Lifespan of solar monocrystalline silicon panels

What are monocrystalline solar panels?

Monocrystalline solar panels are made with wafers cut from a single silicon crystal ingot, which allows the electric current to flow more smoothly, with less resistance. This ultimately means they have the highest efficiency ratings, longest lifespans, and best power ratings on the market, ahead of all other types of solar panels.

How long do polycrystalline solar panels last?

Like their monocrystalline counterparts, polycrystalline panels also come with impressive 20 to 35-year performance warranties. Their expected functional life is also typically within that range, making them a very dependable choice for long-term energy generation.

How long do monocrystalline panels last?

Monocrystalline panels are built to last. Most manufacturers offer a 25 to 40-year performance warranty. This means they guarantee the panel will still produce a high percentage (often 80% to 85%) of its original power output after that many years.

Are polycrystalline solar panels a good choice?

Their expected functional life is also typically within that range, making them a very dependable choice for long-term energy generation. Polycrystalline panels generally have a slightly higher degradation rate than monocrystalline panels, usually around 0.5% to 0.8% per year.
