Buon Ma Thuot, Đắk Lắk, Vietnam, located at 12.6674° N, 108.0528° E, presents a favorable environment for solar PV energy generation throughout the year. Situated in the tropics, this location benefits from consistent sunlight and experiences wet and dry seasons rather than traditional four-season weather patterns.

Seasonal Solar Performance

The solar energy output at Buon Ma Thuot varies across the meteorological seasons:

• Spring: 6.51 kWh/day per kW installed
• Summer: 5.57 kWh/day per kW installed
• Autumn: 4.02 kWh/day per kW installed
• Winter: 4.67 kWh/day per kW installed

Spring emerges as the most productive season, followed by summer. Even during the less productive autumn months, the output remains substantial, indicating year-round viability for solar energy generation.

Optimal Panel Positioning

For fixed panel installations in Buon Ma Thuot, Đắk Lắk, the ideal tilt angle to maximize year-round solar production is 11 degrees facing South. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's specific latitude.

Environmental Considerations

While Buon Ma Thuot offers favorable conditions for solar energy production, there are some environmental factors to consider. The region experiences a monsoon climate, with a distinct rainy season typically lasting from May to October. During this period, increased cloud cover and rainfall may temporarily reduce solar panel efficiency.

To mitigate the impact of these weather patterns, several preventative measures can be implemented:

• Install high-quality, weather-resistant solar panels designed to perform well in humid conditions
• Ensure proper drainage systems are in place to prevent water accumulation on panels
• Implement regular cleaning schedules to remove dust and debris, which can accumulate more quickly during dry seasons
• Consider using micro-inverters or power optimizers to minimize the impact of partial shading on overall system performance

By taking these precautions, solar installations in Buon Ma Thuot can maintain high levels of energy production throughout the year, capitalizing on the location's abundant sunlight and favorable positioning for solar PV systems.

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 Buon Ma Thuot

Seasonal solar PV output for Latitude: 12.6674, Longitude: 108.0528 (Buon Ma Thuot, 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 Buon Ma Thuot, Vietnam

To maximize your solar PV system's energy output in Buon Ma Thuot, Vietnam (Lat/Long 12.6674, 108.0528) 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 Buon Ma Thuot, 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 Buon Ma Thuot, 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
3° 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 Buon Ma Thuot, 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 Buon Ma Thuot, 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 Buon Ma Thuot, Vietnam

The area around Buon Ma Thuot, Vietnam, is characterized by a diverse and interesting topography. This city is located in the Central Highlands region of Vietnam, which is known for its elevated plateau landscape. The terrain surrounding Buon Ma Thuot is generally hilly and undulating, with elevations ranging from about 400 to 800 meters above sea level.

The city itself sits on a relatively flat area, but as you move outward, the landscape becomes more varied. To the east and northeast, you'll find gently rolling hills covered in lush vegetation, including coffee plantations for which the region is famous. These hills gradually give way to more rugged terrain as you approach the coastal mountains.

To the west and southwest, the land becomes more elevated, with steeper hills and some small mountain ranges. This area is part of the broader Central Highlands plateau, which extends into neighboring countries. The region is also dotted with numerous rivers and streams, creating valleys and contributing to the overall undulating nature of the landscape.

When considering areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, several factors come into play. The ideal locations would be relatively flat or gently sloping areas with good sun exposure throughout the day. Based on the topography around Buon Ma Thuot, the most suitable areas for solar PV would likely be found in the following regions:

1. The flatter areas immediately surrounding Buon Ma Thuot city, particularly to the north and east, where there are expanses of agricultural land that could potentially be repurposed.

2. The gently rolling hills to the east and northeast of the city, where there might be larger continuous areas with favorable slopes facing the sun.

3. Some of the broader valley floors between the hills and mountains, especially those oriented in an east-west direction to maximize sun exposure.

4. Cleared or less densely forested areas on the plateau to the west and southwest of the city, where elevation and open space could provide good solar potential.

It's important to note that while these areas may be topographically suitable, other factors such as land ownership, current land use (especially considering the importance of coffee cultivation in the region), environmental considerations, and proximity to electrical infrastructure would also need to be taken into account when planning large-scale solar PV installations.
