With a solar system for home it is possible to harness sunlight and convert it to electricity for every day use. Photovoltaic cells or solar panels are made of semiconductor materials which are sensitive to sunlight and causes electrons to flow through the cell to generate electricity, they absorbs photon and release electrons.
Solar systems may be used for the home or residential setting to generate DC power which is converted to AC power for general use. Solar panels are typically mounted on roof tops or located of optimal exposure to the sun.
The solar system for home meter measures the amount of electricity provided to your home by your local utility. When your solar modules produce more electricity than you are using, it goes back to the utility company’s grid, crediting your account.
The sun doesn’t always shine which is arguably the biggest problem with solar panels and storing energy from the sun during the day in batteries to be used at night is terribly inefficient, quite a considerable amount of energy is lost during that process. Some have considered pumping water up a hill during the day and using the flow of water downhill to move turbines and generate electricity, however this has also proved to be inefficient. Water has also been heated during the day and the steam used the turn turbines at night to provide constant electricity, salt however has proved to be more efficient and only looses about 8 percent of energy during the process when heated. Molten salt stores heat at a high temperature and then used later to generate continuous electricity by some solar power plants. At home what typically happens is that any excess electricity that is generated is sold or credited to the home owner’s account then can be used when required.
