What surge protection should I have?

Minimum: Type 2 SPD (Surge Protection Device) — included in most modern inverters. Recommended: Type 1+2 SPD on both DC and AC sides — installed in your consumer unit. Cost: £150-£300 extra.

What happens if lightning strikes near my home?

The surge protection in your inverter absorbs the voltage spike. In rare cases, the inverter may shut down and need resetting. Panel damage from nearby lightning is extremely rare.

Does my insurance cover lightning damage?

Yes — standard home insurance covers lightning damage to your property and solar panels. Check your policy includes solar panels (most do, especially if you notified your insurer of the installation).

Should I disconnect panels during a thunderstorm?

No — the system handles this automatically. Surge protection absorbs spikes, and the inverter disconnects from the grid if it detects anomalies. No manual intervention needed.

Do solar panels attract lightning?

Solar panels do NOT attract lightning — this is a common myth. Lightning strikes the highest point in an area regardless of whether solar panels are present. Your panels are no higher than your existing roof ridge. Facts: (1) Panels are NOT conductors that attract lightning (silicon and glass are insulators). (2) Modern inverters include Type 2 surge protection as standard. (3) Electricians can add Type 1+2 surge protection for extra safety (£150-£300). (4) Solar installations must comply with BS 7671 wiring regulations, which include earthing and surge protection requirements. (5) In the UK, lightning strikes homes approximately 1 in 10,000 per year — solar panels do not change this probability.
