Net Metering: How to Earn Money from Solar
Net metering allows you to sell excess solar energy back to the grid and receive credits on your electricity bill. The amount you can earn depends on your location, local rates, and how much surplus power your system generates. Most homeowners save $10,000 to $30,000 over 25 years through net metering benefits.
Understanding Net Metering Basics
Net metering is a billing arrangement where your solar system connects to the utility grid through a special two-way meter. Here’s how it works: during daylight hours when your panels produce electricity, you use what you need and send excess power back to the grid. Your utility company credits you for that exported energy at a predetermined rate—often the same rate you pay for electricity consumption.
The “net” part refers to the net difference between what you generate and what you consume. If your system produces 20 kWh on a sunny day but you only use 15 kWh, that extra 5 kWh is credited to your account. At night or on cloudy days when your panels produce less, you draw power from the grid and use those credits.
This arrangement creates a natural energy storage solution without requiring expensive battery systems. Your utility becomes your virtual battery, storing excess production and making it available when you need it. Most net metering programs credit you monthly or annually, depending on your utility’s policies.
How Much Can You Actually Earn?
Your earnings from net metering depend on several key factors. The most important is your local electricity rate—customers in high-cost areas like California, Massachusetts, and New York can earn significantly more than those in states with cheaper electricity. Some utilities pay $0.12 per kWh while others pay $0.25 or more.
Your system size matters tremendously. A typical residential solar installation produces between 6,000 to 12,000 kWh annually. If your utility credits you at $0.15 per kWh and you export 3,000 kWh yearly (after using your own production), that’s $450 in annual credits. Over 25 years, that represents $11,250 in cumulative savings.
Geographic location and climate affect production. Sunnier regions generate more power, increasing export potential. A home in Arizona might produce 15% more electricity than an identical system in Ohio, directly increasing net metering credits.
Your consumption patterns also play a role. If you use most power in the evening after your panels stop producing, you’ll export more excess generation. Conversely, homes with high daytime usage will export less. Time-of-use rates offered by some utilities can increase earnings if excess generation happens during peak-rate hours.
Important caveat: net metering policies are changing. Some states are reducing credit rates or implementing new rules. California recently reduced its net metering compensation, affecting new installations. Before investing in solar, verify your specific utility’s current and planned net metering policies.
Net Metering Policies by Region
Net metering availability varies dramatically across the United States. Roughly 38 states and Washington, D.C. offer some form of net metering, but rules differ significantly.
States with strong net metering include Massachusetts, New York, and Oregon, which provide credits at full retail rates. These states allow homeowners to maximize earnings because credits equal the price they’d normally pay for electricity.
Some utilities offer “net billing” instead, crediting excess generation at a lower wholesale rate rather than retail rates. This reduces earnings but still provides meaningful savings. Other regions implement “non-bypassable charges,” where you pay additional fees even for self-generated energy.
A few states have no net metering programs, though alternatives like solar rebates or performance contracts exist. Texas and parts of the Southeast fall into this category, though this landscape continues evolving.
Your utility company matters more than your state in some cases. Municipal utilities and rural electric cooperatives have different policies than large investor-owned utilities. Before purchasing, contact your utility directly to confirm they offer net metering and understand their specific terms, rate structures, and any pending changes.

Frequently Asked Questions
Do I need a special meter for net metering?
Yes, your utility must install a net metering meter (also called a two-way or smart meter) to track power flowing both directions. The good news: utilities typically install this at no charge as part of your solar connection process. This advanced meter records how much electricity your system exports versus how much you consume, automatically calculating your monthly credits or charges.
What happens if I produce more electricity than I use each month?
This depends on your utility’s specific policies. Some utilities roll excess credits forward to future months, allowing you to accumulate benefits during summer production for use during winter. Others reset credits annually, meaning you lose unused credits at year-end. A few utilities pay cash for excess production at a reduced rate. Always clarify your utility’s rollover and reset policies before installation.
Can net metering reduce my electric bill to zero?
It’s theoretically possible but impractical for most homeowners. You’d need to perfectly match your annual production to annual consumption, accounting for seasonal variations and system losses. Additionally, most utilities charge a base customer service fee even if you generate all your own electricity. A well-designed system typically reduces your bill by 80-90%, with most homeowners still owing $15-30 monthly for grid connection fees and minor consumption during high-usage seasons.
