So far in the USSunPowerSolar panels were known for the industry's largest power generation efficiency of 21.5%, but the solar panel's newly announced solar panel power generation efficiency is 22.5% higher than that. Although the difference in power generation efficiency of the two solar panels is 1%, the remarkable point in Solar City's new solar panel is rather cost. It is 66 yen per 1 W, which is significantly lower than the cost for existing solar panels to generate electricity.

Solar City in 2014 is a solar cell venture'sSilevoWe acquired this technology, but Silevo's "Triex TechnologyThings that used. There are various types of solar cell structure, Triex Technology is N type silicon, passivation film,Oxide semiconductorHybrid type combining. The structure itself is the same as that of silicon semiconductors, but by combining different materials, it is expected to achieve power generation efficiency of 24% in a few years.


Moreover, Triex called "tunnel junction type solar cell" has a feature that the efficiency is not so low even if the temperature rises, and it is possible to generate power efficiently even on solar panels placed on the roof.


You can check the figure comparing the watt unit price of Kyocera and Mitsubishi Electric solar panels which does not include construction costs etc from the following. The price is cheap per watt and it is on the order of 400 yen, and you can see that "66 yen" in solar city is the price of disqualification. By acquiring Silevo SolarCity is one of only four companies in the United States "doing everything from manufacturing to sales and installation in photovoltaic power generation", it is considered to be able to realize low cost.

Currently the stage where the pilot version is being manufactured on a small scale, both of which are planned to assemble 10,000 panels a day by 2000 employees in Buffalo, New York State, USA.

Of course, even though the cost of solar power generation is relatively low, it is still difficult to disseminate it to ordinary households unless the cost is still high compared to other electric power and government subsidies are not common. A view. In this regard, SolarCity proposes "a variety of installation methods, including abandoning the image of" solar panels attached to the roof "so far and setting them for each community" on the blog.
