Yantai, Shandong, China, located at 37.4765° N, 121.4408° E in the Northern Temperate Zone, offers moderately favorable conditions for solar PV energy generation throughout the year. The seasonal electricity output shows significant variation across the year, with stronger production during the warmer months.

Seasonal Solar Performance

Solar panels in Yantai perform best during summer, generating approximately 5.43 kWh per day for each kilowatt of installed capacity. Spring follows closely with 5.30 kWh/day, making these two seasons the prime time for solar energy production. Autumn sees a notable decrease to 3.44 kWh/day, while winter drops further to 2.74 kWh/day per kilowatt installed.

This seasonal pattern means that Yantai experiences almost twice the solar production in summer compared to winter months, which is typical for locations in the Northern Temperate Zone. The strong spring performance is particularly valuable, providing nearly summer-level output earlier in the year.

Optimal Panel Installation

For fixed solar panel installations in Yantai, Shandong, the ideal tilt angle to maximize year-round production is 33 degrees facing South. This angle has been calculated based on the location's latitude and seasonal solar elevation patterns, weighted by the potential daily PV output throughout the year.

Environmental Considerations

Several environmental factors in Yantai could impact solar production:

• Coastal air pollution and industrial haze from nearby manufacturing centers can reduce solar irradiance reaching panels
• Seasonal dust storms from northern China in spring may coat panels with particulate matter
• Winter snow accumulation can temporarily block panels
• Typhoon activity during late summer and early autumn poses risk to installations

To mitigate these challenges, solar installations in Yantai should incorporate regular cleaning systems to address dust and pollution buildup. Snow-shedding panel designs with steeper winter tilt options would improve winter performance. Additionally, robust mounting systems rated for typhoon-force winds are essential for system longevity, while slightly elevating installations can reduce snow accumulation issues.

Overall, Yantai offers good solar potential with proper system design accommodations for local conditions, particularly taking advantage of the excellent spring and summer production periods.

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

Seasonal solar PV output for Latitude: 37.4765, Longitude: 121.4408 (Yantai, 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 33° South in Yantai, China

To maximize your solar PV system's energy output in Yantai, China (Lat/Long 37.4765, 121.4408) throughout the year, you should tilt your panels at an angle of 33° 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 Yantai, 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 Yantai, China. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
21° South in Summer	42° South in Autumn	52° 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 Yantai, 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 Yantai, 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 Yantai, China

The topography around Yantai, a coastal city in eastern Shandong Province, China, is characterized by a diverse landscape that transitions from coastal plains to rolling hills and low mountains as one moves inland. Situated on the southern coast of the Bohai Strait, Yantai features a varied terrain that has been shaped by both geological processes and human activity over centuries. Along the immediate coastline, Yantai presents relatively flat lowlands with sandy beaches and small bays. This coastal plain extends several kilometers inland before the terrain begins to undulate. The Shandong Peninsula, on which Yantai is located, is generally hilly with elevations gradually increasing as one moves away from the shore.

Inland Terrain Features

Moving inland from Yantai's urban center, the landscape transforms into gently rolling hills that become more pronounced further south. These hills typically range from 100 to 300 meters in elevation, creating a pleasant, varied topography. The Kunyu Mountain range, located in the southern part of Yantai's administrative area, represents the highest terrain in the region with peaks reaching approximately 900 meters above sea level. The area features numerous small valleys and watersheds formed by seasonal streams and rivers that flow toward the Bohai Sea. These waterways have carved natural corridors through the hilly terrain, creating microclimates and varying slope aspects throughout the region.

Agricultural and Modified Landscapes

Much of the gentler terrain around Yantai has been modified for agricultural use, with terracing common on hillsides. Fruit orchards, particularly apple and cherry, occupy many of the hillsides where the elevation and slope provide ideal growing conditions. The flatter areas are typically used for row crops and vegetable cultivation.

Optimal Areas for Solar PV Development

For large-scale solar photovoltaic (PV) installations, several areas around Yantai present favorable conditions based on topographical considerations: The inland plains and gently sloping areas south of the main urban center offer substantial flat or slightly inclined terrain that would minimize grading costs for solar installations. These areas, particularly in the counties of Laiyang and Qixia, combine adequate land availability with favorable south-facing aspects. The moderately elevated plateaus between hills, especially those with southern exposures, provide excellent potential sites. These areas typically receive minimal shadowing from surrounding terrain and offer good solar access throughout the year. The slightly elevated nature of these sites also tends to reduce fog exposure compared to the immediate coastal areas. Some of the reclaimed or less productive agricultural land in the region could be repurposed for solar development. Areas where soil quality or water availability limits agricultural productivity but which have good solar exposure represent prime candidates for conversion to solar energy production. The coastal plain areas, while flat and seemingly ideal, must be carefully evaluated due to potential salt spray exposure and higher corrosion factors. However, some coastal zones with adequate setback from the immediate shoreline could be suitable, particularly where they offer easy access to transmission infrastructure. Areas to avoid would include the steeper slopes of the Kunyu Mountains, densely forested zones, and locations with northern aspects that receive significantly reduced direct solar radiation. Additionally, areas prone to seasonal flooding or with cultural or ecological significance would present challenges for development. The combination of varied terrain, relatively moderate elevation changes, and substantial areas of open land makes the broader Yantai region generally favorable for solar PV development, with site-specific evaluations necessary to identify the most optimal locations.
