Abstract: . . .  or Sharp modules, the maximum difference in P mp was less than 3.5%. CONCLUSIONS The effort to replicate outdoor test methods and data analysis procedures used at Sandia has been very successful, achieving high levels of both repeatability and agreement between both labs. Additional periodic module intercomparisons using the Sandia procedure are planned in order to maintain agreement between the labs. This work allows ASU-PTL to provide commercial testing services to the industry based on the Sandia method. REFERENCES [1] D. L. King, W. E. Boyson, J. A.
