Explaining Solar Renewable Energy Certificates

Renewable Energy Certificates

Solar Renewable Energy Certificates (SRECs) are highly advantageous and complex among the various rewards for installing solar panel systems. Nevertheless, SRECs can offer significant financial gains for solar power system owners in qualifying regions.

What is an SREC?

An SREC, or Solar Renewable Energy Certificate, is a tradable commodity representing the environmental benefits of generating one megawatt-hour (MWh) or 1,000 kilowatt-hours (kWh) of electricity using solar power. Each MWh generated for homeowners with solar panel systems allows you to earn one SREC, which can be sold on an open market. This offers a supplemental income stream on top of the electricity cost savings from the solar system itself.

Role in Renewable Portfolio Standards (RPS)

The concept of SRECs arises from legislative policies known as Renewable Portfolio Standards (RPS). RPS mandates that a certain proportion of electricity generated by utility companies must come from renewable sources like solar, wind, or hydro. Failing to meet these quotas could result in penalties for the utilities.

Mechanism for Utility Companies

Utilities can buy SRECs as a way to meet their RPS obligations. When they purchase an SREC, they essentially buy the rights to claim that a specific amount of renewable energy was generated on their behalf. This allows them to offset their non-renewable energy production and comply with state regulations without necessarily generating the renewable energy themselves.


Think of an SREC like a golden ticket. Your solar panels generate electricity; with every 1,000 kWh, you get a “golden ticket.” You can then sell this ticket to Willy Wonka (the utility company), who needs these tickets to prove to the townspeople (regulatory agencies) that he’s making enough chocolate (energy) from sustainable sources like cocoa beans (solar power).

Potential Earnings from Selling SRECs

Potential Earnings from Selling SRECs

Average SREC Earnings for a 10 kW System

A 10 kilowatt (kW) solar panel system typically generates around 10 to 13 megawatt-hours (MWh) of electricity annually. This would mean you could earn 10 to 13 SRECs annually.

Regional Variations in SREC Prices

The financial benefits of selling SRECs can vary significantly depending on your geographic location. For instance, in jurisdictions like Washington D.C., where the demand for SRECs is high and the supply is limited, you might find prices as high as $400 to $500 per SREC. In contrast, in states where the supply of SRECs exceeds demand, you might only get around $15 to $20 per SREC.

Calculating Potential Earnings

To estimate your potential earnings, you’ll need to consider:

SRECs are 10 to 13 per year for a 10 kW system.
Price per SREC: Varies by state, ranging from $15 to $500.
Here are some hypothetical scenarios based on the range of SREC prices:

Scenario 1: High-Value Market (e.g., D.C.)
13 SRECs x $500/SREC = $6,500 per year
Scenario 2: Low-Value Market
10 SRECs x $15/SREC = $150 per year

Imagine your SRECs as pieces of a rare gemstone. You could make a small fortune in a market where these gemstones are in high demand and low supply. On the other hand, in a market flooded with these gemstones, you’d get much less for each piece.

Factors Influencing SREC Value

Factors Influencing SREC Value

Solar Renewable Energy Certificates (SRECs) are chiefly influenced by two primary factors: supply and demand dynamics and Alternative Compliance Payments (ACPs). In a market economy, the concept of supply and demand is straightforward: the price of a commodity like SRECs will rise if demand outstrips supply and will fall if supply exceeds demand. The number of SRECs in the market (supply) depends on the rate at which solar energy systems are installed and generate electricity.

The demand largely comes from utilities needing to meet their Renewable Portfolio Standards (RPS) and prefer buying SRECs as a less expensive alternative to generating renewable energy. On the other hand, ACPs act as a pricing safety mechanism. There are penalties that utilities must pay if they fail to meet their RPS obligations, effectively setting a ceiling price for SRECs. If the cost of an SREC rises above the ACP, utilities will opt to pay the ACP instead. Therefore, these two factors interplay to establish the price of SRECs in various state markets.

Geographic Variability

The value and availability of Solar Renewable Energy Certificates (SRECs) can vary considerably from one state to another due to differing Renewable Portfolio Standards (RPS) and the presence or absence of solar carve-outs.

SREC Markets by State

Some states have established SREC markets to facilitate the buying and selling of these certificates. The markets exist primarily in states with solar carve-outs, where legislation has mandated a specific portion of renewable energy must come from solar sources. States like Washington D.C., New Jersey, and Massachusetts have active SREC markets, whereas others like Texas or Florida do not.

High-Value vs Low-Value Markets

The worth of an SREC in different markets is determined by the balance, influenced by state policies. In states like Washington, D.C., where the demand for SRECs is high due to stringent RPS requirements and a lower supply of solar installations, an SREC can soar to several hundred dollars. On the contrary, in states where SRECs are more abundant, or the RPS requirements are less strict, the value may dip to as low as $15 to $20 per SREC.

Future Trends in solar

Future Trends

Projected Changes in SREC Markets

Market Maturity: As solar technology becomes more affordable and widespread, more states may adopt SREC markets. However, mature markets may see a decline in SREC prices due to oversupply.

Technological Advances: Improvements in solar panel efficiency could result in higher energy production, leading to more SRECs generated per installation. This could influence supply, potentially driving prices down if demand doesn’t keep pace.

Diversification of Renewable Energy Sources: As other renewable technologies like wind and hydro become more efficient and cost-effective, they could influence the RPS and, consequently, the demand for SRECs.

Policy Impacts on SREC Value

Changes in RPS: Alterations in Renewable Portfolio Standards, whether they become more stringent or lenient, can substantially impact SREC value. More stringent RPS could increase demand and prices, while lenient policies could have the opposite effect.

Federal Legislation: Any nationwide policies promoting renewable energy could standardize or even replace state-specific SREC markets. This would have a far-reaching impact on SREC values.

Tax Incentives and Subsidies: Government incentives for adopting renewable energy sources can also influence SREC markets indirectly by affecting the rate of solar installations and, thus, the supply of SRECs.

Analogies to Simplify Complex Topics

Stock Market Fluctuations: Like a publicly traded company whose stock prices change due to market conditions and regulatory environments, the value of SRECs is volatile and influenced by state-specific laws and generally renewable energy trends.

Fruit Market: Imagine SRECs as seasonal fruits in a market. If a new policy mandates the use of a particular fruit in every household, demand for that fruit will rise, as will its price. Similarly, policy changes can significantly impact the demand and value of SRECs.

Potential Rewards of SREC

The complexities and potential rewards of Solar Renewable Energy Certificates (SRECs) make them an intriguing aspect of the broader transition to renewable energy. Various factors shape their value, including supply and demand dynamics, state-specific policies like Renewable Portfolio Standards, and broader market and policy trends. With the ever-evolving landscape of renewable energy technologies and policies, staying informed about these variables can offer solar system owners an advantage in maximizing their return on investment. Overall, SRECs represent a financial opportunity for solar adopters and incentivize renewable energy and combat climate change.
