Spinning solar cells generate 20x more el.

Cone shaped spinning solar cells generates 20 times more electricity than flat solar panels. Every now and then a design comes along that just turns he whole world upside down with a claim so fantastic it’s hard to believe. But yes, from everything we’ve been able to find on this device, this the real deal.

It’s a conical shaped collection of photovoltaic cells arranged in an angular array. The array is designed to be the most efficient way to capture the sun’s energy. In traditional solar arrays with flat panels, one must adjust the angle of the solar panels individually. This design takes advantage of a conical shape which is conducive to collecting maximum sunlight from any angle at any time of year.

Tesla’s Solar Roof is coming

Tesla’s Solar Roof is coming

On Friday evening as the sun descended over the old Hollywood set of “Desperate Housewives,” Elon Musk took to a stage and fired up his presentation about climate change. It was a strange scene, with hundreds of people crowded into the middle of a subtly artificial suburban neighborhood.

It wasn’t until about a minute into the speech that Musk casually let the crowd in on Tesla’s big secret. “The interesting thing is that the houses you see around you are all solar houses,” Musk said. “Did you notice?”

The answer, in short, was no. Like everyone else, I knew we were there to see Musk’s new “solar roof,” whatever that was supposed to mean. But try as I could as we walked in, I didn’t see anything that looked like it could carry an electric current. If anything, the slate and Spanish clay roofs looked a bit too nice for a television set. This is the future of solar, Musk proclaimed. “You’ll want to call your neighbors over and say ‘check out the sweet roof.’ It’s not a phrase you hear often.”

The roof tiles are actually made of textured glass. From most viewing angles, they look just like ordinary shingles, but they allow light to pass through from above onto a standard flat solar cell…

By using a high efficiency Multijunction cell, the cell surface is reduced down to 1 % compared to the same power output as a conventional silicon cell in optimal conditions. In combination with dual axis tracking, the system generates twice the yield of a conventional panel.
