Living Light Solar House moves to Oak Ridge’s Children’s Museum

The Living Light Solar House, designed by more than 200 UTK students, has been donated by the University of Tennessee to the Oak Ridge Children’s Museum. The home is 750 square feet and is a zero-energy structure, providing an example of what energy efficient housing could look like in the future. Originally produced to compete in the U.S. Department of Energy Solar Decathlon, the house will now serve as an educational and inspirational tool for children and visitors to the museum.

SolarCity follows Tesla’s “Gigafactory” path, will manufacture own solar panels

GigafactorySolarPlant

SAN MATEO—In a recent move by SolarCity, the company will attempt to bring solar energy into the hands of a much larger portion of the population. Currently, photovoltaic solar panel systems are out of reach for many people because of their prices, forcing them to continue to rely on energy produced using fossil fuels. However, SolarCity’s goal is to change this, producing solar energy grid components on such a large scale that their prices will become low enough so as to become more economically viable than fossil fuels. In order to achieve this goal, SolarCity has purchased Silevo, a solar panel manufacturing firm, which SolarCity will expand, opening a new manufacturing plant in New York, and potentially more in the future. SolarCity will target a true “Gigafactory” to produce more than a gigawatt of solar power capability.  “What we are trying to address is not the lay of the land today, where there are indeed too many suppliers, most of whom are producing relatively low photonic efficiency solar cells at uncompelling costs, but how we see the future developing,” the company’s blog post read. “Without decisive action to lay the groundwork today, the massive volume of affordable, high efficiency panels needed for unsubsidized solar power to outcompete fossil fuel grid power simply will not be there when it is needed.”

Silevo is known for its ‘tunneling junction’ solar cell structure.  Combining the benefits of increased carrier generation, back of the cell contacts, matrix redundant cell connections, and eliminating bussbar current collection will create the next generation of silicon solar cells and panels that will reduce the cost of the panel by increasing the overall efficiency.  The target is rooftop solar which is the kernel of SolarCity’s business.

With TVA sales on the down side, it would be a great coup if TVA could entice SolarCity to build a plant here in Tennessee.  One gigawatt sized factory would create a $200 million yearly income for TVA and employ hundreds of workers with high paying manufacturing jobs.
