Lifespan of polycrystalline and monocrystalline solar panels

How long do polycrystalline panels last?

Polycrystalline panels provide decent efficiency (13-16%) and have a lifespan of around 25-35 years. They are a budget-friendly option suitable for larger spaces, offering a cost-effective alternative to monocrystalline panels. Thin-film panels are the most affordable and flexible option, with lower efficiency (7-18%) and a lifespan of 10-20 years.

What is the difference between monocrystalline and polycrystalline solar panels?

Monocrystalline panels offer the highest efficiency (15-20%) and have a long lifespan of 40 years or more. They are ideal for installations with limited space and a need for high performance, despite being more expensive. Polycrystalline panels provide decent efficiency (13-16%) and have a lifespan of around 25-35 years.

How efficient are polycrystalline solar panels?

Polycrystalline solar panels have an efficiency of 13% to 16%. This efficiency shows how well the panels are able to turn sunlight into electricity. Polycrystalline panels demonstrate a marginally reduced efficiency when compared to monocrystalline solar panels, which showcase efficiency ratings varying from 15% to 25%.

How long do monocrystalline solar panels last?

Each wafer forms a solar cell. This uniform crystal structure gives monocrystalline panels their distinct dark, almost black appearance. Monocrystalline panels are built to last. Most manufacturers offer a 25 to 40-year performance warranty.
