Solar PV Analysis of Narail, Bangladesh
Narail, Khulna Division, Bangladesh is a good location for solar energy production all year round. This is because it's in the tropics where sunlight stays pretty consistent throughout the year. The amount of electricity you can get from each kilowatt of solar power installed changes a bit with the seasons, but not by much.
In summer, you can expect about 4.61 kilowatt-hours (kWh) per day for every kilowatt (kW) of solar panels you have installed. In autumn, this goes up slightly to 4.72 kWh/day per kW; in winter it drops to 4.08 kWh/day per kW and then goes up again in spring to about 5.99 kWh/day per kW.
The best time of year for generating solar energy at this location would be during the spring season when output reaches nearly 6kWh/day per kW due to increased sunlight availability.
For fixed panel installations at this location, tilting your panels at an angle of 22 degrees facing south will give you the best overall results for the whole year.
As far as local factors that might affect your solar production, Narail is known for having wet and dry seasons like many tropical areas do - so there could be less sun during rainy periods or if there are lots of clouds around often which could reduce your output somewhat.
To help make sure you're getting as much energy as possible from your solar installation despite these factors, consider installing more than just one set of panels so that even on cloudy days some light gets through to some part them; also try using high-efficiency panels that can still generate useful amounts of electricity even under less-than-ideal conditions like partial shade or indirect light.
Finally remember regular maintenance – cleaning off any dust or debris that accumulates on your panels – will also help ensure they're working their best no matter what time of year it is.
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.
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 Narail
Seasonal solar PV output for Latitude: 23.1404, Longitude: 89.6383 (Narail, 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 22° South in Narail, Bangladesh
To maximize your solar PV system's energy output in Narail, Bangladesh (Lat/Long 23.1404, 89.6383) throughout the year, you should tilt your panels at an angle of 22° 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 Narail, 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 Narail, Bangladesh. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 22° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 7° South in Summer | 29° South in Autumn | 38° South in Winter | 17° 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 Narail, 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 Narail, 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 Narail, Bangladesh
Narail, Bangladesh is situated in the southwestern part of the country and is characterized by a flat topography with an average elevation of around 4-6 meters above sea level. The region falls under the Ganges Delta which is largely composed of alluvial soils - making it fertile but also prone to flooding.
The climate in Narail is tropical, with a high amount of rainfall throughout the year. However, it does receive ample sunlight making solar PV installations feasible. For large-scale solar PV plants, areas that are less prone to flooding and have minimal vegetation would be most suited.
Nearby areas like Lohagara Upazila or Kalia Upazila which have relatively less dense population could be considered for such projects. Also, any unused agricultural land or brownfield sites could potentially be used for large scale solar projects as well.
However, specific feasibility studies would need to be conducted to assess factors like local weather patterns (including cloud cover), soil stability, availability of infrastructure for power transmission and local regulations related to land use and renewable energy projects.
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.
