The location at Sing Buri, Thailand is very good for year-round energy generation via solar photovoltaic (PV) systems due to its tropical climate. This means that the amount of sunlight it receives is fairly consistent throughout the year, which is crucial for solar power production.
Based on the data provided, it seems like all seasons are suitable for generating solar energy in Sing Buri as there's not a huge difference between them. The electricity output per kilowatt of installed solar ranges from 5.01 kWh/day in Autumn to 6.03 kWh/day in Spring, with Summer and Winter also providing more than 5.8 kWh/day each.
However, Spring appears to be slightly more ideal than other seasons as it has the highest daily output of 6.03kWh per day per kW of installed solar PV system followed closely by Summer and Winter with outputs above 5.8kWh per day.
For fixed panel installations at this location, tilting panels towards south at an angle of about 14 degrees can help maximize total year-round production from your solar PV system since this angle would allow panels to capture maximum sunlight throughout different times of a day and different seasons.
As far as environmental or weather factors are concerned that could potentially impede solar production at this location; heavy rainfall or monsoon season might temporarily reduce efficiency due to cloud cover but given that such conditions do not persist all-year round they should not significantly impact overall annual performance.
To ensure greater energy production despite these potential challenges, regular maintenance such as cleaning panels after heavy rainfalls can help keep them efficient by removing any dirt or debris blocking sunlight penetration onto your panels' surface.
In conclusion: Sing Buri is an excellent place for installing a Solar PV System because even though seasonal changes may affect productivity slightly; overall you can expect consistently high levels of electricity generation across all four seasons if you maintain your system properly and position it correctly according to the sun's path and angle.
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 Sing Buri
Seasonal solar PV output for Latitude: 14.8682, Longitude: 100.3776 (Sing Buri, 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 14° South in Sing Buri, Thailand
To maximize your solar PV system's energy output in Sing Buri, Thailand (Lat/Long 14.8682, 100.3776) throughout the year, you should tilt your panels at an angle of 14° 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 Sing Buri, 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 Sing Buri, Thailand. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 14° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 1° North in Summer | 21° South in Autumn | 30° South in Winter | 8° 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 Sing Buri, 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 Sing Buri, 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 Sing Buri, Thailand
Sing Buri, Thailand is located in the central part of the country and its topography is mainly flat lowland. The region consists mostly of plains due to its location on the Chao Phraya river delta. It has some small hills, but overall it lacks significant elevation changes.
The climate in Sing Buri is tropical savanna which means it has high temperatures throughout the year and two distinct seasons - wet and dry. This makes it a good location for solar PV installations as there's plenty of sunlight available most of the year.
For large scale solar PV installations, areas with open fields or unused agricultural land would be ideal as they offer unobstructed access to sunlight. Given Sing Buri's agrarian economy, unused or less productive paddy fields could potentially be converted into solar farms.
Also worth considering are rooftop installations on large industrial buildings in nearby industrial parks such as those in Ayutthaya province. These can provide substantial area for installation without additional land requirements.
However, any decision on installing large-scale solar PV should also take into account other factors such as proximity to power grids for easy transmission, environmental impact assessments and local regulations regarding renewable energy 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.
