Let’s take a look at some of the more significant changes impacting photovoltaic (PV) installations once the 2020 National Electrical Code (NEC) is validated by the NFPA Standards Council.

This feedback demonstrates that there are plenty of misconceptions among the electrical designers, contractors, and regulators on certain provisions of the legally adopted National Building Code of Canada (NBC) and the CE Code on electrical equipment.

Are there any Certified (Listed) products available to meet new PV rapid shutdown requirements inside the array boundary?

Take this quiz on solar photovoltaic requirements in the 2017 National Electrical Code to test your code knowledge; have your codebook ready!

I am having trouble interpreting Section 705.12(D)(3) [NEC 2011] and the exception to 705.32. Specifically, I am having issues with the exception.

These voltage drop formulas are based on conductor DC resistance values and are viewed as generally acceptable for voltage drop calculations.

New and exciting improvements in the photovoltaic (PV) modules and PV systems are occurring each day.

By now, we’ve all had the opportunity to experience a PV wiring system, whether installing, inspecting, or encountering alongside other electrical work.
