Considering the complexity of the PV systems and the environment in which they operate, electrical inspections of PV systems is no easy task for the AHJ.

A new safety standard in Canada for photovoltaic combiners has been developed known as CSA Standard C22.2 No 290 Photovoltaic Combiners. The 2015 Canadian Electrical Code Part I (CE Code) defines a photovoltaic combiner as...

With the rapidly growing commercial use of 3D printers to make parts, manufacturers still unfamiliar with this technology need to know its advantages and drawbacks compared to injection molding.

I have spoken with building department officials who have seen an increase of five to ten times in solar permit applications over the last few years. It is a tough task for them to keep up with the volume with no increase in budget or resources.

Photovoltaic power systems, like other electrical power systems, require overcurrent protection for conductors, bus bars, and some equipment.

A few years back while at an IAEI sanctioned event, I remember talking with a senior plan-checker about large-scale PV systems versus residential PV systems. I attempted to describe the major differences, but was met with skepticism and a general statement was made that large-scale PV systems “are no different than residential PV systems.”
