SRECs Explained: How Solar Certificates Earn You Money
SRECs (Solar Renewable Energy Certificates) are tradable credits you earn for the solar electricity your system generates — typically one SREC per 1,000 kWh — which you sell to utilities for ongoing income on top of your bill savings. Active markets exist in states like New Jersey, Massachusetts, Maryland, Pennsylvania, Ohio, Illinois and Virginia, where SRECs can add thousands of dollars over your system's life.
What are SRECs?
An SREC — Solar Renewable Energy Certificate — is a tradable credit representing the environmental, non-power attributes of solar electricity. You earn one SREC for roughly every 1,000 kWh (1 MWh) your system generates, and you can sell those certificates for cash — income that's separate from and on top of the money you save on your electricity bill.
SRECs exist because of state Renewable Portfolio Standards (RPS) with a solar ‘carve-out’: laws requiring utilities to source a set percentage of their power from solar. To comply, utilities buy SRECs from solar owners like you. In effect, the utility pays you for generating solar so it can meet its legal solar obligation — turning your panels into a small income stream as well as a bill-cutter.
How SRECs work
The mechanics are straightforward once you see the flow:
- Your solar system generates electricity, tracked by a meter or monitoring system.
- For roughly every 1,000 kWh produced, you earn one SREC.
- You sell your SRECs — through a broker, aggregator, or directly — into your state's SREC market.
- Utilities buy them to meet their Renewable Portfolio Standard solar requirement.
- You receive cash, on top of your electricity bill savings.
A typical 7–8 kW system generates around 9–11 SRECs per year. Multiply that by the SREC price in your state and you have an annual income stream that can run for years — check your production assumptions with our panel-count guide.
Which states have SREC markets
SRECs only have value where a state has an RPS with a solar carve-out and an active market. Markets and rules change, but states with notable SREC activity include:
| State | Program note |
|---|---|
| New Jersey | SuSI / SREC-II successor program |
| Maryland | Active SREC market |
| Pennsylvania | SREC market |
| Ohio | SREC market |
| Illinois | Illinois Shines (15-yr SREC block, paid upfront) |
| Virginia | Growing SREC market |
If you're not in an SREC state, you still have the core economics — net metering and bill savings — you simply don't have this extra income stream. With the 30% federal credit gone for 2026 installs, that difference matters more than it used to. Check your state on the incentives hub.
SREC prices and how they vary
SREC prices vary enormously by state and over time, driven by supply and demand: how many solar systems are producing SRECs versus how much solar utilities are required to buy. In tight markets SRECs have sold for hundreds of dollars each; in oversupplied ones they can be worth much less.
Because prices fluctuate, SREC income is less predictable than your bill savings — treat it as a valuable bonus, not the foundation of your solar economics. Many states have a SACP (Solar Alternative Compliance Payment) that effectively caps SREC prices (it's the fine utilities pay if they don't buy enough SRECs, so SRECs rarely exceed it). Knowing your state's current SREC price and SACP helps you estimate realistic income.
How much can SRECs earn you?
The income depends on your production and your state's SREC price. As a rough illustration: a 7–8 kW system producing ~10 SRECs/year, in a market where SRECs trade at, say, $50–$200 each, earns roughly $500–$2,000 per year — potentially tens of thousands over the system's life in a strong market.
In the strongest historical markets (like New Jersey at its peak), SRECs covered a large share of the system's cost. Today's values are more modest in most states but still meaningful. Crucially, this is income on top of the electricity bill savings that drive your core payback — so where SRECs exist, they shorten payback and boost ROI. Just model them conservatively given price volatility.
How to sell your SRECs
You have a few options for selling SRECs:
- SREC aggregator/broker: the most common route — a company registers your system, tracks production, and sells your SRECs on your behalf for a fee or share.
- Spot market: sell SRECs individually at the current price — more upside if prices rise, more risk if they fall.
- Long-term contract: lock in a fixed price for several years — less upside, but predictable income.
- Upfront block (e.g., Illinois Shines): some programs pay a lump sum for 15 years of SRECs at install.
Your installer often helps register your system in the state's tracking platform; after that, an aggregator can handle the rest. Compare the fees and whether a fixed contract or spot sales suits your appetite for price risk.
