CAMBRIDGE, Mass. 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 theyve tested show power output ranging from double to more than 20 times that of fixed flat panels with the same base area.

Oil and Gas will soon give way to new paradigm.

Sadly, it's being misunderstood to mean solar panels that are far more efficient but you can see even from the model that they are using ordinary PV cells.
Sure, more power per footprint area is all, but by no means is it more power per dollar spent or per surface area of PV material.
Cool, but misleading, I'm afraid.

(29,798 posts)Not only would it be easier to track the sun through the day but it looks like the angle could be maintained at optimum for the time of year.

the drawback is more weight per square foot or meter or inch or whatever.
This would make a nicer collector for solar streetlights....no big wing of a collector on a little post. Better against wind sheer, too.
It's nifty for space problems!
Classic solar cells are still the gold standard for output, lifetime, and so on.

(29,798 posts)The amount of force it will have to withstand from wind on the panels would probably rule out any rooftop install.
