🟠 The Summer Mining Tax
From an Avalon Q operator’s perspective.
Summer is the worst time to mine at home. Ambient temperatures climb, the miner has to work harder to dump heat, and any room that was tolerable in February turns into a sauna by July. It’s easy to just shut the machine off until October and wait it out.
That’s leaving sats on the table. A Canaan Avalon Q running in Eco mode is a genuinely workable summer setup. For home miners on sub 10¢ power, anyone with solar, and operators on commercial power agreements where demand charges and time of use rates reward a lower draw.
Here’s the case.
🟠 What Eco Mode Actually Does
The Avalon Q has three power modes:
▫️Eco at ~54 TH/s and ~800W
▫️Standard at ~80 TH/s and ~1,300W
▫️Super at ~90 TH/s and ~1,674W
The detail a lot of buyers miss is that Eco isn’t just lower output. It’s the most efficient mode the unit runs in. Eco delivers about 15.9 J/TH versus Super’s 18.6 J/TH.
You give up about 40% of the hashrate, but you cut the power draw by more than half, and you cut heat output proportionally.
That last part is what makes Eco a summer mode.
🟠 The Numbers at Sub-10¢ Power
At today’s (April 26, 2026) hashprice of around $36.46/PH/s, the daily math on Eco mode looks like this.
Revenue: 0.054 PH/s × $36.46 = ~$1.97/day.
Power at $0.09/kWh: 0.8 kW × 24h × $0.09 = $1.73/day.
Net: ~$0.24/day per unit.
Not a fortune. But positive. At $0.07/kWh — where a lot of solar supplemented and commercial contract operators sit, the same machine clears about $0.50/day, or roughly $15/month per unit.
Eco is profitable at 9¢ where Super is underwater. That’s the inversion a lot of miners haven’t internalized. A slower mode beats the flagship mode at moderate power rates.
🟠 Solar and Commercial Power Pairing
If you have a small residential array, the math gets even better. An 800W draw is something a 4–6 kWh/day solar contribution can meaningfully offset, especially in summer when production is highest and grid rates are highest.
A modest rooftop system can cover a real chunk of the daily load on Eco, and Eco fits inside the production envelope a lot of homeowners already have.
For operators on a commercial power agreement, Eco is often the smarter draw regardless of season. Many commercial tariffs include demand charges where you’re billed on your peak 15 minute draw across the month, not just total kWh.
Running Eco caps your demand at ~800W per unit instead of 1,674W.
Time of use contracts work the same way. Eco keeps you in lower rate tiers during peak afternoon hours, which is exactly when summer demand pricing hits hardest.
🟠 Why the Avalon Q Specifically
The reason this works on the Avalon Q is the way Canaan engineered it. It runs on 110V or 240V, the noise floor in Eco is 39–47 dB (quiet enough for a basement or utility room), and the three mode switching is built into the firmware.
You’re not undervolting an industrial unit — you’re using a designed mode.
If you’ve been thinking about adding a unit this summer, Altair Technology stocks the Avalon Q with US warranty support and 1 business day shipping.
Mining doesn’t stop in July. The setup just changes.
