Xtreme concentrated photovoltaics™ (XCPV)

SUNRGI alleges that their propriety technology makes it possible to produce large amounts of electricity from solar radiation at a whole sale price of US $0.05 / kWh.

With a 2000x magnification, the system is called Xtreme Concentrated Photovoltaics™ or XPV™, concentrating sunlight onto photovoltaic (PV) solar cells that convert more than 37% of the sunlight directly into electricity. The system also includes a method of pulling the heat away from the area of focus to prevent the PV cells from burning up.

The final aspect that allows for an inexpensive energy price is low cost mass production and field installation.

They expect to begin production of a commercial product by mid-2009.

"ENTERTAINMENT TONIGHT, the most watched entertainment news program in the world, will broadcast a feature story about SUNRGI on MONDAY, MAY 26, 2008.

"NEWS ABOUT SUNRGI: When SUNRGI announced its breakthrough solar energy system that makes it possible to produce wholesale electricity at a cost competitive with fossil fuels, thousands of web sites and hundreds of newspapers published stories about the news. SUNRGI.com became one of the most visited web sites on the Internet and its video animation was the most-viewed viral video of the day."

How it Works

SUNRGI's proprietary (patents pending) COOLMOVE ™ heat transport technology swiftly prevents this undesirable heat buildup to that the PV solar cells are actually kept cooler than their nominal operating temperature, thus extending their useful life. [1]

A dual tracking system enables 175% more sunlight to be gathered during a day. [2] [3]

Optimizing solar concentration, heat removal, component reduction and highly accurate solar tracking will make it possible, in about a year, for SUNRGI technology to produce large amounts of electricity from sunlight at a wholesale cost of 5 cents per kWh. [4]

The real estate needed for energy generation with the SUNRGI system will be 16 times less than thin film solar technologies. [Comment: Since thin film is now at 19% efficiency, the real estate would be half that of thin film, not 1/16.]

Costs

Alleges 5 cents/kw-h, which is in the range of being competitive with fossil fuel power. This is large-scale pricing. Residential applications will not be this cheap yet.

Initially, SUNRGI will target large institutional and corporate customers, including utility companies, government institutions, systems integrators and those companies and projects which have large-scale, renewable power requirements.

Advantages

http://www.sunrgi.com/technology.html

• On and Off-Grid Distribution - Other solar technologies, solar thermal in particular, need to be implemented as part of large power stations. SUNRGI’s system however, can be deployed in small configurations allowing lower and more variable entry points into the solar market. SUNRGI can provide discreet, off-grid “power plants? that can be sited in any sun-suitable location.

• Modularity - SUNRGI’s modular design modular enables a power station to be distributed over a number of sites. A large power station can be divided into a number of sub-stations which makes for easier access to suitable land.

• Upgradeability - Unlike traditional PV technology, SUNRGI’s design is upgradeable, allowing it to take advantage of future advances in PV technology.

• Concentrated - Energy Since the sunlight is concentrated, fewer PV cells are needed thereby reducing the cost-per-watt of generated electricity. Also, it is more efficient format from which to extract heat.

• Longevity - With SUNRGI’s proprietary heat removal technology the PV cells have a longer useful life.

• Economy - SUNRGI’s system costs significantly less per installed Watt than traditional PV technology. Expected advances in technology, maturity and volume production will further increase this cost advantage.

• Not Silicon-Dependent - SUNRGI XCPV technology does not depend upon silicon, and therefore is not affected by this shortage.

Independent Testing

XCPV prototypes have been built and successfully tested under both laboratory and field (outdoor) conditions.

Profiles

Company: SUNRGI LLC

SUNRGI is in the business of designing and developing solar energy systems. It was formed by five, experienced, entrepreneurial, inventive individuals with the goal of creating a renewable energy source that would be available at fossil fuel prices. Its work has led to the development of an entirely new solar energy category: Xtreme Concentrated Photovoltaics™ or XCPV™. SUNRGI maintains offices in Reno, Silicon Valley and Los Angeles. [5]
