RGS Energy RGSE, +4.88% one of the nation’s largest and most recognized rooftop installers of solar equipment, has signed a partnership agreement with Centrosolar America, a provider of premium roof-based PV systems, components and turnkey projects.

The partnership will expand RGS Energy’s capacity for solar installations on the East Coast by approximately 1-2 megawatts (MW) per month beginning in the second quarter of 2015.

Centrosolar will make available to RGS its full range of turnkey products and logistic services as well as its network of solar installers for deploying RGS Energy’s residential solar projects. The additional capacity allows RGS Energy to better address its large installation backlog on the East Coast and facilitate possible expansion into other states.
