New Business Member – MOUNTAIN VIEW SOLAR

Our latest business member is Mountain View Solar. They are now installing solar systems in our local region. What is particularly interesting about them is the focus on electric vehicle charging at your home. Chances are that if you are a commuter that drives less than 30 miles a day round-trip to work and home, then you are probably thinking about an electric vehicle.

Mountain View Solar is West Virginia’s largest solar PV installation company and has been recognized by various state and national organizations. Specializing in residential, commercial, municipal and government solar installations, Mountain View works throughout West Virginia, Maryland, Pennsylvania, and Virginia and now in Tennessee.

We now offer installation of solar-powered charging stations for electric vehicles, and have provided residential and commercial customers with a source of free fuel for their electric vehicles!

This illustrates the concept of distributed generation

I have included this entry because of Tennesseans interested in solar photovoltaic (PV) energy. Maybe a model for our state and TVA

Responding to clear customer interest, Arizona Public Service (APS) proposes a 20 MW
utility-owned residential distributed generation (DG) program that will help APS meet
the 2015 renewable energy requirement. Under this program,
APS would strategically deploy DG to maximize system benefits. APS would also support the local
solar community by competitively selecting third-party local solar vendors to install
these DG systems across APS’s service territory. To benefit all customers, APS would
install the DG on customer rooftops and on the utility side of the meter. APS would
“rent” these rooftops in exchange for a $30 per month bill credit. This simple bill credit
structure will provide all customers-including those who cannot currently afford it-an
opportunity to “go solar.”
To install 20 MW of residential DG, APS would deploy systems on
approximately 3,000 customer rooftops. On these rooftops, APS would install 4-8 kW
photovoltaic systems, depending on the roofs’ configurations. Just as APS might lease
land to locate a large-scale solar facility, APS will “rent” these 3,000 customer rooftops
for 20 years

Green Earth Solar Completes Second Project for Owner John Harrison

Harrison Dairy Solar Installation

Knoxville-based Green Earth Solar finished up the 39.6-kilowatt system in May, which is made of 128 310-watt panels and is expected to generate more than 46,000 kilowatts annually.
The installation was the second project between Green Earth Solar and Sweetwater Valley owner John Harrison. Completion comes a year after Harrison installed a 50-kilowatt energy system at his Thunder Hollow Farm.
Trevor Casey, Green Earth Solar director of sales, said implementing a green energy system took “a little under a week.” The project was funded through a $20,000 United States Department of Agriculture grant.
“I don’t have much thoughts on it because it’s pretty simple. It just sits there and works,” Harrison said, laughing. “It’s pretty straight forward. It’s one of the few things that we seem to do that doesn’t require much effort. It’s pretty effortless, I guess, is how I’d describe it.

While he doesn’t have anything currently planned, Harrison said he would keep an eye out for other opportunities to go green.
“In my case, a lot of it has to do with what else you’ve got going on with your business and what your tax situation is,” Harrison said. “If we had other needs that would do the same thing tax wise, you need to be able to take advantage of the tax credits.”

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


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.
