One partner, from the first analysis to cash for your SRECs

Every step of your project, handled by us. Here's how it works, with a real project for each step.

  1. Develop

    We run the analysis and take your project from idea to a working array.

    Buy the system, or let us own it and simply pay for the power it makes. We match the deal to your budget and tax position, and invest in many projects ourselves.

  3. Build

    Turnkey construction, built to get the most power, and the most return, from every panel.

    Wilsbach Distributors, Harrisburg, PA. 1,315 kW designed into the building's roof from the start, offsetting 100% of its yearly electricity, built in 2023.

  4. Operate and maintain

    We monitor each array's output and keep it at its best, with yearly and as-needed maintenance.

  5. SRECs

    We turn your solar renewable energy credits into cash. As a registered PJM GATS aggregator and broker, we sell SRECs for over 100 MW of solar output.

    Gardens at Cross Keys, Glassboro, NJ. We took the owner through New Jersey's SREC process. The result: a 10-year supply agreement with Atlantic City Electric, which let the owner get bank financing.
