Solar PV Analysis of Akat Amnuai, Thailand
The location at Akat Amnuai, Sakon Nakhon, Thailand is pretty good for generating energy through solar PV panels all year round. This is because it's situated in the Tropics where sunlight is fairly consistent throughout most of the year. The seasons here are usually marked more by wet and dry periods rather than significant changes in temperature or daylight hours.
Based on the data given, each kilowatt of installed solar can generate between 5.41 to 5.99 kilowatt-hours per day depending on the season - with Spring being slightly better compared to other seasons. However, these differences across seasons aren't very large which means that solar power generation should be quite stable throughout the year.
For a fixed panel installation at this location, tilting panels at an angle of 17 degrees South would help maximize total annual production from solar PV systems.
As for potential obstacles to solar production at this location, they could include things like heavy rainfall during wet seasons which might reduce sunlight exposure and therefore electricity generation from your panels. Dust or other airborne particles settling on your panels could also decrease their efficiency over time if not cleaned regularly.
To mitigate these issues, you might want to consider installing a system that allows you to adjust the tilt angle of your panels based on seasonal variations in sun path so as to optimize their exposure to sunlight even during less sunny periods (like rainy season). Regular cleaning and maintenance of your panels would also help ensure they're operating efficiently and producing as much electricity as possible despite any dust or debris accumulation.
In conclusion, while there may be some minor challenges associated with generating solar energy in Akat Amnuai due mainly to its tropical climate (i.e., heavy rains), these can generally be managed effectively through appropriate design considerations and regular maintenance practices thereby making it a suitable place for harnessing solar power 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 Akat Amnuai
Seasonal solar PV output for Latitude: 17.434, Longitude: 103.6615 (Akat Amnuai, 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 17° South in Akat Amnuai, Thailand
To maximize your solar PV system's energy output in Akat Amnuai, Thailand (Lat/Long 17.434, 103.6615) throughout the year, you should tilt your panels at an angle of 17° 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 Akat Amnuai, 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 Akat Amnuai, Thailand. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 17° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 1° South in Summer | 24° South in Autumn | 33° South in Winter | 11° 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 Akat Amnuai, 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 Akat Amnuai, 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 Akat Amnuai, Thailand
Akat Amnuai is located in the Sakon Nakhon province of Thailand. The region is largely flat with some small hills, perfect for farming activities which are predominant in this area. It has a tropical climate with high temperatures and humidity levels throughout the year.
For large-scale solar PV installations, open and flat terrains are typically preferred as they allow for easier installation and maintenance, as well as optimal exposure to sunlight. Given Akat Amnuai's topography, the vast agricultural lands surrounding it could potentially be suitable for such installations.
However, it's important to note that turning agricultural land into a solar farm might have implications on food security or local livelihoods. In such cases, brownfield sites (abandoned or underused industrial areas) could be an alternative option if available.
Also noteworthy is that Sakon Nakhon province has several reservoirs like the Nam Un Dam and Nong Han Lake; floating solar PV systems could be another viable option here if conditions permit.
Ultimately though, feasibility would depend on a detailed site assessment considering factors like land availability & use restrictions, solar irradiation levels (which seem promising given its tropical location), grid connectivity options etc.
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.
