Lifespan of polycrystalline silicon and monocrystalline silicon solar panels

How long do monocrystalline solar panels last?

Most monocrystalline solar panels come with 25 or 30 years warranties. However, you can expect your system to last for up to 40 years or more. How Long Do Polycrystalline Solar Panels Last? Polycrystalline PV cells have a slightly higher degradation rate than, which causes them to lose their efficiency a little faster than the monocrystalline ones.

How long do solar panels last?

Both monocrystalline and polycrystalline solar panels generally have an average lifespan of 25+ years. However, while considering the lifespan of solar panels, you should always look for companies that offer better power production warranty.

How long do polycrystalline PV cells last?

Polycrystalline PV cells have a slightly higher degradation rate than, which causes them to lose their efficiency a little faster than the monocrystalline ones. Don’t get me wrong, they still have a lifespan of 20-35 years and sometimes even more.

Are monocrystalline solar cells better than polycrystalline solar panels?

In terms of aesthetics, monocrystalline solar cells are superior to polycrystalline panels. The black hue and discreet look of the mono solar panels look aesthetically pleasing. On the other hand, polycrystalline appears to have a blue hue and a non-uniform structure.

What is a polycrystalline solar panel?

The polycrystalline solar panel or “multi-crystalline” panels are also composed of the same materials i.e. silicon, but the process of manufacturing the cells is much simpler as compared to monocrystalline cells. Unlike monocrystalline cells, polycrystalline cells are not made from a single crystal of silicon.

How much does a polycrystalline solar panel cost?

Polycrystalline panels, on the other hand, cost around £280 per m², or £562 for a 350 W panel. This is partly because producing single-crystal silicon – used in monocrystalline panels – is a long, complicated process.
