Solar PV Analysis of Jiaxing, China
The location at Jiaxing, Zhejiang, China, is quite suitable for generating energy using solar panels throughout the year. The amount of electricity that can be produced from each kilowatt (kW) of installed solar power varies with the seasons: it's highest in summer (4.90 kilowatt-hours per day), followed by spring (4.29 kWh/day), autumn (3.87 kWh/day), and lowest in winter (3.12 kWh/day).
This means that more electricity is generated during warmer months when there are longer daylight hours and stronger sunlight intensity - making summer and spring ideal times for solar energy production here.
For fixed panel installations at this location, tilting the panels 28 degrees towards the south will help maximise total yearly production from your solar power system because it aligns them better with the sun's path across the sky.
However, there might be local factors that could affect how much energy you can produce from your solar installation in Jiaxing. For example, if this area experiences heavy rainfall or pollution often, these could block sunlight from reaching your panels and reduce their efficiency.
To overcome these potential challenges:
1) Regularly cleaning your panels will ensure they're free of dust or other particles that could obstruct light.
2) If possible, installing a tracking system that moves your panels to follow the sun throughout the day may also increase their exposure to sunlight.
3) Using high-quality equipment designed to withstand different weather conditions can also help maintain good performance even during less-than-ideal conditions.
In summary, while there are some considerations to keep in mind when installing a solar PV system in Jiaxing due to varying seasonal outputs and potential environmental factors like rainfall or pollution; overall it is a pretty good location for harnessing solar energy year-round if managed properly.
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 319 locations across China. 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 Jiaxing
Seasonal solar PV output for Latitude: 30.7488, Longitude: 120.7486 (Jiaxing, 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 28° South in Jiaxing, China
To maximize your solar PV system's energy output in Jiaxing, China (Lat/Long 30.7488, 120.7486) throughout the year, you should tilt your panels at an angle of 28° 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 Jiaxing, 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 Jiaxing, China. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 28° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 15° South in Summer | 36° South in Autumn | 46° South in Winter | 23° 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 Jiaxing, 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 Jiaxing, 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 Jiaxing, China
Jiaxing, situated in the northeastern Zhejiang province of China, is characterized by flat plains with a few rolling hills. The city is located in the Yangtze River Delta and has numerous water bodies including rivers, lakes and canals. It has an extensive network of waterways which contribute to its relatively humid climate.
The topography is quite favorable for large-scale solar photovoltaic (PV) installations due to its flat lands which provide ample space for such projects. In addition, Jiaxing receives a good amount of sunlight throughout the year making it suitable for solar power generation.
Nearby areas that would be most suited for large-scale solar PV installations include:
1. Flat agricultural lands: These areas are usually ideal as they provide plenty of open space and are often free from obstructions like tall buildings or trees that could shade the panels.
2. Industrial zones: Large rooftops on factories or warehouses offer great potential for installing rooftop solar PV systems.
3. Unused land near transportation infrastructure like highways or railways: Such locations often have good access and may be less likely to face opposition from local communities than projects in more visible locations.
4. Areas around lakes or reservoirs: Floating solar farms could be an option here as they save valuable land resources while also reducing evaporation from reservoir surfaces.
However, any decision about where to place a large-scale PV installation should take account not only of physical factors but also socio-economic ones such as local regulations, potential impact on biodiversity or agriculture, proximity to electricity grids and roads etc., so detailed local studies would be necessary before proceeding with any project.
China solar PV Stats as a country
China ranks 1st in the world for cumulative solar PV capacity, with 306,973 total MW's of solar PV installed. This means that 6.20% of China's total energy as a country comes from solar PV (that's 13th in the world). Each year China is generating 217 Watts from solar PV per capita (China ranks 24th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in China?
Yes, there are several incentives for businesses wanting to install solar energy in China. These include subsidies from the Chinese government, preferential tax policies, and access to low-interest loans. Additionally, businesses may be eligible for renewable energy certificates (RECs) which can be sold on the open market for additional income.
