New Spin on Concentrated PV - V3Solar's CoolSpin produces electricity at $.08/kw

An even better solar innovation that's supposed to be available in the second quarter of this year. “Using specialized lensing and a [1 meter] rotating, conical shape, the Spin Cell can concentrate the sunlight 30X onto one sun mono PV with no heat degradation. This increases the Power Density while lowering the Total Cost of Ownership and Levelized Cost of Energy (LCOE), which is estimated to be $.08/kWh for the Spin Cell" This makes a very efficient cell (24%) at a fraction of the cost per kw and uses only 5% of PV of a flat panel to produce the same amount of power. They are also more efficient at all sun angles, meaning all day and all year. And in an earlier estimate from an article last May, the ROI was estimated to be less than 4 years. "The heat generated by the concentrated lens does not have enough time to transfer to the PV as it cycles out of the sunlight into the shade allowing the next piece of standard PV to go through exactly the same process, again, and again, and again. Constant cooling through dynamic spin creates higher power generation and longer life of the PV." V3Solar already has over 4 GW of requests for orders, which includes the U. S. Army. To put that into perspective, the US currently has about 7 GW of installed solar power capacity. (the 8¢/kWh figure is LCOE; and the BOM cost is 59 cents/Wp, including racking, tracking, and the inverter.)
