When comparing monocrystalline (mono) solar panels and polycrystalline (poly) solar panels in terms of service life, there is generally no significant difference between the two types.

Both monocrystalline and polycrystalline solar panels typically come with two warranties: a physical warranty and an efficiency warranty. The physical warranty typically spans 15 to 30 years and covers any physical damage that may occur to the panels. The efficiency warranty, on the other hand, extends for 20 to 30 years and pertains to the panels' efficiency after 25 years of operation. For instance, if an 80% efficiency warranty is stated after 25 years, it means that the panels will still produce 80% of the electricity they generated in their first year after 25 years. Despite producing slightly less energy, the panels will still function effectively.

It's important to note that the duration of these warranties is determined more by the manufacturer rather than the specific panel technology, whether monocrystalline or polycrystalline. Therefore, when considering the service life of solar panels, it's essential to evaluate the warranties offered by different manufacturers, as they may vary. Ultimately, the choice of manufacturer plays a significant role in ensuring the best warranties and service life for your solar panels.
