Hưng Yên, Vietnam presents a reasonably good location for year-round solar energy generation, though it's not among the most ideal tropical locations. Located in the tropics where sunlight remains fairly consistent throughout the year, this area experiences the typical wet and dry seasonal patterns rather than traditional temperature-based seasons.

Solar Energy Production Potential

The solar energy output at this location varies moderately throughout the year. Spring emerges as the peak season for solar generation, producing 6.45kWh per day per kW of installed solar capacity. Summer follows closely with 5.96kWh/day, while winter maintains decent production at 5.75kWh/day. Autumn shows the lowest output at 5.07kWh/day, though this still represents reasonable solar potential. For optimal year-round performance, solar panels should be installed at a fixed tilt angle of 11 degrees facing south. This angle maximizes total annual energy production by accounting for the sun's path throughout the year and the location's specific latitude.

Environmental and Weather Challenges

Several factors in Hưng Yên can significantly impact solar panel performance and require careful consideration during installation:

• High humidity and frequent rainfall during monsoon seasons can reduce solar irradiance and create maintenance challenges
• Heavy monsoon rains may cause flooding or water damage to electrical components
• Strong winds during storm seasons can damage panels or mounting systems
• Dust and debris accumulation during dry periods reduces panel efficiency
• Salt air from coastal proximity can accelerate corrosion of metal components

Preventative Measures for Better Performance

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

• Install robust waterproof electrical enclosures and use marine-grade wiring to prevent moisture damage
• Design mounting systems to withstand high winds and ensure proper drainage
• Implement regular cleaning schedules, particularly after dust storms or before peak production seasons
• Use corrosion-resistant materials like anodized aluminum or stainless steel for mounting hardware
• Install panels with adequate spacing for air circulation to reduce humidity-related issues
• Consider micro-inverters or power optimizers to minimize impact when individual panels are shaded or dirty

Despite these environmental challenges, Hưng Yên's consistent tropical sunlight and reasonable seasonal variation make it a viable location for solar energy generation, provided proper installation techniques and maintenance practices are followed.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Solar output per kW of installed solar PV by season in Hưng Yên, Bình Phước Province

Seasonal solar PV output for Latitude: 11.6306, Longitude: 106.7319 (Hưng Yên, Bình Phước Province, 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 11° South in Hưng Yên, Bình Phước Province, Vietnam

To maximize your solar PV system's energy output in Hưng Yên, Bình Phước Province, Vietnam (Lat/Long 11.6306, 106.7319) throughout the year, you should tilt your panels at an angle of 11° 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 Hưng Yên, Bình Phước Province, 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 Hưng Yên, Bình Phước Province, Vietnam. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 11° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
4° North in Summer	18° South in Autumn	27° South in Winter	6° 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 Hưng Yên, Bình Phước Province, 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 Hưng Yên, Bình Phước Province, Vietnam.

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 Hưng Yên, Bình Phước Province, Vietnam

Topographical Features Around Hưng Yên

The area surrounding Hưng Yên in northern Vietnam is characterized by remarkably flat terrain that forms part of the extensive Red River Delta plain. This low-lying region sits at elevations typically ranging from just 2 to 10 meters above sea level, creating an almost pancake-flat landscape that stretches for kilometers in every direction. The topography consists primarily of alluvial deposits laid down over thousands of years by the Red River and its tributaries, resulting in fertile sedimentary soils that have been shaped into an intricate patchwork of agricultural fields.

The landscape is dominated by an extensive network of rice paddies, interspersed with small villages, narrow waterways, and raised pathways called dikes that serve both as flood protection and transportation routes. These agricultural areas are punctuated by occasional small hills or mounds that rarely exceed 20-30 meters in height, representing ancient river terraces or isolated geological formations. The region experiences a subtropical monsoon climate with distinct wet and dry seasons, which has influenced both the natural topography and human modification of the landscape over centuries.

Drainage patterns across the area follow a complex system of natural and artificial waterways, including irrigation canals, drainage ditches, and small tributaries that eventually flow toward the Red River. The terrain slopes very gently toward the northeast, creating subtle undulations in an otherwise level plain. During the wet season, much of the lower-lying agricultural land becomes waterlogged or flooded, while the slightly elevated areas and artificial embankments remain dry.

Optimal Areas for Large-Scale Solar Development

The flat topography around Hưng Yên presents excellent opportunities for large-scale solar photovoltaic installations, particularly in areas that are elevated above the seasonal flood zones. The most suitable locations would be found on the slightly higher ground that sits 5-10 meters above sea level, where the risk of flooding is minimal and the terrain requires little to no grading for solar panel installation.

Former agricultural areas that have been converted to industrial or commercial use represent prime candidates for solar development, as they typically feature level ground with existing infrastructure access. These zones often benefit from proximity to electrical transmission lines and road networks while avoiding the complications associated with active farming operations. Areas near industrial parks or along major transportation corridors would be particularly advantageous for large installations.

The raised embankments and higher terraces scattered throughout the region offer additional opportunities for solar development, as these elevated positions provide natural drainage and reduced flood risk. These locations also tend to have fewer conflicts with agricultural activities and may be more readily available for alternative land uses. The consistent flatness of the terrain means that solar panels can be oriented optimally without concerns about shading from nearby hills or significant variations in ground elevation.

Locations that should be avoided for solar installations include the active rice paddies and low-lying areas that flood seasonally, as well as zones immediately adjacent to major waterways where soil stability might be compromised. The ideal sites would combine the natural advantages of the flat terrain with strategic positioning on slightly elevated ground that remains dry throughout the year while maintaining good access to transportation and electrical infrastructure.
