Canadian Solar Introduces Intelligrated™ Power Product Featuring New CommercialAC Module

CommercialAC Integrates Specially Designed Solar Module with New Three-Phase Sequenced Inverter Technology – Check It Out at Solar Power International 2011 in Booth #2516

SAN RAMON, Calif.—October 12, 2011—Canadian Solar, Inc., (the "Company," "we" or "Canadian Solar") (NASDAQ: CSIQ), one of the world's largest solar companies, today launched its Intelligrated™ Power module series.

Intelligrated Power integrates the intelligence of panel electronics with specially-designed modules to deliver state-of-the-art features that maximize system performance, simplify installation and improve safety, significantly reducing cost of design and installation. The first product in the line, CommercialAC, integrates module and inverter into one high-performing module that dramatically simplifies commercial system design and installation. Beginning with CommercialAC, the complete Intelligrated Power product offering will eventually support all market segments. Canadian Solar is unveiling Intelligrated Power's CommercialAC at the Solar Power International 2011 conference in Dallas on October 17-20.

"The global solar market demands constant innovation and improvement of technology, performance, pricing and safety. Our Intelligrated Power CommercialAC module introduces a new technology that meets and exceeds current commercial solar market demands," said Dr. Shawn Qu, CEO of Canadian Solar.

CommercialAC is the first three-phase grid-ready AC solar module and inverter combination designed specifically for commercial installations. Integrating Canadian Solar's specially designed solar module with the new sequenced inverter technology, the AC module dramatically simplifies system design – with no need for central or string inverter, or module and string sizing.

Built with new hot spot suppression technology that eliminates diodes, the rugged inverter components are more reliable and durable than standard microinverters. CommercialAC is inherently safe with no high-voltage DC and no arc faulting. The "plug and play" module simplifies design and on-the-spot system modifications reducing the need for highly skilled labor while at the same time providing cost savings on design, labor and balance of system.

The CommercialAC module and sequenced inverter are covered by Canadian Solar's industry-leading 25-year warranty. In addition, CommercialAC is "double protected" by matching warranty insurance underwritten by A.M. Best-rated insurance carriers.

Intelligrated Power CommercialAC modules will be available in early 2012 and on display at Solar Power International. Visit Canadian Solar booth #2516 in Hall C for a sneak peek of the new CommercialAC modules.
