Solar Energy Potential in Yulinshi, Shaanxi, China

Yulinshi, Shaanxi, China, located in the Northern Temperate Zone at coordinates 38.288, 109.7373, offers varying potential for solar energy generation throughout the year. This location experiences significant seasonal fluctuations in solar electricity production that are worth understanding for anyone considering solar panel installation. The solar energy output at this location shows a clear seasonal pattern. Summer stands out as the most productive season, generating approximately 7.00 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second most productive season with 6.15 kWh/day. Energy production drops considerably during autumn (3.98 kWh/day) and reaches its lowest point in winter (3.43 kWh/day).

Seasonal Variations and Ideal Generation Periods

The substantial difference between summer/spring and autumn/winter production indicates that Yulinshi has a somewhat uneven solar generation profile throughout the year. The location is most ideal for solar energy production from late spring through early autumn, with peak performance occurring during the summer months. During these peak periods, solar installations can operate at nearly twice the efficiency compared to winter months. For fixed solar panel installations at this location, the ideal angle to maximize year-round production is 34 degrees tilted toward the South. This specific angle has been calculated to optimize annual solar energy capture based on Yulinshi's geographical position in the Northern Hemisphere.

Environmental Challenges and Mitigation Strategies

A significant environmental factor that could impede solar production in Yulinshi is dust accumulation. The city is located near the edge of the Mu Us Desert and the Loess Plateau, areas known for dust storms and high particulate matter in the air. These conditions can reduce solar panel efficiency by creating a layer of dust that blocks sunlight from reaching the photovoltaic cells. To mitigate this challenge, several preventative measures can be implemented:

• Regular cleaning schedules should be established, with increased frequency during spring when dust storms are more common
• Installation of panels at steeper angles than the optimal 34 degrees may be considered in particularly dusty areas to promote natural cleaning through rainfall
• Anti-soiling coatings can be applied to panel surfaces to reduce dust adhesion
• Automated cleaning systems might be economically justified for larger installations

Additionally, the region experiences cold winters with occasional snow, which can temporarily cover panels. Installing panels at the recommended 34-degree tilt helps shed snow more effectively than flatter installations would, though manual clearing may still be necessary after heavy snowfall events. With proper installation techniques and maintenance protocols addressing these environmental factors, solar energy remains a viable and increasingly attractive option for electricity generation in Yulinshi.

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

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

Seasonal solar PV output for Latitude: 38.288, Longitude: 109.7373 (Yulinshi, China), 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 34° South in Yulinshi, China

To maximize your solar PV system's energy output in Yulinshi, China (Lat/Long 38.288, 109.7373) throughout the year, you should tilt your panels at an angle of 34° 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 Yulinshi, China

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 Yulinshi, China. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 34° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
22° South in Summer	43° South in Autumn	53° South in Winter	30° 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 Yulinshi, China

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 Yulinshi, China.

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 Yulinshi, China

Yulinshi, located in northern Shaanxi Province, China, sits at the southern edge of the Ordos Desert and the northern reaches of the Loess Plateau. This transitional zone creates a distinctive topographical landscape characterized by a mix of desert features and loess formations. The terrain around Yulinshi consists predominantly of undulating hills and plateaus, with numerous ravines and gullies carved by water erosion over millennia. The elevation generally ranges between 1,000 to 1,300 meters above sea level, creating a moderately elevated landscape. The Yulin area features significant loess deposits—fine, yellowish silt sediments that have accumulated over geological time and formed the characteristic plateau landforms.

Desert and Loess Features

To the north of Yulinshi, the landscape transitions into the more arid Mu Us Desert (part of the larger Ordos Desert region), characterized by sand dunes, sparse vegetation, and flat expanses. This desert region presents relatively flat topography with sandy soils. Meanwhile, the southern portions feature the deeply eroded loess formations with steeper slopes and more complex terrain patterns. The area is crossed by several seasonal rivers and streams, including tributaries of the Yellow River system. These waterways have carved deep channels through the soft loess soil, creating a network of valleys and gullies that fragment the landscape, particularly in the plateau regions to the south.

Optimal Areas for Solar PV Development

For large-scale solar photovoltaic installations, the northern desert regions surrounding Yulinshi offer particularly favorable conditions. These areas provide several advantageous characteristics: The desert plains north of Yulinshi present extensive flat or gently sloping terrain that minimizes the need for land grading and reduces construction costs. These open expanses allow for efficient arrangement of solar panels and supporting infrastructure. The sandy desert regions typically have minimal competing land uses compared to agricultural areas in the loess regions to the south. This reduced land-use competition makes permitting and development potentially less complicated. The sparse vegetation in the desert areas reduces concerns about shading and minimizes the environmental impact of clearing land for solar installations. The natural openness of the landscape already provides the unobstructed exposure needed for optimal solar collection. The relatively stable sand and soil conditions in the desert flats north of Yulinshi offer good foundation potential for solar array mounting systems, though proper engineering for wind resistance would be essential given the region's exposure to seasonal winds. By contrast, the deeply dissected loess regions to the south present more challenges for large-scale solar development due to their irregular topography, greater potential for soil erosion, and more complex land management considerations. The transition zones between the desert and loess regions may offer a compromise, providing reasonably flat terrain while being somewhat less exposed to the most extreme desert conditions, potentially reducing maintenance challenges related to sand accumulation and abrasion on solar equipment.
