What qualifications do photovoltaic power station operation and maintenance companies need?

Units engaged in the construction of photovoltaic power generation projects shall have the Permit for Undertaking (Repairing and Testing) Power Facilities. Units and individuals that have not obtained the license for undertaking (repairing) the inspection of power facilities shall not engage in the business of undertaking (repairing) the inspection of power facilities. The license grade is divided into Grade I, Grade II, Grade III, Grade IV and Grade V, and the grade is divided according to the construction voltage grade.

Those who have obtained the first-class license can engage in the installation, maintenance or test activities of all voltage-grade power facilities.

Those who have obtained the second-class license may engage in the installation, maintenance or test activities of power facilities with voltage levels below 220 kV.

Those who have obtained the Grade III license can engage in the installation, maintenance or test activities of power facilities with voltage levels below 1 10 kV.

Personnel who have obtained Grade IV license can engage in the installation, maintenance or test of power facilities with voltage below 35 kV.

Those who have obtained the Grade V license can engage in the installation, maintenance or test activities of power facilities with voltage levels below 10 kV.

According to the Regulations on the Administration of Construction Engineering Survey and Design Qualification (DecreeNo. People's Republic of China (PRC) Ministry of Construction 160):

"the State Council construction administrative department is responsible for the unified supervision and management of the national construction engineering survey and engineering design qualification. The State Council railway, transportation, water conservancy, information industry, civil aviation and other relevant departments cooperate with the State Council construction authorities to implement construction engineering survey and engineering design qualification management of corresponding industries. "

Therefore, the design qualification is relatively unified. Photovoltaic engineering's design qualification is "power industry (new energy power generation)". Of course, it is acceptable if it is the power design qualification at the next higher level, because the qualification is backward compatible. If it is a distributed photovoltaic building project, which involves the change of building structure and function, it still needs architectural design qualification.
