Determining the long term cost impacts of deploying various wire management devices can be daunting. TECSI’s Wire Management Cost Estimation tool can assist system designers and asset managers in creating a more accurate O&M budget based upon the choice of deployed device.
This comprehensive article by principal engineer Samuel Truthseeker, dives into the world of wire management reliability and longevity by covering the risks associated with deploying cable ties, wire clips, and integrated wire management devices. In addition, he provides tools for developers and asset managers to critically evaluate manufacturer’s test data and provides guidance for creating more sophisticated and accurate O&M cost models.
Don’t let the complexity of ASCE 7-16 keep you from designing to the new standard. We’ve taken the complexity out of the process, making it easy and intuitive with our online calculator. Contact TECSI for a stamped version of the output from this residential system design tool.
TECSI Solar has developed API modules for both residential and commercial rooftop systems. These APIs take system design inputs and calculate all ASCE 7-16 engineering requirements. The output from our APIs can then used by design tools to report all relevant engineering parameters such as max spans and cantilevers for residential systems and ballast and anchor maps for commercial systems. Both modules include extensive standard and engineering optimization algorithms to ensure you get the most out of your products. Partner with TECSI to upgrade your current design tool to the latest requirements. Our APIs make the update process predictable, quick, and painless.
As pressures increase to reduce system costs and increase reliability, some product manufacturers are adding integrated wire management to their products to reduce installers’ costs and installation times. This trend has the potential to fundamentally change the way we think of PV system wiring. TECSI engineers go into depth on this topic in their poster presented at the 2018 Solar Power International technical symposium.
SoftPaw is an innovative wire management feature for PV modules. Since it comes integrated into the frame wall of the module, it’s always exactly what you need where you need it. With SoftPaw, you no longer need wire clips for PV module pigtails or home run cables. It’s easy to install and will hold fast for the life of the system without compromising the integrity or longevity of the wire. SoftPaw is the most extensively tested wire management device in the market. Its low cost, flexibility, and reliability make it the ultimate wire management device for the solar industry.
The SolarCleat is an innovative wire management feature for ground mounts, carports and trackers. Since the SolarCleat can be cut into the C channel when it is being roll formed, it has virtually zero cost after initial tooling investment. Don’t scramble to order the right clips or track them down at the job site. Ask your product manufacturer for SolarCleat to streamline the installation process, saving time and money.
In 2016, Samuel from TECSI presented at the SEIA PV Technical Training at Solar Power International. His 1 hour presentation takes a deep dive into the history of PV fire testing and includes a primer on evaluating the performance of a fire test. Samuel also covers new proposals which he spear headed, that if passed by the standards technical panels would significantly reduce certification costs for typical racking technologies.
In 2016, Samuel from TECSI presented at the SPI codes and standards summit. His 20 minute presentation offers a perspective of emerging PV module technologies and how standards will need to respond to these changes in the future. His presentation also included a summary of proposals that if approved would allow for exemptions for fire testing for certain types of racking systems.
In early 2016, Samuel spear headed activities with SEIA and the UL1703 Standards Technical Panel, to provide evidence that placing PV systems over noncombustible roof coverings would not degrade the fire rating of the roof. Samuel provided the test plan, reports, and many of the underlying theories and language behind the UL 1703 exception for non-combustible roofs. The following test report provides background and conclusions from this testing.
