Solar tax equity allows qualified investors to participate in eligible solar projects while receiving a combination of potential tax benefits and project cash flow. The strategy can be attractive, but it is not appropriate for every investor. Eligibility depends on the investor’s tax profile, the character of the investor’s income, the structure of the transaction, and the investor’s ability to accept project and tax risk.
This guide explains the characteristics commonly associated with a solar tax equity investor and the questions that should be reviewed with qualified tax, legal, and investment professionals.
What Is a Solar Tax Equity Investor?
A solar tax equity investor provides capital to an eligible solar project or portfolio in exchange for an agreed share of the project’s potential tax credits, deductions, cash distributions, and other economic benefits.
The investment is commonly structured through a partnership or limited liability company. The project sponsor manages the development and operation of the solar assets, while the tax equity investor receives benefits according to the governing agreements.
These transactions are more complex than purchasing a publicly traded stock or bond. Investors must evaluate both the underlying solar assets and the tax rules governing the anticipated benefits.
Who May Be a Suitable Solar Tax Equity Investor?
Potential investors may include corporations, family offices, trusts, partnerships, and qualified individuals. Suitability depends on the investor’s complete financial and tax situation.
A prospective investor should generally consider the following factors:
- Sufficient federal tax liability to potentially use the available tax credits
- The proper type of income against which credits and deductions may be applied
- Available capital that can remain committed for the required investment period
- Comfort with an investment that may have limited liquidity
- The ability to evaluate project, sponsor, operational, and compliance risks
- Access to experienced tax, legal, and financial advisors
Why the Character of Income Matters
Individual investors may face passive activity limitations. These rules can restrict how credits and losses from a passive investment are used. An investor with substantial tax liability does not automatically qualify to use every available solar tax benefit.
The Internal Revenue Service provides specific rules for passive activity credits, at risk limitations, business credits, and the treatment of different taxpayer types. Investors should review these rules with their tax advisor before committing capital.
Corporations may have different considerations, but they must still evaluate credit limitations, tax capacity, ownership structure, project eligibility, and reporting requirements.
How Solar Tax Equity Returns May Be Generated
A solar tax equity investment may produce value through several sources:
- Eligible federal energy tax credits
- Potential depreciation deductions
- Cash distributions generated by project operations
- A potential payment when the investor’s ownership interest is transferred or purchased
The timing and availability of these benefits depend on the transaction documents, project performance, applicable tax law, and the investor’s individual circumstances. Projected benefits are not guaranteed.
Understanding the Partnership Flip Structure
Many solar tax equity transactions use a partnership flip structure. During the initial period, the tax equity investor may receive a larger allocation of tax benefits and certain economic returns. After agreed conditions are satisfied, the allocation may change, or flip, so the project sponsor receives a larger share.
The structure must be carefully documented and administered. Investors should understand allocation provisions, target returns, cash distribution priorities, purchase options, reporting duties, and the events that could change the expected outcome.
Important Risks to Review
Solar tax equity investments involve meaningful risks. These may include:
- Changes in tax law or regulatory guidance
- Failure of a project to satisfy eligibility requirements
- Incorrect calculation of eligible project basis
- Recapture of previously claimed tax credits
- Construction delays or operational problems
- Lower than projected electricity production or revenue
- Counterparty and sponsor risk
- Limited ability to sell or exit the investment early
- Legal, accounting, and administrative complexity
Federal energy credit recapture rules can apply when certain events occur during the applicable recapture period. Proper project monitoring, documentation, insurance, and transaction management are therefore important parts of due diligence.
Questions Prospective Investors Should Ask
Before evaluating a specific opportunity, an investor should ask:
- How much eligible tax liability do I expect to have?
- Do passive activity limitations apply to my situation?
- What credits and deductions are expected from the investment?
- How was the eligible project basis calculated?
- Who developed, owns, operates, and maintains the solar assets?
- What assumptions support the projected cash flow?
- What could trigger tax credit recapture?
- How long will my capital remain committed?
- What reporting will I receive?
- What are the expected legal, tax, and administrative costs?
Is Solar Tax Equity Right for You?
A qualified solar tax equity investor needs more than available capital. The investor should have an appropriate tax profile, a clear understanding of the transaction, sufficient professional support, and the ability to accept the investment’s risks and holding period.
