What Are SREC Solar Credits and How Do They Work?
By Team Faseeh Lall
Solar panels can create more financial value than electricity savings alone.
In certain markets, every eligible unit of solar electricity a system produces may also generate a tradable certificate known as a Solar Renewable Energy Certificate, or SREC.
These certificates can provide an additional revenue stream for qualifying homeowners and businesses. However, earning money from SRECs involves more than installing panels and waiting for a payment to appear.
The solar system may need to be certified, its production must be measured correctly, generation data must be submitted to an approved tracking system, certificates must be created, and the SRECs must then be sold or transferred.
This guide explains what SREC solar credits are, how they work, who buys them, what determines their value, and what solar owners should review before choosing an SREC broker or aggregator.
What Is an SREC Solar Credit?
An SREC is a type of Renewable Energy Certificate created specifically from solar electricity generation.
The U.S. Environmental Protection Agency defines a Renewable Energy Certificate as a market-based instrument representing the environmental and other non-power attributes of one megawatt-hour of renewable electricity delivered to the grid. One megawatt-hour equals 1,000 kilowatt-hours.
Therefore:
1 SREC generally represents 1,000 kWh of eligible solar electricity generation.
The electricity and the certificate are separate assets.
The physical electricity may be used by the property, credited through net metering, or delivered to the utility grid. The SREC represents the renewable attributes associated with that electricity.
Because the certificate can be separated from the electricity, it may be sold independently through an eligible SREC market.
Why Do SREC Markets Exist?
Some states and jurisdictions require electricity suppliers to obtain a percentage of the electricity they sell from renewable sources.
This requirement is commonly known as a Renewable Portfolio Standard, or RPS.
Certain programs include a separate solar requirement, often called a solar carve-out. Electricity suppliers can satisfy this requirement by purchasing and retiring eligible SRECs.
If a supplier does not obtain enough SRECs, it may have to pay a Solar Alternative Compliance Payment or another compliance charge, depending on the market.
This creates demand for SRECs produced by qualifying solar systems. Prices are influenced by the number of certificates available, the number suppliers need, program rules, and compliance costs.
How Do SREC Solar Credits Work?
Although requirements vary by market, the SREC lifecycle usually follows six main steps.
Step 1: A Solar System Produces Electricity
Solar panels convert sunlight into electricity.
A system’s electricity production is normally measured in kilowatt-hours. Once the system generates 1,000 kWh of eligible electricity, it may qualify to create one SREC.
A system that generates 8,000 kWh during a year could therefore create approximately eight SRECs, assuming all production is eligible and correctly reported.
Actual production depends on factors such as:
System size
Panel orientation
Shading
Weather
Equipment condition
Downtime
Soiling
System age
This means SREC income is connected directly to system performance. A system that produces less electricity may also generate fewer certificates.
Step 2: The System Is Certified for the Applicable Market
Installing solar panels does not automatically make a system eligible for every SREC market.
The owner may need to submit an application containing:
Property and ownership information
System capacity
Equipment details
Interconnection records
Permission-to-operate documentation
Meter information
Installation date
Photographs or technical documents
In Washington, D.C., eligible renewable generators must be certified through the Public Service Commission’s RPS program. Approved generators receive a certification number for participation in the program.
Eligibility rules differ by jurisdiction, so owners should confirm the applicable market before assuming their system can generate tradable SRECs.
Step 3: Solar Production Is Measured
The system’s electricity generation must be measured using an accepted method.
Depending on the market, generation may be reported through:
A revenue-grade production meter
An approved inverter
A monitoring platform
Manual meter readings
Automatic electronic reporting
Production estimates, where permitted
Washington, D.C.’s market requires revenue-grade metering and monthly production readings.
Accurate data matters because the number of certificates created depends on the eligible electricity recorded.
Missing readings, faulty meters, disconnected monitoring equipment, or incorrect data submissions can delay certificate creation.
Step 4: Generation Data Is Reported to a Tracking System
SRECs are created and tracked through regional certificate systems.
For systems located within the PJM region, the Generation Attribute Tracking System, commonly known as PJM GATS, records generator information, generation data, certificate creation, transfers, and retirement.
