Solar PV Analysis of Burichang, Bangladesh
Burichang, Chittagong, Bangladesh, located in the Northern Sub Tropics, offers a promising location for solar energy generation. The area experiences consistent solar radiation throughout the year, making it suitable for photovoltaic (PV) installations.
Seasonal Solar Performance
Solar energy production in Burichang varies across seasons, with spring being the most productive period. During spring, solar panels can generate an impressive 6.16 kWh per day for each kilowatt of installed capacity. Summer and winter show similar outputs at 4.69 kWh/day and 4.70 kWh/day, respectively. Autumn performance is slightly better, yielding 5.11 kWh/day.
These figures indicate that Burichang maintains a relatively stable solar energy production throughout the year, with a notable peak in spring. This consistency makes it an ideal location for year-round solar energy generation, with spring being the optimal season for maximum output.
Optimal Panel Tilt
For fixed solar panel installations in Burichang, Chittagong, the ideal tilt angle to maximize year-round energy production is 23 degrees facing South. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's specific latitude.
Environmental Considerations
While Burichang presents favorable conditions for solar energy production, there are some environmental factors to consider:
- Monsoon season: Bangladesh experiences heavy rainfall during the monsoon months, which could temporarily reduce solar output.
- Dust and pollution: The region may be prone to dust and air pollution, which can accumulate on solar panels and decrease efficiency.
To mitigate these issues, regular cleaning and maintenance of solar panels is essential. Installing panels at the optimal tilt angle can also help with natural cleaning during rainfall. Additionally, using high-quality, weather-resistant panels and implementing proper drainage systems can enhance the longevity and efficiency of the solar installation.
Overall, Burichang's location offers a favorable environment for solar PV systems, with consistent year-round production and a notable peak in spring. By addressing potential environmental challenges through proper installation and maintenance practices, solar energy can be a reliable and efficient power source in this region.
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 88 locations across Bangladesh. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Burichang
Seasonal solar PV output for Latitude: 23.549, Longitude: 91.1327 (Burichang, Bangladesh), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
Ideally tilt fixed solar panels 23° South in Burichang, Bangladesh
To maximize your solar PV system's energy output in Burichang, Bangladesh (Lat/Long 23.549, 91.1327) throughout the year, you should tilt your panels at an angle of 23° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Burichang, Bangladesh
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Burichang, Bangladesh. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 23° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 8° South in Summer | 29° South in Autumn | 39° South in Winter | 17° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Burichang, Bangladesh
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Burichang, Bangladesh.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Burichang, Bangladesh
The topography around Burichang, Bangladesh, is characterized by relatively flat lowlands typical of the country's central and eastern regions. This area is part of the larger Bengal Plain, which is formed by the alluvial deposits of major rivers like the Ganges and Brahmaputra. The landscape consists primarily of fertile floodplains and deltaic terrain, with occasional small hills or elevated areas.
In the immediate vicinity of Burichang, you'll find a mix of agricultural fields, scattered settlements, and numerous small water bodies such as ponds and canals. The terrain is generally low-lying, with elevations typically ranging from just a few meters above sea level to around 20-30 meters in slightly higher areas. This flat topography is interrupted by gentle undulations and minor variations in elevation, but there are no significant mountains or steep hills in the immediate area.
Regarding areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, several factors need to be considered. The ideal locations would be:
- Open, flat land: Areas with minimal vegetation and obstacles, such as fallow agricultural fields or unused plots, would be preferable. These are relatively common in the region surrounding Burichang.
- Higher ground: While the area is generally flat, slightly elevated locations that are less prone to flooding would be more suitable. This helps protect the solar infrastructure from potential water damage during monsoon seasons.
- Away from settlements: Locations that are not immediately adjacent to densely populated areas would be ideal to minimize land-use conflicts and potential shading issues.
- Accessible areas: Sites with good road connectivity for construction and maintenance purposes would be advantageous.
Given these criteria, the most suitable areas for large-scale solar PV installations near Burichang would likely be found in the rural outskirts of the town, where there are expansive agricultural lands and less densely populated areas. Specific locations to the north or east of Burichang might offer slightly higher elevations and could be worth investigating. However, a detailed on-site survey would be necessary to identify the most optimal locations, taking into account local land ownership, soil conditions, and proximity to the electrical grid.
