Can a cracked solar panel still be used? A detailed explanation of four levels of damage.
1. Causes of cracks: Hail impact, thermal stress, installation pressure, handling bumps, aging. 2. Four-step assessment: Check crack location/shape/whether it is expanding/whether it affects power generation. 3. Level 1: Minor: Fine scratches/hairline cracks, impact <5%, no treatment required, continue use. 4. Level 2: Moderate: Obvious cracks that do not penetrate, impact 5%-15%, requires continuous observation. 5. Level 3: Severe: Through-crack/glass shattered, impact 15%-50%, must be replaced. 6. Level 4: Completely broken/frame detached, immediately disconnect power and replace.