PJM GATS allows system owners or authorized representatives to report generation and manage certificates associated with qualifying renewable-energy systems.
A tracking system helps prevent the same renewable-energy attributes from being sold or claimed more than once.
Step 5: SRECs Are Created and Sold
Once enough eligible production has been recorded, certificates can be created in the tracking account.
The owner may then choose to:
Hold the SRECs
Sell them through the spot market
Enter a fixed-rate agreement
Transfer them to a broker
Authorize an aggregator to manage them
Sell them directly to an eligible buyer
SRECs may be purchased by electricity suppliers, utilities, brokers, aggregators, or other market participants.
A broker or aggregator may handle registration, production reporting, certificate tracking, sales, and payment administration on behalf of the system owner.
Step 6: The Buyer Retires the SREC
After purchasing an SREC, an electricity supplier may retire it to satisfy an RPS obligation.
Retirement removes the certificate from further circulation. It also prevents another party from using the same certificate for the same renewable-energy claim.
The EPA explains that tracking and retirement systems help ensure that each certificate has a unique owner and reduce the risk of double counting.
How Much Are SREC Solar Credits Worth?
There is no single national SREC price.
SREC values vary by:
State or jurisdiction
Market supply
Supplier demand
Solar carve-out requirements
Compliance-payment levels
Certificate age
Contract terms
Brokerage fees
Market expectations
An SREC price may rise when suppliers need more certificates than the market is producing. It may fall when certificate supply grows faster than demand.
Prices can also change substantially over time, which means historical prices should not be treated as guaranteed future values.
Washington, D.C. SREC Market Example
Washington, D.C. has historically maintained one of the strongest SREC markets in the Mid-Atlantic region.
According to the District’s 2026 Renewable Energy Portfolio Standard Report, electricity suppliers paid an average of approximately $407 per SREC for 2025 compliance, while District SRECs were trading around $370 in April 2026. The same report states that D.C. had 19,915 RPS-certified solar systems within the District at the end of 2025.
For energy year 2026, the District’s solar requirement is listed as 5%, and the Solar Alternative Compliance Payment is $440. The compliance payment can influence the market ceiling, but it does not guarantee that an individual SREC will sell for that amount.
Market prices can change, so solar owners should request current pricing and review the terms of any fixed-rate or spot-market offer before signing an agreement.
How Many SRECs Can a Solar System Generate?
A basic estimate can be calculated using annual electricity production:
Estimated SRECs = Annual eligible solar production in kWh ÷ 1,000
For example:
5,000 kWh may create approximately 5 SRECs
8,500 kWh may create approximately 8 full SRECs, with remaining production carried according to tracking-system rules
12,000 kWh may create approximately 12 SRECs
This estimate is based on electricity production, not simply the number of panels installed.
Two systems with the same rated capacity may generate different numbers of SRECs because of shading, orientation, weather, maintenance, inverter performance, and downtime.
Are SRECs the Same as Net Metering Credits?
No.
Net metering credits relate to electricity exported to the utility grid. They usually appear on the customer’s electricity account and may reduce the amount owed to the utility.
SRECs represent the renewable attributes of eligible solar electricity. They are created and sold separately through certificate markets.
A solar owner may potentially receive electricity savings, net-metering credits, and SREC revenue from the same system, depending on local rules and ownership arrangements.
Who Owns the SRECs?
SREC ownership depends on the system’s purchase agreement, financing documents, lease, power purchase agreement, and local program rules.
The homeowner may not own the certificates when:
The system is leased
A third party owns the panels
A power purchase agreement assigns the SRECs to the provider
The installation contract transferred certificate rights
A previous brokerage agreement remains active
Owners should review the original solar agreement before registering or attempting to sell certificates.
The EPA also explains that when an owner sells the RECs associated with an on-site solar system, the owner gives up the right to claim the renewable attributes represented by those certificates. The system may still produce solar electricity, but the exclusive renewable-energy claim belongs to the certificate owner.
SREC Broker vs SREC Aggregator
The terms are sometimes used interchangeably, but the service structures can differ.
