In Ho Chi Minh City, Vietnam (latitude: 10.8230989, longitude: 106.6296638), solar power generation is highly suitable due to the consistent sunlight received throughout most of the year. The average daily energy production per kW of installed solar capacity varies by season, with 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.
Higher energy production can be expected during Spring and Summer months as a result of longer daylight hours and more intense sunlight during these periods, as well as increased panel efficiency due to higher temperatures. There are no significant weather conditions or other local factors that would impede solar power generation at this location.
To maximize efficiency and ensure optimal performance even on cloudy days when direct sunlight may not be available, it is recommended that fixed solar panels be installed at a tilt angle of 10 degrees facing South. This orientation will help capture the maximum amount of sunlight throughout the year while minimizing potential shading or obstructions from surrounding structures or vegetation.
In summary, Ho Chi Minh City's geographical location makes it an excellent site for generating solar power year-round with minimal challenges related to environmental or topographical factors. By installing panels at the appropriate tilt angle and ensuring proper maintenance practices are followed, residents can expect reliable and efficient energy production from their solar installations throughout all seasons.
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 42 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 Ho Chi Minh City
Seasonal solar PV output for Latitude: 10.8230989, Longitude: 106.6296638 (Ho Chi Minh City, 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 Ho Chi Minh City, Vietnam
To maximize your solar PV system's energy output in Ho Chi Minh City, Vietnam (Lat/Long 10.8230989, 106.6296638) 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 Ho Chi Minh City, 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 Ho Chi Minh City, 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 | 16° 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 Ho Chi Minh City, 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 Ho Chi Minh City, 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 Ho Chi Minh City, Vietnam
The topography around Ho Chi Minh City is generally flat with some low hills. Areas to the east and south of the city are particularly well suited for large scale solar PV, as they have more open space with fewer obstacles that could block sunlight. The areas further away from the city tend to have less light pollution, allowing for more efficient solar energy production. Additionally, these areas are also typically at higher elevations which can help increase efficiency.
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.
