While solar PV systems may appear simple from a distance, keeping them up and running takes more than just mounting panels and walking away.

As part of Electrical Business Magazine’s Alternative Energies Theme Week—brought to you in partnership with test & measurement leader Fluke—we explore the Top 3 problem areas in solar PV installations: ground faults, PV modules, and inverters.

Host Anthony Capkun sits down with Will White, Fluke’s senior applications specialist and a long-time solar pro, to dig into common causes, telltale signs, and diagnostic approaches for identifying and resolving performance issues in the field.

From wire management best practices and insulation resistance testing to IV curve tracing, aerial thermography, and the soon-to-launch GFL 1500 ground fault locator, White shares practical tips for installers and maintenance techs alike. He also dives into inverter diagnostics, power quality concerns, and data communication issues that often crop up in large-scale systems.

Whether you’re building new or troubleshooting existing PV systems, this conversation provides expert advice for keeping your solar arrays safe, efficient, and producing power.
