“…The comments provided by the reviewers assist the installer in revising the system design. However, Chang et al [15] announced regional subsidy programs for SWHs. An additional subsidy was offered to local households when an SWH is purchased, thus leading to a tremendous increase in sales.…”

Abstract:In response to the impact of the United Nations Framework Convention on Climate Change, developing and using renewable energy sources and technologies have become vital for managing energy supply and demand in Taiwan. The long-term subsidy programs (1986-1991, 2000-present) for solar water heaters (SWHs) launched by the Taiwanese government constitute the main driving force for market expansion. By the end of 2013, the cumulative area of installed solar collectors was 2.27 million m 2 . Approximately 0.3 million systems (or 1.545 million m 2 ) are in operation. This corresponds to an annual collector yield of 0.92 TWh, which is equivalent to savings of 98.7 thousand tons of oil and 319 thousand tons of CO2,eq. The market-driven mechanism is associated with cost-to-benefit ratios, construction businesses, types of building architecture, degree of urbanization and household composition. The strong wind load of typhoons is another major concern. For sustaining the solar thermal industry in Taiwan, the dominant factor for disseminating SWHs in metropolitan areas involves developing building-integrated solar thermal systems. Alternative financial incentives are required for industrial heating processes in the commercial sector.

“…Several factors influence hot water use patterns in different countries, including the lifestyle, climate, household size, age of family members and the required temperature at the point of use [5][6][7][8][9]. In Taiwan, a general survey of users was conducted by Chang et al [10][11][12]. In terms of A SC , solar water heaters were categorized into three groups as shown in Table 1.…”

“…Furthermore, Chang et al [12] indicated that unit price of a SWH decreases with larger area of solar collectors installed. The payback period of residential SWHs with the current subsidy program was about 5-6 years in Taiwan [11]. However, the payback period is also associated with solar insolation, energy price and η of a SWH.…”

Abstract:To develop indigenous alternative and renewable energy resources, long-term subsidy programs (1986-1991 and 2000-present) for solar water heaters have been enforced in Taiwan. By the end of 2010, the total installed area of solar collectors had exceeded 2 million square meters. However, over 98% of solar water heaters were used in residential systems for hot water production, with the areas of installed solar collector being less than 10 square meters. There were only 98 systems with area of solar collectors installed exceeding 100 square meters put into operation from 2001 to 2010. These systems were mainly installed for water heating in dormitories, swimming pools, restaurants, and manufacturing plants. In the present study, a comprehensive survey of these large-scale solar water heaters was conducted. The objectives of the survey were to assess the system performance and to collect feedback from individual users. It is found that lack of experience in system design and maintenance are the key factors affecting reliable operation of a system. Hourly, daily and long-term field measurements of a dormitory system were also examined to evaluate its thermal efficiencies. Results indicated that thermal efficiency of the system is associated with the daily solar radiation. Hot water use pattern and operation of auxiliary heater should be taken into account in system design.

“…The accumulated area of solar collectors installed at the end of 2012 reached 2.25 million square meters (275 m 2 per thousand inhabitants). Chang et al [9] further demonstrated that the market-driven mechanism for SWHs in Taiwan is a multi-parametric phenomenon. In addition to the capital cost of SWHs and energy price index, the potential market is associated with the population structure, urbanization, type of housing and status of new construction.…”

Solar water heaters represent the success story in the development of renewable energy in Taiwan. With increasing public awareness, there are over 0.3 million residential systems in operation. To disseminate solar water heaters in remote islands, economic feasibility and water quality are taken into account in this study. The payback period in Kinmen and Penghu Counties are evaluated, according to effective annual solar energy gain, hot water consumption pattern and cost. Assessment of the scaling and corrosion tendencies for solar water heaters using tap and underground water are also presented. For flat-plate solar collectors with metal components, favorable corrosion resistance and protective anti-corrosion coatings are required.
