Solar Generator vs Gas Generator for Power Outages
A gas generator burns fuel and must run outdoors, at least 20 feet from doors, windows and vents, say CDC and Ready.gov. A solar generator is a battery power station with a fixed number of watt-hours. No agency page we read compares the two or states noise or running costs, so this page does not invent them.
What the sources can and cannot compare
The question "which one" has a long answer in most blogs. This page uses a stricter rule: it says only what a page we read states, with the source, and where no source compares the two, it says so. We read government pages on generator safety, fuel storage, food during outages and outage length. We read Jackery's pages for the battery side. We did not run either kind of machine.
| Criterion | Gas (fuel-burning) generator | Solar generator (battery power station) |
|---|---|---|
| Where it can run | Outdoors only; never indoors, in a garage, basement or shed (CPSC). At least 20 feet from doors, windows and vents (CDC and Ready.gov) | No agency page we read names battery power stations, so there is no agency rule to cite. Use the maker's manual |
| Fuel | Gasoline or another liquid fuel; CPSC says to store it in a well-ventilated, cool area, not inside a house or basement, away from flames and pilot lights, and out of children's reach | None burned. Charged from a wall outlet or panels; Jackery states recharge times that vary within its own pages |
| Carbon monoxide | CPSC says CO can kill in minutes and that one generator makes as much as "hundreds of cars"; keep a working CO alarm | No page we read says anything about a battery unit and CO. We do not claim it |
| How long it runs | No source read gives a runtime for a gas generator, and it depends on the tank | Set by watt-hours: capacity times our 85% assumption, divided by watts. 22.8 hours for a refrigerator average on a 2042 Wh unit |
| Noise | No agency page read states generator noise | No source read states a noise level for a power station |
| Running cost | No source read gives a fuel cost per hour | No source read gives a cost per charge. Jackery's purchase prices are on its pages |
| Compare directly | No agency page read compares generators with battery stations | Same |
Three rows are a plain "no source". That is deliberate. Noise and running cost are the figures that blog comparisons fill in with numbers, and we cannot attribute any to a page we read.
Safety: what the agencies say about fuel-burning generators
CPSC's generator page says to use a generator only outdoors, well away from windows, doors, vents or any other opening, and never indoors, in a garage, a basement or a shed. It says carbon monoxide can kill in minutes. CDC's toolkit pages say to keep the generator outside at least 20 feet away from any doors, windows or vents, and Ready.gov says at least 20 feet from windows, doors and attached garages. CPSC's generator page does not give a distance in feet, so the 20 feet figure is from CDC and Ready.gov.
Ready.gov adds that carbon monoxide detectors with battery backup belong on every level of the home. It also says to keep a generator dry, to use heavy-duty cords, to let it cool before refuelling, and not to heat a home with a gas stove or oven.
CPSC's page on fuel containers says to store fuel in well-ventilated, cool areas only, not inside a house or basement, away from fuel-burning appliances, flames and pilot lights, with the cap on and out of children's reach. It defines a portable fuel container as five gallons or less and says new cans need flame mitigation devices. Our file says that is a container definition, not a home storage limit, and local fire code controls quantity. Gasoline shelf life is not on that page.
None of those pages says anything about battery power stations. That absence is the reason this site does not write that agencies approve or condemn them. The battery side rests on the maker's pages and on lithium-battery guidance: the FAA says lithium-ion batteries can overheat in what it calls thermal runaway, including if they are damaged, overheated, wet or overcharged. Read the manual for placement, ventilation and temperature limits.
How long an outage lasts, and what that means for each
EIA's article dated 2025-12-01 reports that in 2024 the average US electricity customer had about 11 hours of interruptions, which is about 660 minutes on our arithmetic. Nearly 9 hours of that came from major events, and EIA says those events, which included Hurricanes Beryl, Helene and Milton, accounted for 80% of the hours. Interruptions not triggered by major events routinely average about two hours per year, EIA says. The national average was 1.5 interruptions in 2024, and the worst state, South Carolina, was nearly 53 hours.
