Ideally tilt fixed solar panels 14° South in Changwat Sara Buri, Thailand

To maximize your solar PV system's energy output in Changwat Sara Buri, Thailand (Lat/Long 14.5476, 100.8977) 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 Changwat Sara Buri, 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 Changwat Sara Buri, 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.

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 Changwat Sara Buri, Thailand

The topography around Changwat Sara Buri, Thailand, is characterized by a mix of flat plains and gently rolling hills. This region, located in central Thailand, is part of the larger Chao Phraya River basin. The landscape is predominantly composed of low-lying areas with occasional elevations, creating a diverse terrain that supports various agricultural activities and urban development. The plains in this area are expansive and relatively flat, making them ideal for rice cultivation and other farming practices. These lowlands are interspersed with small rivers and streams that contribute to the region's fertility. As one moves away from the central plains, the terrain gradually becomes more undulating, with gentle slopes and low hills dotting the landscape. To the east of Sara Buri, the topography becomes slightly more varied, with some areas featuring limestone outcrops and small mountain ranges. These elevated areas provide a stark contrast to the surrounding flatlands and offer scenic views of the region. Despite these occasional rises in elevation, the overall topography remains largely accessible and suitable for various types of development.

Suitability for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The flat plains surrounding Sara Buri present excellent opportunities for solar energy development. These areas offer vast, unobstructed spaces that receive ample sunlight throughout the year, making them ideal for large solar arrays. The gently rolling hills to the east of Sara Buri could also be suitable for solar PV installations. These slightly elevated areas may benefit from reduced shading and potentially higher exposure to sunlight. However, developers would need to carefully assess the impact of the terrain on construction costs and panel efficiency. Areas to the north and west of Sara Buri, where the landscape remains predominantly flat, would be particularly well-suited for large-scale solar projects. These regions offer the advantage of easier construction and maintenance access, as well as the potential for expansive solar farms without significant topographical obstacles. It's important to note that while the topography is favorable for solar PV development, other factors such as proximity to power infrastructure, land availability, and environmental considerations would also play crucial roles in determining the most suitable locations for large-scale solar projects in the vicinity of Sara Buri.
