Extended Bankability for PV module(s)

TÜV Rheinland’s service for PV modules to ensure their reliable operation in the field

Bankability plays a pivotal role in solar investment, offering investors confidence in the quality, longevity, and reliability of the solar module, as well as the credibility of its manufacturer. Independent Engineering (IE) firms like TÜV Rheinland provide bankability reports, which are instrumental in helping downstream buyers determine if they are investing in suitable products for their specific project needs.

These comprehensive reports include various evaluations such as financials, technology roadmaps, certifications, product design, performance analysis, installation guides, in-process quality controls, internal lab-testing, extended reliability test reports, incoming and outgoing inspections, step-by-step production audits, after-sales service, warranty, past installation locations, and site visits.

Who are we serving and what we are providing?

TÜV Rheinland’s services are designed for manufacturers, planners, system designers, installers, testing institutes, and building authorities.

TÜV Rheinland has established criteria for PV modules, as detailed in the 2 PfG 2940/06.23 standard. These criteria aim to ensure the reliable operation of the modules in the field and provide accurate data for system designers to make trustworthy energy yield predictions. The standard includes eight test sequences, each addressing specific failure modes commonly observed during the operation of PV modules in the field. They include testing a product sample and conducting regular production monitoring, which encompasses factory audits, product testing, and certification. The data from these tests not only allow system designers to make reliable energy yield predictions but also enhance consumer confidence through product certification.

Independent Testing for Your Global Market

While financial institutions offer bankability ranking reports, they acknowledge the limitations of their analyses in providing clarity on extended reliability issues for specific model types. Thus, independent testing, like TÜV Rheinland’s “Extended Bankability” service, becomes a critical step for manufacturers to demonstrate the durability and reliability of their technology over time.

In markets with rigorous bankability requirements, such as Europe or the US, independent testing doesn’t just help manufacturers gain recognition and respond to project RFPs swiftly, it also opens doors to new buyers and markets. This service presents a golden opportunity for new manufacturers to import their products into countries where policy decisions have limited supply, thereby opening up a significant market.
