Solar PV Analysis of Lam Luk Ka, Thailand
The location at Lam Luk Ka, Pathum Thani, Thailand is very suitable for generating energy through solar PV year-round. This is due to its tropical climate where sunlight is consistent throughout most of the year. The amount of electricity that can be produced from each kW of installed solar varies slightly by season but remains relatively high all year round: 5.91kWh/day in Summer, 5.02kWh/day in Autumn, 5.97kWh/day in Winter, and 6.05kWh/day in Spring.
Given these figures, it's clear that the best times for solar energy production are during the Spring and Winter seasons when sunlight yield per day is highest on average; however, even during Autumn and Summer the output remains substantial.
For a fixed panel installation at this location, tilting panels at an angle of 13 degrees South would maximize total yearly production from solar PV—this means setting up your panels so they're angled towards the south to catch as much sunlight as possible over the course of a day.
However, there could be some potential obstacles to optimal solar production in Lam Luk Ka due to environmental or weather factors specific to this area. For example:
1) Monsoon Season: In Thailand's tropical climate heavy rainfall can occur during monsoon season (generally between May and October). This could potentially reduce sunlight exposure for your panels temporarily.
Preventative Measure: Ensure robust waterproofing measures are taken when installing your panels and consider investing in high-quality durable equipment designed to withstand heavy rainfalls.
2) Dust & Pollution: Depending on local activities such as farming or industry there may be dust or pollution which could settle on your panels reducing their effectiveness.
Preventative Measure: Regular cleaning/maintenance schedule should help keep any buildup off your panels ensuring they remain effective.
3) Shading: Depending on exact placement there may be shading from nearby buildings/trees especially if they are tall.
Preventive Measure: Choose the installation site carefully to avoid shading as much as possible.
To sum up, Lam Luk Ka in Thailand is a very suitable location for solar energy production year-round with minor adjustments needed depending on seasonal and environmental factors.
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 Lam Luk Ka
Seasonal solar PV output for Latitude: 13.9332, Longitude: 100.7502 (Lam Luk Ka, 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 Lam Luk Ka, Thailand
To maximize your solar PV system's energy output in Lam Luk Ka, Thailand (Lat/Long 13.9332, 100.7502) 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 Lam Luk Ka, 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 Lam Luk Ka, 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 | 29° 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 Lam Luk Ka, 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 Lam Luk Ka, 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 Lam Luk Ka, Thailand
Lam Luk Ka is located in the Pathum Thani Province of Thailand, which is part of the central plain region. The area around Lam Luk Ka is relatively flat with low-lying plains and some small hills, making it suitable for agriculture. There are also several water bodies, including rivers and canals.
In terms of suitability for large-scale solar PV installations, areas with flat terrain and high sun exposure would be most appropriate. Given its location near the equator, Lam Luk Ka receives a good amount of sunlight throughout the year. So any open or unused agricultural lands could potentially be converted into solar farms.
However, there are other factors to consider as well like local regulations regarding land use and energy production; proximity to power grids or infrastructure for transmitting electricity; potential environmental impact on local ecosystems; social implications such as displacement of communities or changes in land use that might affect livelihoods etc.
Detailed feasibility studies would need to be conducted before identifying specific locations for large-scale solar PV installations. This would include analysis on solar irradiation levels using tools like GIS-based solar maps or satellite data along with ground-based surveys for understanding site-specific characteristics.
It's also worth mentioning that Thailand has been actively promoting renewable energy sources in recent years so there might already exist incentives or supportive policies at national/provincial level which could facilitate such projects.
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.
