The Crystalline Modules of KYOCERA Solar Perform Well at Desert Knowledge Australia

published: 2010-11-08 15:28

Alice Springs, Australia, with around 300 days of sunshine every year, is an ideal test location for solar power installations. The Desert Knowledge Australia (DKA) Solar Centre is a government-funded public showcase of solar installations, demonstrating a range of solar power technologies from many of the world's leading manufacturers.

This collection of solar installations operating under the same environmental conditions since October 2008 allows meaningful comparisons of performance among various brands.

Desert Knowledge Australia Solar Centre is not a research facility, but rather a public installation to demonstrate solar power, with output data available to anyone. Kyocera's interpretation of data collected during a 24-month period and downloaded from DKA shows that Kyocera solar technology delivered more kilowatt hours per installed kilowatt than any other competing crystalline solar module operating for the same 24-month period at the DKA site.

Kyocera has three polycrystalline silicon solar installations at DKA: a fixed pole-mount system; a single-axis tracker that adjusts east-west orientation throughout the day; and a dual-axis tracker that adjusts the array's up-and-down tilt, allowing for variation in the sun's angle during the year as well as moving from east to west throughout the day.

In addition to its interpretive visitor center, which helps educate the public about the benefits and capabilities of solar power, DKA has a world's-first interactive website providing live data feeds from the Solar Centre and information on the operational performance of the different solar technologies. This information is available for viewing by the public — anyone, anywhere, can access it. It is important to look at the Normalised Output tab to view the actual "kilowatt hours generated" per kilowatt of modules installed. This allows comparisons between the different-sized systems.

Kyocera's interpretations contrast with the old belief that monocrystalline silicon solar cells, which are more expensive, may outperform polycrystalline.

"We believe there is an important difference between lab test conditions and real-world results," stated Michael Ludgate, Kyocera Solar, Inc.'s Director of Business Development and Marketing. "The live data feeds from the DKA Solar Centre provide the industry with long-term, system-level data that prove the reliability and performance of solar installations in real-world applications."

The dual-axis tracking system performed best among Kyocera's three installations. Since solar panels generate the most electricity when light hits their surface directly, adjusting the surface to follow the sun increases their electrical output. The dual-axis trackers respond to light sensors on the face of the array, and are powered by the sun.
