Before You Begin: Assess Hazards and Plan

Walk the property and note overhead lines, skylights, fragile roofing, loose tiles, bee or bird nests, inverter locations, isolators, and emergency exits. Mark trip hazards from hoses or cables, and identify safe staging areas for tools and materials before touching any panel.

Before You Begin: Assess Hazards and Plan

Check wind, rain, and temperature swings. Wet roofs are slick, gusts unsteady ladders, and hot glass risks burns and thermal shock. Aim for early morning or late afternoon. Remember: sunlight energizes DC circuits even when the inverter is off.

Working at Height: Ladders, Roofs, and Fall Protection

Set ladders at a four-to-one angle, tie them off, and extend three rungs above the eave. Inspect feet and rails before climbing. For long durations, consider scaffolds or lifts. Keep hands free while climbing by hoisting tools with a rope.

Working at Height: Ladders, Roofs, and Fall Protection

Use a full-body harness with a shock-absorbing lanyard and rated anchor points. Maintain 100% tie-off when near edges. Non-slip shoes and temporary walkway mats protect you and the roof. A short, sure step is always safer than a long stride.

Safe Cleaning and Debris Removal

Let panels cool before washing. Spraying cold water on hot glass can stress seals and cause microcracks. Choose early morning for lower temperatures, better visibility, and less evaporation. Keep electrical components dry and direct water flow away from junction boxes.

Safe Cleaning and Debris Removal

Use soft-bristle brushes, deionized water, and manufacturer-approved cleaners. Avoid abrasives, high-pressure nozzles, and harsh chemicals that etch coatings. Gentle, repeated passes work better than force. Test a small area first and rinse thoroughly to prevent streaks and residue.

Dress for the Job

Wear UV-rated glasses, a brimmed hat, long sleeves, and cut-resistant, electrically rated gloves when handling conductors. Sunscreen and hydration matter as much as wrenches. Heat stress sneaks up fast; schedule shade breaks and listen to early signs of fatigue.

Insulated and Non-Conductive Tools

Pick 1000-volt rated screwdrivers, insulated pliers, and a torque wrench to avoid over-tightening clamps. Use tool lanyards at height to prevent drops. Remove metal jewelry, keep pockets zipped, and store meter leads neatly to avoid accidental snags and shorts.

First Aid and Emergency Preparedness

Keep a stocked kit, a charged phone, and local emergency numbers on hand. Train in CPR and shock response. For burns, cool with clean water and cover. Establish a buddy system, and rehearse how to reach the ground quickly but safely.

Scan for cracked glass, delamination, hotspots, browning, loose clamps, chewed insulation, and corroded connectors. Listen for buzzing at terminals. Watch for water tracks around roof penetrations. Small clues often reveal early failures, saving time and preventing hazards later.

Inspection, Testing, and Documentation

Use appropriately rated meters, IV curve tracers, and infrared cameras. Verify CAT ratings match expected voltages and fault currents. Keep leads short, one hand behind your back, and set boundaries for bystanders. Document readings immediately to avoid transcription mistakes.

DIY vs. Professional: Know Your Limits

Complex inverter faults, ground faults, water ingress, scorched connectors, or high roof pitches require a pro. Warranty terms may demand certified service. If you smell ozone, see arcing marks, or read unfamiliar error codes, stop, step back, and call help.