An SREC broker generally helps connect certificate owners with buyers and arranges transactions.
An SREC aggregator may combine certificates from multiple smaller systems and manage activities such as:
Market registration
Production reporting
Certificate tracking
Certificate sales
Payment distribution
Account administration
Before selecting a provider, ask:
Who owns the certificates?
What brokerage or management fees apply?
Is the price fixed or market-based?
How long is the agreement?
When are payments issued?
Who reports production?
What happens if monitoring fails?
Can the owner cancel or transfer the account?
What happens when the property is sold?
Are maintenance and monitoring services included?
A provider should explain these terms in writing. “We handle everything” is a pleasant phrase, but contracts have an irritating habit of requiring actual details.
Common SREC Problems Solar Owners Should Avoid
SREC revenue can be delayed or reduced by administrative and technical issues.
Common problems include:
Failing to certify the system
Missing monthly meter readings
Incorrect generation submissions
Faulty production meters
Monitoring disconnections
Unresolved inverter failures
Unclear certificate ownership
Expired brokerage agreements
Incomplete property-transfer records
Selling under unclear fee structures
Production monitoring is especially important because technical problems affect potential certificate volume.
An inverter fault that remains unresolved for several months may reduce both electricity savings and the number of SRECs the system can create.
How Solar Asset Management Supports SREC Revenue
SREC brokerage and solar asset management address different but connected parts of solar ownership.
Brokerage manages the certificates. Asset management helps protect the system producing them.
A coordinated service may include:
Proactive system monitoring
Production verification
Meter-data review
Certificate tracking
Maintenance coordination
Installer communication
Warranty support
Issue resolution
SREC sales and payment reporting
SAMS combines SREC brokerage with solar asset management for Washington, D.C. homeowners. Its services include monitoring, production tracking, maintenance coordination, and certificate management.
This combined approach can help owners avoid the familiar arrangement where one company tracks the certificates, another watches the system, and everybody assumes a third person is handling the actual problem.
Final Thoughts
SREC solar credits allow qualifying solar owners to earn value from the renewable attributes of the electricity their systems produce.
The process generally involves:
Generating eligible solar electricity
Certifying the system
Measuring production
Reporting generation
Creating certificates
Selling or transferring SRECs
Retiring the certificates for compliance or another eligible purpose
The concept is straightforward, but registration, metering, ownership, reporting, pricing, and contract terms require careful attention.
SAMS helps Washington, D.C. solar owners register, track, manage, and sell SRECs while supporting the technical performance of the systems generating them.
A well-managed SREC program should do more than sell certificates. It should provide clear ownership terms, accurate production reporting, transparent payments, and reliable support when the solar system stops performing as expected.
Frequently Asked Questions
What does SREC stand for?
SREC stands for Solar Renewable Energy Certificate. It represents the renewable attributes associated with one megawatt-hour, or 1,000 kilowatt-hours, of eligible solar electricity generation.
How does a solar system earn SREC credits?
An eligible system earns SRECs by generating solar electricity, recording production through an accepted meter or monitoring method, and reporting the generation to the applicable certificate-tracking system.
Can every solar system generate SRECs?
No. SREC eligibility depends on the system’s location, certification, ownership, installation date, meter requirements, and applicable market rules.
How much is one SREC worth?
The value of an SREC depends on the specific market, certificate supply, supplier demand, compliance requirements, contract terms, and brokerage fees. Prices change over time and are not guaranteed.
Can I sell SRECs and still receive net-metering credits?
Potentially, yes. Net-metering credits apply to exported electricity, while SRECs represent renewable-energy attributes. Eligibility and ownership depend on local rules and the system agreement.
Can I sell SRECs without a broker?
Some owners can manage registration, production reporting, certificate transfers, and sales directly. However, a broker or aggregator may reduce the administrative work and provide access to different sale arrangements.
What happens to SRECs when a solar home is sold?
Certificate ownership after a property sale depends on the purchase agreement, existing brokerage contract, market rules, and transfer documentation. Buyers and sellers should address SREC rights during the property transaction.
