The SREC market is a state-regulated trading system where every megawatt-hour of electricity your solar panels produce becomes a Solar Renewable Energy Certificate you can sell to a utility. The certificate is separate from the electricity itself: you still use or sell the power, and the SREC represents the environmental attribute of having generated it from the sun. Utilities in states with solar mandates buy these certificates to prove compliance, and that demand is what puts money in your pocket. Earning it requires getting your system certified, registering with a regional tracking platform, choosing how to sell, and reporting the income correctly at tax time.
Why Utilities Pay for Your Solar Output
SREC markets exist because of state laws called Renewable Portfolio Standards. These laws require electric utilities to source a minimum percentage of their power from renewable energy by a set deadline.1U.S. Environmental Protection Agency. Energy and Environment Guide to Action – Chapter 5: Renewable Portfolio Standards Many of those standards include a solar carve-out, requiring that a specific slice of the renewable requirement come from solar generation. Utilities can meet the solar carve-out by building their own solar farms or by buying certificates from independent system owners. Buying from homeowners and businesses is usually cheaper.
One SREC is created for every 1,000 kilowatt-hours (one megawatt-hour) of solar electricity a certified system produces. A revenue-grade meter records the output and feeds the data to a regional registry, which prevents two parties from ever claiming the same megawatt-hour. That audit trail is what makes the market credible to regulators and buyers.
Which States Have an SREC Market
SREC programs only exist in states that have passed a solar carve-out. Active or legacy markets currently operate in New Jersey, Maryland, Pennsylvania, Ohio, Virginia, West Virginia, Indiana, North Carolina, Illinois, and the District of Columbia.2U.S. Environmental Protection Agency. State Solar Renewable Energy Certificate Markets Each state writes its own eligibility rules, and the structures vary. Massachusetts, once a major SREC state, transitioned to the Solar Massachusetts Renewable Target (SMART) program, though legacy SREC holders under the old system continue to earn credits at reduced incentive levels.
Eligibility depends on where your panels sit and which grid they feed. Some states also tie eligibility to interconnection date and close enrollment once capacity targets are hit. New Jersey’s successor program, SREC-II, uses a competitive solicitation process and has been extended through at least 2035. If SREC income is part of why you’re going solar, confirm your state’s program is open to new applicants before you sign an installation contract.
How SREC Prices Get Set
Every state with a solar carve-out charges utilities a penalty if they fall short of their solar requirement. That penalty, the Alternative Compliance Payment (or Solar Alternative Compliance Payment), is the effective ceiling on an SREC’s price. No utility will pay more for a certificate than it would pay in fines. SACP levels differ dramatically by state: the District of Columbia set its 2026 SACP at $440 per megawatt-hour, Maryland’s sits around $55, and Pennsylvania’s is roughly $74.3Lawrence Berkeley National Laboratory.

Market prices trade below the SACP, and the gap depends on supply and demand. When a state has more solar capacity than its annual carve-out requires, certificates pile up and prices drop. When solar development falls behind the mandate, prices climb toward the SACP. Pennsylvania has been heavily oversupplied, which has kept prices modest. The District of Columbia has the opposite problem: in-district solar struggles to keep pace with targets, so DC SRECs consistently trade among the highest-priced in the country.
Most states phase in higher solar requirements year by year, and the SACP often steps down on a parallel schedule. That means SREC revenue is almost never flat across the life of your system. Projecting your payback based on this year’s price alone will overstate what you actually collect.
Getting Certified and Registered
Two things have to happen before you can earn an SREC: state certification and a tracking system account. Neither is automatic when the panels switch on.
Certification runs through your state’s public utility commission or equivalent energy authority. The application covers nameplate capacity, interconnection date, equipment specifications, and proof the installer was qualified. Many installers file this paperwork as part of the job, but not all do. Ask upfront. Processing can take several weeks.
Your system also needs a revenue-grade meter that meets ANSI C12.20 accuracy standards.4National Electrical Manufacturers Association. ANSI C12.20-2015 – American National Standard for Electricity Meters Some states accept the utility’s own meter if it qualifies; others require a separate production meter. Settle this during installation, because retrofitting a meter later adds cost and delay.
