Quick answer: what an SREC is (in one minute)
An SREC (Solar Renewable Energy Credit) is a certificate that represents the “renewable attribute” of solar electricity your system generates. In plain terms:
- 1 SREC = 1 megawatt-hour (MWh) = 1,000 kilowatt-hours (kWh) of solar electricity generated.
- You may be able to sell SRECs separately from the electricity itself, depending on your state’s program.
This “1 MWh certificate” idea is the core of renewable energy certificates (RECs) in general: a REC is issued when one MWh is generated and delivered to the grid, and it represents the non-power “renewable” attributes. Source: U.S. EPA definition of RECs. (Source: https://www.epa.gov/green-power-markets/renewable-energy-certificates-recs)
USA-safe note: SREC rules vary by state, utility territory, and program year. Treat this as homeowner education—not financial, legal, or tax advice.
SREC vs REC vs net metering credits: don’t mix these up
REC (renewable energy certificate): the broad category
A REC is the umbrella term. It’s a market-based instrument representing the attributes of renewable electricity generation, typically issued in 1 MWh increments. Source: U.S. EPA. (Source: https://www.epa.gov/green-power-markets/renewable-energy-certificates-recs)
SREC: a REC specifically for solar in certain compliance markets
An SREC is a REC created from solar generation in states that created solar or distributed generation requirements (often called a “solar carve-out”). A homeowner-friendly way to think of it:
- Your utility bill credits (net metering / net billing) relate to energy and money flows on your bill.
- SRECs relate to the renewable attribute certificate created by your solar production.
Many homeowner groups explain it this way: you earn one SREC per 1,000 kWh generated, and it can be sold separately from the physical electricity. Source: Solar United Neighbors. (Source: https://solarunitedneighbors.org/resources/solar-renewable-energy-credits-srecs/)
Net metering / net billing credits: bill credits, not certificates
Net metering or net billing determines how your exported kWh is credited on your utility bill. If you want a simple explanation of imports/exports and why exported energy can be worth less than imported energy, read:
Do you qualify to earn SRECs? (5 quick checks)
Eligibility is program-specific, but most homeowners can screen themselves quickly with these checks.
Check 1: Does your state have an SREC market or solar REC program?
Not every state has an SREC market. A reliable starting place is:
- EPA’s overview of state SREC markets (good map-level context). (Source: https://www.epa.gov/greenpower/state-solar-renewable-energy-certificate-markets)
- DSIRE (Database of State Incentives for Renewables & Efficiency) for state-by-state program details and updates. (Source: https://programs.dsireusa.org/)
Homeowner rule: If you can’t confirm your state/utility has a solar REC/SREC pathway, assume you may not have one until proven otherwise.
Check 2: Do you own the system (and the SRECs)?
This is one of the biggest “gotchas.” If you sign a lease or PPA, the company may own the system—and may also keep the SRECs.
Before you sign anything, read:
What to look for in contracts: A line stating who owns “RECs,” “SRECs,” “environmental attributes,” or “renewable energy credits.” If it’s not explicit, ask.
Check 3: Can your production be verified (metering/monitoring requirements)?
Programs typically require verified production data. That might come from:
- a revenue-grade meter,
- utility-grade production reporting,
- or approved inverter monitoring depending on the program rules.
This is why “how your system reports production” matters. To understand the production numbers you’ll be using, read:
Check 4: Is your system registered in the right tracking system?
SRECs are typically created/issued inside tracking systems that record generation attributes for a region. For example:
- PJM-GATS is widely used in parts of the Mid-Atlantic region. (Source: https://www.pjm-eis.com/-/media/DotCom/pjm-eis/documents/gats-operating-rules.pdf)
- NEPOOL GIS is a tracking system used in New England’s power pool context. (Source: https://nepoolgis.com/)
Some state agencies explicitly tell solar owners they can participate directly or via an aggregator in the relevant system (example guidance in Massachusetts points to NEPOOL GIS participation/aggregation). (Source: https://www.masscec.com/solar-renewable-energy-certificate-srec)
Check 5: Are you already “giving them away” in your solar quote?
Some installers or finance offers include SREC handling, but the tradeoff might be:
- they keep the SREC revenue,
- or they charge an admin fee,
- or they lock you into a low fixed price per credit.
