Solar Potential & Climate Data for Jakarta
Solar Overview
At -6.21° latitude, Jakarta receives 1,609 annual sun hours, peaking in September. Located in the tropics at -6.21° latitude, Jakarta offers remarkably stable solar conditions across all seasons. Jakarta presents challenging conditions for solar energy, though hybrid systems and careful planning can still yield viable results.
Geographic Impact
Positioned at -6.2088° latitude and 106.8456° longitude, Jakarta's geographic coordinates shape its solar resource profile. The equatorial latitude creates optimal conditions for solar power, with high sun angles and balanced day lengths year-round eliminating seasonal production concerns.
Rating Methodology
With 1,609 sun hours annually and 28.9°C average temperature, Jakarta achieves a "Poor" solar potential rating. Warm conditions may decrease peak efficiency by 5-10%, though overall production remains strong due to high irradiation levels. Solar installations in Jakarta typically achieve capacity factors of 10-12%, requiring careful economic evaluation and optimal system design.
Understanding the Data
The accompanying chart illustrates monthly solar irradiation patterns for Jakarta. Monthly distribution is fairly uniform, with September as the highest-production month. This pattern influences both the technical design and economic viability of solar energy systems in Jakarta.
💡 Recommendation: Adequate ventilation beneath panels helps maintain efficiency during warm weather periods.
