ECONOMIC EFFICIENCY OF A THERMOSOLAR SYSTEM.
A CASE STUDY
Integration costs of a thermal solar system for domestic hot water preparation are a decisive factor regarding the implementation of the system. Integration cost depends on the size, capacity, complexity and the type of the thermal solar system. The payback period is directly influenced by the costs of conventional energy prices. Thus, this paper estimates the economic efficiency or the payback period of a thermal solar system for a household with three persons. The thermal solar system is chosen based on the three-year average monthly water consumption. The payback period is estimated based on the last three year monthly average costs of natural gas consumption.
