Brands love to print things like “0 to 100% in as fast as 1.5 hours” for solar. That’s usually the best possible case: maximum panel watts, perfect sun, perfect angle. Your backyard in November may have other plans. Let’s work out a realistic number.

The one-line formula

Hours ≈ Wh ÷ (min(panel W, max solar input) × 0.7)

• Wh is your battery capacity (on the spec sheet).
• Panel W is the total rated watts of your panels. If it’s more than your unit accepts, use the unit’s max instead.
• 0.7 is our planning factor. Panels rarely deliver their full rated watts because of heat, angle, dust and conversion losses. Some days you’ll beat it, some days you won’t.

Estimated hours for popular models

Model	Capacity	Max solar	100 W	200 W	400 W	800 W	At max input
EcoFlow RIVER 3 Plus	286 Wh	220 W	4.1 h	2.0 h	1.9 h	1.9 h	1.9 h
Jackery Explorer 1000 v2	1,070 Wh	400 W	15.3 h	7.6 h	3.8 h	3.8 h	3.8 h
EcoFlow DELTA 3 Plus	1,024 Wh	1,000 W	14.6 h	7.3 h	3.7 h	1.8 h	1.5 h
BLUETTI AC180	1,152 Wh	500 W	16.5 h	8.2 h	4.1 h	3.3 h	3.3 h
Anker SOLIX C2000 Gen 2	2,048 Wh	800 W	29.3 h	14.6 h	7.3 h	3.7 h	3.7 h
EcoFlow DELTA 2 Max	2,048 Wh	1,000 W	29.3 h	14.6 h	7.3 h	3.7 h	2.9 h
Jackery HomePower 3000	3,072 Wh	1,000 W	43.9 h	21.9 h	11.0 h	5.5 h	4.4 h

Hours of strong sun, empty to full, calculated. Units with two solar ports (DELTA 3 Plus, DELTA 2 Max) need the panels split across both ports to go past 500 W. Every unit also has voltage and current limits; see the panel pairing guide.

From “hours” to “days”

Divide by the strong-sun hours you get per day. If you get about 5:

• Explorer 1000 v2 with 200 W: 7.6 ÷ 5 ≈ 1.5 days.
• DELTA 2 Max with 400 W: 7.3 ÷ 5 ≈ 1.5 days.
• HomePower 3000 with 800 W: 5.5 ÷ 5 ≈ about a day.

Strong-sun hours vary a lot by location and season. Winter days are shorter and the sun sits lower. For your area, NREL’s free PVWatts tool can estimate solar output.

Weather: the big wildcard

Clouds can cut panel output sharply, and heavy overcast can drop it to a small fraction of the rated watts. Our calculator uses simple weather multipliers so you can see the swing. They’re rough planning guesses, not measurements.

Charging while using power

If the fridge is drawing power while the sun shines, your solar covers the fridge first and only the leftover goes into the battery. For example, 400 W of panels × 0.7 ≈ 280 W, minus a fridge averaging about 60 W, leaves about 220 W for charging. This is why solar makes a big difference in the Blackout Survival Challenge: flip on the solar option and watch your survival time jump.

Tips for faster solar charging

1. Aim at the sun and re-angle a couple of times a day.
2. No shade. Even partial shade can tank a panel’s output.
3. Keep the power station cool and out of direct sun. Batteries often charge more slowly when hot.
4. Match the input. Panels that add up close to your unit’s max solar watts (and stay within its voltage limits) give the fastest charging.

Bottom line

Use Wh ÷ (panel W × 0.7), then divide by your daily sun hours, and add a cushion for clouds. Do it in two taps with the Solar Charge Time Calculator, see bundle deals in best solar generator kits, and plan your loads with the runtime calculator.

Panels and power stations are like phone chargers: almost everything looks like it should fit, but the right match charges fast and the wrong one does nothing (or worse). Here’s a brand-by-brand cheat sheet.

