Solar PV Analysis of Chang-hua, Taiwan
The location at Chang-hua, Changhua, Taiwan is quite good for year-round solar energy production. The amount of electricity that can be generated from a solar panel depends on the amount of sunlight it receives, which varies throughout the year. In summer, when days are longest and sunniest, you could expect to generate around 6.15 kilowatt-hours (kWh) per day for each kilowatt (kW) of solar panels installed. This decreases slightly in autumn to about 4.84 kWh/day and further drops in winter to approximately 3.74 kWh/day due to shorter daylight hours and less intense sunlight. However, it starts increasing again in spring with an average output of 5.14 kWh/day.
In terms of the best times of year for generating solar power at this location, summer would be ideal due to longer daylight hours followed by spring and then autumn; whereas winter might not be as productive due to fewer daylight hours.
For a fixed panel installation at this location, positioning your panels tilted at an angle facing 21 degrees South will help maximize total annual energy production as it aligns well with the path of the sun across the sky throughout different seasons.
As for potential factors that could affect solar production; Chang-hua is located in Northern Sub Tropics where weather conditions such as heavy rainfalls or typhoons might occasionally impede sunlight reaching your panels thereby affecting their performance significantly during those periods. Also dust accumulation on panels can reduce their efficiency over time if not cleaned regularly.
Preventative measures include installing sturdy mounting systems capable of withstanding high wind speeds common during typhoons and ensuring regular maintenance like cleaning off dust or debris from your panels so they continue performing optimally even under less than ideal conditions.
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 36 locations across Taiwan. 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 Chang-hua
Seasonal solar PV output for Latitude: 24.0759, Longitude: 120.5657 (Chang-hua, Taiwan), 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 21° South in Chang-hua, Taiwan
To maximize your solar PV system's energy output in Chang-hua, Taiwan (Lat/Long 24.0759, 120.5657) throughout the year, you should tilt your panels at an angle of 21° 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 Chang-hua, Taiwan
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 Chang-hua, Taiwan. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 21° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 8° South in Summer | 28° South in Autumn | 39° South in Winter | 17° 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 Chang-hua, Taiwan
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 Chang-hua, Taiwan.
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 Chang-hua, Taiwan
Chang-hua, Taiwan is located in the Changhua County on the west coast of Taiwan. The topography of this region is predominantly flat and it is situated in a coastal plain with some hilly areas towards the east. It has fertile lands due to its location at the delta of Zhuoshui River, which is the longest river in Taiwan.
The flatness and ample sunlight make it quite suitable for large-scale solar PV installations. In fact, Changhua Coastal Industrial Park has been identified as an ideal spot for such projects.
In addition, offshore areas around Chang-hua are also considered good for large-scale solar power generation due to high irradiation levels and consistent wind patterns that reduce cloud cover. The Taiwanese government has initiated several offshore floating solar projects along this coastline.
However, environmental impact assessments would need to be conducted before any large-scale project can be implemented to ensure minimal disruption to local ecosystems and communities.
Taiwan solar PV Stats as a country
Taiwan ranks 17th in the world for cumulative solar PV capacity, with 7,700 total MW's of solar PV installed. Each year Taiwan is generating 327 Watts from solar PV per capita (Taiwan ranks 12th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Taiwan?
Yes, there are incentives for businesses wanting to install solar energy in Taiwan. The Taiwanese government offers a number of financial incentives and subsidies for businesses that install solar energy systems. These include tax credits, grants, low-interest loans, and feed-in tariffs. Additionally, the government has implemented a Renewable Energy Certificate (REC) system which allows businesses to trade renewable energy certificates with other companies or organizations in order to receive additional financial benefits.
