Mainstream Energy currently operates two wholly-owned subsidiaries both of which are highly respected leaders in their respective sector. The companies serve different customer groups within the solar marketplace, but leverage tools, systems, and expertise from the parent company to drive growth and excellence in quality, service, and cost.

AEE Solar Inc. is one of America's oldest, largest and most respected wholesale distributors of renewable energy systems and equipment. Headquartered in Northern California with warehouses and sales offices in Southern California, the Pacific Northwest, the Northeast, and most recently Canada, AEE Solar is a full-service distributor offering a comprehensive range of solar and renewable energy products and services to support the growth of solar contractors, dealers and installers, primarily in North America. AEE Solar is widely regarded as providing the best customer service and technical support in the industry.

REC Solar Inc., established in 1997 in San Luis Obispo, California, has grown on the strength of its professional sales-and-installation teams and strong marketing partnerships to become the largest system integrator of solar electric systems to homeowners and small businesses in California. Currently operating in ten locations in California, Colorado and New Jersey, REC Solar is expanding nationwide to bring cost-effective solar electric systems and services to business and residential consumers throughout the USA. In 2005, REC Solar integrated the assets of EcoEnergies, a Silicon Valley system integrator, into its operations.
