Bayanterem, Sühbaatar Aymag, Mongolia, located at latitude 47.1333 and longitude 112.3833 in the Northern Temperate Zone, presents a mixed picture for solar PV energy generation throughout the year. The location experiences significant seasonal variations in solar energy production, which impacts its overall suitability for year-round solar power generation.

Seasonal Solar Energy Production

The solar energy output at Bayanterem varies considerably across the four meteorological seasons:

• Summer: 6.27 kWh/day per kW installed
• Spring: 6.03 kWh/day per kW installed
• Autumn: 3.53 kWh/day per kW installed
• Winter: 2.46 kWh/day per kW installed

Summer and spring are clearly the most productive seasons for solar energy generation in Bayanterem. During these months, the longer daylight hours and higher sun angles contribute to increased solar panel efficiency.

Optimal Panel Tilt Angle

For fixed panel installations in Bayanterem, Sühbaatar Aymag, the ideal tilt angle to maximize year-round solar production is 42 degrees facing south. This angle takes into account the location's latitude and the Earth's elliptical orbit, optimizing energy capture across all seasons.

Challenges and Considerations

While Bayanterem has good potential for solar energy production, particularly in summer and spring, there are some factors that could impede solar production: 1. Harsh winters: Mongolia is known for its severe winters, which can lead to snow accumulation on solar panels, reducing their efficiency. To mitigate this, panels can be installed at a steeper angle to promote snow sliding off, and regular maintenance may be necessary. 2. Dust storms: Mongolia occasionally experiences dust storms, which can coat solar panels and decrease their efficiency. Installing panels with self-cleaning technologies or implementing regular cleaning routines can help maintain optimal performance. 3. Temperature extremes: The region experiences both very cold winters and hot summers, which can affect solar panel efficiency. Choosing high-quality panels designed to perform well in extreme temperatures is crucial.

Despite these challenges, with proper planning and maintenance, Bayanterem can be a viable location for solar PV installations, particularly those designed to capitalize on the high production periods during summer and spring.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 5 locations across Mongolia. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Bayanterem

Seasonal solar PV output for Latitude: 47.1333, Longitude: 112.3833 (Bayanterem, Mongolia), 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 42° South in Bayanterem, Mongolia

To maximize your solar PV system's energy output in Bayanterem, Mongolia (Lat/Long 47.1333, 112.3833) throughout the year, you should tilt your panels at an angle of 42° 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 Bayanterem, Mongolia

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 Bayanterem, Mongolia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 42° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
30° South in Summer	51° South in Autumn	61° South in Winter	40° 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 Bayanterem, Mongolia

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 Bayanterem, Mongolia.

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 Bayanterem, Mongolia

The topography around Bayanterem, Mongolia, located at approximately 47.1333 degrees north latitude and 112.3833 degrees east longitude, is characterized by a diverse landscape typical of the Mongolian steppe. This region is part of the vast Central Asian grasslands, featuring gently rolling hills and wide-open plains that stretch as far as the eye can see. The terrain in this area is predominantly flat to slightly undulating, with occasional low hills and shallow valleys. The elevation of Bayanterem and its surrounding areas is generally between 1,000 to 1,500 meters above sea level, contributing to its continental climate with extreme temperature variations between seasons. Vegetation in the region is sparse, consisting mainly of hardy grasses and small shrubs adapted to the semi-arid conditions. Trees are scarce, typically found only near water sources or in protected valleys. This lack of tall vegetation means there are few natural obstacles to block sunlight or wind.

Suitability for Large-Scale Solar PV

The areas surrounding Bayanterem offer several favorable conditions for large-scale solar photovoltaic (PV) installations. The most suitable locations for such projects would be the expansive, flat plains that dominate the landscape. These areas provide ideal conditions for solar energy capture due to their unobstructed exposure to sunlight throughout the day. Specifically, the gently sloping areas to the south and southeast of Bayanterem would be particularly well-suited for solar PV installations. These locations would benefit from optimal sun angles, especially during the winter months when solar irradiance is lower. The slight inclination of these areas can also aid in natural cooling of solar panels, improving their efficiency. Another advantage of this region for solar energy development is the relatively low population density. This means that large tracts of land could potentially be available for solar farms without significant conflicts with other land uses or settlements. However, it's important to note that while the topography is favorable, other factors such as grid connectivity, access to water for panel cleaning, and local environmental considerations would need to be carefully assessed before embarking on any large-scale solar project in this area.
