Solar renewable energy credits (SRECs) are tradable certificates that represent the environmental value of electricity generated from solar energy systems.

SRECs allow utilities and other entities to meet renewable energy requirements by purchasing credits tied to solar generation. According to the U.S. Environmental Protection Agency, renewable energy certificates track and verify the production of renewable electricity and its environmental attributes¹.

How SRECs work

SRECs are generated when a solar system produces electricity and can be sold in certain markets.

Typical process:

• A solar system generates electricity

• Production is measured and verified

• SRECs are issued based on energy output (usually 1 per MWh)

• Credits can be sold to utilities or other buyers

Utilities purchase SRECs to comply with state renewable portfolio standards, which require a portion of electricity to come from renewable sources.

Where SRECs are available

SREC programs are not available everywhere and depend on state policies.

• Some states have established SREC markets

• Others use alternative incentive structures

• Program rules, pricing, and eligibility vary by location

The U.S. Energy Information Administration notes that renewable energy policies, including credit systems, are typically set at the state level and vary widely across the U.S.²

Why SRECs matter

SRECs play an important role in supporting solar energy adoption.

They help:

• Create financial incentives for solar generation

• Support state renewable energy goals

• Encourage investment in solar energy systems

• Provide a mechanism for tracking renewable energy production

The Solar Energy Industries Association identifies SRECs as one of several policy tools used to expand solar deployment in certain markets³.

How SRECs relate to solar plans and ownership

Eligibility for SRECs depends on system ownership and program rules.

• In some cases, homeowners who own their system may be able to earn and sell SRECs

• In other cases, the system owner (such as a third-party provider) retains the credits

• Participation depends on state programs and contract terms

SRECs vs. renewable energy certificates (RECs)

SRECs are a specific type of renewable energy certificate.

• REC: represents renewable energy from any source (solar, wind, hydro)

• SREC: specifically represents solar-generated electricity

Both are used to track and verify renewable energy production, but SRECs are limited to solar energy systems.

Takeaways

• SRECs represent the environmental value of solar electricity generation

• One SREC is typically issued per megawatt-hour of solar energy produced

• SRECs can be sold in certain state markets

• Availability and value vary by location and policy

• Ownership of SRECs depends on system ownership and contract terms
