In a winter storm outage, small solar add-ons help with the things that run on low power: light, phone charging, a radio and a few small devices. They do not heat a house, and winter sun is a weak, unreliable refill. Treat solar as a top-up for a kit you charge from the wall before the storm, not as the main plan.

This guide builds a small-household kit around that idea. It is deliberately not a whole-home backup design; for that, see our guide to solar kits for whole-home backup. It also quotes no wattages or runtimes, because they vary by product and the labels and manuals are the reliable source.

Start with the basic emergency kit

Ready.gov's basic emergency supply kit is a good baseline. It lists a battery-powered or hand-crank radio, a NOAA Weather Radio with tone alert, a flashlight, extra batteries, and a cell phone with chargers and a backup battery. It also recommends a sleeping bag or warm blanket for each person and a complete change of clothing suited to your climate.

Notice what that list is: information, light and warmth from clothing and bedding. Solar add-ons support the first two, since a radio, a flashlight and a phone all draw very little. They do not replace the third. If your plan depends on a power station to keep a space heater going, the plan needs rethinking.

What small solar can and cannot do

Small panels and portable stations are good at low-power jobs. Charging phones, running a few LED lights, powering a router for a short time and keeping a radio fed are all realistic uses. Heat-producing appliances, such as space heaters, kettles and hair dryers, generally draw far more than small gadgets, and a small system is usually the wrong tool for them.

Rather than quote numbers, use the labels. Every appliance has a rating plate. Every portable power station has an output rating and a capacity in its spec sheet. Compare the two, and if the appliance rating exceeds the station's stated output, do not plug it in. A plug-in watt meter, covered in our power station accessories guide, shows what your devices actually draw.

The add-ons that earn their place

Power banks

A fully charged power bank with the right cables is the lowest-effort backup for phones. Charge it from the wall before the storm, and keep it somewhere you can find in the dark. Some banks accept solar charging and some do not, so read the manual before counting on it.

A small power station and a folding panel

If you own a power station, a compatible folding panel can top it up on bright days. Match the panel's connector and electrical limits to the station's manual. Our portable panel guide covers the types, and the extension cable guide covers running a panel away from a snowy porch.

USB lights and a lantern

Rechargeable USB lanterns and string lights draw little and last. A few in different rooms are more useful than one bright light, and they cut the need for candles, which are a fire risk in an outage.

A radio that does not depend on the grid

A hand-crank or solar-assisted radio with a weather band backs up the NOAA radio Ready.gov lists. Check that it has a charging method that works without a power source, and test it before you need it.

Short, labeled cables

Pack a short cable for each device type you own, and label them. In the dark with cold fingers, a labeled pouch is a real advantage.

Winter changes the solar side

Winter days are short, the sun is low, and snow can cover a panel entirely. A snow-covered panel produces little until it is cleared, and clearing it has its own safety and damage risks; see our guide to clearing snow off solar panels. Our cold-weather performance guide explains why winter output is low even on a sunny day.

Cold also affects batteries. Lithium battery makers set low-temperature limits for charging, and those limits are in the manual. Keep stations and power banks indoors in the cold, and bring them in before charging from a panel outside if the manual says to. Do not leave the whole kit in an unheated car or porch and expect it to charge.

The practical rule is to charge everything fully from the wall while you still have power, then use solar to extend the run. That is a more honest plan than relying on a panel to rescue a flat battery in a storm.

Plan around the people in the house

A kit should reflect who lives with you. Households with young children, older relatives or pets need warmth and light in a few specific rooms, and a kit that is easy to find and use in the dark matters more than a clever one. Keep it in one labeled bin, with a printed card listing what is inside and how to start each item.

If anyone in the household depends on powered medical equipment, a small solar kit is not designed for that job. Talk to the equipment supplier and your utility about backup plans well before a storm, and do not rely on an improvised setup.

Think about communication too. Phones last longer with brightness turned down and unneeded apps closed, and a short text uses less power than a long call. Agree on a check-in plan with family before the weather arrives, so that power-saving does not become a worry.

Combustion and carbon monoxide

Solar add-ons make no fumes, but people sometimes reach for fuel-burning heat in an outage. The CDC's carbon monoxide guidance says never to run a generator inside your home or garage, even with doors and windows open, and to place generators outdoors away from windows, doors and vents. It also says not to burn charcoal indoors, not to use portable gas camp stoves or flameless chemical heaters indoors, and never to heat a home with a gas oven. The CDC recommends battery-operated or battery-backup carbon monoxide detectors near every sleeping area.

A battery-backup CO detector is a smart addition to an outage kit. Check its battery when you check your other kit items.

Test the kit before the storm

Do a dry run on a normal evening. Charge each device from its stored kit, run the lights, play the radio, and check that every cable fits. Write down what you learned, and replace anything that failed. Put a short card in the kit listing the station model, where its manual is stored, and the steps to switch it on.
