Solar PV Analysis of Narsingdi, Bangladesh
The location at Narsingdi, Dhaka Division, Bangladesh is quite good for generating energy through solar panels all year round. The amount of electricity that can be produced from each kilowatt of installed solar power varies slightly with the seasons, but it's always pretty decent.
In Summer, you can expect to get about 4.5 units (kWh) of electricity per day for each kilowatt of solar panels you have installed. In Autumn, this goes up a bit to 4.75 units per day; in Winter it drops slightly to 4.06 units per day; and in Spring it jumps up significantly to almost 6 units per day.
So if you're thinking about when would be the best times of year to generate solar power at this location, Spring would definitely be your top choice because that's when you'd get the most electricity out of your solar panels.
If you're installing fixed panel installations here, tilting them at an angle facing 23 degrees South will give you the maximum total production over the course of a year.
As far as local factors that could potentially affect your ability to produce solar power here - there aren't any major ones that come immediately to mind. However, like anywhere else in the world, things like heavy cloud cover or dust and dirt on your panels could reduce their efficiency somewhat.
To prevent these kind of issues from affecting your energy production too much: make sure your panels are kept clean and clear from obstructions; consider installing some sort of tracking system so they can follow the sun throughout the day; and possibly look into getting some battery storage so any excess power generated during peak times isn't wasted but stored for use later on when conditions might not be as ideal.
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 Narsingdi
Seasonal solar PV output for Latitude: 23.9267, Longitude: 90.7005 (Narsingdi, 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 Narsingdi, Bangladesh
To maximize your solar PV system's energy output in Narsingdi, Bangladesh (Lat/Long 23.9267, 90.7005) 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 Narsingdi, 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 Narsingdi, 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 | 30° 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 Narsingdi, 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 Narsingdi, 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 Narsingdi, Bangladesh
Narsingdi, Bangladesh is located in the eastern part of the country. The topography of this area is characterized by flat plains with small hills and valleys. It lies on the bank of Meghna River, which provides fertile alluvial soil suitable for agriculture. The region experiences a tropical monsoon climate with high humidity and temperatures averaging between 26-29 degrees Celsius.
For large-scale solar PV installations, areas that are flat and open would be most suitable to allow maximum exposure to sunlight. In Narsingdi's case, non-arable lands or fallow agricultural lands could be potential sites for such installations as they typically have less obstructions like trees or buildings that can cast shadows on the panels.
Moreover, regions closer to the equator receive more sunlight throughout the year making them ideal for solar power generation. Given Narsingdi's latitude (23.9267), it falls into this category making it a good candidate for solar energy production.
However, factors other than topography also need to be considered when planning large scale solar PV projects such as local weather patterns (cloud cover, rainfall etc.), availability of infrastructure for power transmission and storage, environmental impact assessments among others.
It would require detailed site surveys and feasibility studies conducted by professionals in renewable energy sector to identify specific locations around Narsingdi best suited for large-scale solar PV installations.
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.
