The book gives a detailed information about Solar Energy and Analysis of Solar Inverter Circuit on different FPGA. Different I/O standards has been considered for the power analysis of solar inverter circuit such as HSTL, GTL, SSTL, LVDCI. The book also gives a brief information about the different I/O standards considered for the analysis. Solar power is a type of energy which is harnessed from sun light and heat using very innovative technologies using solar heating, solar photovoltaic's, solar thermal energy. Solar energy is a renewable energy which is defined as energy generated from natural resources such as sunlight, water, wind and geothermal heat. Solar energy is the most readily available and non - polluting energy. The development of solar energy technologies will make a huge contribution to Country's economic section. This will also provide a substitute to fossil fuel which will help us to preserve our natural resources for future generations.
