Key Takeaways
- One SREC equals 1 MWh (1,000 kWh) of solar electricity generated
- SRECs trade on open markets — prices range from under $10 to over $400 depending on the state
- Only available in states with Solar Renewable Portfolio Standards (RPS) solar carve-outs
- Revenue from SRECs is separate from net metering credits or electricity savings
- SREC income can reduce payback periods by 1–4 years in strong markets
- Prices are volatile and policy-dependent — long-term contracts reduce risk
What Is an SREC?
An SREC (Solar Renewable Energy Certificate) is a market-based instrument that represents the environmental attributes of 1 megawatt-hour (MWh) of solar electricity generation. When a solar system produces 1,000 kWh, the owner earns one SREC, which can be sold separately from the electricity itself.
SRECs exist because of state-level Renewable Portfolio Standards (RPS) that require utilities to source a percentage of their electricity from solar. Utilities that cannot generate enough solar power on their own must purchase SRECs from solar system owners to demonstrate compliance. This creates a market where solar owners earn revenue simply by generating clean energy.
SRECs are one of the most misunderstood incentives in residential solar. They represent real, tradeable income on top of electricity savings — but only in states that mandate them. Solar professionals must know which markets qualify and what current prices look like.
How SRECs Work
Solar System Generates Electricity
The PV system produces electricity measured by a production meter or utility-grade monitoring. Every 1,000 kWh generated creates one SREC.
SREC Is Registered
The system owner registers with a state tracking platform (e.g., PJM-GATS, NEPOOL GIS). Production data is reported monthly, and SRECs are issued to the owner’s account.
SREC Is Sold on the Market
Owners sell SRECs through brokers, aggregators, or spot markets. Buyers are typically utilities needing to meet their solar RPS obligations.
Utility Retires the SREC
The purchasing utility “retires” the SREC to count it toward their renewable energy compliance. Each SREC can only be retired once.
Annual SREC Revenue = (Annual Production in kWh ÷ 1,000) × SREC Price per CertificateSREC Markets by State
SREC availability and pricing vary dramatically. Only states with solar carve-outs in their RPS create meaningful SREC markets.
| State | Approximate SREC Price (2025–2026) | Market Status | Notes |
|---|---|---|---|
| New Jersey | $180–$230 | Active, strong | Transitioned to TREC program; prices stabilized |
| Massachusetts | $250–$350 | Active, strong | SMART program replaced SRECs for new systems |
| Maryland | $50–$80 | Active, moderate | Prices declined as supply increased |
| Pennsylvania | $5–$15 | Active, weak | Oversupplied market, low solar carve-out |
| Washington DC | $300–$420 | Active, strong | Small market, high demand, limited supply |
| Ohio | $5–$10 | Active, weak | Reduced RPS targets lowered demand |
| Illinois | Varies | Transitioning | Adjustable Block Program replacing open market |
SREC prices are volatile. In 2010, New Jersey SRECs traded above $600. By 2015, they had fallen below $200. Always model financial projections with conservative SREC assumptions, and show customers the system’s ROI both with and without SREC income.
SRECs vs. RECs
SRECs are a subset of the broader Renewable Energy Certificate (REC) market, with one key difference.
SREC
Represents 1 MWh of specifically solar generation. Only traded in states with solar carve-outs. Prices are typically much higher than generic RECs because supply is limited to solar producers.
REC
Represents 1 MWh from any qualifying renewable source (wind, hydro, biomass, solar). Traded nationally. Prices are much lower ($1–$5) because supply is larger and includes cheaper generation sources.
Impact on Solar Financial Modeling
SRECs can represent a significant portion of a solar system’s total financial return. Accurate SREC modeling is a core function of the generation and financial tool in professional solar software.
| System Size | Annual Production | SRECs/Year | Revenue at $200/SREC | Revenue at $50/SREC |
|---|---|---|---|---|
| 6 kWp | 8,400 kWh | 8.4 | $1,680 | $420 |
| 10 kWp | 14,000 kWh | 14 | $2,800 | $700 |
| 100 kWp | 140,000 kWh | 140 | $28,000 | $7,000 |
| 500 kWp | 700,000 kWh | 700 | $140,000 | $35,000 |
Adjusted Payback = System Cost ÷ (Annual Electricity Savings + Annual SREC Revenue)Practical Guidance
- Maximize production, not just self-consumption. In SREC markets, every additional kWh generates revenue regardless of whether it’s consumed on-site or exported. Size systems aggressively where SREC prices are strong.
- Include SREC revenue in proposal financials. Use the generation and financial tool to model SREC income alongside electricity savings for a complete ROI picture.