The series-wiring sanity check

Panels in series add their voltages. Two EcoFlow NextGen 220W panels (21.5 V open-circuit each, per EcoFlow) come to about 43 V. That’s safely inside an 11 to 60 V window. Three would be about 64.5 V, which is over 60 V. Open-circuit voltage also rises in cold weather, so leave some headroom.

EcoFlow

Power station	Max solar	Voltage / current (per EcoFlow)
RIVER 3 Plus	220 W
DELTA 3	500 W	11 to 60 V
DELTA 3 Plus	1,000 W (2 × 500 W ports)	11 to 60 V per port
DELTA 2 Max	1,000 W (500 W per port)	11 to 60 V, 15 A
DELTA Pro 3	2,600 W	High-V port 30 to 150 V, 15 A, 1,600 W; low-V port 11 to 60 V, 20 A, 1,000 W

Official EcoFlow panels (connector: XT60/XT60i input cable):

Panel	Price (Oct 16)	Open-circuit voltage
100W Rigid	$139	20.3 V
NextGen 220W Bifacial	$399	21.5 V
400W Portable	$599

Match-ups: a single 220W panel suits the RIVER 3 Plus (its 220 W cap) or a DELTA 3. One 400W panel per port is a nice fit on a DELTA 3 Plus or DELTA 2 Max (each port caps at 500 W). On the RIVER 3 Plus our database’s notes didn’t confirm a solar voltage window, so check the manual first.

Jackery

Power station	Max solar	Working voltage / current (per Jackery)
Explorer 1000 v2	400 W	2 × DC8020: 12 to 16 V at 8 A; 16 to 60 V at 10.5 A (21 A / 400 W combined)
Explorer 2000 v2	400 W	11 to 16 V at 8 A; 16 to 60 V at 12 A (21 A / 400 W combined)
Explorer 2000 Plus	1,400 W	17.5 to 60 V at 12 A per port (24 A / 1,400 W combined)
HomePower 3000	1,000 W	12 to 16 V at 8 A; 16 to 60 V at 12 A (24 A / 1,000 W combined)

Official Jackery panels (connector: DC8020; some models need a DC8020-to-DC7909 adapter, which Jackery includes with certain panels):

Panel	Price (Oct 16)	Open-circuit voltage
SolarSaga 100 Prime	$199
SolarSaga 200W	$379	22 V
SolarSaga 500 X	$799

Match-ups: the Explorer 1000 v2 and 2000 v2 both cap at 400 W, so two SolarSaga 200W panels max them out. A 500 X on those units won’t charge faster than 400 W. The HomePower 3000 (1,000 W) and Explorer 2000 Plus (1,400 W) are where the 500 X makes sense.

BLUETTI

Power station	Max solar	Voltage / current (per BLUETTI)
AC180	500 W	12 to 60 V open-circuit, 10 A
Elite 100 V2	1,000 W	12 to 60 V, 20 A
Elite 200 V2	1,000 W

Official BLUETTI panels (MC4 leads; BLUETTI lists MC4 and Anderson/XT60 adapters by model):

Panel	Price (Oct 16)	Open-circuit voltage
SP100L 100W	$249	24.62 V
200W Portable	$399	24.6 V
350W	$649	44 V
500W (SORA 500)	$849	49.1 V

Match-ups: an AC180 tops out at 500 W and 60 V. One 350W panel (44 V) fits; two 350W panels in series (about 88 V) would not. Two 200W panels in series come to about 49 V, which fits. On an Elite 100 V2, two 200W panels in series plus the 20 A limit leave lots of room; check BLUETTI’s manual for parallel setups.

Anker SOLIX

Power station	Max solar	Voltage / current (per Anker)
C1000	600 W	11 to 60 V, 12.5 A (XT-60)
C2000 Gen 2	800 W	11 to 60 V, 17 A (XT-60i)
F3800 Plus	3,200 W (2 × 1,600 W)	11 to 165 V, 17 A per input

Official Anker SOLIX panels (XT-60i connector):

Panel	Price shown (Oct 16)	Open-circuit voltage
PS100 Bifacial	$249.99
PS200 Bifacial	$499.99
PS400 Bifacial	$699.99

Match-ups: a PS400 is a natural single-panel match for the C1000 (600 W cap) or C2000 Gen 2 (800 W cap; two PS400s max it on paper). The F3800 Plus’s wide 11 to 165 V window allows longer series strings, but follow Anker’s manual for exact configurations.

