The latest standards for photovoltaic bracket purlins

What is solar panel support with Z profiles and purlins brackets?

Solar power systems use the sun’s rays as a high-temperature energy sources to produce electricity in a thermodynamic cycle. Thereby we have to introduce some solar panel support with Z profiles and purlins brackets, which are hot galvanized steel material for use in long time with better surface and the best cost during the system construction.

Why are international standards important in the photovoltaic industry?

ABSTRACT: International standards play an important role in the Photovoltaic industry. Since PV is such a global industry it is critical that PV products be measured and qualified the same way everywhere in the world. IEC TC82 has developed and published a number of module and component measurement and qualification standards.

What size bridging is required for a purlin roof?

Alternative hole sizes, shapes and centres are possible, subject to enquiry. Stramit recommends that bridging be installed such that the maximum unbraced length is 20 x D (where D is the purlin web height), or 4000mm whichever is the least. In addition to enhancing purlin performance this requirement assists with the erection of roof sheeting.

Why do large purlins require large bridging systems?

Large purlins require large bridging systems due to the larger spans and heavier loads encountered. These bridging components are conventional in nature but on a much larger scale. Generally the bridging channel is a C150 section firmly bolted to end plates to suit the particular purlin concerned.

What is the bolt strength of a roof purlin?

The bolt strength grade (4.6 or 8.8) should be specified by the design engineer to conform with the Stramit® Purlins, Girts & Bridging – Product Technical Manual. Loads to be suspended from roof purlins must be accounted for in design. No allowance is included in the capacity tables.

What rack configurations are used in photovoltaic plants?

The most used rack configurations in photovoltaic plants are the 2 V × 12 configuration (2 vertically modules in each row and 12 modules per row) and the 3 V × 8 configuration (3 vertically consecutive modules in each row and 8 modules per row). Codes and standards have been used for the structural analysis of these rack configurations.