- Model SREC price sensitivity. Show customers three scenarios — current prices, 50% of current, and zero SRECs — to demonstrate the system pays for itself even without certificate income.
- Verify production metering requirements. Some SREC programs require revenue-grade meters (±2% accuracy). Confirm the monitoring setup meets program requirements during design.
- Register systems promptly. SREC registration must happen before the system can earn certificates. Delays mean lost revenue — register within the first month of commissioning.
- Install compliant production meters. The tracking system requires verified production data. Install meters that meet the state program’s accuracy and reporting standards.
- Guide customers on aggregators. Most residential customers benefit from SREC aggregator services that handle registration, reporting, and sales for a percentage fee (typically 5–15%).
- Document system capacity accurately. SREC programs verify that reported production is consistent with installed capacity. Discrepancies can trigger audits or disqualification.
- Lead with total value, not just bill savings. In strong SREC markets, certificate revenue can equal or exceed electricity savings. Show both revenue streams in proposals.
- Explain the SREC mechanism clearly. Most homeowners don’t understand SRECs. Use simple language: “You earn a bonus payment for every 1,000 kWh your system produces.”
- Recommend long-term SREC contracts. Locking in SREC prices through multi-year contracts provides predictable income and protects against market downturns.
- Disclose price volatility. Be transparent that SREC prices can fluctuate. Customers who understand the risk upfront are more satisfied long-term.

Real-World Examples
Residential: 8 kWp System in New Jersey
A homeowner installs an 8 kWp system producing 10,400 kWh/year (specific yield of 1,300 kWh/kWp). The system generates 10.4 SRECs annually. At the current TREC price of $200, annual SREC revenue is $2,080. Combined with $1,600/year in electricity savings, the system’s total annual benefit is $3,680, achieving payback in 5.4 years.
Commercial: 200 kWp Installation in Washington DC
A commercial building installs a 200 kWp rooftop system producing 260,000 kWh/year. At DC’s SREC price of $380, the 260 SRECs generate $98,800/year in certificate revenue alone. This makes the project financially viable even with modest self-consumption, achieving a 3.2-year payback when combined with electricity savings and the federal ITC.
Residential: 6 kWp System in Pennsylvania
A 6 kWp system in Pennsylvania produces 7,800 kWh/year (7.8 SRECs). At $8/SREC, annual certificate revenue is just $62 — negligible compared to $1,200 in electricity savings. In weak SREC markets, the certificates are a minor bonus rather than a primary financial driver.
SREC Market Outlook
The SREC landscape is shifting. Several trends are reshaping how solar professionals should approach certificate revenue:
| Trend | Impact | Timeline |
|---|---|---|
| Transition to fixed incentives | States moving from open-market SRECs to fixed-rate programs (e.g., MA SMART, IL ABP) | Ongoing |
| Increasing solar carve-outs | Higher mandates create more demand for SRECs, supporting prices | 2025–2035 |
| Supply growth | More installations increase SREC supply, putting downward pressure on prices | Continuous |
| Policy uncertainty | RPS targets can be modified by state legislatures, creating market risk | Variable |
Always check the Solar Alternative Compliance Payment (SACP) for your state. The SACP is the penalty utilities pay if they don’t have enough SRECs — it effectively sets the ceiling price for SRECs in that market. If SREC prices approach the SACP, the market is tight and prices may hold.
Frequently Asked Questions
How much is an SREC worth?
SREC prices vary widely by state and market conditions. In 2025–2026, prices range from under $10 in oversupplied markets (Pennsylvania, Ohio) to over $350 in supply-constrained markets (Massachusetts, Washington DC). New Jersey SRECs trade around $180–$230. Prices change monthly, so check current spot prices before quoting to customers.
Do all solar systems qualify for SRECs?
No. SRECs are only available in states that have a solar carve-out within their Renewable Portfolio Standard. As of 2026, roughly a dozen US states have active SREC or SREC-equivalent programs. The system must also be registered with the state’s tracking platform and meet metering requirements to earn certificates.
Are SRECs taxable income?
Generally yes. SREC income is typically considered taxable income by the IRS. For residential systems, it’s usually reported as ordinary income. For commercial systems, it’s part of business revenue. However, tax treatment can vary — consult a tax professional for your specific situation. Some states may treat SRECs differently for state tax purposes.
What happens to SRECs if net metering is eliminated?
SRECs and net metering are separate programs. Eliminating net metering would reduce electricity bill savings but would not affect SREC eligibility or revenue. SRECs are based on production, not export. In fact, if net metering is reduced, SREC revenue becomes a more important part of the financial case for solar.
