Solar Panel Lifespan: A Long-Term Investment
Typically, solar panels have a warranty of 25-30 years. However, with proper maintenance and high-quality installation, they can often go on producing even longer. 
Factors Affecting Solar Panel Lifespan:
- Quality of Panels: High-quality panels from reputable manufacturers tend to have longer lifespans.
- Installation: Proper installation ensures optimal performance and longevity.
- Maintenance: Regular cleaning and 5 year inspections can help maintain efficiency and extend the lifespan.
- Environmental Factors: Extreme weather conditions like hail or excessive heat can impact the lifespan.
How Solar Panels Degrade Over Time:
While solar panels are incredibly durable, they do experience a gradual degradation over time. This degradation, measured in terms of power output, is typically around 0.25% to 1% per year. This means that after 25 years, a solar panel might produce around 80% of its original power.
