Last year I installed 40 solar panels completely by myself and never fell. My dad and I built a lean-to and I installed 14 more panels. Crazy this happened. I really did not per say fall off the ladder legs went out and surfed that bad boy to the wooden deck. The top of the ladder scraped down the side of the house destroying 2 pieces of vinyl siding along the way. But I wouldn’t say I was hanging 10.
