The location at Bang Bua Thong, Nonthaburi, Thailand is quite suitable for generating energy through solar photovoltaic (PV) systems throughout the year. This is because it's located in the Tropics where sunlight is fairly consistent all year round.
In simple terms, a solar PV system converts sunlight into electricity. The amount of electricity you can generate depends on how much sunlight hits your solar panels. In Bang Bua Thong, Nonthaburi, you can expect to produce around 5-6 kilowatt-hours (kWh) of electricity per day for each kilowatt (kW) of solar panels installed.
This output varies slightly by season:
- Summer: around 5.91 kWh/day
- Autumn: about 5.02 kWh/day
- Winter: roughly 5.97 kWh/day
- Spring: approximately 6.05 kWh/day
These numbers indicate that spring and summer are slightly better times for solar energy production in this area due to higher sunlight availability.
To get the most out of your solar PV system in Bang Bua Thong, Nonthaburi, you should ideally tilt your panels at an angle of 13 degrees facing southward - this maximises their exposure to the sun over the course of a year.
However, there might be some local factors that could affect your system's performance:
1) Rainy or Monsoon Season - During periods with heavy rain or monsoon weather conditions common in tropical areas like Thailand, less sunshine reaches the ground which may reduce power generation from your PV system.
2) Dust and Debris - If dust or other debris settles on your panels they can block sunlight and lower their efficiency.
Preventative measures include:
1) Weather-proofing equipment against heavy rains.
2) Regular maintenance and cleaning schedules to remove any dust or debris from panel surfaces.
3) Installing adjustable mountings so that panel angles can be changed according to seasons if needed.
Overall though, Bang Bua Thong is a good location for solar energy generation 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 Bang Bua Thong
Seasonal solar PV output for Latitude: 13.92, Longitude: 100.4247 (Bang Bua Thong, 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 Bang Bua Thong, Thailand
To maximize your solar PV system's energy output in Bang Bua Thong, Thailand (Lat/Long 13.92, 100.4247) 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 Bang Bua Thong, 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 Bang Bua Thong, 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 Bang Bua Thong, 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 Bang Bua Thong, 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 Bang Bua Thong, Thailand
Bang Bua Thong is a district located in the Nonthaburi Province of Thailand, just north of Bangkok. The topography in this region is relatively flat, as it's part of the Chao Phraya River plain. This area has an average elevation of around 2 meters above sea level.
The climate here is tropical and humid, with a significant amount of rainfall throughout the year but also plenty of sunshine, particularly during the dry season from November to April.
For large-scale solar PV installations, areas with flat terrain and high levels of sunlight are ideal. Given these conditions, agricultural lands or other open spaces in and around Bang Bua Thong could be potentially suitable for such projects. However, any plans would need to consider environmental impacts and potential land use conflicts.
In terms of specific locations nearby that might be suited for large-scale solar PV:
1) Areas towards east along Highway 345 have relatively less dense population which might provide larger tracts for setting up Solar Farms.
2) North-eastern part towards Pathum Thani province might also provide opportunities due to its proximity to industrial areas where power demand could be higher.
It should be noted that detailed feasibility studies including aspects like grid connectivity and infrastructure availability would need to be carried out before finalizing any location.
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.