Bottom line

Same brand = least drama. Third-party = check watts, volts, amps and the plug. For charge-time math, try our Solar Charge Time Calculator, read how long it takes to charge with solar, or see bundled deals in best solar generator kits. All base specs live in the spec database.

Buying a power station and panels separately is like buying a burger and fries separately. Totally allowed. Usually more expensive than the combo. Here are the combos.

The kits at a glance

Kit	Kit price	Separately	Battery	Panel watts vs unit’s max solar	Est. hours of strong sun, 0 to 100%*
Jackery Explorer 1000 v2 + SolarSaga 200W	$719	$898	1,070 Wh	200 W of 400 W	~7.6
EcoFlow DELTA 3 Plus + 220W	$919	$1,118	1,024 Wh	220 W of 1,000 W	~6.6
EcoFlow DELTA 3 Plus + 2 × 220W	$1,069	$1,488	1,024 Wh	440 W of 1,000 W	~3.3
EcoFlow DELTA 3 Plus + 400W	$1,119	$1,318	1,024 Wh	400 W of 1,000 W	~3.7
Jackery Explorer 2000 v2 + 2 × SolarSaga 200W	$1,399	$1,657	2,042 Wh	400 W of 400 W	~7.3
Jackery HomePower 3000 + 2 × SolarSaga 200W	$1,799	$2,107	3,072 Wh	400 W of 1,000 W	~11.0
Jackery HomePower 3000 + SolarSaga 500 X	$1,899	$2,148	3,072 Wh	500 W of 1,000 W	~8.8
EcoFlow DELTA Pro 3 + 400W	$3,099	$3,398	4,096 Wh	400 W of 2,600 W	~14.6

*Hours ≈ Wh ÷ (panel watts, capped at the unit’s max, × 0.7). The 0.7 is our planning factor for real-world losses. At ~5 strong-sun hours a day, divide by 5 to get days. “Separately” = standalone station price + standalone panel price on each brand’s store, Oct 16, 2026 (Jackery 1000 v2 in Dune White; the black version was $20 cheaper). One oddity: EcoFlow’s DELTA 3 Plus kit page showed a “compare at” price below the sale price; we used the listed sale price.

Our picks

Best starter: Jackery Explorer 1000 v2 + SolarSaga 200W

At 23.8 lb, the Explorer 1000 v2 is the lightest ~1 kWh unit in our database, and the kit saves about $179. One 200W panel only uses half of the 400 W solar input, so budget for a second panel if you want faster refills.

Best mid-size: EcoFlow DELTA 3 Plus + 2 × 220W

The DELTA 3 Plus takes up to 1,000 W of solar over two 500 W ports, so it has lots of room to grow. Two 220W bifacial panels make for a fast, roughly half-day recharge on a good day (estimate).

Best for big home backup: Jackery HomePower 3000 kits

3,072 Wh with 1,000 W of solar input. The 2 × 200W kit is the better deal, while the 500 X kit uses one big panel instead of two. Either way you’re using half the input or less, so there’s room to add panels later.

Go big: EcoFlow DELTA Pro 3 + 400W

4,096 Wh and a whopping 2,600 W of solar input. One 400W panel barely scratches that input, so think of it as a starter panel.

The match-up trap (Jackery Explorer 2000 v2 + 500W)

Jackery also sells the Explorer 2000 v2 with a “SolarSaga 500W” option ($1,499). Since the 2000 v2’s solar input caps at 400 W, a 500W panel won’t charge it any faster than 400 W. It can help on hazy days, but don’t pay extra expecting speed.

What about BLUETTI and Anker SOLIX kits?

