California Town Becomes “Most Solar Town In America” With 85% Solar

Nipton, a tiny Californian town in the blaring sun of the Mojave just went solar, and is likely to soon become a tourist attraction as “the most solar town in America.” The townsfolk, all thirty eight of them, just installed their own citywide supply of clean abundant solar power.

Three year old  Skyline has already snagged a $3 million developmental contract with the U.S. Department of Energy, and found $24 million in its first round of interested investors. It was among the first beneficiaries of the accelerated patent approvals by the Obama administration Department of Energy earlier this month, under the Greentech Pilot Program.

Nipton’s brand new solar installation has been engineered to produce 85% of Nipton’s electricity needs now, and if the town grows larger, with all that tourism it can now expect, it will be easy to add more. Installers will be able to build power plants more quickly using Skyline’s pre-engineered systems because the upgradeable, pre-engineered solar energy systems are modular and scalable.

This makes them faster to install, and once installed, the reflective troughs, and the tracking system, and a central passive cooling system all help the solar generate ten times the energy per unit of silicon, which also means wasting less material. Skyline squeezes every last electron out of their systems with a combination of efficiency measures.

HOW IT WORKS

Focus
Their HGS arrays comprise conventional monocrystalline-silicon panels, but these are mounted on the edge of a W-shaped configuration called a reflective rack. The two troughs that make up the rack counterbalance each other, capturing and focusing sunlight – reflecting it into the panels.

Cooling, passive
The panels are positioned so heat can escape easily, and the system is passively cooled by the air flowing through it. That leads to a higher conversion efficiency for the system, because when solar panels get too hot, their efficiencies drop.

Economical tracking
Because the system is made of reflective aluminum, rather than steel and mirrors, its light weight means it can be cost effectively mounted on a tracker, which follows the sun and exposes the panels to more sunlight throughout the day.

Pay as you go
Because the systems are small and modular, they can be combined to scale up to various-sized projects.

The company’s first demonstration project in San Jose was made up of twenty four 18-by-6-foot systems. A 1-MW system would take 500 to 600 of these units.

US Military Installs 500 MW Solar Plant

The U.S. military is tackling a new mission in the field of alternative energy, moving to power up a 500-megawatt solar facility at Fort Irwin’s sprawling desert complex in California. The U.S. Army Corps of Engineers launched its first phase of the project on October 15th, 2009. The project, located at the Army’s largest training range in California’s Mojave Desert, could grow as large as 1 GW in the future.

The companies will finance and build the plant in exchange for leasing of the military land. The project, planned for five sites over 13 years, could cost as much as $2 billion.

The solar power plant is part of the Army’s goal to meet a federal mandate stipulating a 25% renewable energy portfolio for all US government arms by 2025. This new facility at Fort Irwin will surpass the 14-MW solar plant at Nellis Air Force Base in Nevada as the U.S. Department of Defense’s largest solar power plant. The new solar plant will utilize both concentrated solar and photovoltaic cell innovation taking advantage of solar thermal’s low-cost and photovoltaic solar’s fast installation.
