FAQS about Solar photovoltaic panel performance test

What is a photovoltaic performance laboratory testing service?

Our photovoltaic performance laboratory testing services for solar panel products provides independent verification of warranty claims, endurance, output, and functionality in a variety of climate or conditions.

How do you test a photovoltaic system?

The power generation of a photovoltaic (PV) system may be documented by a capacity test [1, 2] that quantifies the power output of the system at set conditions, such as an irradiance of 1000 W/m2, an ambient temperature of 20°C, and a wind speed of 1 m/s. A longer test must be used to verify the system performance under a range of conditions.

Why do we need a performance guarantee for a large photovoltaic system?
