As an individual deeply committed to the Net Zero movement, I am always searching for leading edge news that can provide evidence of significant advancement in the ever-evolving Green Building arena. On rare occasion I come across something so amazingly different, so radical in concept, so potentially revolutionary, that one can’t help but think it’s too good to be true!
Enter the V3 Solar “Spin Cell”. To better understand the spin cell technology, the following is a portion of a V3 Spin Cell review provided by Bill Rever, Independent Consultant (December 18, 2012):
“The V3 Solar system is fundamentally a rotating assembly of photovoltaic cells under a structure of lenses that concentrate light onto the moving cells. The nominal shape of both the lens arrangement and the assembly of cells is conical, although this shape could be different if more optimal forms emerge in the design process. The design is referred to as the “Spin Cell”. The essential characteristics of the design are:
- Captures light from the full hemisphere of the sky to maximize the use of available insolation
- Motion of the cell assembly provides cooling solving a fundamental problem of systems using concentration
- The moving cell assembly can be used to produce an alternating current (ac) output directly without a traditional inverter
- The cooling effect is sufficient to allow for the use of mass produced one sun cells available from hundreds of manufacturers globally
- Enhanced efficiency is hypothesized via a “cascade effect” whereby cells retain and build some energy as they pass by the sequence of lenses
- The system is self-contained and doesn’t require additional racking and mounting – it can be mounted directly to earth screws, poles or other low cost foundations.”
Information provided on the V3 Solar website states:
“The Spin Cell’s ability to concentrate light dramatically reduces the amount of PV required for a given output, thus reducing the cost per watt. The improved efficiency of the PV means that less light is required to create the same amount of watts, further reducing costs and improving efficiency of the overall unit. With a 20X concentration of the sunlight, the Spin Cell can produce the same amount of power while using 5% of the PV material. Since the lensing costs 92% less than the PV material, this lowers the cost/watt.”
Some of the components are still patent pending and testing is being conducted on prototypes to verify and establish the extent of V3’s Spin Cell capability. Without doubt, this new approach to solar energy could, if testing proves out, change the course of solar technology as we know it. Flat panel manufacturers are not excited about it and have been quite vocal in their opposition to spin cell technology. Until the tests are in, we will not know for sure if this is fact or fraud. I can only hope that the technology turns out to be factual, but will reserve my endorsement until the results are in.
In the mean time . . . . I have my fingers crossed!
