What is grid tied solar power system?
Grid-tied, on-grid, utility-interactive, grid intertie and grid backfeeding are all terms used to describe the same concept – a solar system that is connected to the utility power grid.
In the day time,the solar system generate electricity which is used to the electrical appliance,if the electricity is not enough,it can get power from utility power grid.If the power generated is above the power consumed,it can sell power to the utility power grid(if the government allows)
Advantages of Grid-Tied Systems.
1. Save more money with net metering
Your solar panels will often generate more electricity than what you are capable of consuming. With net metering, homeowners can put this excess electricity onto the utility grid instead of storing it themselves with batteries.
2. The utility grid is a virtual battery
The electric power grid is in many ways also a battery, without the need for maintenance or replacements, and with much better efficiency rates. In other words, more electricity goes to waste with conventional battery systems.
Components include solar panel,inverter,PV bracket,wire and some other accessories.
