To overcome energy crisis and global warming, the SPV (Solar Photovoltaic) systems have attracted significant attention in recent years. Besides being emission-free, the energy coming from the SPV energy is available in abundance in the nature. In addition, it offers a solution for power supply in remote areas which are not accessible by the utility grid, and in the countries that lack in fossi...
