The consistent output across seasons suggests that solar installations in this area can provide reliable power throughout the year, with only minor fluctuations.

Optimal Panel Positioning

For fixed solar panel installations in Ban Nong Laeng, Surin, the ideal tilt angle to maximize year-round energy production is 14 degrees facing South. This angle has been calculated taking into account the location's latitude, daily solar elevation angles, and potential daily PV output based on NASA's solar irradiance data.

Environmental Considerations

While Ban Nong Laeng's tropical climate is generally conducive to solar energy production, there are some environmental factors to consider: 1. Rainfall: The region experiences a wet season, which could temporarily reduce solar output due to cloud cover. 2. Dust and debris: During the dry season, dust accumulation on panels may affect efficiency. To mitigate these issues, consider implementing regular cleaning schedules for the panels, especially during the dry season. Additionally, installing panels at the recommended 14-degree tilt can help with natural cleaning during rainfall events.

Conclusion

Overall, Ban Nong Laeng offers an ideal location for solar PV installations. The consistent year-round sunlight and relatively stable energy production across seasons make it a prime spot for solar energy harvesting. With proper installation and maintenance, solar panels in this area can provide a reliable and sustainable source of energy throughout the year.

Solar output per kW of installed solar PV by season in Ban Nong Laeng

Seasonal solar PV output for Latitude: 15.0202, Longitude: 103.9332 (Ban Nong Laeng, 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 Ban Nong Laeng, Thailand

To maximize your solar PV system's energy output in Ban Nong Laeng, Thailand (Lat/Long 15.0202, 103.9332) 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 Ban Nong Laeng, 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 Ban Nong Laeng, 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 Ban Nong Laeng, 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 Ban Nong Laeng, Thailand.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Ban Nong Laeng, Thailand

The topography around Ban Nong Laeng, Thailand, located at coordinates 15.0202 latitude and 103.9332 longitude, is characterized by a mix of gently rolling terrain and flat lowlands. This area is situated in the northeastern region of Thailand, known as Isan, which is primarily a large plateau with occasional low hills and shallow valleys. The landscape surrounding Ban Nong Laeng is predominantly rural, with expansive agricultural fields interspersed with patches of deciduous forests. The terrain is generally flat to slightly undulating, with elevations ranging from approximately 150 to 200 meters above sea level. This relatively level topography is a result of the area's geological history, having once been part of an ancient sea bed that has since been filled with sedimentary deposits. Several small streams and irrigation canals crisscross the region, providing water for the mainly rice-based agriculture that dominates the local economy. These waterways have contributed to the formation of subtle variations in the landscape, creating shallow depressions and gentle slopes throughout the area.

Suitability for Large-Scale Solar PV

The topographical features of the area surrounding Ban Nong Laeng make it potentially suitable for large-scale solar photovoltaic (PV) installations. The most appropriate locations for such projects would be the extensive flat or gently sloping agricultural lands that are abundant in the region. These open areas offer several advantages for solar PV development: Firstly, the relatively level terrain reduces the need for extensive land preparation, minimizing construction costs and environmental impact. The absence of significant geographical obstacles also allows for efficient layout and arrangement of solar panels, maximizing energy capture. Secondly, the rural nature of the region means there are large, contiguous plots of land available, which is crucial for utility-scale solar installations. These areas are often already cleared for agriculture, reducing the need for deforestation or major land-use changes. Thirdly, the region experiences ample sunlight throughout the year, with relatively few cloudy days, making it ideal for solar energy generation. The lack of tall structures or geographical features that could cast shadows on the panels further enhances the area's suitability. However, it's important to note that while the topography is favorable, other factors such as grid connectivity, local regulations, and environmental considerations would need to be carefully assessed before implementing any large-scale solar PV projects in the area. Additionally, care should be taken to balance solar development with the region's agricultural needs, potentially exploring dual-use strategies that allow for both solar energy production and farming activities on the same land.

Thailand solar PV Stats as a country
