Having internet access is crucial these days, even when living off the grid. A solar powered Wi-Fi router allows you to stay connected without relying on the electrical grid. Building your own system is a great way to customize it to your needs and save money. Follow this guide to build your own solar powered Wi-Fi router for off-grid connectivity.

Gather the Necessary Components

The main components you'll need are:

Size the System Properly

When sizing your system, the two most important factors are the solar panel wattage and battery capacity.

The solar panel needs to provide enough power to run the router and charge the battery. 100W is a good starting point for most off-grid connectivity needs.

The battery capacity determines how long you can go without sun before losing power. For continuous operation, it should provide at least 3 days of power storage. A 100Ah battery gives a good safety margin.

Also make sure all components are compatible. The controller and inverter must be rated for the voltage and power output of the solar panel and battery.

Calculate Your Power Requirements

To properly size the system, you need to calculate your power requirements:

For example, a router using 8W continuously for 10 hours per day:

8W * 10 hours = 80Wh
80Wh * 1.2 (20% loss) = 96Wh per day

Size the panel and battery accordingly to provide at least this much power.

Wire the Components Together

With all the parts ready, it's time to wire them together:

Refer to the manufacturers' manuals for detailed wiring instructions. Diagrams are helpful to ensure proper connections.

Configure the Router

With everything connected, configure the router:

Thoroughly test the connectivity before deployment.

Install and Maintain the System

Once configured, it's time to install and maintain your off-grid network:

With proper installation and maintenance, your DIY solar router should provide reliable, renewable off-grid connectivity for years!

Troubleshooting Issues

If you encounter issues with your solar Wi-Fi router, here are some troubleshooting tips:

Pay close attention to the LED indicators on each component which can indicate issues. Start by verifying proper input voltage and loads at each stage in the system.


Creating your own solar powered Wi-Fi router takes some effort but provides a reliable, renewable connection while living off-grid. Carefully select the components to match your requirements and bandwidth needs. Follow the wiring diagram closely when linking everything together. With proper installation and occasional maintenance, the system should operate maintenance-free for years. Powering your networked devices from the sun brings freedom and possibilities, whether your goal is a remote office, IoT sensors, or streaming video in the wilderness.
