MaxSolar and Sinovoltaics partner to deliver a Million 100% defect-free solar modules per year for its utility projects

Traunstein, Germany & Lausanne, Switzerland – February 19, 2025 – As the solar industry faces concerns over solar module defects, MaxSolar, a leading German solar developer and independent power producer (IPP), has taken a decisive step to eliminate equipment quality and project downtime risks. The company has partnered exclusively with Sinovoltaics, a global leader in photovoltaic (PV) quality assurance, to ensure 100% defect-free solar modules across its utility solar projects.

As a prominent IPP in Germany/Europe, MaxSolar procures its PV modules from suppliers worldwide. The agreement calls for Sinovoltaics to employ its proprietary Sinovoltaics EL Mass Analysis (SELMA) technology to inspect over one million solar modules per year at PV manufacturing facilities in Europe, India, and Asia.

Unlike traditional batch sampling methods that examine only 1% to 3% of a module order, SELMA’s AI-driven defect analysis software will inspect 100% of MaxSolar’s procured modules at the factory. SELMA identifies microcracks, soldering issues, and other hidden defects. When issues are found, Sinovoltaics’ onsite inspectors ensure that every defective module is corrected or replaced, then retested before shipping.

“With our expansive utility project pipeline, quality assurance is required to ensure long-term performance and revenue,” said Christoph Strasser, CEO of MaxSolar. “Traditional sampling methods leave too much to chance — defective modules can slip through undetected, compromising solar production and profitability of entire projects. By partnering with Sinovoltaics and using their SELMA inspection, we can be confident that every module MaxSolar procures meets the highest performance and reliability standards.”

Sinovoltaics’ SELMA technology has tested more than 15 million solar modules globally since 2020. In the first half of 2024 alone, across various projects using Tier 1 manufacturers, SELMA revealed that over 12.5 MW of PV modules had non-conforming cell-inherent defects, such as microcracks and soldering anomalies. Thus, SELMA saved project developers and investors from replacing over $2 million in defective modules.

“We are excited to be supporting MaxSolar’s commitment to reducing solar project risks and ensuring the PV module quality and reliability,” said Arthur Claire, Sinovoltaics’ Director of Technology. “By utilizing SELMA’s 100% inspection and defect-prevention approach, MaxSolar is setting a new benchmark for utility developers and solar asset owners that want to reduce long-term financial and operational risks for their solar projects.”
