story about solar starting to break into the mainstream

Home Depot expands its solar service offerings to the East Coast by partnering with two other fast-growing providers, Sunrun and Clean Power Finance.
The experience of Roof Diagnostics Solar — a leading contractor partnering with Sunrun, Clean Power Finance, and Home Depot on the East Coast — offers a window into how these arrangements are boosting solar sales.
A year and a half ago, Roof Diagnostics participated in a Home Depot pilot program with one other company in fourteen New Jersey stores. It set out a kiosk with a laptop, 40-inch television, and a solar specialist who could do a simple assessment of a home from the store.
The immediate reaction was “explosive,” said Pegler Jr., with 68 sales coming in the first 60 days. A couple weeks later, they were given twenty-one stores. And the company will be offering solar in 100 locations by the end of the year in New Jersey, New York, Pennsylvania, and Massachusetts — with most of those kiosks located in the first aisle of the stores.

Four out of every ten people who visit the Home Depot kiosk sign up for a solar lease or power purchase agreement with Roof Diagnostics. Pegler Jr. believes it’s a sign that the Northeastern solar market is maturing. Because states like New Jersey, New York, Pennsylvania, and Massachusetts have strong solar programs, consumers generally know about the opportunity. But seeing a kiosk in a Home Depot store can be the difference between someone thinking about solar and actually taking action.

42nd National Solar Conference, SOLAR 2013, in Baltimore, April 16-20

Register today at the American Solar Energy Society for the conference details and sign up.

Highlights of the technical session include:
New techniques for making high-performance quantum-dot and nanoparticle photovoltaic cells.

The status of the High Definition PV project, an industry-wide program to reduce the cost of solar installations through plug-and-play standardization.

Several new techniques to reduce the cost of dispatchable power from concentrating solar thermal (CSP) plants, a key development in providing cheap, clean solar power to run municipal grids through the night.

Solar-powered furnaces that generate hydrogen or syngas fuels at high efficiency.

A wide variety of simplified techniques for minute-to-minute and hour-to-hour forecasting of solar farm output, useful for balancing loads across geographic regions.

Efficient new ways to store solar-heated hot water – and use solar heat to drive air conditioners.

Cheap feedstocks for cheap biodiesel.

Hybrid light rail that runs when the grid goes down.

Driving large desalination and waste-water recovery systems with renewable energy.

Promoting Solar PV Deployment Through Micro-Investments

This conference is hosted by the American Solar Energy Society to which TSEA is the Tennessee State Chapter. Established in 1954, the nonprofit American Solar Energy Society is the nation’s leading association of solar professionals and advocates. Our mission is to speed the transition to a sustainable energy economy.

New Thin-Film Solar Cell May Provide Electricity at Grid Parity Using Gallium Arsenide Solar Cells

Global Photonic Energy Corp. (GPEC), has created a thin-film solar cell that has the ability to provide electricity at grid parity or the cost of traditionally provided electricity.
Gallium Arsenide (GaAs) is a better photovoltaic candidate than silicon reaching 30% or better efficiency. Problem with Gallium Arsenide cells is that they are very expensive to manufacture in large sizes. Instead these cells are used in concentrating solar PV arrays where the sun image is concentrated some 500 times focusing the light onto a small millimeter sized GaAs cell.

Dr. Stephen R. Forrest of the University of Michigan said the breakthrough, presented at the Fall Meeting of the Materials Research Society, is the result of substantially reduced production costs. It is based on a patent-pending invention that reuses the same Gallium Arsenide wafer multiple times to produce solar cells. This unlimited wafer reuse approach to conventional “epitaxial lift off” technology that typically leads to wafer damage, and hence only a very limited number (1 to 2) of wafer reuses, has the potential to reduce the cost of a typical Gallium Arsenide solar cell to below $1 per Watt (peak).

“This exciting development implies that ultra-high efficiency solar cells based on Gallium Arsenide can eventually produce electricity at or below grid parity.” Dr. Forrest stated. “Using integrated solar concentrators and our adhesive-free, cold-weld bonding technology to plastic substrates, we estimate electricity could be produced as low as $0.45 cents per Watt, compared to traditional grid parity of $1 per Watt.”

GPEC is excited by the discovery. With this new discovery, the cost structure is dramatically reduced and can be used in numerous applications. The high efficiency, light weight and flexible solar cells are deployed on roll up plastic sheets. GPEC anticipates their use in spot powering vehicles, mobile military equipment and satellites, and off-grid locations. The company has big plans and want to license its intellectual property in order to commercialize the technology. To date, GPEC has a total of 425 patents.

Latest NREL Report Suggests that Tennessee Has a Solar PV Potential of 20 Times the Amount of Electricity Used in the State

In a government report from the National Renewable Energy Laboratory demonstrates the tremendous potential for solar energy generation in Tennessee. The report estimates the technical potential of solar PV as well as other renewable power sources for the production of electrical power. It is a study of the potential based on renewable resource availability and quality, technical system performance, topographic limitations, environmental, and land-use constraints only. The study does not consider the economic, political or market constraints. In 2010, Tennessee used 103,522 GWh (103,522,000,000 kWh). The report estimates that the total solar potential including rural and urban utility-scale PV as well as roof-top solar would amount to 2,295,918 GWh.

Latest Generation Of Disruptive Solar Technologies

The grid shows that innovations in materials and cell designs will help stabilize module prices at $0.90/W, while the cost of goods sold will fall on account of improved cell efficiencies, cheaper processes and thinner wafers. Among other findings, the report predicts that direct solidification will provide cheaper wafers, and that direct solidification of molten silicon offers the best way toward kerfless wafering (which eliminates losses from sawing). This technology is a top target on the Disruptive PV Technology Grid, with a market size of up to $600 million. 1366 Technologies is the clear leader and is expected to be the first to reach commercialization by 2013, according to Lux Research.

Alternatives to cell efficiency will increase. Anti-reflective and light-trapping coatings are second-tier technologies, but they are among the top targets, with a market size of more than $600 million. These technologies provide cost-effective alternatives for efficiency gains. According to Lux Research, Natcore is the leader in this space with likely commercialization this year.
