NRG Buys Installer Roof Diagnostics in Home Solar Push

NRG Energy Inc., the largest independent U.S. electricity producer, bought rooftop solar installer Roof Diagnostics Solar Inc. as it seeks to capitalize on the growing decentralized power market.

Roof Diagnostics will be re-branded as part of NRG’s existing solar installation unit, Princeton, New Jersey-based NRG said in a statement today. Terms weren’t disclosed.

Self-generation using solar panels is becoming competitive with the retail price of power in many states, reaching half of all states by next year, NRG Chief Executive Officer David Crane said yesterday in an interview.

Crane outlined plans to accelerate NRG’s shift into a more distributed generation model and the purchase of companies such as Roof Diagnostics.

NRG “wants and expects to meet the demand of Americans in every state” while “affording themselves greater independence from an increasingly less reliable electric grid,” he said.

The 475-employee company headquartered in Wall Township, New Jersey will complement and be rolled into NRG’s existing rooftop unit NRG Residential Solar Solutions that mainly consists of licensed dealers.
