The UNEF Quality Certification is a certification developed by UNEF that endorses the technical capabilities of an installer company and good practices in the design and execution of its installations.
It is aimed at companies installing rooftop photovoltaic self-consumption systems in Spain that wish to stand out for their quality and safety processes, as well as for the training of their installers.
Any company in the sector can apply for the UNEF Quality Certification, whether or not it is a UNEF member.
The UNEF Quality Certification consists of three phases:
The first phase consists of a training process for all the company's self-consumption installers. Once this first phase has been successfully completed, the company's technical capabilities will be assessed through an inspection of the company and one or more photovoltaic installations.
Once Phases 1 and 2 have been successfully completed, the certificate will be issued.
The process is presented schematically in the original documentation.

For more information, please refer to the following documents, all of which are available in Spanish:
Once the certificate has been issued, it is valid for 3 years.
