Subsidy Programs

Government intervention in the form of financial incentives is crucial for translating customer choice into a larger market share for solar thermal applications. The lengthy subsidy programs for solar water heaters in Taiwan have expanded the local market. On a remote island (Kinmen County), the area of solar collectors that are installed per 1000 inhabitants is 192.9 square meters. This study investigates a market-driven mechanism in terms of disposable income, household structure, building type and financial viability. The dual subsidy programs appear to have distorted the local market. The cumulative energy savings for solar water heaters that are installed is misleading because the systems are over-designed and there is a high replacement rate (or shorter service period).

Solar Water Heaters

Solar water heaters (SWHs) are one of the most effective plans for general and easy use of solar energy to supply hot water in domestic and industrial sectors. This paper gives the first-ever attempts to assess the optimal localization of SWHs across 22 major cities in Zambia, as well as determine the possibility of hot water generation and model the greenhouse gas (GHG) emission saving. The climate data used is extracted by using the MeteoSyn software which is modeled in TSOL™. Results show the high potential of GHG emission reduction due to nonconsumption of fossil fuels owing to the deployment of SWHs, and three cities Kabwe, Chipata, and Mbala had the highest GHG mitigation by 1552.97 kg/y, 1394.8 kg/y, and 1321.39 kg/y, respectively. On average, SWHs provide 62.47% of space heating and 96.05% of the sanitary hot water requirement of consumers. The findings have shown the potential for the deployment of SWHs in Zambia. The techno-enviro study in this paper can be used by the policymakers of Zambia and countries with similar climates.
