Whether you''re navigating the complexities of load side and supply side connections or seeking to optimize your installations for peak performance, CNG Solar Engineering offers the
Compare supply-side vs load-side solar interconnections. Understand the 120% rule, NEC requirements, and how to choose the right method for your project.
It differentiates between load side connections —those made downstream of the service disconnect—and supply side connections, which interface directly with the utility''s supply network.
Adding a solar source does not increase the load or current that those conductors will see. The solar output goes into the system or goes into the panel. As long as the solar output does
A deep dive into NEC 705.12, explaining the rules for determining a code-compliant point of connection (POC) for a PV system on the load side of the service.
Our dual glass modules use the same internal circuit connection as a traditional glass-backsheet module but feature heat-strengthened glass on both sides. We produce the back glass
When you think about solar panel efficiency, do you ever consider what holds those shiny photovoltaic glass panels in place? The photovoltaic glass and bracket connection acts like the skeleton of your
Understand solar interconnection types—supply-side vs load-side—and learn how to design NEC-compliant, inspection-ready PV systems.
Interconnecting a Solar PV system is more intricate than it might initially appear, given the diverse service configurations in play. This article aims to provide clarity on the subject.
That said, the supply-side interconnection must include another service in parallel to the existing one with an additional OCPD and disconnect. The equipment and conductors must be rated to
