Why Our Testing Matters

Long-term field data does not exist for solar power plants.

Over 80% of the world’s installed solar capacity has been operating for less than five years. PVEL’s expert, independent lab and field testing creates the data that developers need to procure reliable equipment and forecast system performance. Our testing suite is designed to facilitate project financing.

Hear from our clients and partners

“

PVEL has provided consistent, reliable support to Origis Energy over the years through their Product Qualification Program and Batch Testing to ensure a high-level of confidence in the quality and reliability of our chosen solar modules. Their services were instrumental for technical diligence for our financing partners across multiple utility scale solar projects. We look forward to continuing our relationship with PVEL.

“

As a downstream partner to PVEL, I know their product qualification programs and reports are tremendously valuable. Their team works tirelessly and with integrity to illuminate the risk in PV module procurement for a variety of applications, whether it be for a modest 4kW residential system or a 500MW utility-scale project.
