How Much Power Does Starlink Use? – Running It on Solar
Seventy-five to one hundred watts. That is the Starlink power consumption figure that surprises people who plan to hang a Starlink dish on a solar-powered pole at a remote site, because the radio and controller next to it might draw five. The dish runs all day and all night, so even a modest wattage adds up to a serious battery bank. Get the sizing wrong and the link dies on the third cloudy day, usually when you need it most. So how much power does Starlink use, and what does it take to run it on solar?
According to SpaceX's specification sheets, the Starlink Standard kit averages 75 to 100 watts and the Starlink Mini averages 25 to 40 watts. Running around the clock, that works out to roughly 1.8 to 2.4 kWh per day for the Standard kit and 0.6 to 1.0 kWh per day for the Mini.
To run a Standard kit on solar through short cloudy spells, plan on roughly a kilowatt or more of panels and several kilowatt-hours of battery, depending on your sunlight. The Mini, which accepts 12 to 48 volt DC input, needs far less and is often the better fit for solar sites.
How Much Power Does Each Starlink Kit Use?
The Starlink Standard kit specification sheet lists average power consumption of 75 to 100 W. The Mini kit specification sheet lists 25 to 40 W average, with a 12 to 48 V DC input rated at 60 W. Those are the numbers to design around, but check the sheet for your exact model, because hardware generations change.
To turn watts into energy, multiply by hours. Starlink power consumption for a full day looks like this:
- Mini, low end: 25 W × 24 h = 600 Wh (0.6 kWh) per day
- Mini, high end: 40 W × 24 h = 960 Wh (about 1.0 kWh) per day
- Standard, low end: 75 W × 24 h = 1,800 Wh (1.8 kWh) per day
- Standard, high end: 100 W × 24 h = 2,400 Wh (2.4 kWh) per day
The chart below puts those daily totals side by side.

Why Is Starlink's Draw Higher Than Other Field Radios?
A Starlink dish is a phased-array antenna. It steers its beam electronically to track satellites moving fast across the sky, and it does that constantly. That takes far more electronics than a fixed radio pointed at a tower.
Draw also moves around. Heavier data use, startup and snow-melt heating on models that offer it can raise consumption above the average. For sizing, I use the top of the listed range and then add margin. It is cheaper to buy one more panel than to send a truck to a site whose link quit before dawn.
Does Running Starlink on AC Waste Power?
Yes, a little. If your battery bank is DC and the kit expects AC, an inverter sits in between, and inverters lose energy. A small inverter might run around 85 to 95 percent efficient at its usual load, and it draws some power just sitting idle.
Here is the effect on a Standard kit at the high end:
- Load at the dish: 2,400 Wh per day
- Inverter at 90% efficiency: 2,400 ÷ 0.90 = about 2,670 Wh per day from the battery
That is roughly 270 extra watt-hours every day. The Mini's DC input avoids this loss on a 12, 24 or 48 V battery system, which is one reason it fits solar sites so well. Have a qualified technician confirm wiring, fusing and voltage limits for any DC installation.
How Big a Solar System Does Starlink Need?
Size for the worst month, not the average. The method is the same one used for any off-grid load: daily energy, divided by sun hours, adjusted for losses, then a battery big enough to ride through cloudy days.
Worked Example: Starlink Standard on Solar
Example inputs: 2,670 Wh per day from the battery (from the inverter math above), 3.5 worst-month peak sun hours, 75% overall system efficiency for wiring, charging, temperature and dirt, 3 days of autonomy and 80% usable battery depth of discharge.
- Array size: 2,670 ÷ (3.5 × 0.75) = about 1,017 W, so roughly 1,000 to 1,200 W of panels.
- Energy for autonomy: 2,670 × 3 days = 8,010 Wh.
- Battery size: 8,010 ÷ 0.80 = about 10,000 Wh, or 10 kWh of battery.
Worked Example: Starlink Mini on Solar
Example inputs: 960 Wh per day on DC with no inverter, the same 3.5 sun hours, 75% efficiency, 3 days of autonomy and 80% depth of discharge.
- Array size: 960 ÷ (3.5 × 0.75) = about 366 W, so a 400 W array.
- Energy for autonomy: 960 × 3 = 2,880 Wh.
- Battery size: 2,880 ÷ 0.80 = 3,600 Wh, or about 3.6 kWh.
The Mini needs roughly a third of the panels and battery. Try your own numbers in the calculator below, using your site's worst-month sun hours and the autonomy you need.
How Can You Cut Starlink Power Use at a Remote Site?
The easiest watt to supply is the one you never use. A few practical options:
- Pick the lower-power kit if its speed and coverage meet the site's needs.
- Run on DC where the hardware supports it, skipping inverter losses.
- Switch the terminal off on a schedule if the site only needs to report a few times a day, using a timer or the site controller to cycle power.
- Keep SCADA polling efficient, sending data by exception rather than streaming constantly.
- Keep a low-power backup path, such as cellular or radio, for critical alarms if the satellite link is off.
Scheduling has a trade-off. A dish that is powered off cannot receive commands, and it takes time to reconnect after power-up. For sites that need constant control, size the solar for continuous operation.
Where Does Starlink Fit in a Remote Site Power Plan?
On a small monitoring site, the satellite terminal is often the biggest electrical load, bigger than the RTU, radios and sensors combined. That makes it the item that drives your solar and battery size. On larger sites with pumps or compressors, there may already be a generator or utility drop, and the dish can run from that supply with a battery for ride-through.
If you are working out how the rest of the pad gets its electricity, our guide to oilfield power generation covers utility lines, gas gensets and solar for small loads.
Starlink Power Consumption, Sized for the Worst Week of Winter
Starlink power consumption runs about 75 to 100 W average for the Standard kit and 25 to 40 W for the Mini, per SpaceX's spec sheets. Across a day, that is roughly 1.8 to 2.4 kWh for the Standard and 0.6 to 1.0 kWh for the Mini.
For solar, design at the top of the range, add inverter losses if you run AC, and size for your worst month and several cloudy days. Then run your own numbers through the calculator and add margin. A link that stays up through a gray week is worth a few extra panels.
