Most people who sell electricity do it from their own rooftop: install solar panels, generate more power than you use, and send the surplus to the grid in exchange for credits or cash. But selling electricity can also mean enrolling your home battery in a virtual power plant program, earning certificates for clean energy you produce, or, at a larger scale, selling wholesale power through regional energy markets. Each path has different equipment requirements, compensation structures, and paperwork.
Selling Solar Power Through Net Metering
The most common way homeowners sell electricity is through net metering. When your solar panels produce more power than your home needs, the excess flows onto the grid, and your utility gives you a credit on your bill. In states with full retail-rate net metering, you’re credited at the same price you’d pay to buy that electricity, often between $0.12 and $0.21 per kilowatt-hour depending on your utility and region. Your meter essentially runs backward during sunny hours, offsetting power you draw at night or on cloudy days.
Credits typically roll over month to month. At the end of an annual billing cycle (sometimes called a “true-up”), any remaining excess is settled at a lower rate. That lower rate is usually the wholesale or supply-only portion of your electricity cost, which strips out the delivery and distribution charges you normally pay. In practice, this supply-only rate can be roughly half the full retail rate. So the goal for most solar homeowners is to size their system to match annual usage closely rather than massively overproduce.
Net metering policies vary significantly by state, and several utilities are pushing to replace the traditional one-to-one credit with lower compensation models. Some proposed changes would pay you based on hourly wholesale market prices rather than your retail rate. Those wholesale rates can average just $0.04 to $0.08 per kilowatt-hour, representing a 40 to 60 percent reduction in the value of your exported solar. If you’re considering a solar installation, check whether your utility has proposed or adopted changes to its net metering tariff. Systems installed before a policy change are sometimes grandfathered under the old, more generous rates.
Getting Permission to Connect
You can’t just wire solar panels to the grid on your own. Every utility requires an interconnection agreement before you can legally export power. The process typically works like this:
- Submit an application. You’ll provide details about your system’s size, location, and inverter specifications. Most utilities also require a one-line electrical diagram and a site plan. Expect to pay an application fee.
- Sign the interconnection agreement. Your utility will send a formal contract. Your solar installer usually handles this, but you should confirm who is responsible for signing it. Some utilities also require a separate net metering agreement.
- Pass inspection and receive permission to operate. After installation, the utility will typically send an engineer for a witness test, confirming your system is properly wired, safety equipment is labeled correctly, and the inverter meets technical standards. Do not energize your system until you have written permission to operate (PTO) from the utility. Operating before PTO can create safety hazards and may violate your agreement.
For a typical residential solar installation, this process takes anywhere from a few weeks to a few months depending on your utility’s backlog. Your installer will usually manage the paperwork, but delays in utility review are common, so ask about timelines upfront.
Virtual Power Plants and Battery Programs
If you have a home battery (or an electric vehicle with vehicle-to-grid capability), you may be able to earn money by enrolling in a virtual power plant, or VPP. A VPP aggregates thousands of small energy sources, like home batteries, smart thermostats, and EV chargers, and coordinates them to behave like a single large power plant. When the grid needs extra power during a heat wave or a cold snap, the VPP operator signals enrolled devices to discharge stored energy or reduce consumption.
The Department of Energy describes VPPs as providing “utility-scale and utility-grade grid services,” meaning your battery isn’t just helping your household. It’s actively supporting grid reliability. In return, participants receive compensation that can take the form of bill credits, flat annual payments, or per-event payments during peak demand periods. The exact compensation depends on your utility or the third-party VPP program you join. Some programs pay $200 to $500 per year for a single home battery, while others offer higher payments tied to the number of events you participate in.
Eligible devices typically include rooftop solar paired with batteries, standalone battery systems, EV chargers, and even electric water heaters with smart controls. Enrollment is voluntary, and most programs let you set limits on how much your battery can be discharged so your home still has backup power when you need it.
Solar Renewable Energy Certificates
In some states, your solar panels generate something valuable beyond electricity: renewable energy certificates, or SRECs. For every 1,000 kilowatt-hours (one megawatt-hour) your system produces, you earn one SREC. These certificates can be sold to utilities that need them to meet state renewable energy mandates. The income from SRECs is separate from whatever you earn through net metering.
SREC prices fluctuate based on supply and demand within each state’s market. In states with aggressive renewable portfolio standards and limited solar capacity, prices can be substantial, sometimes $50 to $300 or more per certificate. In states with abundant solar supply, prices may be far lower. Not every state has an SREC market; this revenue stream exists only where state policy requires utilities to purchase a certain percentage of their power from solar specifically. You can sell SRECs through brokers, online trading platforms, or aggregation services that handle the registration and sales process for a commission.
Selling Wholesale Power at Scale
Selling electricity at a commercial scale is a different business entirely. Independent power producers, sometimes called IPPs, generate electricity from solar farms, wind installations, natural gas plants, or other sources and sell it through wholesale energy markets. These markets are managed by regional transmission organizations (RTOs) and independent system operators (ISOs), which run auctions where generators bid to supply power.
The Federal Energy Regulatory Commission oversees these wholesale markets. Participants include power generators, energy storage providers, demand response companies that get paid to reduce load during peak periods, and utilities purchasing energy to serve their customers. Generators bid how much power they can provide in megawatts and at what price. The RTO or ISO then selects the lowest-cost bids needed to meet forecasted demand.
There’s no single minimum system size written into federal rules for market participation, but the practical barriers are significant. You’ll need to register as a market participant with your regional RTO or ISO, meet their technical and financial requirements, and invest in metering and communication equipment that allows real-time dispatch. Most wholesale market participants operate systems measured in megawatts, not kilowatts. For context, a single megawatt of solar capacity can cost $1 million or more to build, and wholesale electricity prices typically range from $0.03 to $0.07 per kilowatt-hour, meaning the margins are thin and the upfront capital is large.
Choosing the Right Path
Your best option depends on what you already have and how much you want to invest. If you own or are planning to install rooftop solar, net metering is the simplest starting point. Add a home battery, and you can layer on VPP income while also having backup power during outages. If your state has an SREC market, register your system to earn certificates on top of your net metering credits.
For anyone thinking bigger, selling wholesale electricity requires serious capital, regulatory knowledge, and a tolerance for market risk. Community solar projects offer a middle ground: developers build a shared solar installation and sell subscriptions to local residents, earning revenue from both electricity sales and renewable energy credits without requiring each customer to install their own panels. If you’re interested in that model, you’d typically partner with a solar developer and secure a power purchase agreement with a local utility before breaking ground.
