CSIRO report dispels negative myths about solar power for Australia

Solar power has bright future – CSIRO, SMH, Ben Cubby, Environment Editor, June 15, 2012  THE myth that solar power is unreliable because clouds sometimes cover the sun has been dispelled by a world-first report produced by the CSIRO. While clouds or rainy weather drastically reduce the amount of electricity produced by solar panels, intelligent management of the power grid means panels and mirrors should still supply 40 per cent of
the nation’s energy in the future, the report said.
“People are worried about the reliability with little evidence, and that is limiting solar,” said Glenn Platt, a senior researcher in local energy systems at the CSIRO. “Solar intermittency is not an issue at the moment, but when it does become an issue there are solutions available to deal with it.”

The CSIRO’s solutions involve a combination of timely weather
forecasts, storing renewable energy in batteries, and better directing
energy to where it is needed to reduce overall demand. For prolonged
rainy or overcast spells, turbines powered by gas or wind could fairly
easily make up for the slump in solar electricity.
The report, Solar intermittency: Australia’s clean energy challenge,
found that uncertainty about how to fit solar energy into existing
power grids had led some utilities in Western Australia to block solar
power because they feared it would complicate the power grid, and
possibly cause blackouts.
“Australia is already facing the situation where, in some network
areas, the installation of additional renewable generation has been
stopped,” the report said.
“This is a conservative response to a lack of information about
network problems intermittent renewable generation might cause and/or
concerns about the mitigation measures required to address them,
including cost and availability.
“This needs to be urgently addressed, through rigorous analysis of
both network simulations and trial deployments in the context of
Australian electricity transmission and distribution systems.”–csiro-20120615-20dig.html#ixzz1xtLXq1oE
