Example of cost effectiveness of individual solar collector installation and its contribution to the environment protection

摘要

This paper shows an example of installing solar panels as a support for domestic hot water and space heating, with the calculation of the investment's cost effectiveness and its contribution to the environment protection. The goal is to use solar energy for household needs and so reduce pollution resulting from the use of traditional fossil fuels for heating water and space. This research has resulted from a high intensity of solar radiation and the large number of sunny days per year in the observed area. The object of the analysis is an apartment in the territory of Podgorica, Montenegro, which serves as an example for the analysis of buildings with similar characteristics. In the first part of the paper an overview of the current situation and the reason for the realization of such endeavors is shown; analysis of the architectural and climatic conditions for the use of solar energy define the necessary activities and the main expectations from this investment are presented. The second part describes the components of the solar system with all installations, indicative budget and required amount of electricity for water heating and space are calculated and eventually the whole project is observed from an economic point of view to determine the return on investment.
