How much power does Starlink actually use?

The watts, the monthly electricity cost, and the solar panel size you need to run it off-grid. Real numbers, not marketing.

The headline numbers

The Standard Starlink kit draws roughly 50 to 75 watts continuously, with peaks around 130 watts when the built-in dish heater runs in cold weather. The Mini draws roughly 25 to 40 watts continuously, with real-world tests after the January 2026 firmware update showing closer to 20 to 30 watts in steady use. The Mini does not have a snow-melt heater, so its draw stays in this range year-round. Both dishes are low enough to run off solar without much trouble, and high enough that a long off-grid setup needs real planning.

Monthly electricity cost (grid-tied)

If your dish runs 24/7 on grid power, here is what it costs at typical 2026 US electricity rates:

For most US households, this is about the same as running a refrigerator full-time. Annual cost is $40 to $115 depending on dish and climate. Not zero, but not significant in the context of a $960+ annual service bill.

In high-electricity regions (California, Hawaii, parts of Europe), multiply these numbers by 2 to 3x. A Standard dish running 24/7 in Germany at €0.40/kWh costs roughly €30 per month in electricity, which starts to matter.

Off-grid: how much solar do you need

The math gets more interesting off-grid because you need enough solar to cover the dish even on cloudy days, plus battery storage for nighttime use.

Mini, off-grid sizing

• Daily energy use: ~720 to 960 watt-hours per day (average to heavy use)
• Solar panel size (sunny climate, 6 hours peak sun): ~150 W panel covers it
• Solar panel size (cloudy climate, 3 hours peak sun): ~300 W panel needed
• Battery for one cloudy day: ~80 Ah at 12V (1 kWh)
• Battery for two cloudy days: ~160 Ah at 12V (2 kWh)

Standard, off-grid sizing

• Daily energy use: ~1.4 to 1.8 kWh per day
• Solar panel size (sunny): ~300 W panel
• Solar panel size (cloudy): ~600 W panel
• Battery for one cloudy day: ~150 Ah at 12V (~2 kWh)
• Battery for two cloudy days: ~300 Ah at 12V (~4 kWh)

The Standard's higher draw means roughly twice the solar and battery capacity. This is a real cost difference: $300 to $1,000 in additional solar and battery hardware to run the Standard versus the Mini off-grid.

For most off-grid setups (cabins, vans, RVs, boats), this is a strong argument for the Mini even though it costs less hardware up front. The total cost of ownership tilts further in the Mini's favor when you factor in solar and battery sizing.

Power-saving tactics

Cycle the dish on and off

If you do not need internet 24/7, turn the dish off during periods you are not using it. The Mini boots up in about a minute, the Standard takes 2 to 5 minutes. For most casual users (a few hours of evening internet), running the dish only when needed cuts power use by 50 to 75 percent.

A simple smart plug or 12V switch makes this trivial. Some setups use a motion sensor or schedule.

Use the Mini for off-grid

The single best power-saving tactic is just buying the Mini instead of the Standard for off-grid use. Lower draw, lower power infrastructure cost, lower total cost over the life of the dish.

Avoid running the heater unnecessarily (Standard only)

On the Standard dish, the heater runs automatically when snow accumulates. In some cases (the dish is parked in a heated garage between uses, or covered manually) you can avoid the heater cycles entirely. Saves significant power in winter. The Mini has no heater, so this does not apply, but its lower base draw makes off-grid power easier overall.

Run during peak solar hours

If your battery bank is small, schedule heavy internet use (large downloads, video streaming) during peak solar hours when you have surplus generation, and idle during evening when you are running on battery.

The honest verdict

For grid-tied users, Starlink power consumption is barely worth thinking about. Add $5 to $10 per month to your bill and move on. For off-grid users, it is a real factor but very manageable: the Mini runs comfortably on a 200 W solar panel and a 100 Ah battery for typical use, total cost maybe $400 in additional gear. The Standard needs roughly double that.

Either way, Starlink uses less power than a refrigerator and far less than electric heating or air conditioning. For the connectivity it provides, the energy cost is reasonable.
