Can you sell electricity? In most of the United States, yes, but almost always only to your utility through an approved program such as net metering or net billing. Selling power directly to a neighbor, a tenant, or a nearby business usually makes you an unlicensed public utility under state law, which can trigger cease-and-desist orders, daily fines, and voided contracts. The legal path runs through your utility and your state’s Public Utility Commission, and the money you can make has shrunk in a growing number of states as regulators replace retail-rate credits with lower avoided-cost payments.
Selling to Your Utility
The federal foundation for selling small-scale electricity is the Public Utility Regulatory Policies Act of 1978 (PURPA), which forced regulated utilities to buy power from independent generators known as “qualifying facilities.” Congress capped the purchase price at the utility’s “avoided cost,” meaning the utility pays only what it would have spent to generate or buy the same electricity elsewhere.1Federal Register. Qualifying Facility Rates and Requirements Implementation Issues Under the Public Utility Regulatory Policies Act That framework still underpins how most homeowners get paid for exported power today.
In practice, you’ll interact with one of two state-level programs. Under traditional net metering, your meter effectively runs backward when your panels produce more than you use, and the utility credits the surplus at the full retail rate you pay for the electricity you draw. Roughly 40 states and the District of Columbia offer some form of net metering or community solar program.
That full-retail model is giving way to net billing. Utilities have argued that net-metered customers shift grid costs onto non-solar ratepayers, and regulators in a growing number of states have responded by crediting exports at the lower avoided-cost rate rather than the retail price. The gap is substantial. Retail rates commonly fall between $0.15 and $0.30 per kilowatt-hour; avoided-cost credits often land between $0.04 and $0.10. Over a 25-year system life, that difference can represent tens of thousands of dollars. Some states soften the transition with bonus credits for early enrollees or locked-in export prices for an initial period, but the direction of travel is clear. If you’re sizing a system to pay for itself, the compensation structure your utility uses matters more than almost any other variable.
Why You Usually Can’t Sell to a Neighbor
Each state defines “public utility” in its own statutes, and that definition decides whether selling your surplus solar power to the house next door turns you into one. In most states, it does. Operating as an unregulated utility without the proper certification can bring cease-and-desist orders, daily fines, and the forced unwinding of any sales agreements. Dollar amounts and enforcement aggressiveness vary widely.
This is the line that catches well-intentioned homeowners. The utility is a legal buyer for your surplus. Other consumers generally are not. The narrow exceptions involve specific statutory carve-outs, like certain commercial landlords who bundle electricity into lease payments, or entities that qualify under limited-capacity exemptions. If you’re considering any arrangement outside standard net metering, check your state’s utility commission rules before you sign anything.
Third-Party Power Purchase Agreements
A power purchase agreement (PPA) lets a third-party developer install and own a solar system on your property, then sell the electricity it generates back to you at a contractual rate, usually below the utility’s retail price. You get cheaper electricity without the upfront cost of ownership, and the developer earns revenue from the energy sales.2US EPA. Understanding Third-Party Ownership Financing Structures for Renewable Energy
The legal catch is the same public-utility question in a different costume. If a state’s definition of “public utility” is broad enough to cover anyone selling electricity to an end user, a PPA provider may need the same regulatory approval as the local power company, which is economically impractical for a rooftop solar business. The result is a patchwork: PPAs are clearly legal and common in some states, flatly prohibited in others, and in a gray area in the rest. Violating these restrictions can nullify the contract outright, leaving both the developer and the property owner exposed. Before signing, confirm your state explicitly permits PPAs.
Community Solar and Virtual Net Metering
If your roof is shaded, you rent, or you simply don’t want panels on your property, you can still participate financially. Community solar lets you subscribe to a share of a larger off-site installation. The electricity your share produces feeds the grid, and you receive bill credits proportional to your subscription through a mechanism called virtual net metering.
Subscribers typically pay the community solar provider for their share of output at a rate below retail electricity prices, then receive credits on their utility bill for the energy generated. Net savings usually run 5% to 20% off your electricity costs, depending on program terms and your utility’s credit rate. Before subscribing, check contract length, cancellation fees, and whether the credit rate is locked or variable.
Renewable Energy Certificates
When your panels generate electricity, they produce two separate things: the physical power and the environmental attributes of clean generation. Those attributes are packaged into Renewable Energy Certificates (RECs). Each REC represents one megawatt-hour of renewable electricity and trades as an asset independent of the power itself.3US EPA. Renewable Energy Certificates (RECs)
To sell them, your system must be registered with a regional tracking system that verifies your generation data. The two largest are the Generation Attribute Tracking System (GATS), covering much of the eastern United States, and the Western Renewable Energy Generation Information System (WREGIS) in the west.4US EPA. Energy Attribute Tracking Systems Registration produces a verified record that lets you list your RECs on market exchanges, where utilities and corporations buy them to meet renewable mandates or sustainability commitments.
