How State Net Metering Rules Affect Your Solar Returns

Your utility company probably hasn’t sent you a letter about this. They rarely do. But quietly, over the last three years, net metering rules have been rewritten in a dozen states, and a lot of homeowners who went solar expecting a certain payback period are now doing the math again.

I’ve been watching this happen since California’s NEM 3.0 rollout in April 2023, which cut the average export compensation rate by roughly 75% compared to NEM 2.0. Seventy-five percent. Homeowners who installed in 2021 under the old rules locked in compensation around $0.30 per kWh exported. New installations under NEM 3.0 are getting paid something closer to $0.08. That’s not a rounding error. That’s a fundamentally different financial calculation.

If you’re researching solar right now, or you installed recently and want to understand what changed, this is the article I wish someone had written before I spent hours on utility commission websites piecing it all together.

What Net Metering Actually Is (and Why the Definition Is Getting Blurry)

Net metering used to be simple. You send excess electricity to the grid, the utility credits your account at the full retail rate, and you “net” that against what you pull at night or on cloudy days. One kWh in equaled one kWh out, dollar for dollar.

That simplicity is exactly what utilities have been fighting. Their argument, which has some legitimate basis, is that retail-rate compensation doesn’t account for the actual cost of maintaining the grid that solar customers still rely on. Solar does provide real value, though: reduced strain during peak hours, deferred grid upgrades, and lower transmission losses. Both things are true simultaneously, and the honest answer is that the “correct” rate for exported solar power is genuinely complicated to calculate. States are landing in very different places.

Most people don’t realize the term “net metering” is increasingly being used to describe programs that look nothing like the original. Some states now call their programs net billing, value of solar tariffs, or avoided cost compensation. The name sounds similar. The math is very different.

The States That Have Cut Rates (and by How Much)

California gets the most attention because it’s the largest solar market in the country, but it’s not alone.

California went from full retail rate compensation under NEM 2.0 to a time-varying “avoided cost” rate under NEM 3.0, averaging around $0.05 to $0.08 per kWh depending on when you export. The California Public Utilities Commission built in a “grid benefits adder” that bumps up payments during peak hours, which is why NEM 3.0 heavily favors battery storage. Export midday when demand is low? You’re getting almost nothing. Discharge a battery during the 4-9 PM peak? The economics get considerably better. EnergySage’s market data shows California solar quotes now almost universally include storage. Two years ago, it was a minority option.

Nevada made its cuts earlier, back in 2015, then partially reversed them after public backlash. The state settled into a declining-rate structure where compensation drops as more solar penetration is added to the grid. Current export rates sit somewhere in the $0.09 to $0.11 range depending on the utility.

Arizona utilities have been chipping away at net metering for years. APS (Arizona Public Service) moved to an “export rate” well below retail, currently around $0.076 per kWh, while adding a demand charge component that can significantly increase the bills of solar customers who still pull peak power from the grid.

Utah switched from net metering to net billing in 2017. Compensation is now set at an “avoided cost” rate that’s lower than retail, and payback periods stretched noticeably.

Florida just went through a contentious battle. SB 1024 passed in 2022 and is phasing out full retail net metering, moving to avoided cost compensation by 2029. If you haven’t gone solar in Florida yet, the clock is ticking on the current rates.

Hawaii eliminated traditional net metering years ago. It replaced it with the Customer Self-Supply program (CSS) and Smart Export program, both of which pay well below retail for exports. The lesson from Hawaii, which solar installers know well: high grid electricity costs plus low export rates makes battery storage almost mandatory.

Texas is a different kind of complicated. There’s no statewide net metering mandate, so policies vary by utility, and most utilities aren’t required to offer any export compensation at all. ERCOT market dynamics make this its own conversation.

The States Still Offering Strong Net Metering (For Now)

Not every state has moved to cut compensation. Several states still have full retail-rate net metering, and a few have recently affirmed or expanded it.

New Jersey has strong net metering protections and has actually been debating an expansion of annual true-up periods. Massachusetts SMART program pays a separate incentive on top of net metering for certain customers, making it one of the more generous markets right now. New York is in a complicated transition with its VDER (Value of Distributed Energy Resources) tariff, which pays a blended rate based on location, time, and grid value. In some high-value zones in NYC, VDER actually pays more than retail. Most places, it pays less.

Illinois, Maryland, New Mexico, and Connecticut still have relatively strong net metering protections. Utility commission proceedings are happening in several of these states that could change things in the next two to three years though. Check current proceedings before assuming anything is locked in.

NREL tracks state-by-state net metering policies and their updates. Their database is the most reliable place to verify current rules since these change faster than most websites update.

How to Actually Figure Out What Your State’s Policy Means for Your Payback Period

Knowing the rate isn’t enough. You need to run the math against your actual consumption patterns.

Here’s the framework I use when helping someone evaluate a solar quote.

Start with your current monthly electricity bill and find your average consumption in kWh (it’s on the bill, usually as a 12-month average). Get the proposed system’s production estimate from your installer, broken down by month if possible. The gap between what you produce and what you consume in real time is what gets exported. That’s what the net metering rate applies to. In most homes, 20-40% of solar production gets exported to the grid rather than used on-site. Homes where people work during the day often export more.

Now multiply those estimated exported kWh by your state’s current export rate, not the retail rate, and see what that comes to annually. Compare that to what you’d have saved if you’d consumed all that power on-site at retail rates. That difference is the real cost of your state’s net metering policy, and it’s often $150 to $500 per year depending on system size and how your usage lines up with production.

A home energy monitor like the Emporia Vue (around $50-70 on Amazon) shows you how much power you’re pulling from vs. sending to the grid in real time. This helps you understand whether your consumption patterns are a good match for solar in your state.

If you’re in a state with time-of-use export rates like California’s NEM 3.0, the analysis gets more involved because the value of your exports depends on when you export, not just how much. That’s where a solar monitoring system with time-stamped production data becomes important.

The Battery Storage Angle

The shift away from full retail net metering is, functionally, a forced subsidy to battery manufacturers. When exports are valued at $0.07 instead of $0.30, storing that power at home and using it yourself suddenly makes more financial sense than sending it to the grid.

A Tesla Powerwall 3 currently retails around $9,000 before installation. Installed cost is typically $11,000 to $15,000 depending on your market. Under California’s NEM 3.0, the payback on storage has gotten short enough that EnergySage’s data shows California solar-plus-storage quotes are now under 10 years in many cases. That wasn’t true three years ago. Under NEM 2.0, adding storage made sense for backup power but not really for rate optimization.

Whether this is good or bad for homeowners depends on your perspective. Batteries do provide real value: backup power, peak-shaving, and more energy independence. But being pushed into a $12,000 purchase because your utility’s compensation rate changed feels different from choosing it freely.

Net metering policy is, at its core, a negotiation between what solar homeowners want and what utilities are willing to give, refereed by state regulators answering to both. The rules are changing faster than ever before, and the direction in most states is toward lower export compensation. That doesn’t mean solar is a bad deal. In most markets, it still pencils out well. But the version of solar that pays for itself mostly through grid exports is increasingly a thing of the past. Designing a system around self-consumption, ideally with storage, is becoming the smarter approach regardless of where you live.
