Solar PV Analysis of New Taipei City, Taiwan
New Taipei City in Taiwan is a pretty good place to generate electricity using solar panels all year round. This location gets more sunlight and has longer daylight hours during the summer, producing about 5.70 kilowatt-hours (kWh) of electricity per day for each kilowatt (kW) of installed solar power. That's the highest output among all seasons.
In autumn, the daily production drops slightly to 4.22 kWh/day per kW due to shorter days and less intense sunlight. Winter sees further reduction with an average of 3.51 kWh/day per kW because of even shorter daylight hours and lower sun intensity, but it picks up again in spring with an average production rate of 4.86 kWh/day per kW as days get longer.
To get the best out of your solar panel installation in New Taipei City, you should tilt your panels at a southward angle of 22 degrees - this allows them to capture as much sunlight as possible throughout the year.
However, there may be some challenges that could affect solar energy production at this location such as typhoons or heavy rainfall which are common weather events in Taiwan especially during late summer and early autumn; these can reduce sunshine duration thus affecting energy generation from solar panels. There might also be issues related to air pollution or dust accumulation on panel surfaces which could block sunlight penetration leading to reduced efficiency.
Preventive measures that can be taken include installing robust mounting systems that can withstand high wind speeds associated with typhoons, regular cleaning and maintenance checks on the panels surface for dust or debris removal ensuring maximum light absorption capacity is maintained; moreover installing advanced systems designed specifically for areas prone to high levels of air pollution might also help improve efficiency by reducing soiling losses caused by pollutants deposition on panel surfaces.
Overall though, given its geographical position within Northern Sub Tropics zone where there's plenty sunshine most parts of the year makes New Taipei City a reasonably good location for solar energy production.
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 New Taipei City
Seasonal solar PV output for Latitude: 24.9466, Longitude: 121.586 (New Taipei City, 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 22° South in New Taipei City, Taiwan
To maximize your solar PV system's energy output in New Taipei City, Taiwan (Lat/Long 24.9466, 121.586) 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.
Seasonally adjusted solar panel tilt angles for New Taipei City, 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 New Taipei City, Taiwan. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 22° 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 | 29° South in Autumn | 40° South in Winter | 18° 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 New Taipei City, 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 New Taipei City, 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 New Taipei City, Taiwan
New Taipei City, Taiwan is located on the northern part of the island. The topography is quite diverse with mountains in the southeast, flat plains in the northwest, and hills in between. The Tamsui River runs through parts of New Taipei City as well.
The area around New Taipei City has a mix of urban areas, agricultural lands and mountainous regions. As for solar PV installation, it would depend on various factors such as sunlight exposure (solar irradiance), land availability and use, proximity to power grids etc.
Considering these factors:
1) Flat Plains: The western part of New Taipei city which consists mostly of flat plains would be an ideal location for large-scale solar PV installations due to ample sun exposure and relatively easy installation process compared to hilly or mountainous regions.
2) Rooftop Solar Panels: In densely populated urban areas like Banqiao District or Xinzhuang District where open land might not be available for large scale installations, rooftop solar panels could be a feasible option.
3) Coastal Areas: Some coastal areas may also be suitable if they are not heavily developed or protected environmental zones.
4) Unused Agricultural Land: If there are any unused agricultural lands that receive good sun exposure year-round (especially those facing south), they can also serve as suitable locations for large-scale solar PV installations.
However, it's important to note that each potential site should undergo detailed feasibility studies including environmental impact assessments before proceeding with any kind of development.
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.
