Solar PV Analysis of Bac Ninh, Vietnam
Bac Ninh, Bắc Ninh Province, Vietnam is a decent location for generating solar energy throughout the year due to its tropical climate where sunlight is consistent most of the year. The amount of electricity that can be produced from each kilowatt of installed solar varies by season, with the highest output in summer at 5.53 kilowatt-hours per day and the lowest in winter at 3.24 kilowatt-hours per day.
This means that if you install solar panels here, they will generate more electricity during summer and less during winter, but still a reasonable amount throughout all seasons. However, to maximize your total yearly energy production from these solar panels, they should ideally be tilted at an angle of 18 degrees facing south.
There could be several local factors that might affect solar production in Bac Ninh such as weather conditions (like monsoon rains or cloudy days), environmental factors (like dust or pollution), or topographical features (like mountains or tall buildings casting shadows on the panels). Any of these could reduce the amount of sunlight reaching your panels and thus lower their energy output.
To prevent these issues and ensure greater energy production:
1) Install your panels in a location where they won't be shaded by nearby obstacles.
2) Regularly clean your panels to remove any dust or debris which might block sunlight.
3) Consider using tracking systems which can adjust panel orientation throughout the day to follow the sun's path and maximise exposure.
4) If possible, consider installing additional storage systems like batteries to store excess power generated during peak times for use when generation is low due to weather conditions.
So overall while there are some challenges associated with producing solar power in Bac Ninh due mainly to seasonal variations in sunlight intensity and potential local obstacles blocking light access – it's definitely feasible with careful planning and maintenance.
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 160 locations across Vietnam. 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 Bac Ninh
Seasonal solar PV output for Latitude: 21.1858, Longitude: 106.0746 (Bac Ninh, Vietnam), 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 18° South in Bac Ninh, Vietnam
To maximize your solar PV system's energy output in Bac Ninh, Vietnam (Lat/Long 21.1858, 106.0746) throughout the year, you should tilt your panels at an angle of 18° 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 Bac Ninh, Vietnam
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 Bac Ninh, Vietnam. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 18° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 5° South in Summer | 26° South in Autumn | 37° South in Winter | 13° 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 Bac Ninh, Vietnam
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 Bac Ninh, Vietnam.
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 Bac Ninh, Vietnam
Bac Ninh, Vietnam is situated in the Red River Delta and is mostly flat with some small hills. The region has a tropical monsoon climate with high humidity levels throughout the year. It has abundant sunlight, making it suitable for solar PV installations.
As for specific areas suited to large-scale solar PV, it would be ideal to consider regions that are relatively flat and open, with minimal shading from trees or buildings. These could include agricultural lands or unused industrial zones that are close to power transmission lines for easy connection to the grid.
However, a detailed site-specific assessment would be required before any large-scale solar project can be initiated. This should take into account not only topography and sunlight availability but also factors like land use policies, environmental impact, proximity to electrical grids and infrastructure development costs.
In addition, while Bac Ninh's climate is generally favorable for solar energy production, seasonal variations such as monsoon rains could potentially affect output. Therefore any feasibility study should also consider these climatic factors.
Vietnam solar PV Stats as a country
Vietnam ranks 9th in the world for cumulative solar PV capacity, with 16,660 total MW's of solar PV installed. Each year Vietnam is generating 171 Watts from solar PV per capita (Vietnam ranks 30th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Vietnam?
Yes, there are several incentives for businesses wanting to install solar energy in Vietnam. The government has implemented a number of policies and programs to encourage the development of renewable energy sources, including solar energy. These include tax exemptions, preferential loans, and feed-in tariffs for electricity generated from solar power plants. Additionally, the government has established a Renewable Energy Development Fund to provide financial support for projects related to renewable energy sources such as solar power.
