The tremendous impact of solar energy and SWEA as alternatives for renewable energy sources has received world wide attention since few decades. Modern people prefer to have a “go green” concept in utilizing the energy. At this juncture, solar invertersand SWEA invertors are critical. Energy self sufficiency is an important concern of governments across the globe. Hence the renewable energy sources such as solar energy and wind energy are widely accepted. Most of the people are unaware of the components of the renewable energy systems. The basic principle behind solar energy utilization is trapping solar energy by solar panels and produces a DC electric current.
