Solar PV Analysis of Thakurgaon, Bangladesh
Thakurgaon, Rangpur Division, Bangladesh, located in the Northern Sub Tropics at coordinates 25.8513, 88.3671, presents a generally favorable environment for solar PV energy generation throughout the year. The location's potential for solar energy production varies across seasons, with some periods being more productive than others.
Seasonal Solar Output
Spring emerges as the most productive season, with an impressive output of 5.76 kWh per day for each kW of installed solar capacity. Summer and autumn follow closely, generating 4.62 kWh/day and 4.66 kWh/day respectively. Winter sees a slight dip in production, yielding 3.89 kWh/day, but still maintains a respectable output.
The ideal times for solar energy generation at this location are during spring and the transitional months between seasons. The longer daylight hours and clearer skies during these periods contribute to increased solar panel efficiency and higher energy output.
Optimal Panel Tilt
For fixed panel installations in Thakurgaon, Rangpur Division, the ideal tilt angle to maximize year-round solar production is 24 degrees facing South. This angle has been calculated taking into account the location's latitude, daily solar elevation angles, and weighted by NASA's solar irradiance data.
Environmental Considerations
While Thakurgaon offers good potential for solar energy production, there are some environmental factors to consider:
- Monsoon season: Heavy rainfall and increased cloud cover during the monsoon months (June to September) may temporarily reduce solar panel efficiency.
- Dust and pollution: Agricultural activities and occasional dust storms can deposit particles on solar panels, potentially decreasing their performance.
Preventative Measures
To mitigate these environmental challenges and ensure optimal energy production, consider implementing the following measures:
- Install a reliable cleaning system or schedule regular manual cleaning to remove dust and debris from the panels.
- Use high-quality, weather-resistant solar panels that can withstand heavy rainfall and humidity.
- Implement a slight increase in panel tilt during the monsoon season to aid in natural cleaning by rainwater.
- Consider adding a backup energy storage system to compensate for reduced output during periods of heavy cloud cover.
By taking these precautions, solar PV installations in Thakurgaon can maximize their energy production potential and provide a reliable source of renewable energy throughout the year.
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 Thakurgaon
Seasonal solar PV output for Latitude: 25.8513, Longitude: 88.3671 (Thakurgaon, 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 24° South in Thakurgaon, Bangladesh
To maximize your solar PV system's energy output in Thakurgaon, Bangladesh (Lat/Long 25.8513, 88.3671) throughout the year, you should tilt your panels at an angle of 24° 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 Thakurgaon, 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 Thakurgaon, Bangladesh. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 24° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 10° South in Summer | 31° South in Autumn | 41° South in Winter | 20° 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 Thakurgaon, 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 Thakurgaon, 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 Thakurgaon, Bangladesh
The topography around Thakurgaon, Bangladesh, is characterized by relatively flat terrain typical of the Bengal Plain. This area is part of the larger Indo-Gangetic Plain, which is known for its low-lying, level landscape. The region around Thakurgaon consists primarily of alluvial plains formed by sediment deposits from rivers over thousands of years.
The land in and around Thakurgaon is generally very flat with minimal elevation changes. There are no significant hills or mountains in the immediate vicinity. The average elevation of the area is approximately 40 to 50 meters above sea level, with only slight variations across the landscape. This flat terrain is interrupted by numerous rivers, streams, and seasonal water bodies that crisscross the region.
The soil in this area is predominantly fertile alluvium, which is excellent for agriculture. As a result, much of the land is used for farming, with rice being a major crop. The landscape is dotted with small villages, agricultural fields, and patches of vegetation, including some scattered trees and shrubs.
Regarding areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, several factors make the region around Thakurgaon potentially favorable:
1. The flat terrain is ideal for solar farms, as it minimizes the need for extensive land preparation and allows for easy installation of solar panels.
2. The region receives ample sunlight throughout the year, which is crucial for solar energy generation.
3. Areas of fallow or less productive agricultural land could be repurposed for solar installations without significantly impacting food production.
Specifically, areas to the north and west of Thakurgaon town might be particularly suitable for large-scale solar PV projects. These areas tend to have slightly higher elevations and are less prone to flooding compared to regions closer to major rivers. Additionally, land parcels that are not currently used for intensive agriculture or are at a safe distance from densely populated areas would be preferable.
However, it's important to note that any large-scale solar project would need to consider factors such as proximity to the electrical grid, local land use regulations, and potential environmental impacts. A detailed site-specific assessment would be necessary to determine the most suitable locations for solar PV installations in the region.
