Solar PV Analysis of Rangpur City, Bangladesh
Rangpur City in Bangladesh is a pretty good spot for generating energy through solar panels all year round. The amount of electricity you can get from each kilowatt of installed solar varies slightly throughout the year. You'll get about 4.73 kilowatt-hours per day in the summer, 4.83 in autumn, 4.11 in winter, and the highest output of 5.74 in spring.
Spring seems to be the best time of year for producing solar power at this location because it has the highest daily output on average. However, every season still provides a substantial amount of energy which makes Rangpur City a suitable place for solar panels.
If you're installing fixed panel installations here, tilting them at an angle of 25 degrees towards the south is ideal to get maximum power production throughout the year.
As far as environmental or weather factors that could affect your solar production go, there might be some challenges but they aren't significant enough to outweigh benefits. For instance, during monsoon season there could be less sunlight due to heavy rainfall and clouds which may reduce your energy generation somewhat.
However, there are ways around these issues too! To ensure greater energy production despite these factors you could consider using more efficient panels that work better under cloudy conditions or use tracking systems that follow sun’s position across sky ensuring maximum exposure even when sun isn’t directly overhead.
Also keep regular maintenance practices like cleaning dust and debris off your panels so they can absorb as much sunlight as possible without any hindrances.
In conclusion; while minor obstacles exist such as seasonal weather changes - with proper planning and precautions taken into account - Rangpur city remains an excellent choice for harnessing renewable solar energy effectively all-year-round!
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 Rangpur City
Seasonal solar PV output for Latitude: 25.7277, Longitude: 89.2805 (Rangpur City, 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 Rangpur City, Bangladesh
To maximize your solar PV system's energy output in Rangpur City, Bangladesh (Lat/Long 25.7277, 89.2805) 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 Rangpur City, 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 Rangpur City, 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 | 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 Rangpur City, 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 Rangpur City, 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 Rangpur City, Bangladesh
Rangpur City is located in the northern part of Bangladesh and is generally characterized by a flat plain, as is typical for most parts of the country. The region experiences a tropical monsoon climate with relatively high temperatures throughout the year.
The topography around Rangpur City consists mainly of fertile plains, which are well-suited to agriculture but not necessarily ideal for large-scale solar PV installations due to potential conflicts with food production. However, there may be opportunities for dual-use systems that combine agriculture and photovoltaics (AgriPV).
For large-scale solar PV projects, areas that are less suitable for cultivation or habitation would be more appropriate. This includes barren lands, fallow lands or rooftops in urban areas. Also, areas close to existing transmission infrastructure would be beneficial to reduce costs associated with power evacuation.
To identify specific sites suitable for large-scale solar PV within this region, more detailed analysis would need to be conducted considering factors like land availability and use, local climatic conditions (solar irradiation levels), proximity to grid infrastructure among others.
It's also worth noting that Bangladesh has a high population density so finding large tracts of unused land might prove challenging. Therefore innovative solutions such as floating solar panels on water bodies could also be considered since Bangladesh has numerous rivers and ponds.
Please note: Solar energy projects should always consider environmental impacts and aim at minimizing them through careful planning and implementation processes.
Bangladesh solar PV Stats as a country
Bangladesh ranks 63rd in the world for cumulative solar PV capacity, with 329 total MW's of solar PV installed. Each year Bangladesh is generating 2 Watts from solar PV per capita (Bangladesh ranks 87th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Bangladesh?
Yes, there are incentives for businesses wanting to install solar energy in Bangladesh. The government of Bangladesh has implemented a number of policies and programs to promote the use of renewable energy sources such as solar power. These include tax exemptions, subsidies, and other financial incentives for businesses that install solar systems. Additionally, the government has set up a Renewable Energy Fund which provides grants to support research and development activities related to renewable energy technologies.
