New KEMPER tracking system to optimise surface area yield

• Less wind resistance and shadow
• Up to forty percent more yield compared to fixed installations
• Intersolar trade fair presentation

Vreden, June 9, 2010. Turning it to your advantage – KEMPER Solar GmbH is to launch KemSWIVEL, a near-ground tracking system. Its typical round surface has a size of around three hundred square metres. The system's closeness to the ground reduces wind resistance, while reducing shadow makes the best of the surface area available. KemSWIVEL's astronomically controlled tracking system uses the installation's location, the date and the time to calculate the exact position of the sun and keep the modules in alignment, while backtracking completely prevents shadow affecting the modules. As a result, an installation of this type reaches up to forty percent more yield compared to fixed installations. Munich's Intersolar trade fair will give its visitors a perfect opportunity to find out more about KemSWIVEL and other KEMPER mounting systems at Booth 241, Hall A3, and on the open-air area at Booth 475 on June 9–11, 2010.

"Our new close-to-ground tracking system is highly suited as a solution for projects, e.g. those where you need the highest performance from a limited area," said KEMPER Solar GmbH Project Manager Alexander Lenfers. "The system's full advantage over fixed systems comes with large, even areas." As an example, PV performance reaches levels of around 43 kW peak per system in a KemSWIVEL installation with 240W modules, while the modular single or two-axis design saves space while saving cost and effort in transportation according to Lenfers.

Alongside KemSWIVEL, KEMPER will be presenting its KemTRACK 120, the first tracking system with a module area of 120 square metres at Intersolar. Compared to the smaller KemTRACK 60, 70 and 80 models, this system boasts significant increases in performance, and is suitable for string and central inverter system designs. Equipped with 240W modules, the system yields PV performance levels of 17 kilowatts peak (kWp) per tracker compared to 8.6 kWp in KemTRACK 60, 10 kWp in KemTRACK 70 and 11.8 kWp in KemTRACK 80. Control with integrated remote monitoring and backtracking ensures ideal alignment.

KEMPER GmbH, an engineering company specialising in the steelworking industry has also supplied solar products since spring 2009. Based in Vreden, Westphalia, the company aims to extend on its initial project success by significantly expanding its market share for its new business area in the medium term; to this end, the company recently founded a subsidiary, KEMPER Solar GmbH, for the solar business.