Prices swing hard by region. In states with aggressive renewable portfolio standards and active Solar Renewable Energy Certificate (SREC) markets, the certificates can be worth meaningful money. In states without mandates, the voluntary market pays far less. Most residential owners sell through aggregators that handle registration, tracking, and trading in exchange for a cut; longer-term deals offer more price certainty but lower per-REC returns. One trap to watch for: if your net metering agreement or PPA contract assigns the RECs to the utility or developer, you don’t own them and can’t sell them. Verify REC ownership before you assume you have something to trade.
Aggregated Sales Into Wholesale Markets
FERC Order No. 2222, issued in September 2020, requires regional grid operators to let aggregations of distributed energy resources (rooftop solar, batteries, electric vehicles, and similar small systems) participate directly in wholesale electricity markets. Aggregations can be as small as 100 kilowatts, so groups of residential systems can band together to sell into markets that were previously reserved for large power plants.5FERC. FERC Order No. 2222 Explainer – Facilitating Participation in Electricity Markets by Distributed Energy Resources Implementation has rolled out in phases across regional operators, so availability depends on where you live, but the legal framework is now in place nationwide. In practice, participation runs through an aggregator rather than homeowner-by-homeowner.
What Approval to Export Power Actually Requires
Selling to your utility requires an interconnection agreement, and that process has both equipment and paperwork components. The hardware centerpiece is your inverter, which converts your panels’ DC output into grid-compatible AC. Most utilities now require inverters certified to UL 1741, which ensures the equipment safely disconnects from the grid during an outage so your system doesn’t backfeed into lines that utility crews may be repairing.6California Energy Commission. Changes to Inverter and Energy Storage System Listing Requirements for UL 1741 Supplement SB Safety Standards Newer interconnection rules increasingly require “smart” inverters that comply with IEEE 1547-2018 and carry UL 1741 Supplement SB certification, which cover grid-support functions beyond basic anti-islanding. If you’re buying now, confirm your inverter carries the latest certification.
Your installer submits an application to the utility, typically through an online portal, including the system’s nameplate capacity, equipment specifications, a one-line electrical diagram, and a site map showing the location of the disconnect switch. For straightforward residential systems, the technical review typically takes one to three weeks. Larger or more complex installations take longer, especially if the utility must study whether your local distribution circuit can absorb the added generation.
A field technician then inspects the installation to confirm it matches the submitted diagrams and meets safety codes; some utilities now handle this with a photo-based virtual review. The utility installs or activates a bidirectional smart meter and issues a Permission to Operate letter, which is your legal authorization to energize the system and begin earning credits. Do not turn the system on before that letter arrives. Operating without permission can void your interconnection agreement and create liability exposure. Budget for application fees, inspection fees, local building permits, and possible meter upgrade charges, none of which are typically included in a solar installer’s headline price.
Taxes on What You’re Paid
Standard net metering credits are generally not treated as taxable income. When your meter spins backward and reduces your bill, the IRS views that as a reduction in your electricity cost rather than a sale, so there’s no income to report. The picture changes if you receive actual cash payments for exported energy rather than bill credits, or if you sell through a feed-in tariff or similar direct-payment arrangement. Those payments may constitute taxable gross income. The IRS has not issued comprehensive formal guidance on every distributed generation payment structure, so if your arrangement goes beyond bill credits, a tax professional familiar with energy transactions is worth the fee.
On the installation side, the federal Residential Clean Energy Credit under Section 25D of the tax code provided a 30% credit for solar panels, battery storage, and other qualified clean energy property installed at your home, applying to systems placed in service from 2022 through December 31, 2025.7Internal Revenue Service. Residential Clean Energy Credit According to current IRS guidance, the credit is not available for property placed in service after that date.8Office of the Law Revision Counsel. 26 USC 25D – Residential Clean Energy Credit Clean energy tax incentives have been subject to frequent congressional action, so check the IRS website for any updates before relying on current rules.
Insurance Obligations
Most residential installations under 25 kilowatts don’t trigger additional insurance requirements beyond your existing homeowner’s policy, though you should confirm with your insurer that the system is covered against damage and that your liability limits are adequate. Larger systems are different. Utilities commonly require dedicated general liability insurance for interconnected systems above 40 kilowatts, with minimum coverage of $1 million or more per occurrence. For commercial-scale projects, the minimum often jumps to $2 million or higher.
Your interconnection agreement will include indemnification language holding you responsible for any damage your system causes to the grid or to utility workers, and it typically requires you to maintain coverage for the full duration of the interconnection. Letting the policy lapse can be grounds for the utility to disconnect you. If your system is large enough to trigger these requirements, factor the annual premium into your payback math, because it’s a recurring cost many project models quietly leave out.
