Solar Energy Potential in Chapai Nawabganj, Rajshahi Division, Bangladesh
Chapai Nawabganj, Rajshahi Division, located in the Northern Sub Tropics of Bangladesh, offers a promising location for solar energy generation throughout the year. The city's geographical position at 24.5985°N latitude and 88.2896°E longitude provides favorable conditions for harnessing solar power.Seasonal Solar Output
The solar energy potential in Chapai Nawabganj varies across seasons, with spring being the most productive period. During spring, solar panels can generate an impressive 5.82 kWh per day for each kilowatt of installed capacity. Summer follows closely with 4.71 kWh/day, while autumn produces 4.49 kWh/day. Winter sees a slight dip in production, with 3.84 kWh/day, but still maintains a respectable output.Optimal Panel Tilt
For fixed solar panel installations in Chapai Nawabganj, Rajshahi Division, the ideal tilt angle to maximize year-round energy production is 23 degrees facing south. This angle ensures optimal exposure to sunlight throughout the year, taking into account the city's latitude and the Earth's elliptical orbit.Environmental Factors and Preventative Measures
While Chapai Nawabganj generally offers favorable conditions for solar energy production, there are some environmental factors to consider: 1. Monsoon season: Bangladesh experiences heavy rainfall during the monsoon months (June to September), which can temporarily reduce solar output. To mitigate this, consider installing panels with good water-resistant properties and ensuring proper drainage systems are in place. 2. Dust and pollution: The region may experience periods of increased dust and air pollution, which can accumulate on solar panels and reduce efficiency. Regular cleaning and maintenance of panels can help maintain optimal performance. 3. High temperatures: During summer months, extreme heat can slightly decrease panel efficiency. Choosing high-quality panels with good heat tolerance and ensuring proper ventilation during installation can help minimize this impact. By addressing these factors during the planning and installation phases, solar energy systems in Chapai Nawabganj can achieve consistent and reliable performance 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 Chapai Nawabganj
Seasonal solar PV output for Latitude: 24.5985, Longitude: 88.2896 (Chapai Nawabganj, 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 Chapai Nawabganj, Bangladesh
To maximize your solar PV system's energy output in Chapai Nawabganj, Bangladesh (Lat/Long 24.5985, 88.2896) 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 Chapai Nawabganj, 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 Chapai Nawabganj, 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 |
|---|---|---|---|
| 9° South in Summer | 30° South in Autumn | 40° South in Winter | 18° 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 Chapai Nawabganj, 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 Chapai Nawabganj, 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 Chapai Nawabganj, Bangladesh
The topography around Chapai Nawabganj, Bangladesh, is primarily characterized by flat, low-lying plains. This area is part of the larger Bengal Basin, which is known for its extensive floodplains and delta systems. The landscape is shaped by the Ganges River and its tributaries, which have deposited rich alluvial soil over millennia.
The terrain in and around Chapai Nawabganj is generally very flat, with minimal elevation changes. The average elevation is only a few meters above sea level, typically ranging from 15 to 25 meters. This flatness extends for many kilometers in all directions, creating a vast, open landscape that is primarily used for agriculture, particularly rice cultivation.
While there are no significant hills or mountains in the immediate vicinity, the region does feature some subtle topographical features. These include slight undulations in the land, natural levees along river banks, and occasional depressions that may form seasonal wetlands during the monsoon season.
Suitability for Large-Scale Solar PV
When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The flat terrain of the region is generally favorable for solar PV, as it minimizes shading issues and simplifies construction. However, other considerations are also important:
1. Agricultural land: Much of the area is used for farming, which may create conflicts with solar development. Ideally, solar installations should be placed on less productive or fallow land to minimize impact on food production.
2. Flood-prone areas: Low-lying areas near rivers that are prone to flooding should be avoided. Solar installations are best placed on slightly elevated ground to reduce the risk of water damage.
3. Accessibility: Areas with good road access would be preferable for the transportation of equipment and maintenance purposes.
4. Grid connectivity: Proximity to existing electrical infrastructure is important for connecting large-scale solar projects to the power grid.
Given these factors, the most suitable areas for large-scale solar PV near Chapai Nawabganj would likely be slightly elevated lands that are not prime agricultural areas, located away from flood-prone zones but close to existing roads and power infrastructure. Such areas might be found on the outskirts of urban areas or in less fertile regions that are not intensively farmed. A detailed land use and topographical survey would be necessary to identify specific optimal locations.
