Solar as a Revenue Stream: Lease vs. PPA vs. Direct Purchase
For commercial property owners, solar is more than a sustainability initiative—it is a strategic investment. With electricity costs on the rise and sustainability becoming a core business priority, the key consideration is no longer whether to pursue solar, but rather which properties are ideal candidates and which financial structure best supports execution.
The optimal approach often comes down to selecting the right model: a site lease, a power purchase agreement (PPA), or a direct purchase.
At Plankton Energy, every solar system and financing structure is tailored to the specific goals, budget, and timeline of the property and ownership team. The following outlines how each structure can drive financial and environmental performance.
Site Lease: No CapEx, Guaranteed Revenue
Under a Site Lease Agreement, Plankton leases rooftop or parking lot space to host a solar array. Plankton owns, operates, and maintains the system, while the property owner earns passive income with no upfront investment.
Best suited for:
- Owners seeking to monetize underutilized rooftop or parking space
- Properties in jurisdictions with strong markets for offsite electricity sales
- Facilities with recently upgraded roofs or low redevelopment risk
Key benefits:
- Predictable lease payments over 15 to 25 years
- No capital required for system development or maintenance
- Enhances sustainability performance and overall asset value
Power Purchase Agreement (PPA): Fixed, Long-Term Energy Contract
A PPA enables a property to purchase the electricity generated on-site at a fixed, discounted rate—typically 15–60% below utility prices. Plankton develops, owns, and maintains the system, delivering long-term savings without operational burden.
Best suited for:
- Tenants or owner-operators responsible for electric utility costs
- Properties with large, stable energy loads
- Organizations with long-term occupancy expectations
Key benefits:
- No capital investment or maintenance responsibilities
- Fixed-rate energy pricing, hedging against future utility rate increases
- Long-term energy savings
Direct Purchase: Earning a Return Through Ownership
In a direct purchase, Plankton designs and installs a solar system, which is then sold to the property owner. The owner benefits directly from investment tax credits, accelerated depreciation, and long-term energy savings. Plankton provides ongoing operations and maintenance support.
Best suited for:
- Entities seeking to leverage tax incentives such as the ITC, MACRS, and state programs
- Properties seeking to increase long-term cash flow
- Portfolios with capital allocated for value-add infrastructure investments
Key benefits:
- 100% of energy savings and tax incentives accrue to the owner
- Typical payback periods of 3–7 years with available incentives
- Insulates properties from energy price volatility
Choosing the Right Financing Model
The optimal solar financing structure depends on several key factors:
- Cash flow objectives and capital availability
- Ownership structure and tax appetite
- Tenant lease arrangements (e.g., NNN, gross, master-metered)
- Planned hold period or disposition timeline
Plankton conducts a detailed assessment of each portfolio to identify the financing model that delivers the greatest net value. In many cases, a hybrid approach across multiple assets can optimize flexibility and returns.