This is why SRECs belong in your quote comparison checklist. Start here:
How you earn SRECs: the simple step-by-step
Think of SRECs as a 4-step pipeline:
- Your panels generate electricity (kWh).
- That generation is measured/verified under program rules.
- A tracking system issues certificates in 1 MWh increments.
- You sell/transfer those certificates to a buyer (often a utility or supplier for compliance).
Step 1: estimate how many SRECs you could earn (quick math)
You earn roughly:
- SRECs per year ≈ annual solar production (kWh) ÷ 1,000
Example: If your system produces 9,500 kWh/year, that’s about 9.5 SRECs/year (some programs handle fractions differently—always follow program rules).
If you want a planning estimate of annual production, use:
Step 2: register the system (or authorize an aggregator to do it)
Many homeowners use an aggregator or broker service that registers the system, submits production, and sells the credits for a fee or revenue share. In some regions, SREC help centers describe “minting” and transferring credits via PJM-GATS as part of the incentive process. (Source: https://srechelp.carbonsolutionsgroup.com/hc/en-us/articles/16980522945684-PJM-GATS-Pennsylvania-Jersey-Maryland-Generation-Attribute-Tracking-System)
Step 3: production reporting and certificate issuance
Tracking systems exist to issue and track certificates representing MWh of generation for a region. For example, NEPOOL GIS describes itself as issuing and tracking certificates for MWh of generation and load within its control area. (Source: https://nepoolgis.com/)
Step 4: sell or transfer SRECs to a buyer
SRECs can be sold through aggregators, brokers/marketplaces, or program-specific channels. In PJM regions, guidance often explains that SRECs can be transferred to a buyer’s account inside the tracking system. (Source: https://srecdelaware.com/instructions-for-srec-transfer-in-pjm-gats/)
How to sell SRECs (3 common paths)
The “best” path depends on how hands-on you want to be.
Path A: Use an aggregator (most beginner-friendly)
Best for: homeowners who want simplicity.
Typical tradeoff: fees or a share of SREC revenue.
Some state resources explicitly mention aggregation as a simpler option for many owners (example: guidance describing aggregation and marketing of credits). (Source: https://www.masscec.com/solar-renewable-energy-certificate-srec)
Path B: Use a broker/marketplace (more control, more work)
Best for: homeowners who want to compare offers and understand pricing.
Typical tradeoff: you manage more steps and paperwork.
Path C: Program/utility-administered approach (where available)
Best for: states where the program structure provides a clearer “submit → get paid” pathway.
Important: program rules can change. DSIRE entries sometimes note major legislative or program changes and deadlines. Use DSIRE as your “current rules” directory. (Source: https://programs.dsireusa.org/)
What are SRECs worth? (what actually moves the price)
SREC pricing is not like a fixed rebate. It can vary based on:
- state policy design (compliance requirements, solar carve-outs, program caps),
- supply and demand (how much solar is generating vs how many credits are needed),
- penalty/alternative compliance payment concepts that can act like a “ceiling” in some markets,
- contract structure (spot sales vs longer-term contracts),
- fees (aggregation, brokerage, registration).
If you want a credible “where do I check my state?” approach, EPA points to DSIRE for state-specific details on RPS solar provisions and SREC programs. (Source: https://www.epa.gov/greenpower/state-solar-renewable-energy-certificate-markets)
How SRECs affect solar payback (simple, realistic examples)
SRECs can improve payback, but only if:
- you’re eligible in your state/program,
- you actually keep ownership of the SRECs,
- fees don’t eat most of the value,
- and your export credit structure still supports savings.
Example 1: modest SREC value
Assume:
- Annual production: 9,000 kWh/year → ~9 SRECs/year
- SREC net value after fees: $35 each (example only)
Annual SREC revenue ≈ 9 × $35 = $315/year.
If your system cost is $20,000, an extra $315/year might reduce payback by roughly a year or less depending on your bill savings and financing.
Example 2: higher SREC value (where programs are stronger)
Assume:
- Annual production: 11,000 kWh/year → ~11 SRECs/year
- SREC net value after fees: $150 each (example only)
Annual SREC revenue ≈ 11 × $150 = $1,650/year.
That can materially change payback—especially in areas where exported kWh is credited poorly under net billing. To understand export value, read:
Reality check: SREC prices and program rules change. Never base a solar purchase on an SREC value you can’t verify in writing.
