Canadian Solar Supplies ELPS Solar Modules for 1.3 MW Solar Power Plant.


Canadian Solar supplied 1.3 MW of its ELPS solar modules for the ground-mount PV installation in the city of Sulzbach. The system was connected to the grid on September 3, 2012 and was one of the first projects in Germany to use modules equipped with Canadian Solar’s ELPS solar cell technology.

The site of the solar park is on a north-facing slope so the requirements for the modules' performance and quality were particularly high. This is why Canadian Solar ELPS CS6P-MM modules, consisting of 60 pieces of mono cells and with power of 265 W, were selected for the job. Thanks to the metal-wrap-through (MWT) architecture used in the ELPS cells, each solar cell can absorb 3 percent more light and, as a result, ELPS solar modules produce more power than conventional modules.

“Within its first three weeks of operation, the system produced 110,000 kWh of power – despite its north-facing position. This is proof the decision to use ELPS modules was the right one,” said Karl-Heinz Sedlmaier, the solar park’s operator.

“With our ELPS technology, we took a major efficiency leap forward. ELPS modules also show outstanding performance under suboptimal radiation conditions, as the Sulzbach project proves,” said Dr. Shawn Qu, Chairman and CEO of Canadian Solar.


The ELPS cell technology is proprietarily to Canadian Solar. It is a back-contact cell technology using P-type crystalline-silicon and a metal wrap-through design. This innovative cell technology significantly increases cell efficiency – in-house tests found that the mono ELPS solar cell efficiency reached 21.1 percent, which Canadian Solar believes to be the highest performance level available for a P-type mono-crystalline cell at time of installation on this project.
