Grid-tied solar electric systems utilize PV modules and inverters to deliver clean electricity.
Grid-tied PV systems avoid the need for batteries, which create additional expense and maintenance. The tradeoff with a grid-tied system is that there is no stored energy in the home – at night, on a cloudy day, or during times of high use, electricity is purchased from the grid.
It is possible to install a system that offsets all of your electricity consumption through the net metering arrangement described above. Since these systems are modular, a smaller system can be installed based upon your budget or site limitations.
