Solar PV Analysis of Jiamusi, China
Jiamusi, Heilongjiang, China, situated at latitude 46.7961 and longitude 130.3112, presents a mixed scenario for solar PV energy generation throughout the year. Located in the Northern Temperate Zone, this city experiences significant seasonal variations in solar output.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive 5.89 kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind, generating 5.45 kWh/day. However, the output drops considerably during autumn (3.23 kWh/day) and reaches its lowest point in winter (2.63 kWh/day).
These figures indicate that Jiamusi is particularly well-suited for solar energy production during the warmer months. The extended daylight hours and higher sun angles in summer and spring contribute to this increased efficiency. Conversely, the shorter days and lower sun angles in autumn and winter result in reduced solar output.
Optimal Panel Installation
To maximize year-round solar production in Jiamusi, Heilongjiang, fixed solar panels should be tilted at an angle of 42 degrees facing south. This optimal angle takes into account the city's latitude and the sun's position throughout the year, ensuring the best possible exposure to sunlight across all seasons.
Environmental Factors and Mitigation
Jiamusi's location presents some challenges for solar energy production. The city experiences long, cold winters with frequent snowfall, which can potentially cover solar panels and reduce their efficiency. To mitigate this issue, solar installations should include snow-shedding features and regular maintenance plans for snow removal.
Additionally, Jiamusi is known for its occasional haze and air pollution, particularly during winter months. This can slightly reduce solar panel efficiency. Installing high-quality, anti-soiling glass on panels and implementing regular cleaning routines can help maintain optimal performance.
Despite these challenges, with proper planning and maintenance, Jiamusi can still be a viable location for solar PV energy generation, particularly capitalizing on the high productivity during summer and spring months.
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 Jiamusi
Seasonal solar PV output for Latitude: 46.7961, Longitude: 130.3112 (Jiamusi, 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 42° South in Jiamusi, China
To maximize your solar PV system's energy output in Jiamusi, China (Lat/Long 46.7961, 130.3112) 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 Jiamusi, 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 Jiamusi, China. 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 | 39° 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 Jiamusi, 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 Jiamusi, China.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Jiamusi, China
The topography around Jiamusi, China, is characterized by a mix of flat plains and gently rolling hills. The city itself is situated in the Songhua River valley, which is part of the larger Sanjiang Plain. This plain is one of the most extensive flat areas in northeastern China, formed by the confluence of three major rivers: the Songhua, Heilong (Amur), and Wusuli.
To the north and east of Jiamusi, the terrain remains relatively flat, with vast agricultural fields dominating the landscape. As you move further east, you'll encounter the Lesser Khingan Mountains, which form a natural boundary between China and Russia. These mountains are not particularly high, with most peaks reaching between 500 to 1,000 meters above sea level.
To the south and west of Jiamusi, the land gradually becomes more undulating, with low hills and small valleys interspersed with areas of flat terrain. This region is part of the transition zone between the Sanjiang Plain and the Greater Khingan Mountains further to the west.
Regarding areas suitable for large-scale solar PV installations, the flat plains surrounding Jiamusi offer the most promise. These areas have several advantages for solar energy production:
- Ample open space with minimal obstruction from natural features or buildings
- Easy access for construction and maintenance
- Relatively uniform solar exposure throughout the day
- Proximity to existing infrastructure and population centers
The agricultural lands to the north and east of Jiamusi would be particularly well-suited for solar PV installations. These areas already have road networks in place and are generally free from major geographical obstacles. However, it's important to consider the balance between energy production and preserving valuable farmland.
The gently rolling hills to the south and west of Jiamusi could also accommodate solar farms, though they may require more careful site selection and planning to maximize sun exposure and minimize installation challenges. These areas might be preferable if there's a desire to preserve more of the flat, prime agricultural land for farming purposes.
It's worth noting that while Jiamusi's latitude means it receives less intense sunlight compared to more southern regions, the long summer days in this northern area can partially compensate for this, making large-scale solar PV projects viable with proper planning and technology selection.
