What Onyx Renewable Partners does
Onyx Renewable Partners L.P. is a U.S. distributed clean energy solutions provider founded in 2014 and headquartered in New York City. The company develops, finances, constructs, owns, and operates solar photovoltaic (rooftop, ground-mount, and carport) and battery energy storage systems for commercial and industrial (C&I) businesses, government and municipal entities, military installations, and community solar subscribers. Onyx is also expanding into EV charging infrastructure as part of a broader distributed energy resources (DER) offering.
The company's core technology is the integrated delivery and long-term operation of distributed energy assets, not proprietary hardware or software. Onyx's differentiation rests on end-to-end project lifecycle ownership — development, engineering, financing, construction, and 15-25 year operations and maintenance — and on its ability to structure PPAs, operating leases, tax equity arrangements, and ITC monetization. The operating fleet generated 237,003 MWh of clean energy in 2023, avoiding an estimated 126,151 metric tons of CO2 emissions.
Onyx's revenue model is dominated by recurring long-term contracts. PPAs (15-25 years) and operating leases provide subscription-style recurring revenue by selling electricity or renting systems to customers with zero upfront capital outlay. Secondary revenue comes from development fees, asset management fees, and tax credit monetization. The company sells exclusively through direct enterprise sales — field-based, consultative engagement targeting C-suite and facilities leadership — supplemented by developer and EPC partnerships (Sol Systems, Telyon, Atlas Renewables, SOLON, PowerFlex). Onyx is privately held and backed by Sustainable Development Capital LLP (SDCL) and Blackstone.

Revenue model
- Power Purchase Agreements (PPAs): Onyx owns and operates solar systems and sells electricity to customers at a fixed rate for 15-25 year terms. Customers pay for electricity generated onsite with no upfront capital investment required. This is the primary revenue model enabling customers to achieve immediate cost savings and long-term price stability.
- Operating Leases: Fixed monthly payments for renewable energy assets with no upfront costs or cap-ex required. Utilized when local regulations prevent PPAs or when customers prefer lease structures. Enables off-balance-sheet financing with immediate impact on facility net operating income.
- Project Development and Asset Management Fees: Onyx generates fees through development, financing, and ongoing asset management of distributed solar portfolios. The company also monetizes ITC tax credits and RECs (Renewable Energy Credits) through tax equity partnerships and direct sales.

Products and services
- Solar PV Systems On-site distributed solar energy systems including rooftop, ground-mount, and carport installations for commercial, industrial, municipal, and military facilities. Onyx designs, develops, finances, constructs, owns, and operates these assets, delivering on-site renewable electricity with zero upfront cost to the host customer.
- Battery Energy Storage Systems (BESS) Battery energy storage solutions integrated with solar installations to provide grid resiliency, energy cost management, peak shaving, and backup power capabilities for commercial, industrial, municipal, and military facilities.
- Community Solar Programs Shared solar installations allowing multiple residential and commercial subscribers to receive credits on their electricity bills without installing panels on their own property. Onyx develops and operates these remote solar projects and signs up subscribers, often through partners such as Solomon Community Solar.
- EV Charging Solutions Electric vehicle charging infrastructure integrated with on-site solar and battery storage systems for commercial properties, supporting fleet electrification and employee/visitor charging as part of Onyx's broader distributed clean energy solutions portfolio.
- Power Purchase Agreements (PPAs) Long-term agreements (typically 15–25 years) under which Onyx owns and operates the on-site solar and/or storage system and sells the generated electricity to the host customer at a fixed rate below the prevailing utility rate. Onyx provides full financing with zero upfront cost to the customer.
- Operating Leases Off-balance-sheet financing option for renewable energy assets with fixed monthly payments and no upfront costs or capex required. Used when PPA structures are not permitted by local regulations or when customers prefer a lease structure, enabling immediate impact on facility net operating income.

Onyx Renewable Partners competitors and assessment
Company assessmentDirect peers
- Altus Power: Public (NYSE: AMPS) C&I and community solar developer/owner/operator serving commercial customers with zero-upfront-cost PPAs and leases. Closest direct competitor to Onyx in business model, customer base, and product offering, though Altus is public and significantly larger.
- Cypress Creek Renewables: Large-scale U.S. distributed and utility-scale solar developer with C&I and community solar exposure. Comparable to Onyx in developing, financing, owning, and operating solar assets under long-term PPAs across multiple states.
- Pivot Energy: National C&I and community solar developer offering PPAs and subscription services to businesses, municipalities, and utilities. Direct competitor to Onyx in distributed solar development with similar zero-upfront-cost financing model.
- ForeFront Power: Developer of distributed solar, storage, and EV charging for C&I, government, education, and nonprofit customers across the U.S. Direct peer to Onyx with overlapping customer segments (municipal, enterprise) and PPA/lease business model.
Broad incumbents
- ENGIE Distributed Solar: Subsidiary of global utility ENGIE focused on commercial and industrial distributed solar and storage in the Americas. Overlaps with Onyx in C&I behind-the-meter solar development, but operates as part of a much broader global energy portfolio.
- EDF Renewables Distributed Solutions: U.S. arm of EDF Renewables developing distributed solar and storage for commercial, industrial, and government customers. Comparable C&I development model and customer base as Onyx, but backed by EDF group's substantially larger balance sheet.
- Tesla Energy (Solar + Powerwall): Commercial-scale solar and storage offering from Tesla, including commercial Powerwall and Megapack, increasingly targeting C&I and behind-the-meter applications. Competes with Onyx in the battery-enabled commercial solar and storage market, though with a hardware-centric rather than developer-OEM model.
Emerging players
- Sol Systems: Solar infrastructure investment and development firm that has partnered with Onyx (24 MW portfolio acquisition). Operates as both developer and tax equity/sponsor, with overlapping C&I and utility-scale solar activity that competes for similar customers and project pipelines.
- CleanChoice Energy: Renewable energy supplier and community solar developer where Onyx's CEO Mary Beth Mandanas previously served as EVP/CSO. Operates in adjacent distributed/community solar territory with overlapping customer and program exposure, though primarily a retail electricity supplier model.
Others
- Qcells (Hanwha Qcells): Solar module manufacturer and developer that has formed a strategic alliance with Onyx (6.2 MW Massachusetts community solar). Acts as both upstream technology supplier and downstream developer, intersecting with Onyx in distributed solar + storage project development.
