I. Introduction
Now, at the present time, renewable energy sources are playing an increasingly important role because they can be renewed on a human scale and their use is much more environmentally friendly than that of their non-renewable counterparts. That is why more and more attention is being paid to the promotion and understanding of these energies and more and more research and development is being devoted to their use. In our case, solar panels are no exception to what has just been said, as there are more and more scientific articles and journals on the development of photovoltaic panels and their potential efficiency.
