A new dimension for solar energy

Intensive research around the world has focused on improving the performance of solar photovoltaic cells and bringing down their cost. But very little attention has been paid to the best ways of arranging those cells, which are typically placed flat on a rooftop or other surface, or sometimes attached to motorized structures that keep the cells pointed toward the sun as it crosses the sky.
”"
Now, a team of MIT researchers has come up with a very different approach: building cubes or towers that extend the solar cells upward in three-dimensional configurations. Amazingly, the results from the structures they’ve tested show power output ranging from double to more than 20 times that of fixed flat panels with the same base area.For more on this please click here

Power Tower and Salt Storage

With approval of the Environmental Impact Review on its 200-megawatt, two-tower Saguache Solar Energy Project, SolarReserve hopes to soon get started on a new pair of solar power tower/molten salt storage facilities.”"

“This is the major environmental permit,” SolarReserve CEO Kevin Smith said. “The bigger issue, in order to start construction, is we need to secure an offtaker.” CEO Kevin Smith also stated that his solar power tower and molten salt storage system is “less expensive, more efficient, and technically superior.”

SolarReserve’s flagship 110-megawatt Crescent Dunes Solar Energy Plant in Nevada has a power purchase agreement (PPA) with Nevada Power and is under construction and scheduled to come on-line at the end of 2013. For more information please click here.
