Trishal, Mymensingh Division, Bangladesh, located in the Northern Sub Tropics at coordinates 24.5814, 90.3922, offers a promising location for solar PV energy generation throughout the year. The seasonal variations in electricity output per kW of installed solar provide valuable insights into the potential for solar energy production in this area.

Seasonal Solar Performance

Spring emerges as the most productive season, with an impressive output of 5.79 kWh/day per kW installed. This is followed by autumn, which generates 4.80 kWh/day. Summer yields 4.37 kWh/day, while winter sees a slight dip to 3.92 kWh/day. These figures indicate that Trishal maintains a relatively consistent solar energy potential throughout the year, with spring and autumn being particularly favorable for solar power generation.

Optimal Panel Tilt

For fixed panel installations in Trishal, Mymensingh Division, the ideal angle to maximize year-round solar PV production is 23 degrees South. This tilt angle takes into account the location's latitude and the Earth's elliptical orbit, ensuring optimal exposure to sunlight throughout the year.

Environmental Considerations

While Trishal generally offers favorable conditions for solar energy production, there are some environmental factors to consider:

• Monsoon season: Heavy rainfall and increased cloud cover during the monsoon months (typically June to September) may temporarily reduce solar panel efficiency.
• Dust and pollution: The region's agricultural activities and urban development can lead to airborne particles that may accumulate on solar panels, potentially decreasing their performance.

Preventative Measures

To mitigate these environmental challenges and ensure optimal solar energy production, consider implementing the following measures:

1. Install a reliable cleaning system or schedule regular manual cleaning to remove dust and debris from the panels.

2. Use high-quality, weather-resistant solar panels that can withstand heavy rainfall and humidity during the monsoon season.

3. Implement a slight increase in panel tilt during the monsoon months to facilitate natural cleaning by rainwater.

4. Consider using microinverters or power optimizers to minimize the impact of partial shading caused by cloud cover.

By addressing these factors, solar installations in Trishal can maximize their energy production potential and take full advantage of the location's favorable solar conditions throughout the year.

Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

Solar output per kW of installed solar PV by season in Trishal

Seasonal solar PV output for Latitude: 24.5814, Longitude: 90.3922 (Trishal, 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 Trishal, Bangladesh

To maximize your solar PV system's energy output in Trishal, Bangladesh (Lat/Long 24.5814, 90.3922) 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 Trishal, 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 Trishal, 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 Trishal, 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 Trishal, 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 Trishal, Bangladesh

The topography around Trishal, Bangladesh, is characterized by its location in the low-lying floodplains of the Brahmaputra River system. This area is part of the larger Bengal Basin, a vast alluvial plain that covers much of Bangladesh and parts of neighboring India. The landscape is predominantly flat, with very gentle slopes and minimal elevation changes across the region. The terrain surrounding Trishal is mainly composed of fertile alluvial soils deposited over centuries by the numerous rivers and streams that crisscross the area. These waterways, including the Old Brahmaputra River, have shaped the land into a network of natural levees, shallow depressions, and occasional small hillocks. During the monsoon season, many low-lying areas become temporarily inundated, creating a dynamic landscape that shifts between land and water. Vegetation in the region is lush and diverse, with a mix of agricultural lands, scattered woodlands, and wetland areas. Rice paddies, jute fields, and other crops dominate much of the landscape, interspersed with patches of tropical and subtropical vegetation. The flat terrain and abundant water resources have made this area highly suitable for agriculture, which remains the primary land use.

Solar PV Potential in the Region

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The flat terrain around Trishal offers advantages for solar development, as it minimizes the need for extensive land preparation and allows for efficient layout of solar panels. Areas slightly elevated above the flood-prone zones would be ideal candidates for solar PV projects. These locations would be less susceptible to seasonal flooding, reducing the risk of damage to equipment and ensuring consistent energy production throughout the year. Fallow agricultural lands or areas with poor soil quality that are not suitable for crop production could be repurposed for solar farms, minimizing the impact on food production. Regions to the north and west of Trishal, where the land gradually rises towards the Madhupur Tract, might offer suitable locations for solar installations. These areas are generally less prone to flooding and could provide stable ground for large-scale solar projects. Additionally, lands near existing power infrastructure or close to major roads would be advantageous, facilitating easier grid connection and maintenance access. It's important to note that while the region has good solar potential due to its tropical latitude, careful site selection is crucial to address challenges such as potential flooding, land-use conflicts, and environmental considerations. Comprehensive environmental and social impact assessments would be necessary to ensure that large-scale solar PV projects are implemented sustainably and in harmony with the local ecosystem and communities.
