According to Article 690, what should be the overall focus of a PV system installation?

The overall focus of a photovoltaic (PV) system installation, as outlined in Article 690 of the National Electrical Code (NEC), is centered on safety and reliable performance. This is crucial because the installation of PV systems involves high voltages and currents that can pose serious hazards if not properly managed. Ensuring safety involves adhering to specific guidelines and standards that protect not only the installers but also the end-users and the public.

Reliable performance is equally important, as it ensures that the PV system operates effectively over its intended lifespan. This encompasses not just the initial installation but also ongoing maintenance and the ability to withstand environmental factors. By focusing on safety and reliability, installers help guarantee that the system functions correctly and minimizes risks such as electrical fires, shock hazards, and system failures.

While efficiency, cost reduction, and the use of the latest technology may be worthwhile considerations in the installation process, they should not overshadow the paramount objective of ensuring safe and dependable operation of PV systems. Compliance with local codes is also significant, but it is primarily a aspect of maintaining safety and reliability, rather than an end goal in itself.
