Tucson, AZ (PRWEB) October 18, 2011
Schletter Inc., a U.S. manufacturer of solar photovoltaic (PV) mounting systems, announces drastically reduced ballast requirements based on extensive wind tunnel testing on the company’s Windsafe solar mounting system. Testing was performed by renowned independent laboratory Ruscheweyh Consult GmbH, complying with U.S. and European standards.
Instead of using the common aerodynamic wind tunnel approach, Schletter conducted a comprehensive atmospheric boundary layer wind tunnel study, providing a real-life example. The analysis included wind forces on the structure based on wind speed, importance categories, exposure, and system characteristics, which when combined determines the structural load placed on the building form PV systems. In addition, fully configured solar PV systems with various row configurations, module orientation, and tilt angles ranging from 5 to 35 degrees, and the presence of parapet walls were included in the test parameters.
“Though Schletter has data from previous wind tunnel tests, the latest results expand on this historical data and include a wider variety of possible system layouts,” says Wolfgang Fritz, Vice President of Engineering for Schletter Inc. Mr. Fritz goes on to say that “We chose to use a well-known third party in order to provide our customers with a higher level of assurance and quality. In the end, we can expand on our solar mounting configurations making our systems more versatile than ever before.”
Resulting data produced has created new system options for the company, expanding product line versatility, and offering price cutting configurations in present designs. At the forefront of test results are the combination of reduced material and low ballast loads in multiple mounting system configurations including the popular arrangement of two modules in portrait.
