APS Solar Export Rates 2026: How to Maximize Your Savings

When I first started looking at my own APS bills, I thought of the grid like a giant battery. I figured I’d "store" my extra noon sunshine there and take it back at night for free. Boy, was I wrong! APS uses what’s called a "Net Billing" system. This means they track every single kilowatt-hour. If your panels make power and you use it *right then* to run your AC or your pool pump, that's "free" energy. You saved the full retail price! But the second that power leaves your house and goes back to APS, its value drops by more than half. It’s like buying a loaf of bread for $4 but the store will only buy it back from you for $1.50.

This is why "Export Credits" shouldn't be your primary goal. In 2026, the real goal is to minimize what you export. I learned to "load shift" my life. I started running the dishwasher and the laundry at 11 AM when my panels were cranking out power. By doing that, I was using my $0.14 power for free instead of selling it for $0.06 and then buying it back later. It felt a little weird at first, like I was living my life around the sun, but once I saw the first bill, I was hooked. I wasn't just a customer anymore; I was a manager of my own little power plant.

The $0.062 rate might sound low, and honestly, it is compared to the "good old days." But it’s still money in your pocket! The key is to make sure your solar company isn't over-sizing your system based on export value. I’ve seen salespeople try to sell "200% offset" systems, promising huge credits. But if those credits are only worth 6 cents, you’re paying for panels that will take 20 years to pay for themselves. A smart APS system is sized to cover your real-time needs first, and that’s where the true savings live.

One thing that confuses a lot of folks in the Phoenix area is the "Tranche" system. Think of a Tranche like a waiting line. Every year, APS sets a certain amount of solar capacity for a specific export rate. Once that line is full, the rate drops for the next group of people. If you got in three years ago, you might be at 8 or 9 cents. If you’re getting in now, in 2026, you’re likely in the "Tranche 2025" or "Tranche 2026" group, which is currently around $0.062. This is why I always tell people: stop waiting! The rate isn't going to go *up* next year.

I almost missed out on a higher rate myself because I spent six months "thinking about it." By the time I signed my contract, the Tranche had shifted, and I lost about a half-cent on my export credit. It doesn't sound like much, but over 20 years, that’s thousands of dollars! The good news is that once you sign your interconnection agreement and your system is "placed in service," your rate is locked in for 10 years. You don't have to worry about APS lowering your specific credit next month just because they feel like it. You’ve got a contract.

This "10-year lock" is a huge part of your financial planning. It gives you a guaranteed floor for your savings. I’ve had friends who were worried that solar was a "gamble," but when I showed them the Tranche lock-in, they realized it’s actually more stable than the grid prices themselves. APS can change their retail rates whenever the regulators let them, but they can't change your export rate until your 10-year window is up. That’s a bit of a triumph for the "little guy" in my opinion.

If the export rate is $0.06 and the retail rate is $0.14, the "spread" is where you lose money. So, how do you beat the spread? You become a master of self-consumption. I treat it like a game now. I looked at my APS app and realized my biggest energy hog was the pool pump. I used to run it at night because I thought it was "quieter," but that was costing me a fortune! I switched it to run from 10 AM to 3 PM. Now, that pump is basically running on "free" solar juice. I’m not exporting that power for 6 cents; I’m saving the full 14 cents I would have paid APS. It’s a 130% increase in value just by flipping a timer!

Another trick I learned is "pre-cooling." During those brutal July days, I set my AC to 74 degrees starting at 10 AM while the sun is high. I "charge up" the house with cold air using my own solar power. Then, when the sun goes down and the APS peak rates kick in, my AC doesn't have to work nearly as hard. I’m essentially using the thermal mass of my house as a battery. It’s a bit of a tangent, I know, but it’s these little lifestyle tweaks that make the APS export rates irrelevant. If you don't export, the rate doesn't matter!

I also started looking at my "vampire loads"—things like the extra fridge in the garage or the home office setup. By shifting as much as possible to the daylight hours, I reduced my "grid dependency" by almost 40%. It’s a great feeling to check the app at noon and see that 100% of my house is being powered by the roof, with nothing going back to the utility. That is the ultimate goal for any APS customer in 2026. Use it or lose it (well, lose about half the value of it, anyway).

This is the million-dollar question I get asked at every backyard BBQ. "Do I *have* to get a battery?" The honest answer is no, you don't *have* to. You can still save money with a panel-only system if you're diligent about your usage. But—and this is a big but—a battery is what makes the APS system "bulletproof." Without a battery, you are always going to be at the mercy of the export rate once the sun goes down. With a battery, the $0.062 rate becomes almost meaningless because you're storing that extra noon power and using it yourself at 7 PM.

I finally bit the bullet and added a battery last year, and it changed everything. Before the battery, I was still getting $80 or $90 APS bills because I couldn't avoid those evening peak charges. Now? My bill is basically the $30 connection fee. The battery takes that "low value" export power and turns it into "high value" evening power. It’s the ultimate arbitrage. Plus, I don't have to worry about "load shifting" my laundry anymore. I can do it whenever I want because I know I’ve got a tank full of sunshine waiting in the garage.

For most APS customers in 2026, I recommend at least a "battery-ready" system. Even if you don't buy the battery on day one, make sure your inverter and your electrical panel are ready for it. APS is only going to make it harder to save money with export-only systems in the future. By having a battery, you are opting out of their game entirely. You become your own utility company, and that is a very powerful position to be in when you live in a state where the sun is your biggest resource.
