Validation

Technical validation before and during development, construction and operation.

Quality Assessment

Quality assessment of modules, inverters, batteries, and components in the factory, laboratory and field.

Independent reports

Independent reports that facilitate decision-making with IPPSs, banks, investors and EPC contractors.

We offer specialized services to ensure that photovoltaic systems reliably generate energy for more than 25 years. We evaluate modules, inverters, and mounting structures through inspections, tests, and audits that reduce technical risks and ensure long-term performance.

Our BESS services ensure the safe and stable operation of energy storage systems through evaluations of cells, modules, and complete systems. We identify critical risks such as thermal runaway and verify that the hardware meets the highest quality and safety standards.

Our Solutions

Comprehensive technical solutions for every phase of your photovoltaic project

Many of the defects that affect PV and BESS installations can be detected and prevented at the source. At Kiwa PI Berlin, we ensure quality from the outset through audits and production monitoring, detecting defects before shipment. We ensure consistent processes and reduce long-term reliability risks.

We independently validate the reliability and durability of components through advanced testing in our independent, ISO 17025-accredited laboratories. We confirm that materials and designs do not compromise future performance. Kiwa PI Berlin has laboratories in Europe (Berlin), Asia (Shanghai), and the U.S. (PVEL Labs, California).

We perform on-site quality control during acceptance, installation, and commissioning. We use tools such as thermal imaging and electroluminescence to verify the proper performance and safety of the equipment.

We support key industry players throughout the entire value chain—from development, design, and contract negotiation to commissioning, operation, and on-site troubleshooting. We identify and quantify technical risks to support investment and operational decisions.

We support the initial phase of the project with technical specifications, system optimization, and production studies. We define requirements that ensure efficiency and performance in solar PV and BESS.

We are familiar with and actively involved in the development of the most rigorous standards in ESG and traceability. We protect the credibility of our clients’ assets by designing and conducting specific audits at key project milestones. We audit supply chains to verify the origin of materials and compliance with ESG regulations. We ensure traceability and responsible practices in the manufacturing of components.

Securing Investment and Mitigating Financial Risk in PV & BESS Projects

Technical Due Diligence (TDD) and risk analysis prior to financial close, as well as post-COD certifications to identify, quantify and manage project risks.

Ensure the quality of key equipment (modules, inverters, mounting structures and batteries) prior to installation.

Factory audits, production oversight, testing at an ISO 17025-accredited laboratory and pre-shipment inspections to ensure the reliability of all components.

The need for specialized technical expertise in drafting contracts and license terms

Drafting of technical specifications and bidding documents, as well as support in negotiating EPC and O&M contracts, and precise definition of the system’s technical and performance requirements.

Oversee the construction, commissioning, and quality assurance of the project on site:

Supervision of construction and commissioning through periodic visits or a continuous on-site presence, in addition to conducting quality checks on equipment upon its arrival.

Identify the cause of unexpected failures or defects in installed components:

Root cause analysis combining remote data evaluation, on-site inspection and specific component testing to determine the source of the failure.
