Power outages aren’t getting shorter. The average U.S. customer lost about 11 hours to power interruptions in 2024, the U.S. Energy Information Administration reports, nearly double the yearly average from the decade before.
A gas generator can bridge that gap. So can a solar generator, minus the fumes, the noise, and the trips to the gas station.
But “solar generator” gets thrown around loosely. Plenty of listings use the term for a battery that’s never seen a solar panel. We only recommend kits here that actually pair a power station with real solar input, and we picked them based on how fast they recharge from the sun, not just how big the battery is.

What Is a Solar Generator, Exactly?
A solar generator is a portable power station connected to one or more solar panels, so the battery recharges from sunlight instead of only a wall outlet. EcoFlow’s own breakdown of the two categories puts it simply: a power station stores energy, a solar generator actively makes it.
That distinction matters more than marketing copy suggests. A power station without panels is just a big rechargeable battery. It’ll get you through an outage once, then it’s dead until you find an outlet.
Add solar panels and the equation changes. As long as the sun’s out, you’re topping the battery back up. That’s the real value of a solar generator over a gas generator: you’re not driving anywhere for fuel.
Jackery’s guide to the difference between a solar generator, a power station, and a solar panel makes the same point: if you buy a power station and solar panels separately, you’ve built a solar generator setup yourself. Buying a kit just bundles the two so you don’t have to match specs on your own.
What Size Solar Generator Do You Need?
Match the battery to what you actually plan to run, not the biggest number you can afford. A 1,000 to 2,000Wh battery covers phones, a router, some lights, and a mini fridge through a short outage. Anything bigger, especially a full-size fridge or a window AC unit, needs 2,000Wh or more.
Two numbers decide what a solar generator can do for you: watt-hours (Wh) and watts (W). Watt-hours are the fuel tank, they tell you how long the battery lasts. Watts are the engine, they tell you what you can plug in at once without tripping the inverter.
Running a full-size fridge at roughly 150W alongside internet and a few lights drains a 2,000Wh battery in about 10 to 20 hours. If you want to see exactly what your gear would pull from one of these, our breakdown of what a portable power station can actually run walks through real appliance math.
Best Solar Generators of 2026
These five kits cover the range from weekend camping to keeping the lights on through a multi-day outage. All of them ship with, or offer, real solar panels rated for meaningful input wattage, not a token 30W trickle charger.
1. Jackery Solar Generator 2000 Plus Kit (Best Overall)
This kit pairs the Explorer 2000 Plus with two SolarSaga 200W panels. The battery starts at 2,042Wh and expands to 12kWh with add-on packs, which is enough headroom to grow from “backup for a few rooms” to “backup for most of the house” without replacing the unit. It handles up to 6,000W of combined output in parallel setups and takes solar input up to 400W across the two panels.
2. EcoFlow DELTA Pro 3 Solar Kit (Best for Whole-Home Backup)
The DELTA Pro 3 solar kit is built for people who want a real alternative to a whole-home generator. It holds 4,096Wh out of the box, expands to 48kWh, and outputs 4,000W (6,000W with X-Boost). Its solar input tops out at 2,600W across two MPPT ports, with 99% tracking efficiency, so it recharges faster from the sun than most home-backup units on the market.
3. BLUETTI AC200L + SP200L Kit (Best Value)
The AC200L solar kit lands in the middle of the pack on price for what it delivers: 2,048Wh of storage, 2,400W of output, and up to 1,200W of solar input. That input number is the story here. It’ll pull a full recharge from the sun in a fraction of the time a similarly sized unit with a 200W or 300W solar cap would need. It also expands to 8,192Wh if you outgrow the base unit.
4. BLUETTI AC180 Solar Kit (Best Budget)
For readers who want real solar charging without the flagship price tag, the AC180 pairs a 1,152Wh battery with up to 500W of solar input, which is generous for this size class. Add a 200W panel and you’re looking at a recharge window well under 10 hours in decent sun, according to BLUETTI’s own charging figures.
5. Jackery Solar Generator 1000 v2 (Best for Camping and Portability)
The Solar Generator 1000 v2 kit is built around Jackery’s smaller Explorer 1000 v2, which weighs under 24 pounds and hits a 1-hour fast charge from AC power. It still takes up to 400W of solar input, so a couple of hours of good sun gets you most of the way back to full. If your use case leans more toward camping trips than outages, this is the pick to start with.
