Solar PV Analysis of Bien Hoa, Vietnam
Bien Hoa, Đồng Nai Province, Vietnam is a good location for generating solar energy throughout the year because it's located in the tropics where sunlight is consistent most of the time. The amount of electricity that can be produced from each kilowatt (kW) of installed solar varies slightly with each season: it generates about 5.58 kWh/day in summer, 4.92 kWh/day in autumn, 5.61 kWh/day in winter and 6.26 kWh/day in spring.
The best times to generate solar power at this location are during spring and summer when there's more sunlight available per day compared to other seasons.
For a fixed panel installation at this location, tilting panels at an angle of 10 degrees towards south will maximize total production from solar photovoltaic (PV) system throughout the year.
However, local factors such as weather conditions and environmental issues could potentially impede solar production here. For instance, Bien Hoa experiences a tropical wet-dry climate with high rainfall during the monsoon season which may affect the efficiency of solar panels due to cloud cover or dirt accumulation on panels from rainwater runoff.
To mitigate these potential challenges:
1) Regular maintenance including cleaning of panels should be carried out especially after heavy rains to remove any dirt or debris that might have accumulated on them.
2) Installing adjustable tilt mounts could also help maximize energy production by allowing adjustments based on seasonal changes.
3) Additionally, using high-quality PV modules with excellent performance under low light conditions would ensure better energy yield during cloudy days or rainy seasons.
4) Implementing proper water drainage systems around the installation site can prevent any possible water damage to equipment.
In summary, while Bien Hoa does offer favorable conditions for year-round solar power generation; considering local weather patterns and regular maintenance schedules are key aspects for efficient operation and longevity of installed 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 Bien Hoa
Seasonal solar PV output for Latitude: 10.9413, Longitude: 106.8221 (Bien Hoa, 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 10° South in Bien Hoa, Vietnam
To maximize your solar PV system's energy output in Bien Hoa, Vietnam (Lat/Long 10.9413, 106.8221) throughout the year, you should tilt your panels at an angle of 10° 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 Bien Hoa, 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 Bien Hoa, Vietnam. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 10° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 5° North in Summer | 17° South in Autumn | 26° South in Winter | 5° 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 Bien Hoa, 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 Bien Hoa, 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 Bien Hoa, Vietnam
Bien Hoa is located in the Dong Nai Province of southern Vietnam, on the Dong Nai River. The topography around Bien Hoa is relatively flat with some undulating terrain. The region has a tropical climate with high humidity and abundant sunshine throughout the year.
The flat areas surrounding Bien Hoa would be most suited for large-scale solar PV installations. This includes agricultural lands and other open spaces that receive ample sunlight throughout the year. These regions can accommodate ground-mounted solar panels which are typically used in large-scale operations.
However, it's important to consider environmental impacts before installing solar farms on agricultural lands or near natural habitats. Rooftop installations within urban areas like Bien Hoa city could also be a viable option, given enough space.
Also, considering Vietnam’s long coastline and numerous rivers including Dong Nai River near Bien Hoa, floating solar PV systems could also be an innovative solution where land resources are scarce.
Before any installation though, detailed site assessments should be conducted to evaluate factors such as local climate patterns (e.g., cloud cover), land use restrictions and availability of transmission infrastructure.
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.
