Estimated reading time: 6 minutes
At a Glance
- Site-ready solar projects contracted in 2026 may still qualify for the 30% federal tax credit if operational by December 31, 2027.
- Expanding building-performance requirements are increasing the financial cost of delaying energy and emissions improvements.
- Direct ownership, site leases, and portfolio-level strategies give owners multiple ways to create value, depending on timing, capital, and property readiness.
Introduction
Commercial building owners are navigating a dynamic and fast-changing energy landscape shaped by increasing electricity demand, rising electricity costs, and compliance obligations under new and expanding building electrification ordinances. Distributed solar is the lowest-cost and fastest technology to deploy to meet this moment. However, changes to federal tax incentives and project qualification deadlines are making the timing and structure of solar projects increasingly important.
Building owners now must consider not only whether a property is suitable for solar, but also how quickly a project can be developed, and whether direct ownership, a lease structure or a combination of approaches will deliver the greatest long-term value for each property and at the portfolio level.
This market update covers the federal incentive deadline, the compliance costs building performance ordinances can create, the ownership and financing structures available, and how to choose a partner who can execute within the prescribed timelines.
The Window for the Federal Tax Credit Is Narrowing
The 30% Investment Tax Credit (ITC) remains available for qualifying projects and accelerated bonus depreciation continues to provide significant tax benefits available for new projects.
What’s changed is the ITC timeline. The construction-start deadline that allowed projects to lock in a longer completion window has passed. Systems starting construction now must be placed in service by December 31, 2027, to qualify for the ITC — roughly a year and a half to be fully installed, interconnected, and generating power. That’s workable for most properties if contracted in 2026, but there’s little room for delays in permitting, utility interconnection, procurement, or construction.
For many properties contracted in 2026, completing the project in time to qualify for the ITC remains feasible, provided the property is ready for a 2027 installation and sufficient utility interconnection capacity is available.
Owners and developers who evaluate properties now will have more flexibility and time to compare ownership and financing structures, coordinate solar with capital improvement plans or roof replacement projects, and align the project installation schedule at the chosen properties. While the fundamentals of solar look good with and without the ITC, projects that monetize 30% of the project cost will have superior financial returns.
Building Performance Requirements Raise the Stakes
The ITC is not the only clock running. State and local building codes, emissions reduction targets, and corporate sustainability commitments are creating new performance standards and financial obligations for commercial building owners. Although many policies include transition periods, owners must begin planning and implementing improvements early enough to meet increasingly stringent requirements.
In Massachusetts, policies such as BERDO in Boston, BEUDO in Cambridge, and Large Building Energy Reporting (LBER) are encouraging owners to reduce emissions and improve building performance. Similar policies are emerging throughout the Northeast.
For many owners, these policies have moved beyond reporting requirements and now include real fees for non-compliance. Buildings in Boston that exceed their BERDO emissions limits face Alternative Compliance Payments of $234 per metric ton of CO₂e plus $1,000 per day for every day of non-compliance. Onsite solar can directly offset that exposure. Eligible Massachusetts Class I Renewable Energy Certificates from qualifying onsite or offsite renewable energy resources may also be used to support BERDO compliance, subject to applicable program requirements.
Potential Compliance Costs Avoided with Onsite Solar
While this example is specific to Boston, it illustrates how building performance policies can have measurable financial implications. Actual solar production, emissions reductions, and avoided compliance costs will vary based on building energy use, system design, applicable emissions limits, and reporting requirements.
Choosing the Right Solar Ownership and Financing Approach
Large rooftops, parking lots, and land can host solar installations that generate near-term and long-term financial returns. However, there is no single ownership structure that is right for every commercial property. The right approach depends on timing, site readiness, who pays the electric bill, available capital, ownership objectives, and the property’s role in the broader portfolio. For some properties, direct ownership may produce the strongest financial returns. For others, a site lease may better align with the owner’s capital priorities, timeline, or property strategy.
