“…When loans and subsidies are considered, net present value varies between 1222.60 and 2034.53 Euro, simple payback period between nine and eight years and internal rate of return between 22% and 52% [28]. The financial analysis of SWH systems installation in six cities from Serbia showed that 20% subsidy is justified already by CO 2 mitigation potential of SWH systems, while 50% subsidy reduce payback period to 5.5-6 years [30].…”

“…However, they still have a higher initial cost than conventional water heating systems, this being a major obstacle to its adoption by low income families and leading to the need for an economic analysis of this system. For this reason, many government authorities have created public policies to encourage the use of these technologies primarily among the low-income population [5,[28][29][30].…”

Solar water heating (SWH) systems can provide a significant part of the heat energy that is required in the residential sector. The use of SWH systems is motivated by the desire to reduce energy consumption and especially to reduce a major source of greenhouse gas (GHG) emissions. The purposes of the present paper consist in: assessing the solar potential; analysing the possibility of using solar energy to heat water for residential applications in Romania; investigating the economic potential of SWH systems; and their contribution to saving energy and reducing CO 2 emissions. The results showed that if solar systems are used, the annual energy savings amount to approximately 71%, and the reduction of GHG emissions into the atmosphere are of 18.5 tonnes of CO 2 over the lifespan of the system, with a discounted payback period of 6.8-8.6 years, in accordance with the savings achieved depending on system characteristics, the solar radiation available, ambient air temperature and on heating load characteristics. Financially, the installation of SWH systems determines net savings of 805-1151 Euro in a 25-year period in the absence of governmental subsidies. According to the sensitivity analysis, installing a SWH system with subsidies of up to 50% determines the reduction of the discounted payback period to 3.1-3.9 years and the increase of net savings to 1570-1916 Euro. These results indicate that investing in these systems is cost-effective for Romanian households as long as the governmental subsidies increase.

“…Stevanovic and Pucar (2012) noted that a 20% purchase-based subsidy is considered to be an appropriate subsidy level that makes SWHs financially more attractive in comparison with conventional electric or gas water heaters. However, Roulleau and Lloyd (2008) also pointed out that increasing the total number of systems may not result in real energy savings over the lifespan of the systems.…”

Incentives to using solar thermal energy in Taiwan

A national subsidy program is one of the key elements for translating customer choice into a larger market share for renewable energies. Since solar water heaters (SWHs) are a cost-effective and mature technology, purchase-based subsidy programs have been sponsored by the Bureau of Energy, Ministry of Economic Affairs (BEMOEA) in Taiwan. The market of SWHs is associated with economic factors, population characteristics, degree of urbanization (available roof space), and climatic conditions. Regional programs have also affected the growth in sales. However, the penetration rates are still low, and the local market has changed little in recent years. Thus, the timing of the termination of the long-duration subsidy program is a subject of debate. In this study, a new scheme in the residential sector is proposed in the period of 2016 to 2019. In addition, small and medium enterprises (SMEs) make up the majority of Taiwanese companies. Most SMEs suffer from insufficient capital to support their commercial activities. To prompt solar thermal energy in the commercial sector, the energy service company (ESCO) business model can be adopted. The same feed-in tariffs for PV systems can be granted for SWHs and photovoltaic/thermal (PVT) systems with performance-based subsidies to end users or ESCOs.

“…Stevanovic and Pucar [4] have estimated the performance of solar water heating system with the f-Chart method. The results of theoretical analysis have been used to determine the level of the subsidy should be offered by the Serbian government to increase the popularity of renewable energy sources (RES) in this country.…”

Abstract. The solar domestic hot water (SDHW) system located on the campus of Bialystok University of Technology is the object of the research described in the current paper. The solar thermal system is composed of 35 flat plate collectors, 21 evacuated tube collectors and eight hot water tanks with the capacity of 1 m 3 of each. Solar facility is equipped with hardware for automatic data collection. Additionally, the weather station located on the roof of the building provides measurements of basic parameters of ambient air and solar radiation. The main objective of Regional Operational Program was the assessment of the effectiveness of this solar energy technology in the climatic conditions of the north-eastern Poland. Energy efficiency of SDHW system was defined in this research as the ratio between the useful heat energy supplied to the domestic hot water system and solar energy incident on the surface of solar panels. Heat loss from water storage tanks, and from the pipe network to the surrounding air, as well as the electrical energy consumed by the pumps have been included in the calculations. The paper presents the detailed results and conclusions obtained from this energy analysis.