Once the state certifies the system, you register it with the regional tracking platform that serves your area. The main platforms are PJM-GATS for the mid-Atlantic (including Pennsylvania, New Jersey, and Maryland), NEPOOL GIS for New England, and M-RETS for the Midwest.5NEPOOL GIS. Register NEPOOL Generator (MSS Project) The platform creates a digital account where SRECs accumulate as your meter reports production, and each certificate gets a unique serial number so it can be tracked from generation to retirement.
How to Actually Sell the Certificates
Most residential owners sell through aggregators or brokers rather than negotiating with utilities directly. These firms monitor your production, transfer certificates from your account to the buyer’s, and process payments. They take a percentage or a flat fee per certificate.
You generally choose among three sales structures:
- Spot market sales let you sell each certificate at the going price when it’s generated. Your flexibility is highest, and you capture any price spikes, but income swings from month to month and year to year.
- Long-term contracts lock in a fixed price per SREC for a set period, commonly five to fifteen years. The locked price is usually below current spot prices because the buyer is absorbing the risk that prices fall. You trade upside for predictability.
- Upfront payments give you a lump sum now for all the SRECs your system is expected to produce over a multi-year term. The per-certificate value is the lowest of the three because the buyer takes on both price risk and production risk. These contracts often include repayment clauses if you sell your home or the system underperforms, so read carefully.
Which structure fits depends on your situation. Spot sales work well in undersupplied markets like DC where prices have held up, but they’re a gamble in oversupplied markets where new installations can crater prices quickly. Long-term contracts tend to make sense when you financed the system and need predictable cash flow to cover loan payments.
Leased Panels Don’t Earn You SRECs
If you lease your panels or have a power purchase agreement with a third-party owner, you almost certainly do not own the SRECs. The system owner keeps the rights to all renewable energy certificates the panels produce. This is standard across the industry and is spelled out in most lease agreements. The leasing company may apply some of that value to lower your lease payment, but you will not receive separate SREC income. To earn SREC revenue, you need to own the system outright or through a loan.
SRECs Expire
A certificate is not a permanent asset. In most state markets, an SREC expires three years after it’s created. If you don’t sell it within that window, it becomes worthless. The expiration clock also interacts with the compliance calendar: utilities buy certificates to satisfy a specific energy year, so they prefer certificates that won’t expire before that compliance period closes. Sitting on SRECs hoping prices climb is a real risk, not a free option.
Entire state programs can also sunset. When a state hits its solar capacity target or shifts to a different incentive structure, the market for new SRECs may close. Existing holders usually keep earning under grandfathered terms, often at reduced values. That happened in Massachusetts and remains possible in any state nearing its targets.
Taxes on SREC Income
SREC payments are taxable. Aggregators or brokers who pay you $600 or more in a year are required to report those payments to the IRS, and you’ll typically get a Form 1099-MISC with the amount in Box 3 (Other Income) when the payments aren’t compensation for services.6Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC
For most residential owners, SREC income is reported as other income rather than self-employment income, so it generally doesn’t carry self-employment tax. If you own multiple systems or actively trade certificates as a business, the IRS may view it differently, which matters because self-employment tax adds roughly 15% on top of ordinary income tax. If your SREC income is substantial, talk to a tax professional familiar with renewable energy incentives.
SREC income is separate from the federal Residential Clean Energy Credit (the 30% solar credit). Receiving SREC payments does not disqualify you from that credit, but the IRS has indicated that certain state incentives can affect the cost basis used to calculate it. Keep records of every SREC transaction, including dates, amounts, and the energy year each certificate was generated in.
Selling Your Home
A home sale doesn’t automatically transfer SREC rights. You have to initiate a formal ownership transfer with your aggregator or broker and update your account with the regional tracking system. A real estate agent experienced with solar can help coordinate the handoff of warranties, maintenance agreements, and SREC registrations to the buyer.
Long-term and upfront contracts complicate the sale. Upfront contracts typically require you to repay the unearned portion of the lump sum if you sell before the term ends, and the repayment may exceed a simple pro-rata figure because it can include termination fees and the aggregator’s cost to replace the lost supply. Review any SREC contract obligations before you list, and factor potential repayment into your pricing.
