Sherpur, Rajshahi Division, Bangladesh offers reasonably good conditions for solar energy generation throughout most of the year. Located in the Northern Sub Tropics at coordinates 24.8865°N, 88.9025°E, this area experiences significant seasonal variation in solar energy production that makes it moderately suitable for solar PV installations.

Seasonal Solar Energy Production

The location shows strong seasonal patterns in solar energy output. Spring emerges as the most productive season, generating 5.82 kWh per day for each kW of installed solar capacity. Summer follows as the second-best season with 4.75 kWh/day per kW, while autumn maintains decent production at 4.47 kWh/day per kW. Winter presents the biggest challenge for solar generation in Sherpur, Rajshahi Division, with output dropping to just 3.80 kWh/day per kW. This represents a significant 35% reduction compared to spring production levels, which potential solar users should factor into their energy planning. For optimal year-round performance, solar panels should be installed at a fixed tilt angle of 23 degrees facing south. This angle maximizes total annual energy production by accounting for the sun's changing position throughout the seasons and the area's specific latitude.

Environmental and Weather Challenges

Several local factors in Sherpur can significantly impact solar energy production and require careful consideration during installation:

• Monsoon rains and flooding: Bangladesh experiences intense monsoon seasons that bring heavy rainfall and potential flooding, which can damage solar equipment and reduce sunlight reaching panels
• High humidity and dust: The tropical climate creates conditions where dust and moisture can accumulate on panel surfaces, reducing efficiency
• Cyclones and severe weather: The region is susceptible to tropical cyclones and severe storms that can physically damage solar installations
• Temperature extremes: High temperatures during summer months can reduce panel efficiency, while humidity accelerates equipment degradation

Preventative Installation Measures

To maximize solar energy production despite these challenges, several protective measures should be implemented:

• Elevated mounting systems: Install panels on raised structures or rooftops well above potential flood levels
• Robust structural support: Use reinforced mounting systems designed to withstand high winds and storm conditions
• Regular cleaning protocols: Establish routine panel cleaning schedules to remove dust, debris, and moisture buildup
• Quality weatherproofing: Ensure all electrical connections and inverters are properly sealed against moisture and humidity
• Drainage systems: Install proper drainage around ground-mounted systems to prevent water accumulation

Despite these challenges, Sherpur's solar potential remains viable, particularly during the high-production spring and summer months. Proper installation techniques and maintenance can help overcome most environmental obstacles and ensure reliable solar energy generation 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 Sherpur

Seasonal solar PV output for Latitude: 24.8865, Longitude: 88.9025 (Sherpur, 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 Sherpur, Bangladesh

To maximize your solar PV system's energy output in Sherpur, Bangladesh (Lat/Long 24.8865, 88.9025) 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 Sherpur, 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 Sherpur, 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	19° 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 Sherpur, 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 Sherpur, 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 Sherpur, Bangladesh

Topography Around Sherpur, Bangladesh

The landscape surrounding Sherpur in north-central Bangladesh is characterized by relatively flat terrain with gentle undulations typical of the greater Bengal Delta region. This area sits within the broader Mymensingh division and forms part of the vast alluvial plains that dominate much of Bangladesh's geography. The elevation remains consistently low across the region, with minimal variation in height that creates an expansive, level terrain stretching in all directions. The topography consists primarily of fertile alluvial soil deposited over millennia by the region's river systems. These flat plains are interspersed with numerous water bodies including rivers, canals, ponds, and seasonal wetlands that are integral to the local ecosystem and agricultural practices. The Old Brahmaputra River flows through the broader region, contributing to the area's characteristic flat, well-drained landscape. Agricultural land dominates the visual landscape, with extensive rice paddies, crop fields, and scattered rural settlements creating a patchwork pattern across the plains. The terrain lacks significant hills, ridges, or elevated areas, maintaining a remarkably consistent elevation profile that extends well beyond the immediate vicinity of Sherpur town.

Areas Most Suitable for Large-Scale Solar PV Development

The extensive flat agricultural plains surrounding Sherpur present excellent opportunities for large-scale solar photovoltaic installations. The most promising areas lie in the open agricultural zones to the north and west of the town center, where large contiguous parcels of relatively flat land could accommodate substantial solar arrays without significant grading or terrain modification requirements. Areas with minimal tree coverage and away from the denser water body networks would be particularly well-suited for solar development. The agricultural plains extending toward the northwest offer especially favorable conditions, with their expansive flat terrain and reduced interference from existing infrastructure. These zones provide the space necessary for utility-scale solar installations while maintaining adequate distance from residential areas. The southeastern agricultural areas also present strong potential, particularly where the terrain remains consistently level and free from frequent flooding patterns. These locations benefit from the same flat topography while offering good accessibility for construction and maintenance activities. When selecting specific sites, areas with established road access and proximity to existing electrical infrastructure would be most practical for development. The flat terrain throughout the region means that solar panel orientation and spacing can be optimized without concerns about shading from topographical features, making virtually any sufficiently large flat agricultural area a viable candidate for solar PV development.
