ASTM Develops Proposed Photovoltaic System Standard

Post Time:Dec 01,2011Classify:Industry NewsView:213

 

A proposed new ASTM International standard will simplify the process of photovoltaic system acceptance and help reduce the cost associated with negotiating a PV system purchase, according to a November 29 release from ASTM International. 

 

According to Adrianne Kimber, director, performance and prediction, First Solar Inc. in Tempe, Ariz., and an E44 member, once ASTM WK22009 has been approved it will serve two primary functions, the first being PV system acceptance.

 

“When a system developer sells a PV system, they aggregate many different components into a custom-built system,” Kimber said in the release. “When the construction is complete, the system owner needs some method of judging whether this complex, custom-built system will do what the developer said it would do.” ASTM WK22009 will outline a test method that can be used to determine a PV system’s power production capacity compared to agreed-upon specifications.

 

In addition, the test contained in the proposed standard will serve as a useful means of tracking PV system performance over time.

 

“This test can be run periodically throughout the course of a PV system’s life to accurately track the long-term change in the performance of the system,” Kimber said in the release.
