Do solar panels work during a blackout?

Standard solar panels STOP generating during a blackout — anti-islanding protection disconnects them for safety. Solar + battery with backup (EPS) capability keeps essential circuits running: fridge, lights, router, phone charging. Tesla Powerwall offers whole-home backup. GivEnergy provides partial backup via EPS port. UK blackouts average 1 per year lasting 30-90 minutes — backup is peace of mind, not a financial necessity.
