Bogra, Rajshahi Division, Bangladesh, situated at 24.813°N, 89.3152°E in the Northern Sub Tropics, presents a favorable location for solar PV energy generation throughout the year. The seasonal electricity output per kW of installed solar varies, with Spring offering the highest production at 5.82 kWh/day, followed closely by Autumn and Summer at 4.82 and 4.81 kWh/day, respectively. Winter sees a slight dip in production, yielding 4.01 kWh/day.

Seasonal Performance

Spring emerges as the prime season for solar energy generation in Bogra, Rajshahi Division, with longer daylight hours and clearer skies contributing to peak performance. Summer and Autumn maintain strong outputs, benefiting from the region's subtropical climate. While Winter experiences a minor decrease in production, it still maintains a respectable output, ensuring year-round viability for solar PV systems.

Optimal Panel Orientation

For fixed panel installations in Bogra, Rajshahi Division, the ideal tilt angle to maximize year-round solar production is 23 degrees facing South. This orientation allows panels to capture optimal sunlight throughout the year, accounting for the location's latitude and the Earth's elliptical orbit.

Environmental Considerations

While Bogra's climate is generally conducive to 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 output.
• Dust and pollution: The region's agricultural activities and urban development can lead to airborne particulates, potentially affecting panel efficiency.

Preventative Measures

To mitigate these challenges and ensure optimal energy production, several preventative measures can be implemented during solar installation:

1. Install panels at the recommended 23-degree tilt to maximize exposure and facilitate natural cleaning by rainwater.

2. Implement a regular cleaning schedule, especially during drier periods, to remove dust and debris from panel surfaces.

3. Consider using anti-soiling coatings on panels to reduce dust accumulation and improve self-cleaning properties.

4. Install a robust mounting system capable of withstanding strong winds during monsoon seasons.

5. Utilize high-quality, weather-resistant components designed to perform well in humid subtropical climates.

By addressing these factors, solar PV installations in Bogra can maintain high efficiency and productivity throughout the year, capitalizing on the location's overall favorable conditions for solar energy generation.

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 Bogra

Seasonal solar PV output for Latitude: 24.813, Longitude: 89.3152 (Bogra, 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 Bogra, Bangladesh

To maximize your solar PV system's energy output in Bogra, Bangladesh (Lat/Long 24.813, 89.3152) 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 Bogra, 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 Bogra, 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 Bogra, 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 Bogra, Bangladesh.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Bogra, Bangladesh

Bogra, located in northern Bangladesh, sits in a region characterized by its relatively flat terrain. The area surrounding Bogra is part of the vast alluvial plain formed by the Ganges and Brahmaputra rivers and their tributaries. This landscape is predominantly composed of fertile lowlands, with occasional gentle undulations and small hillocks breaking up the otherwise level topography. The immediate vicinity of Bogra features expansive agricultural fields, interspersed with numerous rivers and streams that crisscross the region. These waterways, including the Karatoya River which flows near the city, have played a significant role in shaping the local landscape over time. The soil in this area is primarily composed of rich alluvial deposits, making it highly suitable for agriculture.

Potential for Solar PV Development

When considering areas nearby Bogra for large-scale solar PV installations, several factors come into play. The flat terrain of the region offers a distinct advantage for solar development, as it minimizes the need for extensive land preparation and allows for efficient layout of solar panels. The areas to the north and west of Bogra present particularly promising locations for solar PV projects. These regions tend to have slightly higher elevations and experience less frequent flooding compared to the lower-lying areas to the south and east. The elevated grounds provide better protection for solar infrastructure against potential water damage during the monsoon season. Additionally, the agricultural lands surrounding Bogra could be suitable for solar development, especially in areas where crop yields may be lower or where farmers are looking for alternative land uses. However, it's crucial to balance solar development with food production needs, considering the region's agricultural importance. It's worth noting that while the flat terrain is advantageous, care must be taken to avoid areas prone to flooding or erosion, particularly those close to rivers or in low-lying flood plains. Ideal sites would be on slightly elevated ground, away from major water bodies, and with good access to existing power infrastructure for easy grid connection. In conclusion, the relatively flat topography around Bogra offers good potential for large-scale solar PV development, with areas to the north and west being particularly suitable due to their slightly higher elevation and reduced flood risk. However, careful site selection and environmental impact assessments would be necessary to ensure the sustainability and effectiveness of any large-scale solar projects in this region.
