Abstract
The technology of photovoltaic (PV) systems is improving continuously in relation to their cost and performance, so their use is increased considerablyPV systems today are quite reliable in the different applications. The use of PV’s as the electrical power source for a residence has reducing the need for electricity. Refrigerators, air conditioners, electric water heaters, electric ranges, electric dryers, and washing machines are all large users of electricity [7]. Alternative sources of energy are available to greatly reduce the use of electrical energy. In this paper, we are focused on the concept of installation solar photovoltaic (PV) system that generally requires engineering services for each individual application. There is relevant information regarded to PV systems stand-alone (off - grid) or grid connected (on - grid) ones. On the other hand there are a lot of guidelines on the subject of the design process of a PV system such as: the calculation of the electrical load, the size of the PV System, PV subsystems – inverters, controllers, wiring, mounting PV panels, batteries, types of photovoltaic cells [1]. The purpose of this paper is to show how PV panels can be used on the environments of a public institution in Albania conditions, in particular in one of the Albanian University (UET). The results of the study will be based on accurate calculation of installed solar panels and initial cost of their installation. Furthermore, in this paper it will also discuss the main advantages and disadvantages of implementing of this contemporary technology in our country. DOI: 10.5901/ajis.2015.v4n2p67
Highlights
The daily life issues like High prices of electric power supply Saving the Earth resources Environmental protection Make the use of solar energy really imperative
Even the European University of Tirana will certainly profit from this research after the installation of a similar system
The main objective of the study is to make the economic analysis and to note the benefits obtained from the use of the solar energy for the European University of Tirana and for all Educational Institutions in Albania
Summary
The main objective of the study is to make the economic analysis and to note the benefits obtained from the use of the solar energy for the European University of Tirana and for all Educational Institutions in Albania. The significance of the study is related to the improvement of these aspects: → The low cost for power supply in the Institution. → Absence of technical failure as the ones randomly happening when power supplied by the national net. At the end of the elaboration project, the Institution will have e new alternative source of electric energy
