Meet the requirements of punishing conditions in global markets where photovoltaic (PV) solutions are in high demand

Did You Know?

  • Large centralized solutions built using smaller blocks (aka, modularity) demonstrates the ability to allow greater design flexibility and improved redundancy. 
  • The U.S. Department of Energy announced that the U.S. solar industry reached its 2020 utility-scale solar cost target of US $0.06/kWh three years ahead of schedule.  

The demand for cleaner, smarter energy—in the form of solar energy—is greater than ever in countries across the globe, with the US, China, and India leading the way. The global PV market itself has grown every year for over a decade, giving manufacturers the chance to play a critical role in promoting sustainable energy production and reducing carbon emissions, while enjoy substantial sales.

As part of our own commitment to supporting safe and efficient renewable energy, CSA Group provides customized testing services that examine the reliability, performance, and quality of your products under conditions that accurately simulate solar energy service—helping them meet the unique requirements of the application and markets you wish to enter.

State-of-the-Art Testing Facilities
Our PV and environmental testing facilities enable us to offer exceptional testing of the highest accuracy and quality. These facilities feature:

  • Advanced technology A+/A+/A+ grade solar flashers to precisely reproduce high-intensity light under controlled temperatures
  • Expertise with all PV technologies: c-Si, thin film, PERC, and bifacial
  • Environmental chambers to evaluate performance in controlled temperature and humidity conditions
  • Light-soaking and UV chambers to simulate extended sunlight exposure
  • IEC testing capabilities to help ensure conformity with international safety and performance standards
  • An expansive outdoor testing area to evaluate your PV modules on fixed racks and both single-axis and dual-axis trackers

CSA EXP450: Our Own Testing Protocol for the PV Sector
With input from many PV sector leaders and stakeholders, CSA Group developed a definitive best practice document for all PV testing protocols: CSA EXP450 Photovoltaic (PV) Module Testing Protocol for Quality Assurance Programs. C450 serves as the basis for testing programs at our state-of-the-art labs in both the U.S. and China.
