As the worldwide demand for electricity increases and the historical reliance on fossil fuels is being challenged by increasing environmental awareness, the focus has turned to renewable energy sources. As a reliable and versatile form of renewable energy, solar PV systems are expected to become a dominant energy source. According to market research, PV is expected to account for over 50% of the world’s total electricity generated by renewable energy sources by 2070. Solar is a promising source of future energy supplies because not only is it clean, it’s remarkably abundant.