These are averages across all customers, so they are not a prediction of any single outage. A household that lost power for a day in a storm and a household that lost it for ten minutes both sit inside the same average.
For a battery unit, outage length turns into arithmetic against watt-hours:
| Load | Explorer 300 (293 Wh) | Explorer 1000 v2 (1070 Wh) | Explorer 2000 v2 (2042 Wh) |
|---|---|---|---|
| Refrigerator, 76 W average | 3.3 hours | 12.0 hours | 22.8 hours |
| Wi-Fi router, 12 W | 20.8 hours | 75.8 hours | 144.6 hours |
| LED bulb, 10 W | 24.9 hours | 91.0 hours | 173.6 hours |
| Space heater, 1,500 W | over rated output | 36 minutes | 1.2 hours |
These are our run times at the 85% usable assumption, from the sizing method on what can a solar generator run. "Over rated output" means the load is above the unit's rated AC output, so that unit cannot run it. The fridge row is a 24-hour average, and startup draws more. FoodSafety.gov and Ready.gov say an unopened refrigerator keeps food safe for about 4 hours, and FoodSafety.gov says up to 48 hours for a full freezer and 24 hours for a half-full one.
For a fuel generator, no page we read gives a rated runtime or fuel use, so we cannot make a similar table. What the safety pages do say is that it must be refuelled after it cools, and that fuel must be stored properly. That is an ongoing task during a long outage, with a safety cost the agency pages describe at length.
Matching the source to the outage
On what the pages state, here is a reasonable way to think about the choice, and it is a framework, not a verdict:
- List what must run. Use the watts. A refrigerator, a router and lights are small loads and a battery handles them. Heating and cooking loads in the 1,500 W range are large, and a battery gives them minutes to an hour or two on the sizes above.
- Estimate how long. EIA's averages say most interruptions are short, with a long tail from major events. Your own area's history is better evidence than a national average.
- Check where it would sit. A fuel generator must be outdoors, 20 feet from openings. If you cannot place one that way, the question answers itself. A battery unit has no agency rule we can cite, so follow its manual.
- Weigh the recharge. A battery unit needs power to refill. Jackery's solar times vary within its own pages, and a long, cloudy outage is a different case from a short one.
- Do not rely on either for a medical device without asking its maker. Ready.gov says to talk to your medical provider about an outage plan for electric medical devices. This page gives no medical advice and does not say that any source of power will keep a medical device running.
No source we read ranks gas above solar or the reverse, and we do not either.
Which Jackery size, if you choose the battery route
On Jackery's own numbers, the Explorer 300 fits phones, lights and a router. The Explorer 1000 lineup is the middle size, and the Explorer 2000 suits a refrigerator through a longer outage. The Jackery review covers the maker, and head-to-head pages compare it with other brands: Jackery vs EcoFlow and Jackery vs Bluetti. Our best solar generator hub sets out the criteria. If the plan is a campsite rather than a house, see solar generator for camping and RV.
Power is only part of a plan. The 72-hour emergency kit checklist puts it beside water and food, and a bug out bag is the version you carry. For water during an outage, see the survival water filter hub. For food that needs no refrigerator, see survival food kits.
FAQ
Is a solar generator safer than a gas generator?
We cannot say. CPSC, CDC and Ready.gov publish rules for fuel-burning generators, including a 20 foot distance and never indoors. No agency page we read covers battery power stations, so there is no agency comparison to cite.
Which is quieter?
No source we read states noise levels for either kind, so this page gives no comparison.
Which costs less to run?
No source we read gives a fuel cost per hour or a cost per charge, so we give none.
Can I run a solar generator indoors?
No agency page we read addresses it. The 20 foot and never-indoors rules apply to fuel-burning generators. For a battery unit, follow the maker's manual.
How long do power outages last?
EIA reports about 11 hours of interruptions per customer on average in 2024, nearly 9 hours of it from major events. That is an average, not a forecast for your outage.
