SOLAR ENERGY SOLARENERGY We get most of our energy from the sun. We call it solar energy. It travels from the sun to the earth in rays. Some are light rays that we can see and we can’t see, like x-rays. The sun is a giant ball of gas. It sends out huge amounts of energy every . Most of the energy goes off into space. Only a small part reaches the earth. Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with ...
1 Demand for electricity is growing day by day Power generation is not up to the mark Deficit about 6-8% in India Need for developing alternatives to reduce power deficit Power generation through rooftop solar is considered as the best alternative Solar has some drawbacks Net metering is the solution for those drawbacks 3 Why net metering is required? Solar power is not continuous Expensive batteries are needed Backup generators are required Cannot be transported to long distances Fig .1 4 What is Net Net metering is a billing mechanism that metering? credits solar energy system owners for the electricity ...
Solar energy Solar energy is the radiant light and heat from the Sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation along with secondary solar resources such as wind and wave power, hydroelectricity and biomass account for most of the available renewable energy on Earth. Only a minuscule fraction of the available solar energy is used. Solar power provides electrical generation by means of heat engines or photovoltaics. Once converted, its uses are limited only by human ingenuity. ...
