A clear net metering glossary with net billing, feed-in tariffs, and export rates worldwide in 2026. Compare policies and understand your solar savings.
This net metering glossary breaks down the terms that decide how you get paid for excess solar electricity. If you're comparing policies across countries or planning a system, these details directly affect your savings and how long it takes to recover your investment.
Think of it this way. Your panels produce energy, but the rules decide what that energy is worth once it leaves your roof.
What Is Grid Export Compensation?
Why solar export policies exist
Solar systems do not always match your home's demand in real time. When production is higher than use, the extra power flows into the grid. Utilities compensate that export because it adds supply and can reduce strain during busy hours.
The value they assign depends on local rules. Some grids need daytime solar more than others, and that shapes what they pay.
Key differences between self-consumption and export
Self-consumption means using your solar energy on-site, inside your home or business. This gives the highest value because each kilowatt-hour offsets what you would have bought at retail price.
Export works differently. You send unused energy to the grid and receive a credit or payment. That rate is often lower than what you pay for electricity, so using your own energy first matters more than exporting it.
Ask yourself a simple question: are you home during the day to use that energy, or does most of it go out to the grid?
How utilities value exported electricity
Utilities calculate export value in a few ways. Some match retail prices, others base it on avoided generation costs or wholesale market rates. Each method reflects how much the grid benefits from your energy.
In 2026, export compensation ranges from about 0.03 to 0.40 USD per kWh depending on policy and location. Higher values appear in parts of Europe, while lower rates show up in regions where solar supply is already high during the day.
Net Metering Explained
How billing works (kWh-for-kWh crediting)
Net metering is simple to grasp. The grid acts like a temporary battery. When you export one kilowatt-hour, you receive a credit close to the retail rate. Later, when you draw electricity, that credit offsets your bill.
This setup makes solar easier to justify financially because exported energy holds strong value.
Annual vs monthly settlement
Not all net metering programs settle credits the same way. Some close the balance every month. Others allow credits to roll over for a full year before settling.
Annual settlement can be more favorable. Summer overproduction can offset winter consumption, which smooths out seasonal changes.
It's a small rule with a big impact.
Where it is still used
Net metering remains active in parts of North America, the Middle East such as the UAE, and countries like Brazil. However, many regions started shifting toward other models between 2022 and 2025.
That shift happened because grids with high solar adoption need pricing that reflects time of use more accurately.
Net Billing Explained
Dual-rate structure (import vs export)
Net billing separates buying and selling. You pay the full retail rate for electricity you import, while exports are credited at a lower rate.
That export rate ranges from 0.03 to 0.15 USD per kWh. The gap between those numbers is what changes system economics.
Time-of-use export pricing
Some regions vary export rates by time of day. Midday solar may earn less because supply is high. Evening exports can be worth more when demand increases.
This pushes system owners to think about timing, not just total production.
Impact on payback periods
Lower export rates reduce the benefit of sending excess energy to the grid. As a result, systems that rely heavily on exporting take longer to pay back.
Adding a battery or shifting usage to daylight hours can improve returns under this model.
Feed-in Tariff (FiT) Explained
Fixed-rate contracts
A feed-in tariff pays a set price for every unit of electricity you export. The rate is defined by regulators and locked in for a contract period.
This structure removes uncertainty. You know exactly what each kilowatt-hour is worth.
Duration and guarantees
Contracts often run from 10 to 25 years. That long-term visibility helps with financial planning and loan decisions.
In Europe, modern FiT rates range from about 0.05 to 0.30 USD per kWh depending on system size and whether the system prioritizes export or self-use.
Partial vs full export FiT
Some FiT setups allow you to use part of your solar energy and sell the rest. Others require full export, where all generated electricity goes to the grid.
Full export systems are easier to model financially, but they do not reduce your own electricity bill.
Gross Metering Explained
Full export requirement
Gross metering sends all generated electricity to the grid. Nothing is used on-site.
That makes it very different from systems designed around self-consumption.
Separate consumption billing
You continue buying all your electricity from the grid at retail rates. At the same time, your solar production is sold separately at a fixed or regulated price.
It works like running a small power plant that sells everything it produces.
