Solar PV Analysis of Kantang, Thailand
The location at Kantang, Trang, Thailand is quite suitable for generating energy through solar PV systems throughout the year. This is because it's located in the tropics where sunlight is consistent most of the year, and seasons are more defined by wet and dry periods rather than temperature fluctuations.
Looking at the amount of electricity that can be generated per kilowatt (kW) of installed solar power, we see good results across all seasons. In summer, you can expect about 5.42 kilowatt-hours (kWh) per day; in autumn it's slightly less with 4.75 kWh/day; winter sees a rise to 5.75 kWh/day; and spring tops out with an impressive 6.12 kWh/day.
These figures suggest that while there might be some variation in output due to seasonal changes, generally any time of year would be good for generating solar power at this location - although spring appears to be optimal.
For fixed panel installations here, tilting your panels at an angle of 7 degrees towards South will give you maximum total yearly production from your solar PV system.
However, there could potentially be environmental or weather factors that might impact solar production here – primarily related to the region’s wet season which could result in prolonged cloud cover reducing sunlight exposure or heavy rainfall causing potential physical damage to panels.
To mitigate these risks when installing your system:
1) Consider using high-quality durable panels designed to withstand harsh weather conditions.
2) Regular maintenance checks should also help identify any issues early on so they can be addressed before significantly impacting energy production.
3) Depending on how severe the rainy season gets locally, you may want to consider a backup storage solution like battery storage systems for times when sunlight exposure is minimal.
4) Finally remember that even during cloudy days some electricity generation still occurs though not as much as sunny days – so don’t write off those rainy months entirely!
In summary: While there are some challenges to consider, Kantang, Trang, Thailand is generally a great location for solar energy production throughout the year.
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 88 locations across Thailand. 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 Kantang
Seasonal solar PV output for Latitude: 7.4184, Longitude: 99.5091 (Kantang, Thailand), 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 7° South in Kantang, Thailand
To maximize your solar PV system's energy output in Kantang, Thailand (Lat/Long 7.4184, 99.5091) throughout the year, you should tilt your panels at an angle of 7° 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 Kantang, Thailand
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 Kantang, Thailand. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 7° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 9° North in Summer | 13° South in Autumn | 22° South in Winter | 2° 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 Kantang, Thailand
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 Kantang, Thailand.
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 Kantang, Thailand
Kantang is located in the Trang province of Thailand, which features a tropical monsoon climate. The area around Kantang is primarily flat with some small hills and valleys, making it suitable for solar PV installations. The region also has a significant amount of agricultural land that could potentially be used for large-scale solar projects.
The best locations for large-scale solar PV would likely be areas with plenty of sunlight exposure throughout the year and minimal shading from trees or buildings. This might include open fields or cleared land in the surrounding countryside. Additionally, areas near existing infrastructure (like roads and power lines) would be advantageous to facilitate installation and connection to the grid.
However, when planning such projects, one must also consider factors like local regulations on land use, potential environmental impact on flora and fauna as well as social impacts on local communities. For instance, converting agricultural lands into solar farms might not always be feasible due to food security concerns or resistance from local farmers.
In terms of specific nearby locations suitable for large scale Solar PV installations; Thung Khai Botanic Garden area (due to its relatively open space), Huai Yot District (owing to its vast unobstructed landscapes), Nayong District (for its topography) are some potential sites worth exploring further based on their geographical suitability.
But again these suggestions should undergo rigorous feasibility studies considering all factors including ecological impact before any implementation decision is taken.
Thailand solar PV Stats as a country
Thailand ranks 26th in the world for cumulative solar PV capacity, with 3,049 total MW's of solar PV installed. This means that 2.90% of Thailand's total energy as a country comes from solar PV (that's 29th in the world). Each year Thailand is generating 44 Watts from solar PV per capita (Thailand ranks 54th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Thailand?
Yes, there are several incentives for businesses wanting to install solar energy in Thailand. The Thai government offers a number of tax incentives and subsidies for businesses that install solar energy systems. These include a 30% corporate income tax deduction on the cost of installing solar panels, as well as an exemption from import duties on certain components used in the installation process. Additionally, businesses can benefit from net metering policies which allow them to sell excess electricity generated by their solar system back to the grid at a premium rate. Finally, businesses may also be eligible for grants and other financial assistance from various government agencies and private organizations.
