Solar panel and health myths: do they emit harmful radiation?

Internet is full of claims that solar panels 'emit cancer-causing radiation' or 'interfere with pacemakers'. What science says: none of that. But confusion is understandable. The facts.

Types of emitted radiation

Panels themselves: zero electromagnetic radiation. They're passive photodiodes. The inverter: emits low-frequency (50-60 Hz) and radiofrequency (RF) waves from electronic switching. Level: similar to a washing machine or microwave.

Measured levels vs legal limits

5 kW inverter at 3 ft: 0.1-0.3 microtesla. ICNIRP (WHO) limit: 100 microtesla. You're 1000× below the limit. Compared to: microwave in use (5 µT at 20 in), hair dryer (10 µT), phone to head (50 µT).

Pacemaker myth

Medical studies (Mayo Clinic, Cardiology Society 2018): solar inverters do NOT interfere with modern pacemakers at distances >12 in. Most homes have the inverter in garage, away from living areas.

False cancer link

Hoax originated in 2018 from social disinformation. NO epidemiological study (including large 2020-2024 meta-analyses) shows correlation between solar panels and cancer. WHO classifies low-frequency EMF as 'possibly carcinogenic' but requires levels 100× higher than panels'.

Solar reflection and birds

Lesser myth: 'panels blind aircraft and burn birds'. Truth: panels have anti-reflective coating (>96% absorption). Only concentrating solar thermal (not PV) plants have that issue, and only at utility scale.

REAL risks (these exist)

1) Falling off the roof during install (occupational, not electrical). 2) Electric shock from untrained handling. 3) Fire from bad-crimped cable. These are real. 'Radiation' isn't.

Combine with EMI interference.
