Khlong Khlung, Kamphaeng Phet, Thailand, situated at latitude 16.2016 and longitude 99.7205, presents a favorable location for solar energy production 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 panel efficiency in Khlong Khlung demonstrates impressive year-round performance. Spring emerges as the most productive season, with an average daily output of 6.11 kWh per kW of installed solar capacity. Winter follows closely behind at 5.72 kWh/day, while summer yields 5.48 kWh/day. Autumn, though slightly less productive, still maintains a robust 4.91 kWh/day. These figures indicate that Khlong Khlung is an excellent location for solar energy generation, with relatively consistent output across all seasons. The minimal fluctuation between seasons suggests that solar installations in this area can provide reliable energy production throughout the year.

Optimal Panel Tilt

For fixed solar panel installations in Khlong Khlung, Kamphaeng Phet, the ideal tilt angle to maximize year-round energy production is 16 degrees facing South. This angle has been calculated taking into account the location's latitude, the Earth's elliptical orbit, and daily solar elevation angles, weighted by NASA's solar irradiance data.

Environmental Considerations

While Khlong Khlung offers favorable conditions for 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 potentially reduce solar output due to cloud cover and rainfall. 2. Dust and debris: During the dry season, dust accumulation on panels may occur, potentially impacting efficiency. To mitigate these factors, consider the following preventative measures:

• Install a reliable cleaning system or schedule regular manual cleaning to combat dust accumulation.
• Use high-quality, weather-resistant panels that can withstand heavy rainfall and humidity.
• Implement a slight increase in panel tilt during the rainy season to aid in natural cleaning by rainwater.

By addressing these considerations, solar installations in Khlong Khlung can maintain optimal performance and capitalize on the location's excellent solar potential 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 Khlong Khlung

Seasonal solar PV output for Latitude: 16.2016, Longitude: 99.7205 (Khlong Khlung, 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 Khlong Khlung, Thailand

To maximize your solar PV system's energy output in Khlong Khlung, Thailand (Lat/Long 16.2016, 99.7205) 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 Khlong Khlung, 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 Khlong Khlung, 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	22° South in Autumn	32° South in Winter	9° 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 Khlong Khlung, 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 Khlong Khlung, 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 Khlong Khlung, Thailand

The area around Khlong Khlung, Thailand, is characterized by a mix of gently rolling terrain and flat lowlands. This region is part of the central plains of Thailand, which gradually transition into more hilly areas as you move westward towards the border with Myanmar.

The immediate vicinity of Khlong Khlung features mostly flat to slightly undulating landscapes, with occasional low hills and small valleys. The area is primarily agricultural, with rice paddies and other crop fields dominating the landscape. Numerous small streams and irrigation canals crisscross the region, supporting the local farming activities.

As you move further from the town center, the terrain becomes slightly more varied. To the east, the land remains predominantly flat, extending towards the Chao Phraya River basin. To the west, the topography becomes more undulating, with scattered hills and elevated areas as you approach the foothills of the Dawna Range.

For large-scale solar PV installations, the most suitable areas would be the flat, open spaces to the east and southeast of Khlong Khlung. These areas offer several advantages for solar energy development:

1. Abundant flat land with minimal shading from natural features or buildings
2. Good sun exposure throughout the year due to the region's tropical climate
3. Proximity to existing infrastructure, including roads and power transmission lines
4. Less competition for land use compared to the more densely populated areas closer to major cities

The gently sloping areas to the west could also be considered for solar installations, but they may require more extensive site preparation and might not be as cost-effective as the flatter regions to the east. Additionally, care should be taken to avoid areas prone to flooding or those with high agricultural value to minimize environmental and economic impacts.

It's important to note that while the topography is generally favorable for solar PV development, other factors such as local regulations, land ownership, and environmental considerations would need to be carefully evaluated before proceeding with any large-scale solar projects in the region.
