Who We Are

Sky Clean Energy Ltd. (SKY) began as a solar developer, employing business development, project management and engineering expertise to create custom solar installations and become a leader in Canada’s solar industry. Formerly known as Sky Solar (Canada) Ltd., SKY recently changed its name to reflect a broader business strategy in the clean energy industry.

SKY was incorporated in April 2009 and is based in Markham, Ontario. Project development often involves collaboration between the teams at SKY and its US affiliate, Sky Solar Inc (SSI), which was formed in January 2010 and operates out of New Jersey.

SSI and SKY are both subsidiaries of Sky Solar Holdings, Ltd (SSH). SSH is a global independent power producer (“IPP”) that develops, owns, and operates solar parks and generates revenue primarily by selling electricity. It is a publicly traded company (NASDAQ: SKYS).

SKY’s senior management is comprised of individuals who have extensive experience in the operations of both SKY, SSI, and parent company SSH.
