Solar PV Analysis of Jinshan, Taiwan
Jinshan, New Taipei City, Taiwan is a reasonably good location for year-round solar energy production, but it's not perfect. The amount of electricity you can get from solar panels changes with the seasons. In summer, each kilowatt of installed solar can produce 6.20 kilowatt-hours per day. This drops to 4.26 in autumn and further to 2.87 in winter before rising back up to 4.50 in spring.
So while you'll get the most energy in the summer, even during winter - when sunlight is least abundant - you're still getting some power from your panels.
To make sure your panels are as efficient as possible all year round at this location, they should be tilted at an angle of 21 degrees facing south.
However, there might be some local factors that could affect how much power you get from your solar installation here:
1) Weather: Jinshan has a subtropical climate which means it experiences heavy rainfall especially during monsoon season (May-October). Rainy or cloudy days will decrease the amount of sunlight reaching your panels hence less electricity produced.
Preventative measure: Install a system that allows for automatic adjustment and tracking of sun position throughout the day to maximize exposure during sunny hours.
2) Dust and Pollution: Dust or other particles can settle on the surface of solar panels reducing their efficiency.
Preventative measure: Regular cleaning and maintenance schedule would help keep them running efficiently.
3) Shading: Any nearby buildings or trees could potentially cast shadows on your panel reducing its efficiency.
Preventative measure: Carefully choose where to place your panels so they aren't shaded for any part of the day by surrounding structures or vegetation.
In summary – yes, Jinshan is suitable for generating solar energy all year round with summer being particularly productive; however attention must be paid to weather patterns such as rainfalls along with regular maintenance against dust accumulation and shading issues.
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 Jinshan
Seasonal solar PV output for Latitude: 25.0613, Longitude: 121.5705 (Jinshan, 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 Jinshan, Taiwan
To maximize your solar PV system's energy output in Jinshan, Taiwan (Lat/Long 25.0613, 121.5705) 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 Jinshan, 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 Jinshan, 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 |
|---|---|---|---|
| 9° 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 Jinshan, 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 Jinshan, 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 Jinshan, Taiwan
Jinshan, Taiwan is located in the northern part of the country. The topography around this area is characterized by a mix of coastal plains and mountainous regions. The region has an uneven terrain with numerous hills and valleys. There are also several rivers flowing through the region.
As for solar PV installations, flat areas or slopes facing south (for Northern Hemisphere locations like Taiwan) are generally considered ideal to maximize sun exposure throughout the day. Considering Jinshan's topography, potential suitable areas could be:
1. Coastal Plains: These flat lands along the coast can be ideal for setting up large-scale solar farms due to their relatively even terrain.
2. Cleared Hilltops: While hilltops might not seem like an obvious choice due to gradient issues, they receive good sunlight exposure if trees and other obstructions are cleared.
3. Near Infrastructure: Areas near existing infrastructure such as roads or power lines would help reduce installation costs associated with connecting a new solar farm to the grid.
However, it should be noted that site selection for large-scale solar projects involves various factors beyond just topography - including land use restrictions, environmental considerations (like biodiversity impacts), proximity to electrical grids for transmission efficiency and local climate conditions (amount of annual sunshine hours). Therefore, detailed feasibility studies would need to be conducted on any proposed sites before proceeding with development plans.
Additionally, Taiwan is known for its high population density and limited available land which may pose challenges in identifying suitable locations for large scale solar PV farms without disturbing residential areas or valuable agricultural lands.
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.
