Immediate answer
Can solar power a Wi-Fi router?
Yes. A router is a low-power load, but a dependable connection may also require power for an fibre ONT, modem or network switch.
Because networking equipment often runs 24 hours a day, its daily watt-hours are more important than its low instantaneous wattage.

Choose an appliance
What do you want to power?
Search or choose a common appliance to get a practical starting point.
Results use typical appliance figures. Check the rating plate before buying equipment.
Why the answer varies
Often left on continuously; include any separate modem or mesh units. The database uses a 6–20 W range and a 6–20 W surge range. These are planning assumptions, not claims about every model.
What to check before buying
- Add every powered network device, not just the router.
- Check whether your broadband service continues during a local power cut.
- For backup use, prioritise automatic changeover and adequate overnight runtime.
Frequently asked questions
How much battery does a router need?
Multiply the measured combined wattage of the router and supporting equipment by the required hours, then include conversion losses and reserve.
Will solar keep broadband working in a power cut?
It can power your equipment, but the provider's street or exchange equipment must also remain operational.
