Apart from a product warranty, you also get a yield warranty for SOLARWATT photovoltaic systems and individual components. Depending on the product, the warranties differ with regard to the covered period and conditions.

The product warranty covers the solar modules supplied by SOLARWATT against faulty materials and workmanship that could negatively affect their functionality.

With the yield warranty SOLARWATT assures you of a minimum output over a specified period of time.