SRECs vs net metering (and the ended tax credit)
It helps to see how SRECs fit alongside the other solar incentives, because they're often confused:
| Incentive | What it does |
|---|---|
| Federal tax credit (30%) | One-time cut to system cost — ended for installs after Dec 31, 2025 |
| Net metering | Credits the value of power you export |
| SRECs | Pays you for generating solar (income on top) |
Through 2025 all three stacked. For a system installed in 2026, the 30% credit is gone (it ended for installs completed after December 31, 2025), but net metering and SREC income still stack where available. SRECs are the only one of the three that pays you based purely on how much you generate, regardless of how much you use or export. Our net metering guide and tax credit guide cover the others.
Risks and what to watch
SRECs are a bonus, not a guarantee, so understand the risks. Prices are volatile and can fall as more solar comes online (more supply) or if a state weakens its RPS. Programs can change or close — some states have shifted from open SREC markets to fixed-incentive programs. And aggregator fees reduce your net income.
The practical guidance: when evaluating solar in an SREC state, model the SREC income conservatively (or even ignore it) so your decision stands on the solid ground of bill savings, with SRECs as upside. That discipline matters more in 2026: with no 30% federal credit to cushion an overpriced system, inflated SREC projections can hide a payback that runs well past 15 years. Don't let a salesperson justify an overpriced system with optimistic SREC projections — that's a variation of the inflated-savings red flag in our installer red flags guide.
Are SRECs worth pursuing?
If you live in an SREC state, yes — it's essentially free money for power you're generating anyway, and registering is straightforward (often handled with your installer and an aggregator). Even modest SREC income meaningfully improves your ROI and shortens payback, stacking on top of net metering — and in 2026, with the federal credit gone, SRECs are one of the few incentives that still meaningfully cut payback.
If you're not in an SREC state, there's nothing to pursue — your economics rest on net metering, bill savings and any state incentives. The 30% credit that used to anchor the math ended for 2026 installs, so expect paybacks roughly 35–45% longer than older guides quote. Either way, SRECs are a reason states like New Jersey, Maryland and Illinois rank among the best for solar payback (see best states for solar). Where they exist, take the free income; where they don't, you're not missing the core return.
How SREC programs evolve (SREC-II and beyond)
SREC programs aren't static — states adjust them as solar grows, and understanding the trend helps set expectations. The classic open SREC market (volatile, supply-and-demand priced) has in several states given way to successor programs with more fixed, predictable payments. New Jersey, for example, moved from a pure SREC market to SREC-II and then the SuSI program, which pays a fixed amount per MWh for 15 years — less upside than the old market's peaks, but far more predictable.
This evolution generally trades volatility for stability: newer programs often guarantee a set payment for a defined term, which makes it easy to estimate your income but caps the windfall potential the early markets had. When evaluating SRECs in your state, find out whether you're entering an open market or a fixed successor program, and for how long payments are locked — it changes how you value and sell the certificates.
Tracking and registering your system
To earn SRECs, your system must be registered in your state's tracking platform (regional systems like PJM-GATS or NEPOOL-GIS handle the certificate accounting). Registration ties your verified production to certificate issuance, so your generation is accurately converted into SRECs. Your installer or SREC aggregator usually handles this setup as part of getting you started.
Once registered, your production is reported (via your meter or monitoring), SRECs are minted as you generate, and your aggregator or chosen sales channel handles the transactions. There's modest paperwork up front and then it's largely passive income. Make sure registration is completed promptly after your system goes live, since SRECs are only earned once you're enrolled — an aggregator can walk you through it if your installer doesn't.
A worked SREC income example
To make it concrete: suppose you install a 7.5 kW system in an SREC state, producing about 10,500 kWh a year — roughly 10–11 SRECs annually. If your state's SRECs sell for around $100 each, that's about $1,000–$1,100 per year in SREC income, on top of your electricity bill savings.
Over a 10–15 year SREC eligibility window, that could total $10,000–$15,000 — a meaningful chunk of the system's cost. In a higher-priced market the figure is larger; in a lower-priced one, smaller. Layered on top of net metering, this extra income is exactly why SREC states like New Jersey and Maryland rank among the fastest for solar payback — and with the 30% federal credit gone for 2026 installs, it now does even more of the heavy lifting. Run your own production and payback in the Payback Calculator, then treat SREC income as upside on top.
