Solar power is coming to the fore as a major future source of global energy, experts say.
In Australia, where there are 1.2 million homes with solar panels installed on roofs, the growth of solar power has been so profound that wholesale prices of electricity have been driven low enough that few coal generators in Australia made a profit last year.
In the state of Queensland this week for several days the price of electricity, normally around $40-$50 a megawatt hour, hovered around zero.
The solar power industry is set to grow even further, with financial predictions from Bloomberg New Energy Finance suggesting that in Australia and Asia the use of rooftop solar panels could rise sixfold over the next decade.
