years for residential systems, particularly when incentives are available.
Understanding the Data
