Solar PV Analysis of Khlong Luang, Thailand
The location at Khlong Luang, Pathum Thani, Thailand is quite suitable for generating solar energy throughout the year. This is due to its tropical climate where sunlight is consistent most of the time and seasons are more characterized by wet and dry periods rather than drastic temperature changes.
Looking at the electricity output per kilowatt (kW) of installed solar panels, we see that it doesn't change drastically from season to season: 5.91 kWh/day in summer, 5.01 kWh/day in autumn, 5.88 kWh/day in winter, and 6.03 kWh/day in spring.
This means that you can expect a fairly steady production of electricity from your solar panels all year round - with slightly less power generated during autumn but not by much.
In terms of when's best to generate solar power at this location? The answer would be spring as it has the highest daily output followed closely by summer and winter while autumn provides slightly lower output.
For fixed panel installations here, tilting them towards South at an angle of about 13 degrees will maximize total yearly production from your solar PV system because this position allows maximum exposure to sunlight over the course of a day throughout different seasons.
However, there could be local factors that might hinder optimal solar production like heavy rainfall or cloudy weather during monsoon seasons which usually occur twice a year in Thailand – May till October and November till March – limiting sun exposure hence reducing energy generation capacity during these periods.
To mitigate against these potential issues when installing your panels:
1) You might want to consider using high-quality panels designed for low-light conditions.
2) Install additional PV modules if space allows so you can still achieve desired energy levels even on less sunny days.
3) Regular cleaning & maintenance should also be performed especially after heavy rainfalls or storms as dust or debris on panel surfaces can reduce their efficiency significantly.
4) A good drainage system around installation site helps prevent water accumulation which can damage the system or reduce its efficiency.
Overall, Khlong Luang, Pathum Thani, Thailand is a great spot for solar energy production with just a few considerations to keep in mind.
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 Khlong Luang
Seasonal solar PV output for Latitude: 14.0712, Longitude: 100.6549 (Khlong Luang, 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 13° South in Khlong Luang, Thailand
To maximize your solar PV system's energy output in Khlong Luang, Thailand (Lat/Long 14.0712, 100.6549) throughout the year, you should tilt your panels at an angle of 13° 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 Khlong Luang, 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 Khlong Luang, Thailand. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 13° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 2° North in Summer | 20° South in Autumn | 30° South in Winter | 7° 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 Khlong Luang, 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 Khlong Luang, 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 Khlong Luang, Thailand
Khlong Luang is located in the Pathum Thani Province of Thailand. The topography of this area is generally flat, with low-lying plains and some scattered hills. Most of the land around Khlong Luang is used for agriculture, including rice paddies and orchards.
The climate in Khlong Luang, like most parts of Thailand, is tropical monsoon type which means it has plenty of sunlight throughout the year making it suitable for solar PV installation.
Considering topography and land use, large-scale solar PV installations would be best suited to areas that are relatively flat and open. Agricultural lands could potentially host solar panels without disrupting farming activities through agrovoltaic systems where crops can be grown under solar panels.
However, any plans for large-scale installations should consider potential impacts on local ecosystems or agricultural practices. Additionally, proximity to existing power infrastructure would also need to be taken into account as this will affect the cost and feasibility of transmitting electricity generated by a large-scale solar farm back to the grid.
It's important to note that specific site assessments would still be necessary before deciding on an exact location for a large scale Solar PV farm because factors such as soil stability also play a significant role in determining suitability.
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.
