    Solutions, results

    Our extensive experience in the photovoltaics sector and profound knowledge of international standards made TÜV Rheinland the best choice for KfW IPEX-Bank.

    Throughout the entire project, we offered technical advice to enhance the quality and safety of the PV power plant. In addition, we provided technical due diligence to assess the project feasibility and to ensure that financial investments were based on verified data. In order to grant certification, our team of lender’s engineers had to conduct several inspection and assessment services including a review of plant design, suitability of the components, power measurements both on-site and in the laboratory, a review of energy yield calculations, and the taking of infrared pictures of the on-site PV modules.

    To guarantee compliance with all relevant standards and regulations, our experts performed a final plant acceptance inspection placing a special emphasis on safety and ultimately awarded the Italian PV plant in Viterbo a Quality Certification.
