SRECs: What Are Solar Renewable Energy Credits?

Utility companies in some states must supply a set amount of renewable, and in some cases, specifically solar, energy. How do the companies prove they’re supplying, or at least funding, this clean energy?

Solar renewable energy credits allow utility companies to buy solar power from home solar system owners. So, in Delaware, Illinois, Maryland, Massachusetts, New Jersey, Ohio, Pennsylvania, Virginia, and Washington, D.C. solar owners can make a little money by selling SRECs. Here’s more on how SRECs work and who can benefit from them.

What Are Solar Renewable Energy Credits (SRECs)?

Solar renewable energy credits, also known as solar renewable energy certificates, are a way to sell the renewable benefits created by solar power, and create a market for those benefits. SRECs quantify and verify how much solar electricity a home or business produces and allows utilities to pay for that solar production.

One SREC represents 1,000 kilowatt-hours (kWhs) or 1 Megawatt-hour (MWh) of solar electricity generated.

SRECs help utility companies and power plants meet clean energy goals and renewable portfolio standards. Where SREC markets exist, SRECs can be an additional revenue stream for solar panel owners.

Who Buys and Sells SRECs?

Not all states have SREC markets, only those with renewable portfolio standards and sometimes the states bordering them. 

Renewable portfolio standards require utility companies to produce a certain percentage of their energy from renewable energy sources. If they can’t generate the electricity themselves, utilities can purchase SRECs as proof they paid someone, including people with home solar panels, to produce that renewable electricity. 

With SRECs, the utility is essentially buying the exclusive right to count someone else’s clean energy production from solar panels as their own. Often SRECs can only be bought and sold in the state they were generated in, but sometimes states allow SRECs from neighboring states.

Some solar companies, financing companies, electricity suppliers, and related industry organizations also purchase SRECs upfront from solar panel system owners to reduce up-front installation costs and sell the credits once they have been created.

What Is an SREC Worth?

SREC prices vary by state and supply and demand. States with renewable portfolio standards with higher requirements for solar energy typically have higher SREC prices.

Two factors determine the SREC prices:

• Supply and demand: The relationship between the amount of SRECs people create, and the amount of SRECs utilities need to buy.
• Solar alternative compliance payment (ACP): ACP is a tax or penalty created to ensure a utility company meets the state’s renewable energy goals. If the utility company doesn’t buy enough credits, they must pay the ACP. The upper limit of an SREC’s price is usually the same or similar to the ACP.

SREC values can depend on how it’s sold, either on the spot market or by contract. With a spot market, credits are sold every month, or every quarter, for their current value. With a contract, the solar system owner locks in a fixed price per SREC for a multi-year period.

Spot market prices are generally higher, but they can fluctuate, while sales on a contract have lower valuations, but the earnings are more consistent over the contract period.

In general, the typical homeowner in an SREC market can expect to earn $10-$100 for each credit they sell and will generate 10+ credits per year. However, as mentioned, this SREC value can change significantly depending on many factors.

How Do I Sell SRECs?

SRECs are bought and sold on markets.

Utility companies want to minimize their costs, so they want to purchase SRECs from the fewest number of sellers possible. As a result, the easiest way for homeowners to sell SRECs are through brokers that aggregate and sell SRECs to utilities.

SREC markets don’t exist in every state, but they do in Delaware, Illinois, Maryland, Massachusetts, New Jersey, Ohio, Pennsylvania, Virginia, and Washington, D.C.. 

How Does the SREC Market Work?

SRECs are commonly bought and sold online through an intermediary, or an SREC aggregator. Top platforms for buying and selling SRECs include SRECTrade, Sol Systems, and Knollwood Energy.

(NOTE: If you go solar with Palmetto, we can help you sign up with SRECTrade, our partner and national SREC brokerage firm, to sell your SRECs. SRECTrade has a seamless sign-up process when you go solar with us, so you just sign the documents we provide, and Palmetto handles the application process.)

An SREC is first sold by renewable energy producers, and can then be aggregated and traded by energy industry brokers, retail electric providers, and utility companies. This creates a market for those certificates and gives them value.

Homeowners and businesses can sell certificates directly to utilities or through aggregators. However, most utilities prefer to buy a large number of credits through a single aggregator, instead of buying small quantities of credits from a large number of individual producers.

SRECs and RECs: What Is the Difference?

A renewable energy certificate (REC) represents the environmental benefits associated with one MWh of electricity generated from renewable energy, including solar and wind. Each REC is a legal claim the electricity came from 100% renewable energy sources.

A solar renewable energy credit (SREC) takes things a step further by confirming that 100% of the energy used to make that clean electricity came from solar power. Because some states have defined solar generation requirements in addition to renewable energy generation requirements, the certificates help keep track of solar electricity.

Frequently Asked Questions

How much are SRECs worth?

The value of SRECs varies with supply and demand. That means they are worth different amounts depending on the state they’re sold in and when they’re sold. It’s not uncommon to see SREC prices range from $10-$100.

How do SRECs work?

Utility companies buy SRECs to fulfill their legal obligations to source a certain amount of solar energy. Solar panel owners in areas with SREC markets can sell the SRECs their solar panels generate and earn a bit more money.

What is the downside of SRECs?

Selling your SRECs upfront on a contract may earn you less money, but that depends on what the SREC market in your state does over the length of that contract.
