Green deaths: The forgotten dangers of solar panelsBy Gavin Atkins May 17, 2011 10:04PM UTC
In recent years, thousands of solar panels have been placed on Australian roofs, and millions installed around the world. But how safe are they?
According to Safework Australia, each year about 30 Australians die in falls from a height, although the number of people involved in installing or maintaining solar panels is not broken down.
Some falls involving people installing or maintaining solar panels are not reported as part of work-related statistics, and then there are people electrocuted when they come into contact with power lines.
In California, where solar panels have been embraced enthusiastically, there has been a rash of deaths like this one, this one, and another three in quick succession. However, it is a worldwide phenomenon, so much so that statistics show roofing is more dangerous than coal mining.
Because of our propensity to put panels on roofs, solar is in fact, far more dangerous than many forms of power generation, three times more dangerous than wind power and more than 10 times more dangerous than nuclear power, by comparison to the amount of power produced.
This study puts it in perspective, using figures from the United States:
The fifty actual deaths from roof installation accidents for 1.5 million roof installations is equal to the actual deaths experienced so far from Chernobyl. If all 80 million residential roofs in the USA had solar power installed then one would expect 9 times the annual roofing deaths of 300 people or 2700 people (roofers to die). This would generate about 240 TWh of power each year. (30% of the power generated from nuclear power in the USA). 90 people per year over an optimistic life of 30 years for the panels not including maintenance or any electrical shock incidents.
There is an argument, however, that solar power may ultimately be safer than coal-fired generation because of the reduction in pollution. Ironically enough, however, solar power is far more dangerous than nuclear, even in a year when an accident like the disaster at Fukushima occurs.
