Provide assurance of the quality, safety and performance of PV plants from the onset
Photovoltaic (PV) power plant operators and investors may face operational failure risks such as planning errors and installation defects. It is important to prevent these risks at the early phases of a solar project. During the planning stage, operators and investors have to ensure that the PV plant connects with the grid and adheres to safety standards.
For investors to be guaranteed assurance of their investment, a PV system should achieve its expected lifetime and deliver performance according to design specifications. In the case of an insured event, investors need to have the appropriate technical documentation to avoid unnecessary costs and delays.
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.
TÜV SÜD provides Certification Level I for PV plants after first grid connection and Certification Level II for PV plants in production.
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).
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.
