Solar PV Analysis of Barguna, Bangladesh
Located at latitude 22.3135 and longitude 90.1031, Barguna, Barisal Division, Bangladesh is a favorable location for the installation of solar photovoltaic (PV) systems. Throughout the year, this city sees an average daily production of 4.25 kWh per kW of installed solar capacity in summer, 4.73 kWh in autumn, 4.32 kWh in winter and an impressive peak of 6.05 kWh during spring.
Barguna's positioning within the Tropics ensures consistent sunlight exposure throughout most parts of the year due to its relatively stable day length and sun path compared to regions further from the equator. This consistent sunlight availability makes it suitable for year-round solar energy generation.
The optimal tilt angle for fixed panel installations at this location is towards the south at a pitch of approximately 22 degrees to maximize sun exposure throughout all seasons.
However, it's important to consider any potential local factors that could affect solar energy production significantly when planning an installation here.
Although no specific weather conditions are known to impede power generation via solar PV directly at this location currently mentioned, it would be prudent to understand that Bangladesh as a whole experiences heavy monsoon rains which can potentially reduce sunlight exposure temporarily during these periods or damage inadequately protected equipment over time if not properly accounted for during design and installation stages.
To ensure greater energy production despite these challenges, measures such as robust weatherproofing techniques should be used on equipment installations along with regular maintenance checks especially post-monsoon season can help mitigate any potential impact on performance due to environmental factors like heavy rainfall or even possible debris accumulation on panels after such events.
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.
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 Barguna
Seasonal solar PV output for Latitude: 22.3135, Longitude: 90.1031 (Barguna, 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 22° South in Barguna, Bangladesh
To maximize your solar PV system's energy output in Barguna, Bangladesh (Lat/Long 22.3135, 90.1031) throughout the year, you should tilt your panels at an angle of 22° 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 Barguna, 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 Barguna, Bangladesh. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 22° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 7° South in Summer | 28° South in Autumn | 38° South in Winter | 16° 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 Barguna, 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 Barguna, 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 Barguna, Bangladesh
The topography around Barguna, Bangladesh is generally flat and low-lying. Areas that are most suited to large scale solar PV would be open, flat areas with good access to sunlight. The nearby coastal areas of the district such as Patharghata, Taltali, Amtali and Bamna Upazilas would likely provide the best sites for large-scale solar PV installations due to their proximity to the sea and relatively flat terrain. Additionally, some of the more hilly areas in the interior of the district may also have potential for solar PV installations if they have adequate access to sunlight.
Bangladesh solar PV Stats as a country
Bangladesh ranks 63rd in the world for cumulative solar PV capacity, with 329 total MW's of solar PV installed. Each year Bangladesh is generating 2 Watts from solar PV per capita (Bangladesh ranks 87th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Bangladesh?
Yes, there are incentives for businesses wanting to install solar energy in Bangladesh. The government of Bangladesh has implemented a number of policies and programs to promote the use of renewable energy sources such as solar power. These include tax exemptions, subsidies, and other financial incentives for businesses that install solar systems. Additionally, the government has set up a Renewable Energy Fund which provides grants to support research and development activities related to renewable energy technologies.
