Standard grid-tied solar systems shut down automatically during a power cut for safety reasons, this is to protect engineers working on the grid lines. Your panels will resume generating as soon as the grid power is restored. If you need backup power during outages, you can install a hybrid inverter with battery storage that isolates your home from the grid and continues supplying electricity from the battery and panels. This emergency power supply (EPS) feature is available on most modern hybrid inverters and is worth considering if you experience frequent power interruptions.

With a cost of £6,600-£8,500 (0% VAT included) and savings of £547+ per year based on Abercarn's solar yield of 768 kWh/kWp at current electricity rates of around 25p/kWh, plus Smart Export Guarantee income of around 13-15p/kWh for surplus electricity, a typical solar system in Abercarn pays for itself in 11-13 years.

Adding a battery extends self-consumption and can reduce payback further if you use most electricity in the evenings. Total lifetime savings typically reach £15,000-£18,000 depending on your usage pattern.
