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”
What Is a Transformer, and Why Does It Only Work With AC? Transformers were one of the late-1800s developments that made our alternating current (AC) power system possible, and you’ll still find them at nearly every stage of the grid today. A step-up transformer at a generating plant raises the voltage to… Continue reading “What Is a Transformer, and Why Does It Only Work With AC?”

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”
New Course: Materials Handling Safety Every construction project runs on materials. Lumber, block, conduit, racking, pallets of modules, cases of sealant: all of it gets lifted, moved, stacked, stored, and eventually hauled away. That work happens so often on a jobsite that it’s easy to… Continue reading “New Course: Materials Handling Safety”
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”
Celebrating Top Solar Nonprofits: Tribal Energy Alternatives This summer, a crew from Tribal Energy Alternatives (TEA) spent a month in Browning, Montana, about 25 minutes from Glacier National Park and 40 minutes from the Canadian border. They were there to build solar for Blackfeet Community College (BFCC),… Continue reading “Celebrating Top Solar Nonprofits: Tribal Energy Alternatives”
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”
