Nageswari, Rangpur Division, Bangladesh, located at latitude 25.9661° and longitude 89.6945° in the Northern Sub Tropics, offers a promising location for solar PV energy generation throughout the year. The seasonal electricity production shows consistent output with some notable variations.

Seasonal Solar Production

Solar panels in Nageswari can generate solid electricity output year-round, with spring being particularly productive at 5.73 kWh per day for each kilowatt of installed capacity. Autumn follows with 4.79 kWh/day, while summer yields 4.74 kWh/day. Winter shows the lowest production at 4.06 kWh/day per kW installed, but still maintains reasonable generation capabilities.

Spring stands out as the optimal season for solar energy production in Nageswari, Rangpur Division, offering nearly 41% more energy than the winter months. This makes March through May an excellent period for maximizing solar returns on investment.

Optimal Panel Installation

For fixed solar panel installations in Nageswari, Rangpur Division, the ideal angle to maximize year-round production is 25 degrees facing South. This tilt angle optimizes the annual solar energy capture by balancing seasonal variations in the sun's position.

Environmental Challenges

Several significant environmental factors could impact solar production in Nageswari:

• Monsoon season (June-September) brings heavy rainfall and increased cloud cover, potentially reducing solar efficiency despite summer's typically strong solar potential.
• Dust and airborne particulates are common in Bangladesh's rural areas, which can accumulate on panels and reduce efficiency by 10-30% if not addressed.
• Flooding is a recurring issue in this low-lying region, which could threaten ground-mounted solar installations.

Preventative Measures

To maximize solar production despite these challenges, several preventative measures are recommended:

• Install panels on elevated structures to protect against seasonal flooding
• Implement automated or regular cleaning systems to remove dust buildup, especially during the dry season
• Use weather-resistant components rated for high humidity environments
• Consider slight over-sizing of the system to compensate for reduced monsoon season production
• Install microinverters or power optimizers to minimize production losses when some panels are shaded or dirty

With these considerations addressed, Nageswari presents a viable location for solar PV installations with good year-round production potential, especially during the spring months when energy generation peaks.

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

Seasonal solar PV output for Latitude: 25.9661, Longitude: 89.6945 (Nageswari, 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 25° South in Nageswari, Bangladesh

To maximize your solar PV system's energy output in Nageswari, Bangladesh (Lat/Long 25.9661, 89.6945) throughout the year, you should tilt your panels at an angle of 25° 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 Nageswari, 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 Nageswari, Bangladesh. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 25° 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	32° 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 Nageswari, 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 Nageswari, 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 Nageswari, Bangladesh

Topography of Nageswari, Bangladesh

Nageswari is situated in the northern part of Bangladesh in the Kurigram District, characterized by a predominantly flat alluvial plain typical of the Brahmaputra River basin. The landscape consists of low-lying floodplains with elevations generally ranging from 10 to 25 meters above sea level. This region forms part of the greater Bengal Basin, one of the largest river deltas in the world. The terrain around Nageswari features a network of rivers, streams, and seasonal water bodies that crisscross the landscape. The Brahmaputra River (locally known as Jamuna) and its tributaries have significantly influenced the topography, creating natural levees, sandbars, and depressions throughout the area. During monsoon seasons, many low-lying areas become temporarily inundated, creating a dynamic landscape that changes subtly from season to season. The soil composition primarily consists of fertile alluvial deposits, ranging from sandy loam to clay loam, deposited by the rivers over centuries. These soils are generally deep and moderately well-drained in higher areas, while lower depressions may have more clayey, poorly drained soils.

Potential Areas for Solar PV Development

The flat terrain around Nageswari presents several advantages for solar photovoltaic development. The most suitable areas for large-scale solar installations would be the slightly elevated lands that remain dry year-round, particularly the natural levees and higher ground that avoid seasonal flooding. The northern and northwestern outskirts of Nageswari offer promising locations for solar development. These areas typically have slightly higher elevation compared to the surrounding floodplains, reducing flood risks that could damage solar infrastructure. The stable, non-waterlogged soils in these locations provide better foundation conditions for mounting structures. Agricultural fallow lands and barren patches scattered throughout the region could also be repurposed for solar installations. These areas often have good drainage characteristics and minimal vegetation that would require clearing. The gently undulating terrain in some parts actually benefits solar deployment, as it reduces the potential for water pooling while requiring minimal land preparation. Areas to avoid would include the numerous low-lying depressions locally known as "beels" or "haors" that become waterlogged during rainy seasons. Similarly, lands directly adjacent to river channels should be excluded due to erosion risks and potential flooding hazards. The southeastern periphery of Nageswari also contains some promising elevated terrains that remain relatively dry throughout the year. These areas offer good solar exposure with minimal shadowing effects from natural features, making them potentially suitable for photovoltaic development. Any large-scale solar development would need to incorporate flood mitigation measures given the region's vulnerability to seasonal inundation, particularly using raised mounting structures and robust foundation systems designed for the local soil conditions.
