The location of Tadagyi, Shan State, Myanmar, situated at 21.0333 latitude and 96.6898 longitude, presents a favorable environment for solar PV energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasons primarily characterized by wet and dry periods rather than significant temperature variations.

Seasonal Solar Output

Solar energy production in Tadagyi demonstrates a relatively stable pattern across seasons, with a notable peak during spring. The expected daily electricity output per kilowatt of installed solar capacity for each season is as follows: • Spring: 6.41 kWh/day • Winter: 5.24 kWh/day • Summer: 5.23 kWh/day • Autumn: 4.98 kWh/day Spring emerges as the most productive season, likely due to clearer skies and moderate temperatures. The other seasons maintain a fairly consistent output, with autumn showing a slight dip but still providing substantial energy generation.

Optimal Panel Placement

For fixed solar panel installations in Tadagyi, Shan State, the ideal tilt angle to maximize year-round energy production is 20 degrees facing South. This angle has been calculated considering the location's latitude, daily solar elevation angles, and weighted by NASA's solar irradiance data to account for the Earth's elliptical orbit.

Environmental Considerations

While Tadagyi's location is generally favorable for solar energy production, there are a few environmental factors to consider: 1. Monsoon season: Myanmar experiences a monsoon climate, which could lead to increased cloud cover and rainfall during certain months, potentially reducing solar output. To mitigate this, ensure panels are installed with proper drainage and use high-quality, water-resistant equipment. 2. Dust and pollution: Agricultural activities and urban development in the region may contribute to air pollution and dust accumulation on solar panels. Regular cleaning and maintenance of the panels can help maintain optimal efficiency. 3. Temperature: High temperatures in tropical regions can slightly reduce solar panel efficiency. Using panels with good heat dissipation properties and ensuring proper ventilation during installation can help address this issue. By taking these factors into account and implementing appropriate preventative measures, solar PV installations in Tadagyi can maximize their energy production potential throughout the year.

Ideally tilt fixed solar panels 20° South in Tadagyi, Myanmar

To maximize your solar PV system's energy output in Tadagyi, Myanmar (Lat/Long 21.0333, 96.6898) throughout the year, you should tilt your panels at an angle of 20° 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 Tadagyi, Myanmar

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 Tadagyi, Myanmar. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 20° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
5° South in Summer	27° South in Autumn	36° South in Winter	14° 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 Tadagyi, Myanmar

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 Tadagyi, Myanmar.

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 Tadagyi, Myanmar

The topography around Tadagyi, Myanmar, is characterized by diverse and varied terrain. This region, situated in the central part of the country, features a mix of gently rolling hills, flat plains, and some more rugged areas. The landscape is primarily dominated by agricultural land, interspersed with patches of forest and scattered settlements. To the west of Tadagyi, the terrain gradually slopes towards the Irrawaddy River, one of Myanmar's major waterways. This area is predominantly flat, with rich alluvial soil that supports extensive agricultural activities. As one moves eastward from Tadagyi, the landscape becomes more undulating, with low hills and small valleys creating a patchwork of farmland and natural vegetation. The region experiences a tropical savanna climate, with distinct wet and dry seasons. This climate, combined with the varied topography, has shaped the natural vegetation, which includes deciduous forests, grasslands, and shrublands. However, much of the original vegetation has been cleared for agriculture, particularly rice cultivation, which is a major economic activity in the area.

Suitability for Large-Scale Solar PV

When considering areas nearby Tadagyi for large-scale solar photovoltaic (PV) installations, several factors come into play. The most suitable locations would be those that offer a combination of favorable topography, ample sunlight exposure, and minimal environmental impact. The flat plains to the west of Tadagyi, stretching towards the Irrawaddy River, present promising opportunities for solar PV development. These areas benefit from their relatively level terrain, which simplifies construction and maintenance of solar arrays. Additionally, the open landscape ensures minimal shading from natural features, maximizing sunlight exposure throughout the day. Some of the gently rolling hills to the east and southeast of Tadagyi could also be suitable for solar PV installations. While these areas may require some terrain modification, they often receive excellent sun exposure due to their elevated positions. However, care must be taken to avoid areas with steep slopes or dense vegetation, as these could increase installation costs and environmental impact. It's important to note that while agricultural land might seem ideal for solar PV due to its flat nature, converting productive farmland to solar farms could have socio-economic implications. Therefore, the most suitable areas would likely be those that are currently underutilized or degraded, where solar installations could provide economic benefits without significantly impacting food production or natural habitats. Lastly, proximity to existing infrastructure, such as roads and power transmission lines, should be considered when selecting sites for large-scale solar PV. Areas closer to Tadagyi or other nearby towns might offer advantages in terms of grid connection and accessibility, potentially reducing overall project costs and improving feasibility.
