Sanxia District in Taiwan, located in the Northern Sub-Tropics, offers a generally favorable environment for solar PV energy generation throughout the year. The location's seasonal solar output varies, with summer being the most productive period and winter the least.

Seasonal Solar Performance

Summer stands out as the peak season for solar energy production, with an impressive 5.70 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second most productive season, generating 4.86 kWh/day. Autumn sees a slight decrease to 4.22 kWh/day, while winter experiences the lowest output at 3.51 kWh/day per kW installed.

The substantial difference between summer and winter production highlights the impact of seasonal variations on solar energy generation in Sanxia District. However, even during the least productive winter months, the output remains relatively good, indicating that solar PV systems can still contribute significantly to energy needs year-round.

Optimal Panel Installation

For fixed panel installations in Sanxia District, New Taipei City, the ideal tilt angle to maximize year-round solar production is 22 degrees facing South. This angle has been calculated to optimize energy capture across all seasons, taking into account the location's latitude and the Earth's elliptical orbit.

Environmental Considerations

While Sanxia District generally provides good conditions for solar energy production, there are some environmental factors to consider:

1. Typhoons: Taiwan is prone to typhoons, which can potentially damage solar installations. To mitigate this risk, robust mounting systems and high-quality, weather-resistant panels should be used.
2. High humidity: The subtropical climate means high humidity levels, which can lead to moisture-related issues. Proper sealing and ventilation of electrical components are crucial to prevent corrosion and ensure longevity.

By addressing these factors during installation and maintenance, solar PV systems in Sanxia District can achieve optimal performance and durability, making the most of the location's favorable solar conditions throughout the year.

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.

Ideally tilt fixed solar panels 22° South in Sanxia District, Taiwan

To maximize your solar PV system's energy output in Sanxia District, Taiwan (Lat/Long 24.9337, 121.372) throughout the year, you should tilt your panels at an angle of 22° 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.

At Latitude: 24.9337, Longitude: 121.372, the ideal angle to tilt panels is 22° South

Seasonally adjusted solar panel tilt angles for Sanxia District, 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 Sanxia District, Taiwan. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 22° South tilt angle throughout the year.

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 Sanxia District, 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 Sanxia District, Taiwan.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Sanxia District, Taiwan

The topography around Sanxia District in Taiwan is characterized by a diverse landscape that transitions from urban areas to hilly and mountainous terrain. Sanxia is situated in a river valley, with the Sanxia River flowing through the district. The area is part of the western foothills of Taiwan's Central Mountain Range, which means the landscape becomes increasingly rugged and elevated as you move eastward.

In the western part of Sanxia, closer to the more densely populated areas of New Taipei City, the terrain is relatively flat and urbanized. As you move towards the east and northeast, the landscape gradually becomes more hilly, with numerous small valleys and ridges. These hills are often covered in lush vegetation, including forests and tea plantations, which are common in this region.

The eastern portions of Sanxia District feature more dramatic elevation changes, with some peaks reaching heights of several hundred meters above sea level. This mountainous area is part of the Manyueyuan National Forest Recreation Area, known for its scenic beauty and biodiversity.

Regarding areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, the ideal locations would be in the flatter, western parts of Sanxia District and the neighboring areas. These regions offer several advantages for solar energy development:

1. They have more open, level ground, which is easier and more cost-effective for installing large arrays of solar panels.
2. The lower elevation means less cloud cover and fog compared to the mountainous areas, resulting in more consistent sunlight exposure.
3. These areas are closer to existing power infrastructure and population centers, making it easier to connect to the grid and distribute the generated electricity.

However, it's important to note that Taiwan faces challenges in finding suitable land for large-scale solar installations due to its high population density and limited flat terrain. As a result, many solar projects in the region focus on rooftop installations or smaller-scale ground-mounted systems. Some nearby areas that might be considered for solar PV development include parts of Taoyuan City to the west or some of the less mountainous areas in neighboring Yingge District.

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.
