Saidpur, Rangpur Division, Bangladesh is located in the Northern Sub Tropics and shows strong potential for year-round solar energy generation, though with notable seasonal variations that make it a moderately good location for solar PV installations.
Seasonal Solar Performance
The location experiences its best solar production during spring, generating 5.75 kWh per day per kW of installed solar capacity. Summer and autumn maintain consistently good performance at 4.66 kWh/day and 4.64 kWh/day respectively. Winter shows the lowest output at 3.86 kWh/day per kW, representing about a 33% decrease from the peak spring production. Spring emerges as the ideal time for solar generation at this location, followed closely by the summer and autumn months. Even during the weaker winter period, the location still produces reasonable solar output, making it viable for year-round solar energy systems.Optimal Panel Installation
For fixed panel installations at Saidpur, Rangpur Division, the ideal tilt angle is 24 degrees facing south to maximize total year-round solar production. This angle is calculated based on the location's latitude and accounts for seasonal sun angle variations throughout the year.Environmental and Weather Challenges
Several significant local factors can impede solar production at this location:- Monsoon season brings heavy rainfall and extended cloud cover, particularly affecting summer and early autumn production
- High humidity levels throughout much of the year can reduce panel efficiency
- Dust accumulation during dry periods, especially in winter and spring
- Potential for severe weather events including cyclones and hailstorms
- Air pollution from industrial activities and biomass burning can reduce solar irradiance
Preventative Measures for Better Performance
To maximize energy production despite these challenges, several installation strategies should be considered:- Install panels with adequate spacing and ventilation to combat humidity-related efficiency losses
- Implement regular cleaning schedules, particularly during dusty periods
- Use mounting systems designed to withstand high winds and severe weather
- Consider anti-reflective coatings and self-cleaning panel surfaces
- Install proper drainage systems to handle heavy monsoon rains
- Use corrosion-resistant materials for all mounting hardware due to high humidity

Solar output per kW of installed solar PV by season in Saidpur
Seasonal solar PV output for Latitude: 25.7746, Longitude: 88.8889 (Saidpur, 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 24° South in Saidpur, Bangladesh
To maximize your solar PV system's energy output in Saidpur, Bangladesh (Lat/Long 25.7746, 88.8889) throughout the year, you should tilt your panels at an angle of 24° 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 Saidpur, 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 Saidpur, Bangladesh. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 24° 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 | 31° 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 Saidpur, 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 Saidpur, 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 Saidpur, Bangladesh
Topographical Overview of the Saidpur Region
The area surrounding Saidpur in northern Bangladesh is characterized by relatively flat terrain that forms part of the greater Gangetic Plain. This expansive alluvial plain stretches across much of northern Bangladesh and has been shaped over millennia by sediment deposits from the Ganges river system and its tributaries. The landscape around Saidpur sits at a modest elevation, creating a gently undulating terrain with minimal steep slopes or significant elevation changes. The region features predominantly agricultural land interspersed with scattered settlements and transportation corridors. Rice paddies dominate much of the immediate vicinity, creating a patchwork of rectangular fields that flood seasonally during monsoon periods. Between the agricultural areas, small villages and rural communities are connected by a network of roads ranging from major highways to narrow rural paths. Several rivers and waterways meander through the broader region, including smaller tributaries that feed into larger river systems. These waterways create natural boundaries and occasionally result in slightly more varied topography along their banks, though the overall character remains quite flat. The presence of these water sources also influences local drainage patterns and can create areas of seasonal flooding.Optimal Areas for Large-Scale Solar Development
The flat topography around Saidpur presents excellent opportunities for large-scale solar photovoltaic installations. Areas with minimal slopes and consistent elevation provide ideal conditions for mounting solar panels efficiently and cost-effectively. The most suitable locations would be found on higher ground that remains above seasonal flood levels while maintaining the flat characteristics that make installation and maintenance straightforward. Large tracts of unused or underutilized land away from prime agricultural areas would be most appropriate for solar development. These might include areas that are less suitable for intensive farming due to soil conditions or drainage issues, yet still offer the level terrain necessary for solar installations. Such locations would minimize conflicts with food production while taking advantage of the region's favorable topographical conditions. Areas with good access to existing electrical grid infrastructure would be particularly valuable for solar development. The flat terrain makes it relatively simple to construct access roads and transmission lines needed to connect solar installations to the broader electrical network. Proximity to existing substations or transmission corridors would reduce the infrastructure investment required to bring solar power online. The absence of significant hills, forests, or other natural obstacles in much of the surrounding area means that large solar installations could be developed without major site preparation challenges. This flat terrain also reduces the likelihood of shading issues between rows of solar panels, allowing for more efficient use of available land area. Areas slightly elevated above the immediate floodplain would offer the additional advantage of reduced risk from seasonal flooding while maintaining the beneficial flat topography.Bangladesh solar PV Stats as a country
