Our Partnership with Blackstone

In October 2014, Blackstone announced it would create Onyx Renewable Partners. Blackstone is a leading financial institution in the private investment sector with a long history of backing power development teams.

Onyx is Blackstone’s 9th portfolio management team and 3rd management team focused on power.

Our Process

We have the capability to oversee every stage of each solar project, from development and engineering to construction and management. Our turnkey approach ensures optimal execution, high quality control standards, and accelerates time from development to operation. Our people and process ensures extensive experience at every level of the solar installation process.


There is no need for additional funding, given our access to tax equity from the world’s leading banks. Through our current business model, we have amassed a sizable portfolio of operating solar assets and are actively seeking more opportunities to grow. Due to our wealth of deployable capital, we have put together an expert team, capable of completing every stage of the solar installation process with high quality standards and close attention to detail.

Development & Engineering

We have all necessary project management, development, and engineering capabilities in-house. Our internal team of engineers work closely with customers, the utility, and local contractors to design and construct the optimal system. When it comes to designing and planning solar projects, attention to detail is crucial. With every unique project, there are unexpected hurdles; our accomplished team of engineers have seen it all and are able to solve complex issues and create solutions for the unexpected hurdles.


Our trusted national network of subcontractors and suppliers ensures complete construction capabilities. Members of our team have worked hands-on, in the field at every position—from labor to manager.

Operation & Management

We want our panels to produce as much energy for our clients as possible. Through our Operation and Management division, we deliver maximum production on all of our projects. Using state-of-the-art technology, we monitor our systems remotely, and provide live, up-to-date information to our clients.

Our Projects

We have built solar systems across the country for a wide variety of clients. We are actively seeking opportunities for growth through Greenfield Development and Mergers & Acquisitions.
