The product warranty
Solar panel manufacturers have done a lot of development to ensure their products have a long service life. Therefore, they also can provide long-term warranties for their products. Suntech, TrinaSolar and Risen Energy offer a 12-year warranty for their PV panels. The linear productivity warranty is 25 years, which means 84.8% of the PV panel efficiency after 25 years will be remained.
We offer a 2-year warranty for our installation works and a 5-year warranty for the fastening materials. The service life of metal fasteners is over 25 years. Inverters have a service life of approximately 20 years and the warranty period for the inverter from the manufacturer.