Direct Ownership
Direct Ownership – Behind-the-Meter
Where the building owner pays the electric bill, installing the system behind-the-meter may offer the greatest value. Powering the building with onsite solar reduces the amount of electricity purchased from the utility and limits exposure to volatile and rising grid-delivered electricity costs. Depending on the project and jurisdiction, additional value may come from state incentives, federal tax benefits and depreciation, and reduced building-performance compliance costs.
Direct Ownership – Front-of-the-Meter
A building owner may prefer to invest in a system that sends electricity directly to the grid. Rather than offsetting the building’s electric use, the project generates revenue through a 20-year tariff agreement with the utility. This is a highly predictable and bankable income stream backed by an investment-grade counterparty.
Allocating Credits Across a Portfolio
Depending on the applicable state program and utility rules, a project may be able to direct bill credits to other eligible properties. This can be particularly valuable for owners seeking to offset high electricity costs or reduce emissions exposure at buildings subject to requirements such as BERDO.
Solar Site Leases
For owners that do not want to invest capital, cannot use the available tax benefits, or cannot complete a purchased project by the end of 2027, a rooftop solar site lease may be the strongest option. The developer finances and maintains the projects and pays rent to the building owner. Depending on the configuration and the applicable solar program, the project may also contribute to building-performance compliance.
In preparation for the ITC safe harbor deadline, Solect invested in more than 100 MW of solar equipment intended to support future projects. Because Solect can finance and own site-lease and power-purchase-agreement projects, ITC-eligible equipment and federal tax benefits can be incorporated into project economics, potentially supporting more competitive lease payments or energy pricing.
Case Study: Direct Ownership and Site Leases Within the Same Portfolio — Parsons Commercial Group
Solect’s relationship with Parsons Commercial began in 2015, when Parsons, Solect’s landlord at its Hopkinton, MA operations center, became interested in how solar could add value across its properties. Parsons’ initial projects were installed at Solect’s building and two others. Since then, through new acquisitions and property sales, Solect has continued developing projects at Parsons properties. As of 2026, twenty-two projects are complete, split nearly 50/50 between direct ownership and Solect-financed site leases. Ongoing monitoring and asset management have supported strong system performance and strong financial returns.
Choosing the Right Partner
As project timing and structure become more important, commercial real estate owners need a solar partner that can support more than a single transaction or installation. The right partner should be able to evaluate opportunities across a portfolio, recommend the structure that best aligns with each property, and carry projects from initial feasibility and financing through design, construction, commissioning, and long-term asset management.
That requires financial strength, policy and market expertise, in-house design and engineering resources, proven installation capabilities, and a strong record of operating and maintaining solar assets over time — along with financing flexibility, since some owners will choose to purchase and own their systems while others prefer a third-party-owned structure with no upfront capital required.
Since 2009, Solect Energy has served businesses and commercial building owners throughout Massachusetts and New England, growing into one of the largest commercial solar developers in the Northeast. Solect develops and delivers projects under both direct-ownership and third-party-owned site lease structures and is equally equipped to support either approach as demonstrated in the Parsons partnership above.
As a Pattern Energy company, Solect also brings the financial resources and long-term perspective to support owners as individual properties become solar-ready over time. That long-term perspective is increasingly important: not every property in a portfolio will be ready for solar at the same time, and compliance obligations will keep increasing. Solect is positioned to work with owners year after year — developing projects as roofs, capital plans, interconnection opportunities, and property strategies align, and carrying them through installation and decades of operation.
Evaluate Now to Preserve Your Options
The federal ITC deadline and expanding building performance requirements are converging on the same timeline, making it increasingly important to evaluate properties now. For site-ready properties, direct ownership may allow owners to capture the federal tax benefits while they remain available. For other properties, a site lease can incorporate federal incentive value into the project economics without requiring the owner to make the investment. Owners who begin evaluating their portfolios today will retain greater flexibility to compare structures, align projects with capital plans, and capture the strongest available financial benefits.
