Efficiency of polycrystalline photovoltaic parks in Romania: Possibility of using renewable energy

Abstract

The performance of photovoltaic panels and lifetime are determined to a large extent by the quality of photovoltaic cells, their soldering technology, the quality of ethyl vinyl acetate film in which they are encapsulated, the encapsulation technology and the back sheet. Depending on the manufacturing technology, photovoltaic panels can be made of monocrystalline, polycrystalline, and amorphous silicon cells. This manuscript studies the main factors that influence the aging of photovoltaic panels in order to assess their effectiveness and sustainability in terms of energy, in order to establish the optimum conditions of photovoltaic panel?s location, being a contribution to the attainment of the targets in terms of growth using renewable sources of energy. The main purpose of this research is to study the current state, in Romania, in the field of renewable energies by using solar panels.
