Solar PV Analysis of Fuzhou, China
Located at latitude 26.0492 and longitude 119.2906, Fuzhou, Fujian, China is a viable setting for solar photovoltaic (PV) power generation, given its considerable daily kilowatt-hour (kWh) per kilowatt (kW) of installed solar across all seasons. During the summer months, the city's average energy yield reaches an impressive 5.42 kWh per kW due to longer daylight hours and more direct sunlight exposure. The autumn season sees a slightly lower output of 3.98 kWh per kW as daylight hours begin to shorten.
In winter, despite shorter days and less intense sunlight, the city still manages an average production of 3.34 kWh per kW - demonstrating that even in less favorable conditions, solar PV systems can maintain a significant level of efficiency in Fuzhou's climate.
As spring arrives with lengthening days and strengthening sunlight intensity, there is a noticeable increase in energy production to an average of 4.07 kWh per kW.
The optimal angle for fixed panel installation in this location is a tilt towards the South at an angle of 23 degrees - this orientation maximizes exposure to incoming sunlight over the course of a year.
However, it should be noted that certain local weather conditions could potentially impede solar production at this location; heavy rainfall or dense fog can limit visibility and obstruct sunlight from reaching PV cells on panels – subsequently reducing their efficiency and overall power generation capacity.
To mitigate these potential challenges when installing solar panels in Fuzhou's climate conditions: consider incorporating water-resistant features or protective coatings on panels to safeguard against heavy rain; use advanced materials or technologies designed to maintain panel efficiency even under low-light or foggy conditions; ensure regular maintenance checks are conducted post-installation for early detection and rectification of any issues affecting performance such as dirt accumulation on panel surfaces from local environmental factors.
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 Fuzhou
Seasonal solar PV output for Latitude: 26.0492, Longitude: 119.2906 (Fuzhou, 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 23° South in Fuzhou, China
To maximize your solar PV system's energy output in Fuzhou, China (Lat/Long 26.0492, 119.2906) throughout the year, you should tilt your panels at an angle of 23° 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 Fuzhou, 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 Fuzhou, China. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 23° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 10° South in Summer | 30° South in Autumn | 41° South in Winter | 19° 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 Fuzhou, 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 Fuzhou, 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 Fuzhou, China
The topography around Fuzhou, China is generally flat with some hills and mountains in the surrounding area. Areas that would be most suitable for large-scale solar PV installations would be those with open, unobstructed access to direct sunlight such as rooftops or open fields. Areas near the coast may also have good potential for solar energy due to higher levels of sunshine and fewer obstructions from trees and buildings.
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.
