What are the risks associated with solar energy?
There are roughly two types of solar power: Thermic (Solar
heating) and Electric (PV)
Risks are only the risks like handling any kind of powered
equipment generating/using heat or electricity.
So Solar heating heating can cause fire, stream burns (As used
by concentrating solar mirrors) , mechanical overload. PV can cause
electrocution and fire by short circuit.
By comparisment with other ways of power production the risks
are lower. There is no fuel that can burn/explode and no waste that
is either toxic or radioactive.
