A typical grid-tied solar power system includes three parts: the photovoltaic solar panels on the roof, a rack that holds those panels, and a solar inverter that converts the solar power into something usable in your home.
Once installed, a grid-tied solar power system instantly begins producing electricity, powering all your home appliances, including the fridge, the television, the lights, even the boiler. Any existing electrical connection can be powered by the grid-tied solar energy system.
This solar power supplements your existing power grid connection, instantly reducing your demand and reliance on your utility company and cutting down on your overall electricity bills.
If the sun isn’t shining or you experience higher-than-expected demand, a grid-tied solar power system can also draw on the grid as usual, ensuring you always have a back-up source of power.
Grid-tied solar power systems are, generally, the most cost-effective and easy-to-install of the three main types of solar power grids, making them one of the most popular of the three main types of solar power systems.
