Solar PV Analysis of Pak Kret, Thailand
Pak Kret, Nonthaburi, Thailand is a pretty good place for generating solar energy year-round. This is because it's located in the Tropics where sunlight is consistent throughout most of the year. The amount of electricity you can expect to generate from each kilowatt (kW) of installed solar panels varies slightly by season but stays relatively high: about 5.91kWh per day in summer, 5.02kWh per day in autumn, 5.97kWh per day in winter, and 6.05kWh per day in spring.
The best times to generate solar energy at this location are during the spring and winter when daily output can reach up to approximately 6 kWh/day for each kW of installed solar panels.
If you're installing fixed-panel solar PV at this location, tilting your panels at an angle of 13 degrees towards the south would maximize your total yearly production.
However, there might be some local factors that could potentially reduce your solar production here. For instance, Pak Kret experiences a tropical monsoon climate which means it has a rainy season that could potentially limit sunlight exposure on certain days or weeks throughout the year.
To help ensure greater energy production despite these potential issues, you could consider installing tracking systems that move your panels so they're always facing directly towards the sun or use battery storage systems to store excess power on sunny days for use during less sunny periods or at night time.
Also maintaining clear space around your installation and keeping them clean will also help ensure maximum sun exposure and efficiency from your panels.
In conclusion while there might be some challenges due to weather conditions overall Pak Kret's consistent tropical sunshine makes it an ideal location for generating renewable energy through solar PV installations all year round.
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 Pak Kret
Seasonal solar PV output for Latitude: 13.9181, Longitude: 100.4974 (Pak Kret, 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 Pak Kret, Thailand
To maximize your solar PV system's energy output in Pak Kret, Thailand (Lat/Long 13.9181, 100.4974) 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 Pak Kret, 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 Pak Kret, 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 Pak Kret, 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 Pak Kret, 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 Pak Kret, Thailand
Pak Kret, Thailand is located in the central plains of the country. This area is generally flat with some small hills and is surrounded by several rivers, including the Chao Phraya River. The region has a tropical climate, which means it experiences high temperatures and rainfall throughout the year.
The relatively flat topography of this region makes it suitable for large-scale solar PV installations. Areas that are less populated or used for agriculture could be potential sites for such installations. Additionally, areas near to existing electrical infrastructure would be beneficial to minimize transmission costs.
However, other factors also need to be considered when determining suitability for solar PV installation including local weather patterns (amount of sunlight), land use restrictions, environmental impact assessments and proximity to demand centers (cities or industrial areas). It's also worth noting that while Thailand does have a significant amount of sunlight suitable for solar power generation; its monsoon season can limit solar energy production due to cloud cover and heavy rains.
As per specific locations within Pak Kret or nearby that would be most suited for large-scale solar PV installations; this would require a more detailed site-specific assessment involving on-the-ground surveys and geographical information system (GIS) analyses.
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.
