"It’s a cool and sunny morning out near the small community of Carwarp in
western Victoria, and RayGen CEO Richard Payne is pleased. But he’s got a
nervous eye on the clouds rolling in from the west.
The four solar towers and their attendant rows of heliostats (giant mirrors)
look stunning in the morning sun, and Payne wants that to be the case when the
deputy energy minister Jenny McAllister and other dignitaries arrive in a few
hours to cut the ribbon and declare one of Australia’s most innovative
renewable projects open.
It’s not that Payne is worried about the old hoary chestnut of “when the sun
don’t shine”, his concern today is about getting the right “photo-op”.
The real beauty of this Carwarp solar project is that RayGen needn’t be
bothered by intermittent cloud cover because it claims to have solved one of
the big challenges of concentrated solar projects, or any renewable project for
that matter – how to deliver cheap and efficient deep storage.
It’s been a long journey since RayGen founder John Lasich first began working
on his unique concentrated solar PV technology decades ago. Now, In a module
the size of the palm of your hand, it holds as much capacity (2.5kW) as many of
the conventional PV modules mounted on the rooftops of Australian homes.
But how to deliver this power at competitive prices has been the challenge.
RayGen experimented by mounting the modules in giant dishes, before putting on
the top of solar tower, with rows and rows of heliostats (effectively big
mirrors) that track and reflect the sunlight on to the receiver."
