Bearing in mind that the panel does not have mobile parts and that the cells and contacts are encapsulated inside a strong synthetic resin, a very good reliability is achieved together with a long service life of around 30 years or over.

As a matter of fact, the main manufacturers of solar modules offer guaranties of their products of about 20 to 25 years.

Besides, if one of the cells fails, it does not affect the operation of the others and the intensity and voltage produced can easily be adjusted adding or removing cells.
