Better A/C, powered by the sun
Peak Cool hybrid solar mini splits run on solar power during the day, while the panels are producing, cutting your biggest energy expense in real time. When the sun goes down, they switch to grid power on their own. No batteries, no interruption, and now in ductless or ducted systems.

Grid power: the hidden tax on cooling
Fighting 110°F heat on the grid is expensive. Here's what a standard 2-ton (24,000 BTU) mini split costs to run in an Arizona summer on SRP and APS time-of-use rates.
| Metric | Standard 2-ton On the grid | Photon AC 2-ton On the sun |
|---|---|---|
| Average power draw on a 110°F afternoon | 1.5 – 1.8 kW | From its own panels |
| Cost per hour during the 4–7 pm peak | $0.39 – $0.62 | $0.00 |
| Summer month (10 daytime hours a day) | $55 – $90 | $0.00 |
| One cooling season (May–October) | $340 – $540 | $0.00 |
| 10 years, with rates rising 3% a year | $3,900 – $6,200 | $0.00 |
Photon AC figures are for the hours it runs on the sun. How we figured it: 1.5–1.8 kW average draw on 105–115°F days, 10 daytime hours a day with 2 in the 4–7 pm peak, summer rates of about 9–12¢ off-peak and 26–34¢ on-peak (SRP E-26 and APS 4–7 pm plans), a May to October season, and rates rising 3% a year. Your plan, home and thermostat will change the numbers.
Figures are calculated estimates and individual results may vary.
Do the math with your own bill
Every air conditioner has two prices: what you pay to buy it and what you pay to run it. Plug in your own bills to see what the second one is costing you.
One unit in the main living area carries the daytime load. More units or a ducted system carry more.
Heating and cooling come to about $2,070 a year on your bills (6 summer months at $300 plus 6 winter months at $45).
- One year
- $518
- Five years
- $2,747
- Ten years
- $5,933
Estimate only, not a guarantee. Five and ten years assume rates rise 3% a year. Real results depend on sizing, panel count, roof direction and shade, thermostat settings and your utility plan.

How hybrid solar AC takes daytime air conditioning off your power bill: how it works, what it saves, and what your install looks like.
You're already paying for this system. You just don't own it yet.
That money leaves your account every month either way. The question is whether it goes to the utility forever, or toward an asset on your home that pays you back.
Money to the utility
a month every summer, depending on home size and thermostat setting
- 50–70% of your power bill is AC alone (varies by season).
- The lower the thermostat, the bigger the check to the utility.
- No equity, no asset, and rates keep going up.
Same money to a Photon AC
You're already spending it. Now it builds an asset on your home.
- Cuts the biggest line item on your bill: daytime AC.
- Power-bill savings plus less wear on your central AC help cover the monthly payment.
- Adds value to your home. The utility never will.
Pay cash
Savings start day one. You skip peak-hour utility costs and keep that money every month from here on out.
Finance it
Whether it's one room or the whole home, what you save on your power bill and on wear to your central AC typically covers the monthly payment. Financing is through Wisetack.
That money is leaving your bank account every month either way.
Rent your cooling from the utility forever, or put it toward an asset that lowers your bills.
Why solar AC beats standard solar
Four reasons direct-power solar AC is the faster, higher-return choice, without the red tape of a whole-home array.
No utility paperwork
Standard solar ties into the utility: permits, Permission to Operate and net-metering paperwork before you can flip the switch.
Solar AC plugs into its own panels, not the grid, so it starts saving as soon as it's installed.
Go after the energy hog
Up to 60% of a summer bill is the AC alone. A whole-home array to cover it can run $40,000.
Attack the biggest line item directly, for most of the savings at a fraction of the cost.
Peak power at peak heat
Utilities charge the most in the afternoon, exactly when your AC is working hardest.
Run on the sun when rates are highest. That's real peak shaving.
Soft start
Standard ACs slam on with a surge up to 5x their running wattage, spiking your meter and wearing out equipment.
Variable-speed DC compressors ramp up smoothly. No flicker, no spike, no thump.
Where Photon AC fits
One system, lots of places to put it to work.
Homes
Cool living rooms and bedrooms on solar power and cut the biggest part of your summer bill.
Garages
Turn a hot garage into a usable space for a home gym, workshop or hobby room.
Offices
Keep a workspace cool while cutting overhead. A practical upgrade for a business.
Trailers & RVs
Run AC off the sun on the road and save your battery bank for everything else.
ADUs
Cool a guest house without the expense of an electrical panel upgrade.
Off grid
Reliable cooling for remote cabins, tiny homes and places power lines don't reach.
Cool the whole house
Start with the room that runs hottest, or do them all. The more rooms you add, the bigger the discount: the crew is already on site, it's one truck roll, and bulk unit pricing kicks in. Ducted systems cover several rooms from one unit.
