Gaomi, Shandong, China, situated at latitude 36.3861 and longitude 119.7529, offers a promising location for solar energy generation throughout the year. Located in the Northern Temperate Zone, this area experiences distinct seasonal variations in solar output, providing both opportunities and challenges for photovoltaic (PV) systems.
Seasonal Solar Performance
The solar energy potential in Gaomi varies significantly across seasons. Summer and spring are the most productive periods, with an impressive 5.42 kWh per day for each kilowatt of installed solar capacity. Autumn sees a moderate decrease to 3.56 kWh/day, while winter experiences the lowest output at 3.13 kWh/day per kW installed.
This seasonal pattern indicates that Gaomi is particularly well-suited for solar energy generation during the warmer months. The extended daylight hours and typically clearer skies in summer and spring contribute to the higher energy yields during these seasons.
Optimal Panel Positioning
To maximize year-round solar production in Gaomi, Shandong, fixed solar panels should be tilted at a 33-degree angle facing south. This optimal tilt angle ensures that the panels capture the most sunlight possible throughout the year, balancing the sun's changing position across seasons.
Environmental Considerations
While Gaomi's location is generally favorable for solar energy production, there are some environmental factors to consider:
- Air pollution: Being in an industrialized region of China, Gaomi may experience periods of increased air pollution, which can reduce solar panel efficiency.
- Dust and particulate matter: The area's climate can lead to dust accumulation on panels, potentially decreasing their effectiveness.
To mitigate these issues, regular cleaning and maintenance of solar panels is crucial. Installing panels at a slight angle helps with natural cleaning during rainfall. Additionally, using high-quality, anti-reflective coatings on panels can improve performance in less-than-ideal conditions.
In conclusion, Gaomi's location offers substantial potential for solar energy generation, particularly during summer and spring. With proper installation techniques and regular maintenance, solar PV systems in this area can provide significant energy output throughout the year.

Solar output per kW of installed solar PV by season in Gaomi
Seasonal solar PV output for Latitude: 36.3861, Longitude: 119.7529 (Gaomi, 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 Gaomi, China
To maximize your solar PV system's energy output in Gaomi, China (Lat/Long 36.3861, 119.7529) 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 Gaomi, 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 Gaomi, 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 |
|---|---|---|---|
| 20° South in Summer | 41° South in Autumn | 51° South in Winter | 29° 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 Gaomi, 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 Gaomi, 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 Gaomi, China
The topography around Gaomi, China, located at latitude 36.3861 and longitude 119.7529, is characterized by relatively flat terrain with gentle undulations. This area is part of the North China Plain, a vast expanse of lowlands that stretches across eastern China. The landscape surrounding Gaomi primarily consists of agricultural fields, interspersed with small villages and scattered patches of vegetation. The region experiences a temperate climate with distinct seasons, which has shaped the local terrain over time. The flat nature of the land is a result of centuries of sediment deposition from rivers and streams that flow through the area. This has created a fertile plain ideal for agriculture, which is the dominant land use in the region. While there are no significant mountains or hills in the immediate vicinity of Gaomi, the terrain does have subtle variations in elevation. These slight changes in topography are often imperceptible to the naked eye but can be detected through detailed surveys. Small rivers and irrigation channels crisscross the landscape, providing water for the extensive farmlands that dominate the area.
Suitability for Large-Scale Solar PV
When considering areas near Gaomi for large-scale solar photovoltaic (PV) installations, several factors come into play. The flat terrain of the North China Plain offers numerous advantages for solar energy development. Large, open spaces with minimal shading from natural features are abundant, making it easier to install and maintain extensive arrays of solar panels. The areas most suited for large-scale solar PV would be the expansive agricultural fields that surround Gaomi. These locations offer several benefits: Firstly, they provide ample space for deploying a significant number of solar panels without the need for major land alterations. The flat nature of the terrain reduces construction costs and simplifies the installation process. Secondly, these areas typically have good exposure to sunlight throughout the day, which is crucial for maximizing solar energy production. The lack of tall natural features or urban structures means there are fewer obstacles to block sunlight. Thirdly, the existing road network that serves the agricultural areas can be utilized for transportation and maintenance of solar equipment, reducing the need for additional infrastructure development. However, it's important to note that the use of agricultural land for solar installations may require careful planning and consideration of local food production needs. Ideally, areas of lower agricultural productivity or degraded lands would be prioritized for solar development to minimize the impact on food security. Additionally, areas near existing electrical infrastructure, such as power lines and substations, would be particularly advantageous for large-scale solar PV projects. This proximity would reduce the costs associated with connecting the solar installations to the grid and transmitting the generated electricity to consumers. In conclusion, while the entire region around Gaomi offers potential for solar PV development due to its favorable topography, the most suitable areas would be those that balance the need for open, flat land with minimal impact on productive agriculture and proximity to existing energy infrastructure.China solar PV Stats as a country
