Solar Photovoltaic (PV) Plant Certification

What is solar photovoltaic (PV) Plant certification?

PV plant certification involves testing and certification procedures to ensure the quality, safety and performance of the plant as a whole as well as its components. It begins with a visual inspection to establish that the plant is built according to its documentation, followed by a review of PV component quality and a performance ratio analysis at the commissioning or operation phase.

Why is PV plant certification important?

Your PV plant requires certification and quality assurance at the system level to achieve bankability and differentiation. PV plant certification indicates that there are no installation faults, offers assurance of investment through verification of energy yield assessments and provides your business partners with a reliable basis for future decision making.

TÜV SÜD helps to verify that your solar PV plant complies with safety and quality standards and regulations.

TÜV SÜD supports crucial decision-making in the planning phase through shadowing measurement, energy yield calculation and on-site inspections. We test component functionality, evaluate PV plant quality and verify the fulfilment of technical and safety standards.

Our PV plant certification services include:

• Final acceptance test
  

  Our experts verify the completeness of handover documentation in line with system documentation requirements (IEC 62446 Clause 4) and initial or periodic plant verification of an installed system (IEC 62446 Clause 5).

• Structural assessment
  

  We assess the solar mounting structure according to the Eurocodes (European design standards) as well as EN 1090-2 or EN 1090-3. Furthermore, we perform a visual inspection of mounting structures and their foundation.

• Remote monitoring data analysis
  

  We evaluate and determine the reliable functioning and maximum yield of a PV plant. Our data evaluation ensures high performance, low downtime and fault detection in the plant, including early warning notifications of potential faults. This solution offers secure data evaluation throughout the plant’s lifetime.

• Performance acceptance test / Performance ratio assessment test
  

  TÜV SÜD analyses the performance ratio parameter according to IEC 61724 as well as the yield production parameter by comparing theoretical and real output power production.