How Fast Do Solar Panels Actually Recharge These?
Charging time from solar comes down to three things: panel wattage, hours of direct sun, and how efficient the built-in charge controller is. Most solar generators worth buying use MPPT (maximum power point tracking) controllers, which pull up to 25% more usable power from the same panels than older PWM controllers.
As a rough rule of thumb, aim for solar wattage that can refill your battery in 5 to 6 hours of peak sun. A 2,000Wh battery pairs well with 400 to 500W of panels. Undersize the panels and you’ll be waiting two or three days for a full charge instead of one afternoon.
Cloud cover, panel angle, and time of year all cut into that number too. Treat manufacturer charge-time estimates as a best case, not a guarantee.
Solar Generator vs. Gas Generator for Outages
A solar generator wins on convenience and safety for most home backup needs. It produces no carbon monoxide, so it’s safe to run indoors, and it’s quiet enough to sit next to while you sleep. A gas generator needs to run outdoors, needs fuel you have to store and rotate, and needs maintenance to start reliably when you actually need it.
Where gas still wins: raw output for whole-house loads like central air, and the ability to refuel instantly at 2 a.m. instead of waiting for daylight. If you’re weighing the two head to head, our full solar generator vs. gas generator comparisonbreaks down the tradeoffs in more detail.
For camping specifically, the calculus tilts even further toward solar. No fuel to haul, no fumes near the tent, and panels that do double duty charging phones and running a cooler during the day.
Do You Need the Home Backup Size or the Portable Size?
If your goal is keeping a fridge, router, and a few lights running through a multi-day outage, you want the 2,000Wh-plus tier, closer to the DELTA Pro 3 or AC200L in this list. Our full home backup power station picks go deeper on sizing a system for that use case specifically.
If you mainly need something for weekend trips, tailgating, or a laptop and phone during a shorter outage, the smaller kits like the Jackery 1000 v2 or the AC180 make more sense. Don’t pay for capacity you won’t use. If budget is the deciding factor over sizing, our power stations under $500 roundup covers the entry-level tier without solar bundled in, useful if you want to add panels separately later.
Is a Solar Generator Worth It?
For most homeowners in outage-prone areas, yes. The upfront cost is higher than a comparable gas generator, but there’s no ongoing fuel cost, no annual maintenance visit, and no carbon monoxide risk. Over a few years of outages, that gap narrows fast.
The honest caveat: a solar generator won’t run central air or a well pump for days on end the way a whole-home gas or propane system can. It’s built for the “keep the essentials running comfortably” tier of backup, not total energy independence. For most households, that’s exactly the gap that needs filling.
If you’re deciding between EcoFlow, Jackery, and BLUETTI specifically, our EcoFlow vs. Jackery vs. BLUETTI comparison breaks down how the three brands differ beyond just this list.
Pick the size that matches what you actually need to run, check that the solar input watts match your panel setup, and you’ll have a system that earns its keep the next time the grid goes down.
Frequently Asked Questions
Can a solar generator power a whole house?
A large unit like the EcoFlow DELTA Pro 3, especially when expanded with extra battery packs, can cover most essential circuits during an outage. It won’t run everything at once the way a whole-home standby generator does, but it can keep a fridge, lights, internet, and small appliances running for days.
How long do solar generators last?
Most current models use LiFePO4 batteries, which are rated for thousands of charge cycles, often 3,000 to 4,500 depending on the brand, before capacity drops meaningfully. Used a few times a year for backup, that translates to well over a decade of useful life.
Do I need special solar panels, or will any panel work?
You need a panel that matches your unit’s voltage and connector type, or you’ll need an adapter. Manufacturer-matched panels (Jackery SolarSaga, EcoFlow’s own panels, BLUETTI’s PV series) are the safest bet since they’re tuned for that unit’s MPPT controller and won’t need extra troubleshooting.
Is a solar generator worth it over a gas generator?
For most homeowners dealing with occasional outages, yes. You skip the fuel storage, the noise, and the carbon monoxide risk, and you can run it indoors. Gas still wins if you need to power heavy whole-house loads like central air for extended periods.
Can a solar generator charge on a cloudy day?
Yes, but slower. Solar panels still produce power in overcast conditions, typically 10 to 25% of their rated output, so a charge that takes 5 hours in full sun might take most of a day under heavy cloud cover.
