In response to the GHG emission restriction rule of the Kyoto Accord, countries worldwide are further investing in renewable energy and substitute energy development. Currently, 98% of energy consumption in Taiwan relies on imports. For the benefit of national economic development and social-environmental protection, the Bureau of Energy launched a set of policies and goals for the development of solar energy in 2006 to establish the industry environment and popularize the application of solar power.

Though solar energy policies have evolved since then, the mission and goals of the 2006 mandate sprouted many inspiring projects and public constructions that are still admired today.

Goals and Strategy of the 2006 Solar Energy Development Guidelines[1]:

  • To actively promote demonstrative projects and strengthen the promotion of project establishment.
  • To enforce the establishment of emergency solar power systems in distant regions and off shore islands.
  • Accelerate development in the industry by investing in technological advancement and cost reduction, actively assist corporations in domestic market cultivation and foreign trade expansion, and to promote BIPV technology. The goal for building-installed PV systems was set to reach 100,000 to 120,000 homes by 2025.

Planned Policy Measures:

  • Solar City: The Solar City project plans to build solar powered buildings, municipal infrastructure or landmarks in several different locations in the city in order to boost the image of solar application. Details of installation projects would be proposed by the local city or county government, project subsidies would be evaluated by the Bureau of Energy.
  • Solar TOP: This measure differs from Solar City in that the project aims at constructing large, demonstrative solar power integrated establishments at key locations with high visibility. The constructions are to be designed with artistic diversity, cultural sensitivity and high technology. By combining public construction with solar power, the administration wishes to convey its seriousness of purpose in promoting renewable energy in Taiwan. Establishments are divided in two categories: 1. Structures with at least 60kWp and structural groups of at least 100kWp, 2. Transport facilities of at least 60kWp.
  • Emergency Disaster Prevention for Distant Regions: This measure planned to promote independent solar power systems in distant regions with limited access to grid power. It was estimated that at least one solar power system was installed in 50 mountainous counties and off shore islands.
  • Solar Roof: For the Solar Roof plan, solar modules are encouraged to be installed on existing buildings. The administration would subsidize USD$5000 for every kWp installed and under 50% of installation cost, in order to promote solar rooftop projects.

The solar power installation outside the Museum of Taiwan History was the result of the Solar TOP project initiated in 2006. Standing outside the museum is a beautiful solar panel wall stretching 148.2 meters in length and 15.57 meters in height. This magnificent building integrated PV (BIPV) structure was sponsored by the Bureau of Energy and erected by Hengs Solar Corp. as a testament of the R.O.C.’s achievements in technology and culture. Hengs is a professional company specializing in monitoring system integration established in 1998. The company founded its natural energy department in 2002 and has since focused on renewable energy system integration for public construction projects at home and abroad. Since its completion in 2009, the cloud wall has been a model structure in green architecture and a local landmark. Its construction was meant to play double roles, firstly as an integrator of modern science and traditional culture, and secondly as a successful solar power generator.

According to the museum image designer, the integration of the solar wall was a happy coincidence. The original design called for the incorporation of the concept of Taiwanese history into an ornate outer wall for the museum. The theme was to include images of ocean crossing and blue skies on the intended structure. BIPV was the best material for such a design.

The semi-transparent quality of BIPV reflects perfectly the clouds in the sky, imitating the blue waters through which our ancestors dared hundreds of years ago. The wall consists of 1700 pieces of PV modules, including 400 pieces of ceramic silkscreen glass that spells the words NATIONAL MUSEUM OF TAIWAN HISTORY. Behind the wall, a corridor leads visitors to a museum showroom, turning the structure and its scenic surroundings into a tourist attraction.

In its role as a solar power generator, the BIPV wall has an installed capacity of 195kWp. It generates 280,000kWh of energy annually, equal to conserving 145 tons of carbon dioxide. The power generated also helps the museum save more than US$23,000 on electricity bills every year.  The effort of National R.O.C. History Museum using solar technology is an example in model green construction. It was an innovative project for the museum, the solar panel provider and the construction team. Thanks to their efforts, the people now have a beautiful green landmark.
