Post-form call-out, 6 words max recommended

The long-term effort to harmonize the PV module safety and construction standards is coming to a close. Harmonization involves evaluating requirements in the base standard for different geographical markets to identify common elements and specific national or regional differences. The combination of updates in IEC 61730, published Aug 2016, is the basis for harmonization with UL 1703 and will result in UL 61730-1 and UL 61730-2.

While the publication of the harmonized standard does not immediately replace UL 1703, it is important to know now how changes will impact your current PV module or system design. Whether you’re a manufacturer, integrator, installer, inspector, developer or financier of PV systems, you’ll benefit from the knowledge shared in this webinar from the experts that participated in writing the standard.
