A performance guarantee for solar panels is a guarantee provided by the manufacturers on the performance of the solar panels. This guarantee means that the solar panels will deliver a certain performance within a certain period of time.

The performance guarantee usually covers the lifetime of the solar panels, which is usually 25-30 years. This means that manufacturers commit that the solar panels will deliver at least a certain performance during the guarantee period. This performance is usually a percentage of the rated output of the solar panels, for example 80%.

The performance guarantee plays an important role when buying solar panels, as it ensures that the solar panels will continue to work efficiently over the long term. If the performance of the solar panels decreases during the warranty period, the manufacturer is obliged to repair or replace the solar panels.

It is important to note that the performance guarantee only covers the performance of the solar panels and does not cover other possible faults or failures. It is therefore important to buy solar panels from reliable manufacturers who offer good quality products.

Overall, the performance guarantee is a very important consideration when buying solar panels. This ensures that the solar panels will work efficiently over the long term and helps protect customers from potential problems.
