Canadian Solar, Inc., (the "Company," "we" or "Canadian Solar") (NASDAQ: CSIQ), one of the world's largest solar companies, today launched its new ResidentialAC module, the latest addition to the Intelligrated™ Power product family, at Solar Power International 2012.

Intelligrated Power integrates the intelligence of panel electronics with high performance solar modules to deliver smart, state-of-the-art solar power products that maximize system performance while significantly reducing the cost of system design and installation. ResidentialAC is a revolutionary AC solar energy solution with advanced technology that delivers a double-digit increase in solar power production over traditional micro inverters. Pre-installed at the factory, ResidentialAC's advanced inverter technology was designed and built from the ground up, with a core focus on performance and longevity. The technology eliminates life-limiting components, dramatically increasing the inverters' life expectancy. The Canadian Solar AC solar solution eliminates the danger of high voltage DC power and wiring for safer, easier installation.

"ResidentialAC offers our residential customers a simple, elegant AC solar solution that delivers high quality performance at a cost-effective price point," said Dr. Shawn Qu, CEO of Canadian Solar, "We are excited to launch a solution that provides our customers with the smartest solar solution for reliable home installations and reinforces our leadership as cutting-edge innovators in the solar industry."

ResidentialAC' s voltage-safe "plug and play" technology is easily configurable to any desired system size, allowing on-the-spot system modifications and eliminating the necessity for highly skilled labor. The module is covered by Canadian Solar's industry-leading 25 year warranty and is "double protected" by matching warranty insurance, guaranteed by three of the world's top-rated insurance carriers. Monitoring software is included, allowing customers module-level tracking of solar panel performance to optimize the system's solar energy production.

ResidentialAC

Available in a sleek black frame, the ResidentialAC module is designed specifically for home and business solar installations. It increases system performance with advanced technology, shade tolerance and no module mismatch, delivering higher energy production than standard micro inverters. The new AC modules are safer and easier to install than traditional technologies, reducing costs on design, labor and balance of system.
