Renewable energy sources are rapidly becoming an integral part of worldwide measures to combat the effects of climate change. In 2016, the annual energy yields worldwide from wind power, solar thermal heat and photovoltaic power were 990 TWh, 375 TWh and 375 TWh, respectively. Other than public awareness, financial incentives are vital to the promotion of renewable energy sources. In Taiwan, solar radiation ranges from 1,200 to 1,700 kWh/m2/year. The government of Taiwan promotes the use of solar thermal energy. Two purchase-based subsidy programs for solar water heaters (SWHs) have been implemented during the periods 1986?1991 and 2000?2018. Some regional programs have also been initiated. During the second subsidy program, the cumulative area of solar collectors that was installed was approximately 2.61 million square meters by the end of 2017 and more than 93% of these were installed in the domestic sector. This study addresses the effectiveness of the incentive programs. A multi-parametric mechanism associated with financial incentives, climatic conditions, the status of new construction, the type of architecture and household composition is also presented. For future solar applications in Taiwan, it is proposed that research and incentive programs associated with, building-integrated solar thermal (BIST), photovoltaic/thermal (PV/T), and industrial heating processes should be implemented.
