Who Really Holds the Risk When Solar Quality Is Weak? On a utility-scale solar project, the contracts spell out who is responsible when work turns out to be bad. Julie Stiglish, a master electrician and quality consultant for utility-scale solar, says the people who actually carry that risk are usually… Continue reading “Who Really Holds the Risk When Solar Quality Is Weak?”
Two Habits Every New Solar Installer Should Build From Day One Solar installation is physical, technical work with real consequences when things go wrong. The Bureau of Labor Statistics projects employment of solar PV installers to grow 37 percent from 2025 to 2035, much faster than the average for all occupations.… Continue reading “Two Habits Every New Solar Installer Should Build From Day One”
Three Reasons Solar Breaks the 1-10-100 Quality Rule The 1-10-100 rule is a quality management concept that’s been around for a long time, and it’s a shorthand for what a defect costs at each stage. Preventing a problem costs one unit. Fixing it before it leaves your hands… Continue reading “Three Reasons Solar Breaks the 1-10-100 Quality Rule”
Why Neutral and Ground Bond Only Once Neutral and ground get bonded together at the main service panel, and nowhere else. Leave the bonding screw in at a subpanel and everything still seems to work. The lights come on and the appliances run. So why does the… Continue reading “Why Neutral and Ground Bond Only Once”
What a Bad Connector Costs: Day One vs. Year Three On a utility-scale solar project, a partially mated connector takes a few seconds to fix on install day. The installer doesn’t hear the click, so they push it until it locks or reseat it. Three years later, that same connector… Continue reading “What a Bad Connector Costs: Day One vs. Year Three”
An Accelerated Path to Drone Pilot Certification We just launched an FAA Part 107 Prep Course to help you get your drone pilot certification.

What Is a Ground Fault in a Solar System and Why Does It Matter? Ground faults are one of the more serious safety hazards in a PV installation. Understanding what causes them and what can go wrong is essential knowledge for anyone working on solar arrays. Janet Hughes has reviewed thousands of solar installations… Continue reading “What Is a Ground Fault in a Solar System and Why Does It Matter?”
Why Battery Storage Quality Fails Differently Than Solar | New BESS Course Quality teams that cut their teeth on utility-scale PV are now being handed battery storage scope too. The inspection habits that work on tracker rows don’t carry over cleanly, because the defects that cost the most on a battery project… Continue reading “Why Battery Storage Quality Fails Differently Than Solar | New BESS Course”
What Fails First in a Solar System? Sean White on Equipment Lifespan When you’re doing O&M on a solar system, sooner or later something’s going to fail – the question is what. Is it more likely to be the PV module, the racking, the electronics like inverters, or something like a combiner… Continue reading “What Fails First in a Solar System? Sean White on Equipment Lifespan”
Why Wire Management Is Still the Most Common Deficiency in Solar Installations The solar industry has grown fast, and that growth comes with a tradeoff. Contractors are under pressure to hire quickly and get people productive on the job site before they’ve had all the training they need. The result shows up… Continue reading “Why Wire Management Is Still the Most Common Deficiency in Solar Installations”
A Quality Defect Today Is a Safety Hazard Tomorrow on a Solar Site A lot of sites treat quality and safety like two separate departments, two different clipboards, two different inspectors walking the same row looking for different things. HeatSpring instructor Julie Stiglish thinks that split is part of the problem. In this… Continue reading “A Quality Defect Today Is a Safety Hazard Tomorrow on a Solar Site”
What Solar Manufacturing Can Teach the Job Site About Quality Most people who move into quality management learn it on the construction side, catching problems after they’re already built. HeatSpring instructor Julie Stiglish learned it from the other direction first. Before she was walking utility-scale sites as a quality leader,… Continue reading “What Solar Manufacturing Can Teach the Job Site About Quality”
Going From Electrician to Quality Leader: Julie Stiglish’s Path Into QA/QC Julie Stiglish’s path into quality and safety leadership didn’t start in a classroom or a compliance office. It started in the heat of a Las Vegas summer, wiring up casinos as a journeyman electrician, learning what it actually feels like… Continue reading “Going From Electrician to Quality Leader: Julie Stiglish’s Path Into QA/QC”
12 Moments When Utility-Scale Solar Quality Gets Decided Every utility-scale solar project is full of moments where a defect is cheap to catch and later moments where the same defect can cost ten times as much to fix. It turns out that many quality problems on a solar… Continue reading “12 Moments When Utility-Scale Solar Quality Gets Decided”
STC, NOCT, and NMOT: Sean White Decodes Test Conditions Used on the PV Module Datasheet Every PV module datasheet lists numbers like open-circuit voltage (VOC), max power voltage (VMP), and short-circuit current (ISC), but a module rarely actually operates at any of them. Differences in temperature and sunlight cause voltage and current to skew one… Continue reading “STC, NOCT, and NMOT: Sean White Decodes Test Conditions Used on the PV Module Datasheet”
New Course: Utility-Scale Solar QA/QC Fundamentals Julie Stiglish opens her new course with a story straight out of her own field experience: somewhere on a utility-scale site right now, a two-dollar defect is being installed. Nobody’s doing it on purpose. The crew is good, the weather’s… Continue reading “New Course: Utility-Scale Solar QA/QC Fundamentals”
What the O&M Agreement Covers and Why It’s Tied to Your Financial Model Solar assets need decades of upkeep, and that responsibility needs to be spelled out in the O&M agreement. Skipped infrared testing and visual inspections, excessive panel soiling, or an inverter failure without a response plan in place are just a… Continue reading “What the O&M Agreement Covers and Why It’s Tied to Your Financial Model”

New Free Course: 10 Utility-Scale Solar Defects Hiding in Plain Sight Every defect in utility-scale solar construction is cheap exactly once – at the moment it’s installed. After that, the price goes up. A missed refusal on a pile drive log, a connector that “clicked, sort of,” a bonding clamp that… Continue reading “New Free Course: 10 Utility-Scale Solar Defects Hiding in Plain Sight”
Common SCADA Problems O&M Teams Inherit and How to Fix Them When an O&M team takes over a utility-scale solar project, they’re inheriting whatever SCADA system the construction team left behind – for better or worse. Unfortunately, there can be loose connections, misconfigured device IDs, missing documentation, and more. These are… Continue reading “Common SCADA Problems O&M Teams Inherit and How to Fix Them”
