As reported, another accident occurred when a homeowner climbed onto the roof to remove snow from the snow-covered solar modules. In St. Martin im Mühlkreis on Friday, a pensioner fell seven meters and was probably seriously injured. He had to be taken to a hospital in Linz by emergency helicopter, the police said.
“It’s generally not a good idea to climb onto the roof; you should only do that with appropriate security,” warns Wolfgang Denk, spokesman for Netz Oberösterreich. It’s not just ice and snow that poses a risk of falling, you also run the risk of getting caught in the PV system’s circuit.
“Electricity yield is far too low anyway”
Removing snow from the solar panels doesn’t pay off, says Denk. The panels could be damaged and the solar power output is much lower in winter because of the low position of the sun. “On a cloudy, overcast winter day, you only generate a few watt hours with which you cannot cover any demand. In other words, whether the yield is almost zero or zero when there is snow on the solar system makes almost no difference According to experts, 70 percent of solar power in Austria is produced in the summer, the rest occurs in autumn and winter.
