How long will it last?

 

The lifespan of a solar array, which includes the solar panels, inverter, and other components, can vary, but here’s a general breakdown:

1. Solar Panels

  • Lifespan: Solar panels typically last 25 to 30 years. After this period, they may still function, but their efficiency in converting sunlight to electricity decreases. Most manufacturers offer warranties that guarantee at least 80% of the original energy production for 25 years.

  • Degradation Rate: Solar panels degrade over time, losing about 0.5% to 1% of their efficiency per year. This means after 25 years, a panel might operate at about 75-85% of its original efficiency.

2. Inverters

  • Lifespan: Inverters generally last between 10 to 15 years. Since they are the components responsible for converting DC to AC electricity, they experience more wear and tear and may need replacement once or twice during the lifespan of the solar panels.

  • Types: String inverters tend to have a shorter lifespan compared to microinverters or power optimizers, but this can vary depending on the specific product and usage conditions.

3. Other Components

  • Mounting Systems: The racks and mounts that hold the solar panels in place are typically made of durable materials like aluminum or stainless steel and can last for the life of the solar panels, often 25-30 years or more.

  • Wiring and Cables: These components can also last 25 years or more but may need inspections and maintenance to ensure they remain in good condition.

4. Maintenance and Durability

  • Maintenance: Proper maintenance, including regular cleaning and inspection, can extend the life of a solar array. Dust, debris, and shading can impact the efficiency of the system, but these issues are usually manageable with regular care.

  • Durability: Solar panels are designed to withstand harsh weather conditions, including hail, snow, and high winds. They are typically tested and certified to endure these elements, contributing to their long lifespan.

5. End-of-Life

  • Recycling: At the end of their life, solar panels can be recycled, and efforts are increasing to improve the recycling processes for solar materials, making solar energy more sustainable.

Conclusion:

In summary, while solar arrays are a long-term investment with a lifespan of 25 to 30 years, the efficiency and performance of the system will gradually decline over time. Regular maintenance and occasional replacement of certain components, like inverters, are necessary to maximize the system's longevity and effectiveness.
