Solar Inverter

Solar energy is free and clean. There is enough for everyone, and we will never run out of it. Solar energy is renewable. The sun will keep making energy for millions of years .Why don’t we use the sun for all our energy needs? We don’t know how to yet. The hard part is capturing the sunlight. It shines all over the earth and only a little bit reaches any one place. On a cloudy day, most of the light never reaches the ground at all.Lots of people put solar collectors on their roofs. Solar collectors capture the sunlight and turn it into heat. People can heat their houses and their water using the sun’s energy.Solar cells can turn light energy into electricity. Some toys and calculators use solar cells instead of batteries. Solar panels are made of many solar cells. Some people put solar panels on their home. These solar panels can make enough electricity for a house. Solar panels are good for houses and buildings without access to power lines.We can power our house by using solar panels by placing them on the roof and then connected to the battery and the battery is connected to the inverter. a solar inverter is a piece of the solar energy puzzle. Its purpose is to change the direct current electricity that is generated from a photo voltaic panel into an alternating current that can be used by in-home appliances and the community electricity grid. Because all photo voltaic panels produce electricity in DC, an inverter is required for all solar power systems to make the electricity usable.This project uses regulated 5 V; 500 ma power supply. A 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12 V step down transformer.
