Solar Energy Potential in Choibalsan, East Aimak, Mongolia

Choibalsan, East Aimak, Mongolia, located at 48.0707° N, 114.5316° E, presents a varied landscape for solar energy generation throughout the year. This northern temperate zone location experiences significant seasonal fluctuations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems.

Seasonal Solar Production

The solar energy potential in Choibalsan varies dramatically across the four seasons. Summer stands out as the most productive period, with an impressive 6.29 kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind, generating 5.85 kWh/day/kW. These warmer months offer ideal conditions for maximizing solar energy production. However, the colder seasons see a substantial drop in energy output. Autumn yields a moderate 3.40 kWh/day/kW, while winter experiences a significant decline to just 1.96 kWh/day/kW. This stark contrast highlights the challenges of maintaining consistent energy production year-round in Choibalsan's climate.

Optimizing Solar Panel Installation

To maximize year-round solar energy production in Choibalsan, East Aimak, fixed solar panels should be installed at a tilt angle of 42 degrees facing south. This optimal angle takes into account the region's latitude and seasonal sun positions, ensuring the best possible exposure to sunlight throughout the year.

Environmental and Weather Considerations

Choibalsan's location presents some challenges for solar energy production:

• Extreme temperature fluctuations: The region experiences very cold winters and hot summers, which can affect solar panel efficiency.
• Dust storms: Mongolia is prone to dust storms, which can reduce panel performance by blocking sunlight.

To mitigate these issues, consider the following preventative measures: 1. Use high-quality, temperature-resistant solar panels designed for extreme climates. 2. Implement a regular cleaning schedule to remove dust and debris from panel surfaces. 3. Install wind barriers or protective structures to shield panels from dust storms. 4. Employ snow-shedding technologies for winter months to prevent snow accumulation on panels. While Choibalsan's location presents challenges for year-round solar energy production, proper planning and maintenance can help maximize the potential of solar PV systems in this unique environment.

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 Choibalsan

Seasonal solar PV output for Latitude: 48.0707, Longitude: 114.5316 (Choibalsan, 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 Choibalsan, Mongolia

To maximize your solar PV system's energy output in Choibalsan, Mongolia (Lat/Long 48.0707, 114.5316) 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 Choibalsan, 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 Choibalsan, 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
32° South in Summer	52° South in Autumn	62° South in Winter	41° 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 Choibalsan, 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 Choibalsan, 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 Choibalsan, Mongolia

The topography around Choibalsan, Mongolia, is characterized by vast, open steppes and gently rolling plains. This region, located in the eastern part of the country, is part of the larger Mongolian-Manchurian grassland ecosystem. The landscape is predominantly flat to slightly undulating, with occasional low hills and shallow valleys.

The Kherlen River, one of Mongolia's major waterways, flows through the area near Choibalsan, creating a narrow strip of more lush vegetation along its banks. This river valley contrasts with the surrounding drier grasslands and provides an important water source for the region.

To the north and east of Choibalsan, the terrain gradually transitions into the southern edges of the Khentii Mountains, where the landscape becomes more rugged and elevated. However, the immediate vicinity of Choibalsan remains relatively level, making it suitable for various land uses.

Regarding areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, the expansive, open plains surrounding Choibalsan offer several advantages. The flat or gently sloping terrain to the south and west of the city would be particularly well-suited for solar farms. These areas benefit from minimal shadowing effects and allow for easy construction and maintenance of solar panels.

The region's climate, characterized by long, sunny days during the summer months and relatively low precipitation, further enhances its suitability for solar energy production. The lack of dense vegetation or forests in these steppe areas means there would be minimal land clearing required for solar farm development.

It's worth noting that while the areas immediately adjacent to the Kherlen River might seem attractive due to their accessibility, they may not be ideal for large-scale solar installations. These riverside zones are often more valuable for agriculture and may have higher biodiversity, making them less suitable for industrial-scale development.

In conclusion, the vast, open grasslands to the south and west of Choibalsan, away from the river valley but still within reasonable distance of existing infrastructure, would likely be the most appropriate locations for large-scale solar PV projects. These areas combine favorable topography with good solar exposure and minimal conflicts with other land uses.
