Yang Talat, Kalasin, Thailand, located at 16.4006° N, 103.3869° E, presents a highly favorable environment for solar energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasonal variations primarily characterized by wet and dry periods rather than significant changes in daylight duration.

Year-round Solar Performance

The solar energy potential in Yang Talat remains remarkably stable across all seasons. Spring sees the highest average daily output at 5.95 kWh per kW of installed solar capacity, closely followed by summer at 5.92 kWh/day and winter at 5.90 kWh/day. Even during autumn, when output slightly dips to 5.18 kWh/day, the performance remains strong. This consistent year-round performance makes Yang Talat an excellent location for solar PV installations. The minimal variation between seasons ensures a reliable energy supply throughout the year, with only a slight decrease during the autumn months.

Optimal Panel Positioning

For fixed solar panel installations in Yang Talat, Kalasin, the ideal tilt angle to maximize year-round energy production is 16 degrees facing South. This angle has been calculated to optimize solar capture across all seasons, taking into account the location's latitude and the sun's position throughout the year.

Environmental Considerations

While Yang Talat's tropical climate is generally conducive to solar energy production, there are some environmental factors to consider: 1. Rainfall: The region experiences a monsoon season, typically from May to October, which could temporarily reduce solar output due to cloud cover. 2. Dust and debris: During dry seasons, dust accumulation on panels may slightly decrease efficiency. To mitigate these factors, consider the following preventative measures:

• Install panels at the recommended 16-degree tilt to facilitate natural cleaning during rainfall
• Implement a regular cleaning schedule, especially during dry periods
• Use quality, weather-resistant solar panels designed for tropical climates
• Consider a ground-mounted system for easier maintenance access

Overall, Yang Talat's location offers excellent conditions for solar energy production. With proper installation and maintenance, a solar PV system in this area can provide consistent and efficient energy output throughout the year.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Solar output per kW of installed solar PV by season in Yang Talat

Seasonal solar PV output for Latitude: 16.4006, Longitude: 103.3869 (Yang Talat, 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 16° South in Yang Talat, Thailand

To maximize your solar PV system's energy output in Yang Talat, Thailand (Lat/Long 16.4006, 103.3869) throughout the year, you should tilt your panels at an angle of 16° 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 Yang Talat, 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 Yang Talat, Thailand. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 16° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
0° in Summer	23° South in Autumn	32° 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 Yang Talat, 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 Yang Talat, 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 Yang Talat, Thailand

The area around Yang Talat, Thailand, is characterized by a relatively flat landscape typical of the Isan region in northeastern Thailand. This part of the country is known for its gently rolling plains and low-lying terrain, with few significant hills or mountains. The topography is largely shaped by the Mun River system, which is a major tributary of the Mekong River.

The land in and around Yang Talat is predominantly used for agriculture, particularly rice cultivation. You'll find expansive rice paddies stretching across the horizon, interspersed with small patches of woodland and occasional water bodies. The region experiences a tropical savanna climate, with distinct wet and dry seasons, which influences the local vegetation and land use patterns.

As for areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, several factors make this region potentially favorable:

1. The flat terrain of the Isan plateau provides ample space for solar panel arrays without the need for extensive land modification.
2. The region receives abundant sunshine throughout the year, especially during the dry season, which is ideal for solar energy generation.
3. Agricultural areas that are less productive or fallow lands could potentially be repurposed for solar farms without significantly impacting food production.

Specifically, areas to the east and northeast of Yang Talat, where the terrain remains consistently flat and open, might be particularly well-suited for large-scale solar PV projects. These locations would likely offer minimal shading from natural features and good access to existing infrastructure.

However, it's important to note that any large-scale solar development would need to consider factors beyond just topography, such as proximity to power grids, local land use regulations, and environmental impact assessments. Additionally, care should be taken to balance renewable energy development with the preservation of agricultural land, which is vital to the local economy and food security in the region.