Typical use cases (commercial/utility-scale)
This model appears more often in commercial or industrial projects and in parts of Asia. Residential use is less common because it does not reduce on-site consumption.
Key Differences Between Models (Net Metering Glossary Comparison)
| Model Type | Compensation Mechanism | Typical Export Rate (USD/kWh) | Billing Method | Common Regions | Cash Payout vs Credit | System Design Impact |
|---|
| Net Metering | 1:1 or near-retail credit | 0.08, 0.40 | Net consumption offset | U.S. (some states), UAE, Brazil | Usually credit | Encourages larger systems |
| Net Billing | Wholesale/avoided cost rate | 0.03, 0.15 | Separate import/export pricing | U.S., Australia, South Africa | Credit or partial payout | Favors self-consumption and batteries |
| Feed-in Tariff | Fixed long-term contract | 0.05, 0.30 | All or partial export paid | Germany, parts of Europe | Often cash payout | Encourages export-oriented systems |
| Gross Metering | All generation sold | Approx. 0.04, 0.12 | Separate consumption billing | India (some states), commercial sectors | Cash payout | Requires precise system sizing |
Approvals, Permits, and Documentation
Interconnection agreements
Before exporting electricity, you need an agreement with your utility. This sets the rules for connecting your system and defines how compensation works.
Technical compliance (inverters, safety)
Utilities require certified equipment that meets grid standards. Inverters must shut down during outages and operate within voltage limits. These checks protect both your system and the wider grid.
Inspection and commissioning
Most projects require a standard set of documents:
- System design approval
- Grid interconnection application
- Inverter certification documents
- Safety compliance certificate
- Net meter installation request
Approval timelines range from 2 to 12 weeks depending on location and system size. Delays often come from missing paperwork rather than technical issues.
Many installers say paperwork is the slowest part of going solar. That tends to be true.
How Buyback Rates Are Set
Retail vs wholesale benchmarks
Net metering links export credits to retail electricity prices. Net billing ties them to wholesale or avoided costs. That difference explains the gap in value.
Time-of-use and dynamic pricing
Some regions adjust export value throughout the day. Electricity sent during high demand periods earns more than midday solar.
This pricing reflects real grid conditions rather than a flat rate.
Policy-driven vs market-driven rates
Feed-in tariffs are fixed by policy and remain stable for years. Net billing rates can change over time as market conditions shift.
Both approaches exist because grids face different challenges depending on solar adoption levels.
Country Examples (Global Snapshot)
North America example
Many areas in the United States moved from full net metering to net billing or hybrid structures. Export rates in some regions have dropped below 0.10 USD per kWh, which increases the value of self-consumption.
Europe example
Germany uses a structured feed-in tariff system with long-term payment certainty. Rates vary based on system design and whether energy is consumed on-site or exported.
Asia example
India applies a mix of net metering, net billing, and gross metering. Rules depend on the state and system size, especially above certain capacity limits.
Middle East/Africa example
Dubai offers a net metering framework with bill credits instead of cash payouts. In South Africa, export rules vary by municipality, and some areas limit or restrict exports entirely.
Australia example
Australia uses net billing, commonly called a feed-in tariff locally. Export rates range from about 0.03 to 0.12 USD per kWh. Some networks apply export limits during peak solar hours.
Choosing the Right System Based on Policy
When to prioritize self-consumption
If export rates are low, using your own energy becomes the priority. Running appliances during daylight hours or adjusting usage patterns can increase savings without changing system size.
Role of battery storage
Batteries store excess energy for later use instead of sending it to the grid at a lower rate. In net billing markets, this can improve financial returns.
It also gives you more control over when your energy is used.
System sizing strategies
System size should match your consumption and local policy. In strong net metering areas, slightly larger systems can make sense. In net billing regions, oversizing can reduce value because excess energy earns less.
Solar Bazaar provides practical tools to compare export rules and size systems based on real usage patterns across different markets.
Start with your local policy. Then estimate how much energy you will use versus export. Small adjustments in timing or system size can shift your financial outcome more than expected.
Solar Bazaar also offers guidance on interconnection steps and documentation, helping you avoid common delays during approval.
Once these terms are clear, comparing quotes becomes much easier. Solar Bazaar keeps its guidance neutral so you can focus on what works in your specific location.