Both brands sell bundles too. Anker SOLIX lists combos like C1000 + PS400 and C2000 Gen 2 with 400W panels, and BLUETTI sells its own solar generator bundles. We couldn’t confirm stable bundle prices on their official stores on our check date, so they’re not in the table. To build your own, see the panel lists in our panel pairing guide.

Bottom line

A kit is usually the cheapest way in, as long as the panels fit the unit’s solar limits. Plug any combo into the Solar Charge Time Calculator, check daily needs with the runtime calculator, and compare units in the spec database.

Solar is where a power station goes from “nice battery” to “tiny power plant.” The sun shows up for free every morning, and with the right panels, so does your power. Let’s get your pairing right the first time.

The three numbers that matter

Think of it like a garden hose:

• Watts = how much water flows. Your power station has a maximum solar input in watts.
• Volts = water pressure. Too much pressure bursts the hose. Every unit has a solar voltage range, and exceeding the top end can damage it.
• Amps = the width of the hose. There’s a current limit too.

Panels wired in series add their voltages. Panels wired in parallel add their amps. Your unit’s manual tells you which combos are allowed.

Max solar input by model (watts)

Model	Capacity	Max solar input	Rough “good sun” hours at max input*
Anker SOLIX F3800 Plus	3,840 Wh	3,200 W	~1.7
EcoFlow DELTA Pro 3	4,096 Wh	2,600 W	~2.3
Jackery Explorer 2000 Plus	2,042.8 Wh	1,400 W	~2.1
EcoFlow DELTA 3 Plus	1,024 Wh	1,000 W	~1.5
EcoFlow DELTA 2 Max	2,048 Wh	1,000 W	~2.9
Jackery HomePower 3000	3,072 Wh	1,000 W	~4.4
BLUETTI Elite 100 V2	1,024 Wh	1,000 W	~1.5
BLUETTI Elite 200 V2	2,073.6 Wh	1,000 W	~3.0
Anker SOLIX C2000 Gen 2	2,048 Wh	800 W	~3.7
Anker SOLIX C1000	1,056 Wh	600 W	~2.5
EcoFlow DELTA 3	1,024 Wh	500 W	~2.9
BLUETTI AC180	1,152 Wh	500 W	~3.3
Jackery Explorer 1000 v2	1,070 Wh	400 W	~3.8
Jackery Explorer 2000 v2	2,042 Wh	400 W	~7.3
EcoFlow RIVER 3 Plus	286 Wh	220 W	~1.9

*Very rough: capacity ÷ (max input × 0.7), assuming you own enough panels to hit the max and the sun cooperates. Panels rarely deliver their full rated watts; heat, angle, clouds and shade all cut output. Our 0.7 factor is a planning assumption, not a measurement. DJI models are left out because their solar figures in our database aren’t confirmed.

How many panel watts should you buy?

• Weekend camper: 100 to 200 W of portable panels keeps phones, lights and a fan going on a small or ~1 kWh unit.
• Outage backup: aim for 400 W or more on a ~1 to 2 kWh unit so a sunny day can make a real dent in your fridge’s daily use. See how long a power station runs a fridge.
• Off-grid-ish: max out your unit’s input. That’s where the 1,000 W+ models shine.

Same-brand or third-party panels?

Same-brand panels are the “it just works” option: matching connectors, known voltages. Third-party panels can save money, but you must check open-circuit voltage (Voc), connector type and whether you need an adapter. When in doubt, follow the power station manual’s solar section to the letter.

Common oopsies

1. Too many panels in series → voltage over the limit. Check Voc, and remember Voc rises in cold weather.
2. Shading one panel → in series, it can drag down the whole string.
3. Laying panels flat → tilting toward the sun usually helps a lot.
4. Panels behind a window → glass cuts output. Put them outside.

Bottom line

Match the watts, respect the volts, don’t forget the amps. Then let the sun do the work. Compare every unit’s solar input in the spec database and size your daily needs with the runtime calculator.
