Dhaka Solar Irradiation: Annual Analysis & Insights
Solar Overview
The solar resource in Dhaka provides around 1,869 annual sun hours, with optimal conditions during March. Located at 23.81°, Dhaka enjoys stable solar production with seasonal variation typically under 15%. Overall, Dhaka is considered moderately suitable for residential and commercial solar installations.
Geographic Impact
The coordinates 23.8103°N, 90.4125°E define Dhaka's position and directly influence its solar energy characteristics. The subtropical position creates exceptional conditions for solar energy, with high sun angles ensuring strong production even during winter months.
Rating Methodology
The "Average" classification reflects Dhaka's solar resource quality, considering its 1,869 annual sun hours and 26.9°C average ambient temperature. Warm conditions may decrease peak efficiency by 5-10%, though overall production remains strong due to high irradiation levels. These conditions make solar economically viable, especially when electricity costs are high or incentives reduce initial investment.
Understanding the Data
The chart displays monthly solar energy availability throughout the year in Dhaka. Monthly distribution is fairly uniform, with March as the highest-production month. This pattern influences both the technical design and economic viability of solar energy systems in Dhaka.
💡 Recommendation: Adequate ventilation beneath panels helps maintain efficiency during warm weather periods.
