  1. 30 years or more ✔
  2. About 5 years
  3. About 10 years

Why: Panels have no moving parts, so they keep working long after repaying the energy used to make them. That long life makes solar a decades-long investment.

Huh, didn't know that: EIA notes some types of PV cells contain heavy metals that need special handling when retired.
