With the recent licensing of Starlink in Zimbabwe, many are eager to explore how this satellite internet service can be integrated into their homes or businesses, especially in areas plagued by power outages or lacking traditional internet infrastructure. 

One of the critical questions is whether Starlink can be efficiently powered using solar energy. This article will delve into the details of Starlink’s power consumption, how to calculate the necessary solar power requirements, and provide practical tips for minimizing energy consumption.

How Much Power Does Starlink Use?

Starlink's power consumption is significantly higher than that of traditional internet modems. Here’s a breakdown of the power usage for different Starlink models:

  1. Starlink Mini: 5-10 watts in standby, 35-50 watts in active mode, and up to 65 watts at peak consumption.
  2. Starlink Standard: 10-20 watts in standby, 45-75 watts in active mode, and up to 100 watts at peak consumption.
  3. Starlink High-Performance: 15-30 watts in standby, 110-150 watts in active mode, and up to 180 watts at peak consumption.

For a typical user in Zimbabwe, the Starlink Standard kit is the most common choice, consuming between 45 to 75 watts during active use.

Can Starlink Run on Solar Energy?

Yes, Starlink can be powered with solar energy, but it requires careful planning to ensure the solar system can handle the load.

Example 1: A 3kW Solar System

To illustrate this, consider a scenario where you want to power a Starlink Standard kit along with other basic appliances.
Can You Power Starlink with Solar Energy - Sona Solar Zimbabwe Expert Advice
Can You Power Starlink with Solar Energy - Sona Solar Zimbabwe Expert Advice
Starlink Standard: Peak consumption of 100 watts for 16 hours equals 1600 watts.

Additional Appliances:

  • Laptop (10 hours/day): 500 watts
  • TV (4 hours/day): 800 watts
  • Fridge (continuous): 1200 watts
  • Lighting (10 bulbs at 10W for 5 hours): 500 watts
  • Total daily consumption would be approximately 4600 watts.

For this setup, a 3kW solar system would be a good starting point. Here’s what you would need:

  1. Solar Panels: 6 panels, each producing 300W, which would generate 9500 watts in 5 hours of peak sunshine.
  2. Battery: A 24V 100Ah battery to store approximately 2.4kWh, sufficient to power your Starlink and other appliances for several hours.
  3. Inverter: A 3kW inverter to handle peak power loads from multiple devices running simultaneously.

Example 2: Inverter and Battery Backup System

For a smaller setup, consider using a battery backup system.
  1. Battery: A 12V 100Ah lithium battery has 1200 watt-hours. Considering 80% usage, this leaves you with 816 watt-hours.
  2. Inverter: An inverter with an efficiency of 85-90% can provide enough power to run a Starlink Standard kit for at least 8 hours.

How to Calculate Solar Power Requirements

To determine the solar power requirements, you need to consider the total energy consumption of your Starlink and other appliances.

Calculate Daily Energy Consumption:

  1. Starlink Standard: 45-75 watts for 8 hours = 360-600 watt-hours.
  2. Other appliances: Calculate their individual energy consumption based on their wattage and usage hours.

Determine Solar Panel Capacity:

To cover the energy needs, you will need solar panels that can generate enough watt-hours in the available sunlight hours. For example, if you need 600 watt-hours, and you have 5 hours of peak sunlight, you would need solar panels capable of generating at least 120 watts (600 watt-hours / 5 hours).

Battery and Inverter Sizing:

Ensure your battery bank can store enough energy to cover nighttime or cloudy day usage. A lithium battery with a capacity of 500-1000 Ah is often recommended.

The inverter should be sized to handle the peak power requirements of your Starlink and other appliances. A 300-watt inverter or higher is typically sufficient.

Practical Examples and Case Studies


Case Study: Off-Grid Starlink Setup

A user in Idaho successfully ran a Starlink setup purely on solar energy using:
Solar Panels: Three 100-watt panels totaling 300 watts.

  1. Battery: A 450Ah battery bank.
  2. Inverter: A setup that allowed for 24/7 operation even in challenging weather conditions.

This example demonstrates that with the right solar panel and battery configuration, Starlink can be powered efficiently off-grid.

How to Minimise Starlink Energy Consumption

To optimize your solar power setup and reduce the strain on your batteries, here are some tips:

Optimise Installation

Ensure the Starlink dish is positioned optimally to avoid interference. A poor signal can increase power consumption as the dish works harder to maintain the connection.

Reduce Devices Connected to Starlink

Limit the number of devices connected to the Starlink Wi-Fi network. More devices mean more power is used to manage and distribute the connection.

Optimise Wi-Fi Settings

Adjust the Wi-Fi range and transmission power. Reducing the broadcast range to cover only your intended area can save power.

Frequently Asked Questions


Can Starlink Work Without Electricity?

No, Starlink requires a continuous power supply. However, you can use a battery system or a solar-charged battery to keep it running during power outages or in off-grid locations.

Can I Run Starlink Off an Inverter?

Yes, you can run Starlink off an inverter as long as the inverter is sized to handle the peak power requirements of the Starlink dish and router. A 300-watt inverter or higher is typically sufficient.

Solar Packages in Zimbabwe - A 3KVA Solar Panel System For The Zimbabwe Home!

A 3kVA Solar System is one of the most popular sized Residential Solar Systems in Zimbabwe. A 3KVA Solar Power System will generate approximately 12 units of electricity (called kilowatt-hours or kWhs) per day. As mentioned, this is about 2/3 of the electricity usage of a modest Zimbabwean home. At current pricing, you can expect to pay about $2,000.00USD for a good 3kVA Solar System installed on your roof.  Is 3kVA of Solar System Enough for a Home in Zimbabwe? The experts who deal in solar said that three kilowatts (kW) of a Solar Power System is enough for an average family of three to four people. But for a larger family or for running an AC at home, five to seven kilowatts of a solar system will be required. Back in 2014, a 1 kW solar system was sufficient for the efficient running of a home. But today given that inverter batteries are becoming more prevalent and popular, a 3kVA system is at least required. A 3kW solar system will generate 12 to 15 units per day of power which...
