| Abstract [eng] |
The present study investigates the usage of solar energy for the household needs and for hot water heating depending on the rate of return. the introduction contains information about the relevance of the topic, goals and objectives of the present investigation. The theoretical part of the research includes information about the properties of renewable energy sources, solar radiation, the effect of solar energy plants on the environment, as well as the advantages and disadvantages, efficiency and installation stages of these plants.In the present analysis the need of home energy for general purposes and predictable qauntity of solar energy production have been calculated. Moreover, the solar modules and inverter have been selected. The present analysis also demonstrates the economic evaluation and payback time. In the second research section, the need of energy for general purposes and hot water heating has been calculated. The economic assessment and payback time are also shown. Finally, the present study includes the conclusions and results of the investigation and a more useful project, according to the rates of return, is chosen. |
