Calculating Bifacial PV Circuit Max Current in the 2026 NEC
Bifacial PV modules introduce new complexities into determining maximum circuit current for circuits as the National Electrical Code (NEC) doesn’t provide a clear method specific to bifacial modules and manufacturer documentation provides numerous short-circuit current values. This article examines what the 2026 NEC says, why it says it, and dives into relevant product safety standards Read more

The 2026 NEC® and the Future of Electrical Systems: EVs and EV Supply Equipment
Electric vehicles (EVs) now account for over 20% of annual global automobile sales, a number that is expected to continue growing. EV’s store a lot of energy — it takes a lot to move thousands of pounds hundreds of miles. This comes with challenges for existing electrical infrastructure since EVs can behave as a significant Read more

The 2026 NEC® and the Future of Electrical Systems: Controlling Power and Managing Energy using PCS and EMS
Electrical system design has been rooted in a fundamental principle for a long time: calculate the theoretical, worst-case-scenario load, then build a system robust enough to handle it. Traditional load calculations are based on estimations, assumptions, nameplate ratings, and demand factors. But in an era of distributed generation, energy storage, and heavy but controllable loads Read more
