Solar modules, inverters and batteries are not consumer products, and their service life can be long as several years or decades, but their quality and long-term reliability should not be judged only by appearance. In order to ensure the quality and long-term reliability of solar products, users can take the following measures:

(1) The most basic is to require the manufacturer to provide authoritative test and certification reports to ensure that the technical performance of the products submitted for inspection meets the technical standards and passes the third-party test. All range of Raytech solar modules have passed the TUV Testing and got certifications for TUV and CE. Raytech will guarantee the products with 12-year product warranty and 30-year performance warranty;

Raytech TUV Certification

(2) As PV modules and inverters are not short-term consumer goods, they need to be checked again after one year of operation. The failure rate must be within the scope of the contract.

(3) In addition to the quality of products and parts, the engineering design and construction of photovoltaic project is also very important. In order to ensure the quality of the project, the project developer must also entrust a qualified and experienced third party to review and supervise the whole process of engineering design, construction and installation, project inspection, etc.
