Elon Musk Says Tesla’s New Solar Shingles Will Cost Less Than a Regular Roof

http://for.tn/2g1GrVO

Why would you get anything else? Musk said, minutes after the Tesla-SolarCity deal was approved.

Just after a majority of Tesla Motors TSLA -1.94% shareholders approved plans for the all-electric automaker to acquire solar energy firm SolarCity SCTY -0.29% , Tesla CEO Elon Musk dropped one of his famous bombshells, this time about the companys new solar roof product.

He told them that the companys new roof would actually cost less than traditional rooftop shingles to make and install, according to Bloomberg.

Electricity is just a bonus, the billionaire told the crowd.

So the basic proposition will be: Would you like a roof that looks better than a normal roof, lasts twice as long, costs less andby the waygenerates electricity? Musk asked. Why would you get anything else?

While Teslas solar shingles are expected to still be considered a premium product at rollout, Bloomberg reports that the company expects they would incur lower production costs than traditional roof tiles. A large part of these savings stem from the carmakers anticipation that its roofing, manufactured by Teslas new automotive and solar glass division, would be lighter and easier to ship, thus reducing costs on breakage and transportation.

First unveiled at a Tesla event on Oct. 28 to great fanfare, the roofing material jointly developed by the carmaker and SolarCity would look just like any other premium roof tiles, while doubling as solar panels for power generation.

The shingles would reportedly feature tempered glass made by Tesla, a new solar film from 3M MMM 0.11% specifically designed for this project, as well as solar power technology jointly developed by Tesla, SolarCity and Panasonic. The idea is to make solar-paneled roofs as appealing as electric cars, Musk said at the event.

Teslas merger with SolarCity was approvedoverwhelmingly by an 85% majority of unaffiliated shareholders, according to the company. Growing concerns over potentialsafety issues related to its touted Autopilotdriver-assistance feature, as well as uncertainty over federal tax breaks for electric cars under the incoming U.S. administration, has left the automaker in a tough spot this year, according to Reuterssending its stock price tumbling by almost 20% this year.

Black Silicon Can Take Efficiency of Solar Cells to New Levels

Jan. 18, 2013 — Scientists at Aalto University, Finland, have demonstrated results that show a huge improvement in the light absorption and the surface passivation on silicon nanostructures. This has been achieved by applying atomic layer coating. The results advance the development of devices that require high sensitivity light response such as high efficiency solar cells.

Jan. 18, 2013 — Scientists at Aalto University, Finland, have demonstrated results that show a huge improvement in the light absorption and the surface passivation on silicon nanostructures. This has been achieved by applying atomic layer coating. The results advance the development of devices that require high sensitivity light response such as high efficiency solar cells.

“This method provides extremely good surface passivation. Simultaneously, it reduces the reflectance further at all wavelengths. These results are very promising considering the use of black silicon (b-Si) surfaces on solar cells to increase the efficiency to completely new levels,” said Päivikki Repo, a researcher at Aalto University.

More effective surface passivation methods than those used in the past have been needed to make black silicon a viable material for commercial applications. Good surface passivation is crucial in photonic applications such as solar cells. So far, the poor charge carrier transport properties attributed to nanostructured surfaces have been more detrimental for the final device operation than the gain obtained from the reduced reflectance.

Black silicon can also be used in other technologies than solar cells. Numerous applications suggested for b-Si include drug analysis.

Black silicon (b-Si) has been a subject of great interest in various fields including photovoltaics for its ability to reduce the surface reflectance even below 1 per cent. However, many b-Si applications — especially solar cells — suffer from increased surface recombination resulting in poor spectral response. This is particularly problematic at short wavelengths.

Advantages Of Solar Power

Solar power systems have many benefits. They are quiet. They don’t produce any pollution. They are reliable, there are no moving parts to worry about, so they require minimal maintenance. Another great advantage of a solar power system is that it’s modular. The cells (or building blocks) are available in a wide variety of wattage, ranging from a mere fraction of a watt to more than 300 watts. Large solar power plants have higher megawatts, but most individual systems are much smaller. You can choose the solar power modules required to deliver the power you desire for your system.

One downside of solar energy is that much of the sun’s energy is lost during the process of transferring sunlight to electricity. To solve this challenge, larger and more efficient panels continue to be manufactured all the time. And while they are still less efficient than they ultimately might be, they are still the renewable energy system of choice because they require so little maintenance and are quite durable.

A solar panel system should last around fifty years, as long as it was properly installed. A pretty wise investment, all things considered! If you choose to install your own solar power system, you will appreciate its quiet, low-maintenance, pollution-free, safe and reliable operation, as well as the degree of independence it provides.

A cool new Solar design from V3 Solar

CoolSpin

V3Solar’s patented spin technology is a new paradigm that covers any spinning PV form factor. The second iteration of this revolution is the V3 CoolSpin, which competes directly with existing one sun mono PV solar panels with lower cost of components (34% lower) while providing far more effective and simpler energy production.

The CoolSpin product has been designed to be “plug compatible” with existing one sun solar cells. The CoolSpin can be made to fit existing bracketing and tracking products in the solar industry.

CoolSpin will be available for licensing from the second quarter 2013, with mass production planned the third quarter.

Main CoolSpin Benefits:

  • lower cost per watt (34.3% less than 1x sun solar panels)
  • only requires a single axis tracker with linear Fresnel (cost savings)
  • high tolerance to off axis tracking alignment
  • dramatic reduction in amount of PV required per watt
  • lower operating temperatures could lead to higher net efficiency

Through the patented CoolSpin technology energy is constantly provided from one sun mono PV that remains cool from the spin. 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.
