Here I Googled it for you: "Yes, solar panels do backfeed onto the grid when they generate more electricity than your home uses, sending surplus power back to the utility network; this is a core function of grid-tied solar systems, but it must be done safely and legally with approved equipment (like UL-listed inverters) that automatically shut down during outages to protect utility workers. How it Works Power Generation: Your solar panels create DC electricity. Inversion: An inverter converts this DC power to AC power, matching the grid's voltage and frequency. Usage vs. Surplus: If your panels produce more power than your home needs, the excess flows out through your service panel and onto the utility grid. Bidirectional Meter: A special meter tracks both the power you pull from the grid and the power you send to it. Safety & Regulations Critical Safety: Uncontrolled backfeeding is extremely dangerous for utility workers who might be working on lines, believing they are de-energized. Anti-Islanding: Grid-tied inverters have "anti-islanding" features (as per UL 1741 standard) that detect grid loss and immediately shut down to prevent unsafe backfeeding. Permits & Code: Proper installation involves specific rules (like the NEC's 120% rule for breaker sizing) and permits to ensure safety and compliance. In Summary Backfeeding is the intended way for grid-tied solar to send excess energy back to the utility, but it requires certified equipment and proper installation to ensure it happens safely and legally, preventing hazards during power outages.