Table(s)
| Item | Net metering / net billing | SRECs |
|---|---|---|
| What it is | How your exported kWh is credited on your utility bill | A certificate for the “renewable attribute” of your solar generation |
| Unit | kWh and dollars on your bill | 1 SREC = 1 MWh = 1,000 kWh of solar generation (Source: EPA REC definition + common SREC explanation) |
| Where it shows up | Utility bill credits/charges | Tracking system account (e.g., regional certificate registry) |
| Who pays | Your utility billing mechanism | Often a buyer needing compliance credits (varies by program) |
| Big homeowner risk | Export credits may be worth less under net billing | You may sign away SREC ownership in a lease/PPA or contract |
Safety checklist: 10 common SREC mistakes (and how to avoid them)
- Assuming every state has SRECs. Verify with EPA + DSIRE first. (Source: https://www.epa.gov/greenpower/state-solar-renewable-energy-certificate-markets)
- Not confirming SREC ownership in your contract. Look for “RECs/SRECs/environmental attributes.”
- Mixing up bill credits with SRECs. They are separate value streams.
- Letting “SREC revenue” sell you a system. Only count what you can verify and keep.
- Ignoring fees. Ask aggregators for a clear fee schedule and net payout estimate.
- Not understanding production reporting requirements. Confirm what metering/monitoring is accepted.
- Not saving documentation. Keep registration confirmations, production reports, and sale statements.
- Assuming long-term pricing. Markets can change based on policy and supply/demand.
- Waiting too long to register. Some programs have deadlines or vintage/eligibility windows.
- Not asking about taxes. SREC income may have tax implications; get professional guidance.
Taxes & paperwork: homeowner-safe guidance (not tax advice)
Homeowners frequently ask: “Is SREC income taxable?”
In practice, many industry resources say SREC income is likely taxable, but also note that the issue can be complex and not always clearly documented in one definitive IRS statement for every situation. (Source: Aurora Solar notes complexity and lack of clear IRS documentation.) (Source: https://aurorasolar.com/home-solar/blog/solar-101/srecs)
Safe approach: Keep clean records of:
- SREC statements (quantity, sale price, fees)
- Any forms you receive (some services issue tax forms depending on payouts and structure)
- Installer contract language on ownership
Also note: The IRS has specific guidance that utility payments/credits for selling electricity back to the grid (like net metering credits) don’t affect qualified expenses for the Residential Clean Energy Credit calculation. That’s a separate topic, but it’s useful to understand the IRS distinguishes bill credits from credit eligibility calculations. (Source: IRS Residential Clean Energy Credit page.)

FAQ (5–8)
1) What is an SREC in simple terms?
An SREC is a certificate created from your solar production. You typically earn 1 SREC per 1,000 kWh (1 MWh) generated, and you may be able to sell it in certain state programs. (Source: EPA REC definition; Solar United Neighbors SREC explanation.)
2) Do I get SRECs automatically when I install solar?
Usually no. Many programs require registration, verified production reporting, and use of an approved tracking system or aggregator.
3) Which states have SRECs?
It changes over time. Start with EPA’s state SREC markets overview and confirm details in DSIRE for your specific state/program. (Source: https://www.epa.gov/greenpower/state-solar-renewable-energy-certificate-markets)
4) Can I sell SRECs if I have a lease or PPA?
Often the third-party owner keeps the SRECs, but it depends on the contract. Verify “RECs/SRECs/environmental attributes” language before signing. See: Solar Loan vs Lease vs PPA.
5) How many SRECs will my system produce?
Roughly annual solar kWh ÷ 1,000. To estimate annual kWh, use PVWatts: PVWatts step-by-step guide.
6) Do SRECs change my net metering credits?
No. Net metering/net billing affects your utility bill credits for exported energy; SRECs are separate certificates. See: Net Metering Explained.
7) Is SREC income taxable?
Many sources say it is likely taxable, but guidance can be complex. Treat it as a “talk to a tax pro” topic and keep excellent records. (Source: https://aurorasolar.com/home-solar/blog/solar-101/srecs)
8) What should I ask my installer about SRECs?
- “Who owns the SRECs/environmental attributes?”
- “Will you register my system for SRECs? What are the fees?”
- “What production verification method is used?”
- “Can I opt out and use my own aggregator?”
