Solar PV Analysis of Warichaphum, Thailand
Warichaphum, Sakon Nakhon, Thailand is a very suitable location for generating solar energy all year round. This is because it's located in the tropics where sunlight is consistent throughout most of the year. The amount of electricity that can be produced from each kilowatt of installed solar power varies slightly by season but remains relatively high: 5.86kWh/day in Summer, 5.41kWh/day in Autumn, 5.90kWh/day in Winter, and 5.99kWh/day in Spring.
This means that you can expect to generate a good amount of electricity from your solar panels no matter what time of year it is. However, spring and winter are slightly better seasons for generating solar power at this location due to higher daily output.
In terms of panel installation, tilting them at an angle of 17 degrees facing south would maximize their exposure to sunlight and hence increase total yearly production from the solar panels.
However, there could be certain local factors that might affect the efficiency of your solar panels here. For instance, during monsoon season (usually between May and October), heavy rains or cloud cover might reduce sunlight exposure on some days which could lower your daily output somewhat during these months.
To mitigate this issue as much as possible when installing your system:
1) You should consider using high-quality panels with excellent performance even under less-than-ideal light conditions.
2) Regular maintenance like cleaning off any dust or debris accumulated on the surface will help keep them performing optimally.
3) If possible install some form of movable covering mechanism which can protect them during extreme weather conditions without blocking out too much sunlight on regular days.
4) Finally using advanced inverters or battery storage systems will ensure any excess energy generated on sunny days isn't wasted but stored for use when needed later.
Overall though given its tropical climate with abundant sunshine throughout most parts of the year Warichaphum would generally make for an excellent location to harness solar energy.
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 Warichaphum
Seasonal solar PV output for Latitude: 17.2809, Longitude: 103.633 (Warichaphum, 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 Warichaphum, Thailand
To maximize your solar PV system's energy output in Warichaphum, Thailand (Lat/Long 17.2809, 103.633) 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 Warichaphum, 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 Warichaphum, 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 | 10° 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 Warichaphum, 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 Warichaphum, 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 Warichaphum, Thailand
Warichaphum is located in the Sakon Nakhon province of Thailand. The topography around this area is relatively flat with some undulating hills. It's characterized by agricultural lands, forests, and a few water bodies.
The flat areas are ideal for large-scale solar PV installations due to their ease of installation and maintenance. Agricultural lands could also be considered for dual-use solar farming where crops are grown underneath solar panels. However, this would require an agreement with local farmers and may have implications on the type of crops that can be grown.
Additionally, areas near water bodies might also be suitable as they often have less shading issues which is beneficial for solar power generation. But it's important to consider potential environmental impacts before setting up large-scale installations in such locations.
Lastly, deforested or degraded land could also serve as potential sites for large scale solar PV systems since these lands are often underutilized and installing a renewable energy source there could contribute positively towards land rehabilitation efforts.
However, any decision should take into account factors like sunlight availability (solar irradiance), accessibility to transmission lines or grid connection points, current land use patterns 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.
