Because a Grid-Tied Solar System does not require batteries and other equipment to use battery storage energy, it will lower equipment and installation cost allowing you to save more money with solar panels through better efficiency rates and net metering. Grid-tied solar systems are generally cheaper and very simple to install.

Solar panels often generate more electricity than you are capable of consuming and because of net metering, excess electricity is put onto the utility grid. Net metering is a very important role in how solar power is incentivized. Many utility companies are committed to buying electricity from homeowners at the same rate as they sell it themselves.
