[pdf] Solar panels feed back into the grid through net metering. The energy provider then gives the homeowner a credit on their utility bill for the exported electricity. The grid-tied inverter matches grid voltage and frequency. Settlement follows local policy. How grid-tied solar feeds power back I am Wao Wu, Co-founder and Sales. . Self-consumption beats exports – Maximizing the solar electricity you use directly in your home typically provides better financial returns than exporting excess to the grid, especially with time-of-use rates and battery storage becoming more common in 2025. The utility company prepares for this process daily when the sun rises. Connecting to the grid allows you to take advantage of net metering, which can significantly reduce your electricity bills by crediting you for the excess energy your system generates.
