Solar Panel Tilt Angle in Taiwan
So far based on Solar PV Analysis of 34 locations in Taiwan, we've discovered that the ideal angle to tilt solar PV panels in Taiwan varies between 22° from the horizontal plane facing South in Taoyuan and 20° from the horizontal plane facing South in Hualien City.
These tilt angles are optimised for maximum annual PV output at each location for fixed-panel solar PV installations. If you click on one of the locations above, there is further detail on ideal seasonal tilt angles as well (in case your solar panels are adjustable).
Depending on where you are based in Taiwan, the ideal angle to tilt your solar panels will vary by approx 2 degrees (between 22° from the horizontal plane facing South and 20° from the horizontal plane facing South).
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.
