Ensure the quality, safety and performance of your PV plant from the onset.

What is solar photovoltaic (PV) Plant certification?

Solar photovoltaic (PV) plant certification is a process of assessing and verifying a solar PV power plant's performance, quality, and safety. The solar PV plant certification is typically carried out by independent third-party certification bodies, such as TÜV SÜD, to assure investors, lenders, and other stakeholders that the solar PV plant meets specific standards and requirements.

Solar PV certification involves testing and certification procedures to ensure the quality, safety, and performance of the entire plant and 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?

Solar PV plant certification benefits project developers, investors, and other stakeholders. It helps ensure that the solar PV plant is built and operated to high quality and safety standards and can deliver the expected energy output and financial returns. It also assures lenders that the project is a good investment and can reduce the project's financing costs.

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

The PV certification process involves a detailed evaluation of the solar PV plant's design, construction, and operation, as well as the equipment used, such as solar modules, inverters, and mounting systems. The certification body will verify that the solar PV plant complies with relevant regulations, standards, and guidelines and assess its performance and reliability under various operating conditions.

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. Through the solar photovoltaic certification process, we test component functionality, evaluate PV plant quality and verify the fulfilment of technical and safety standards.

Our PHOTOVOLTAIC 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 relevant standards. 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.

TÜV SÜD’s photovoltaic certification ensures assessing and verifying a solar PV power plant's performance, quality, and safety. It assures investors, lenders, and other stakeholders that the project meets specific standards and requirements.


Solar photovoltaic (PV) certification offers several benefits for project developers, investors, and other stakeholders in the solar industry. Here are some of the key benefits:

  • Quality assurance: Solar photovoltaic certification provides independent third-party verification of the quality and safety of the solar PV system. Certification ensures that the solar PV plant meets specific standards and guidelines and is built and operated to high quality and safety standards.
  • Improved performance: Solar photovoltaic certification assesses the performance of the solar PV plant under various operating conditions, which helps to identify areas for improvement and optimisation. This can lead to increased energy output and financial returns for the project.
  • Lower risk: Solar photovoltaic certification can help to reduce the risks associated with investing in a solar PV project. It provides assurance to investors, lenders, and other stakeholders that the project is a good investment and can reduce financing costs and insurance premiums.
  • Compliance: Solar photovoltaic certification ensures that the solar PV plant complies with relevant regulations, standards, and guidelines. This helps avoid legal and regulatory issues and ensures that the project is eligible for incentives and subsidies.


TÜV SÜD is a leading provider of PV solar certification services, and choosing TÜV SÜD for your PV solar certification needs can provide several benefits. One key advantage is their comprehensive site assessment for solar PV, which includes a detailed analysis of your solar project's design and location to ensure compliance with relevant standards and regulations. This can help to identify potential issues early on, reduce project risk, and improve overall system performance. Additionally, TÜV SÜD has a strong reputation for quality and reliability, and their certifications are recognised worldwide, which can help to increase your project's credibility and marketability.




  • What is PV certificate?

    A PV certificate is a document issued by a third-party certification body that verifies the performance and safety of a photovoltaic (PV) system or component, such as a solar panel or inverter. These certificates may be based on industry standards, such as the IEC 61215 standard for solar panels.

    The certification process typically involves testing and evaluating the product to ensure compliance with these standards, as well as regular factory inspections and ongoing quality control checks to maintain the certification. PV certificates are important for demonstrating the quality and reliability of PV products to customers, investors, and regulatory bodies and may be required for eligibility for government incentives or utility interconnection programs.

  • What is a PV inspection?

    A PV inspection is an evaluation of a photovoltaic (PV) system, typically conducted by a qualified technician or inspector, to assess the system's performance, safety, and compliance with applicable standards and regulations. PV inspections may be performed for various reasons, such as identifying and diagnosing problems with the system, ensuring that the system is operating at optimal efficiency, or verifying compliance with local codes and regulations.
