Ang Thong, Thailand, situated at latitude 14.589 and longitude 100.4514, offers a promising location for solar energy generation throughout the year. This tropical setting benefits from consistent sunlight, with seasons primarily distinguished by wet and dry periods rather than significant temperature variations.

Seasonal Solar Performance

Solar photovoltaic (PV) systems in Ang Thong demonstrate robust performance across all seasons. Spring yields the highest output at 6.03 kWh per day for each kilowatt of installed capacity. Summer and winter follow closely, producing 5.91 kWh/day and 5.88 kWh/day, respectively. Autumn sees a slight dip but still maintains a respectable 5.01 kWh/day. The minimal fluctuation between seasons indicates that Ang Thong is an excellent location for year-round solar energy production. The consistent output throughout the year ensures a steady supply of renewable energy, making it an ideal choice for both residential and commercial applications.

Optimal Panel Positioning

To maximize energy harvest, fixed solar panels in Ang Thong should be tilted at a 14-degree angle facing south. This optimal tilt takes into account the location's latitude, the sun's position throughout the year, and the Earth's elliptical orbit. By adhering to this angle, solar installations can capture the maximum amount of sunlight across all seasons, enhancing overall system efficiency.

Environmental Considerations

While Ang Thong's climate is generally favorable for solar energy production, there are a few environmental factors to consider: 1. Monsoon season: The region experiences a monsoon season, typically from May to October, which can bring increased cloud cover and rainfall. This may temporarily reduce solar output. 2. Dust and pollution: As with many tropical areas, dust accumulation on panels can be a concern, potentially decreasing efficiency over time. To mitigate these factors, consider implementing the following measures: 1. Regular cleaning: Establish a routine cleaning schedule for solar panels to remove dust and debris, especially during the dry season. 2. Weather-resistant equipment: Use high-quality, weather-resistant solar panels and mounting systems designed to withstand tropical conditions. 3. Slight over-sizing: Consider slightly over-sizing the solar system to compensate for potential reduced output during the monsoon season. By addressing these environmental factors and optimizing panel placement, solar installations in Ang Thong can harness the abundant tropical sunlight effectively, providing a reliable and sustainable energy source 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 Ang Thong

Seasonal solar PV output for Latitude: 14.589, Longitude: 100.4514 (Ang 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 14° South in Ang Thong, Thailand

To maximize your solar PV system's energy output in Ang Thong, Thailand (Lat/Long 14.589, 100.4514) 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 Ang 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 Ang Thong, 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
2° 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 Ang 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 Ang Thong, 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 Ang Thong, Thailand

The topography around Ang Thong, Thailand, is characterized by a predominantly flat landscape. This area is part of the central plains of Thailand, which is known for its low-lying, alluvial terrain. The region is primarily composed of fertile agricultural land, with rice paddies and other crop fields stretching across the horizon.

The Chao Phraya River, one of Thailand's major waterways, flows through this region, contributing to the flat nature of the landscape. The river and its tributaries have, over time, deposited rich sediments across the area, creating a vast floodplain. This has resulted in a relatively uniform elevation throughout much of the surrounding territory.

While the immediate vicinity of Ang Thong is predominantly flat, there are some gentle undulations and slight variations in elevation as you move further from the city. However, these are generally subtle and do not significantly alter the overall flat character of the landscape.

Areas Suitable for Large-Scale Solar PV

Given the topography of the region, there are several areas nearby that would be well-suited for large-scale solar photovoltaic (PV) installations:

1. Agricultural lands: The extensive flat agricultural areas surrounding Ang Thong provide ideal conditions for solar farms. These open spaces receive ample sunlight and have minimal shading issues, making them prime candidates for solar PV installations.

2. Fallow or unused fields: Any fallow or unused agricultural land in the vicinity would be particularly suitable, as it would not compete with active food production.

3. Industrial zones: If there are any industrial zones or brownfield sites in the area, these could be repurposed for solar energy production, taking advantage of existing infrastructure and minimizing impact on greenfield sites.

4. Areas adjacent to existing power infrastructure: Locations near power substations or transmission lines would be advantageous for easy grid connection, reducing the cost and complexity of integrating the solar power into the existing electricity network.

5. Elevated areas: While not abundant in this region, any slightly elevated areas or gentle slopes facing south would be ideal for maximizing solar exposure throughout the day.

It's important to note that while the flat terrain is generally favorable for solar PV, considerations such as flood risk, soil stability, and environmental impact would need to be carefully assessed before implementing any large-scale solar projects in the region.
