1.Research and analysis of the current situation of applying solar panels to acoustic barriers for the transportation system in foreign countries
This Project has completed collection of information in 15 countries in Europe, America, and Asia-Pacific, and sorted out the promotional practice characteristics and research methods in these countries in terms of application of solar acoustic barriers to reduce air pollution, traffic noises, and carbon emission, which may be used as a reference for our country. This Project has conducted field demonstrative installation testing and proposed an innovative practice of “single-sided solar panels + single-sided sound absorbing panels”, making reference of the practice of “double-sided vertical solar panels (90° inclination)” adopted in foreign countries.
2.Field demonstration and testing on application of modified solar panels to acoustic barriers for the transportation system
With the cooperation of Taiwan Railways Administration, MOTC, this Project set up the first system of solar acoustic barriers for the transportation system in our country at Beihu Station (including the show kiosk and display board). Totally, 225 solar panels are used (including 6 on the roof of the show kiosk) for the purpose with a total area of around 405m2. The total installed capacity of these solar panel acoustic barriers is around 64.2 kW, which is used for internal grid connection at Beihu Station. During the 6-month period between July and December, 2019, the accumulative total power generation of the system was around 15,564.4 kWh, averagely 85 kWh per day, resulting in a remission reduction of around 2.8 kg SOx, 3.5 kg NOx, 0.3 kg PM, and 8.3 tonne CO2. The insertion loss of noise with the solar panel acoustic barriers in “field measurement” is around 10 dB(A).
3.Evaluation of the efficiency on environment improvements, such as reduction of air pollution, noises, and carbon emission, by applying solar panels to acoustic barriers for the transportation system
In this Project, the Project team has organized two advisory meetings and, through exchange of opinions among related experts and authorized representatives, proposed more advanced practices for the implementation of this Project. In the case that all conditions are fulfilled, the government may as well take the implementation results of this Project as reference in future policy making. We recommend that more scale-up trials or demonstrations be conducted at proper places in Central and Southern Taiwan. It is advisable to create policies that facilitate exploration of new materials through related R＆D plans (such as air pollution plans initiated by MOST and technology consulting programs by EVA) to make solar panel acoustic barriers capable of absorbing (instead of being adhered to) chemical substances, such as CO and HC, apart from generating power with solar panels, in order to achieve the goal of green transportation with such benefits as green energy, carbon reduction, environmental protection, and noise reduction.
