As buildings are updated with high-efficiency LED light sources, energy codes generally require that the lighting control systems also be updated to satisfy new, more efficient performance requirements.
The new Copper-clad aluminum building wire (Cu-Clad), however, displays improved physical characteristics due to the alloying of its core, designed to improve its application to building wire.
The purpose of this article is to inform, educate, and offer guidance in properly identifying when an AC disconnect is required for a residential or small commercial PV installation.
In continuing the task of locating and inspecting homes wired with Cu-Clad BCBW, D’Agostino solicited the assistance of Mr. John Yeamans, a long-time resident of Farmingville, NY, and a local real-estate agent serving all of Long Island.
Photons (solar energy from sunlight) hit a PV module and electrons (electrical energy) come out. The amount of electricity (volts and amps) a PV module will produce is proportional to the amount of sunlight shining on the module (more is better),
Energy efficiency involves reducing energy consumption, optimizing energy costs, and improving installation reliability. To achieve a high level of energy efficiency, there are at least six solutions you can apply.
This article attempts to lay the foundation for properly planning for inspection of a large-scale PV project, developing an inspection team, and communicating with all of the players.
Large-scale PV plants have become commonplace in the desert southwest with plants routinely exceeding 100 MW in size. How does that impact the local AHJ and why is Article 691 for large-scale PV electric supply stations even in the NEC?
Photovoltaic power systems are proliferating and are going to be a major player in our nation’s energy mix. The inspector community must be able and willing to inspect these systems as the last line of defense in ensuring the safety of the public.
To have Cu-Clad BCBW in service within these two different climates for five decades can provide real-world insight into its performance.
