Renogy vs Jackery vs EcoFlow vs BLUETTI solar panels: price per watt, and the plug catch

Price per watt: how the nine compare

Price per watt is the fairest single number for a solar panel, because a 200W panel in the same light makes roughly twice what a 100W one does, whatever the badge. It is the price divided by the maker’s rated output at standard test conditions (STC, the lab figure every maker prints), and the cards below carry the live prices to divide. At each maker’s own UK store on 21 October 2026, the order ran, cheapest per watt first: Renogy’s E.FLEX 200W; Renogy’s 220W Lightweight Portable Solar Suitcase; Renogy’s 100W suitcase; Jackery’s SolarSaga 100; Jackery’s SolarSaga 200; then BLUETTI’s 100W PV100D and 200W PV200D, all but level. On those prices the Renogy 220W suitcase cost about half as much per watt as the PV200D, the E.FLEX about 15 per cent less again, and the SolarSaga 200 about three-quarters more per watt than the Renogy suitcase. Two panels on our cards, EcoFlow’s earlier 110W and BLUETTI’s PV120, are sold here only through Amazon listings, so we leave them out of the order; their prices are on their cards.

Two honest notes on that list. The EcoFlow panel on our card is the earlier 110W model, with a separate kickstand case, a separate XT60 cable and, by EcoFlow’s own comparison table, a year’s warranty. EcoFlow’s own UK store now sells a 110W Lightweight panel with a built-in cable and a 220W Lightweight, both with five-year warranties; at EcoFlow UK’s prices that day, both sat between Renogy’s 100W suitcase and Jackery’s SolarSaga 200 per watt. Neither is in our catalogue yet, so neither has a card below; if you own an EcoFlow station, look at EcoFlow’s store before buying the Amazon listing. Second, the bifacial ‘up to’ figures some makers quote (Jackery’s 225W, EcoFlow’s 243W and 122W) are their own test numbers, so we rank on the STC rating all four makers publish.

A ranking by price per watt is where to start, not where to stop. The cheapest panel is only the best buy if it plugs into your power station without a chain of adapters, survives being left out in a shower and comes with a warranty you can use. The sections below take those in turn, then say who should buy what. Our portable solar panels page tracks these prices daily.

What a watt is worth in Britain: the winter arithmetic

Rated watts are measured under 1,000 watts of light per square metre at 25°C, which Britain rarely supplies. Rather than guess, we ran the European Commission’s PVGIS calculator, which uses satellite-measured sunlight from 2005 to 2023, for a fixed, unshaded, free-standing array tilted at its best angle with 14 per cent system losses, PVGIS’s defaults. Per kilowatt of panel it gives an average December day of 1.24kWh in London, 0.96kWh in Manchester and 0.66kWh in Glasgow, against 4.00, 3.62 and 3.60kWh in June. December yields about a third of June’s energy in London, a quarter in Manchester and a fifth in Glasgow.

Scaled to these panels, an average December day gives the Renogy 220W suitcase about 270Wh in London, 210Wh in Manchester and 145Wh in Glasgow; a 200W panel about 250, 190 and 130Wh; a 100W panel about 125, 95 and 65Wh. In June the same 220W panel averages about 880Wh in London. Set against a 1kWh power station such as the EcoFlow DELTA 3 Plus or BLUETTI Elite 100 V2, a December day from the biggest panel here refills about a quarter of it in London and a seventh in Glasgow. A fridge-freezer averaging about 21W, the EU’s 2020 average, needs about 500Wh a day before the station’s own draw: the 220W panel covers around half of that on an average London December day, two-fifths in Manchester and under a third in Glasgow, and far less on a dull one.

Those are averages across every kind of December day, and PVGIS models a panel fixed at the ideal angle with nothing shading it. A folding panel you angle towards the sun and move once or twice can do a little better; one propped in a shaded garden, wet, or lying flat does worse, and a run of grey days gives a fraction of the average. The Met Office’s UK series says the same in hours: averaging its monthly figures for 1991–2020, December had 42.7 hours of bright sunshine across the UK against 171.5 in June, about a quarter. Over the last ten Decembers the UK figure ranged from 24.1 hours in 2024, the dullest since 1934, to 48.3 in 2022; December 2025 had 46.5. Plan a panel as a summer and shoulder-season top-up and a slow trickle in winter, not a winter power supply. See will solar panels keep the lights on in a power cut?

The plug: which panel goes straight into which power station

EcoFlow’s stations take solar through an XT60i socket: the DELTA 3 Plus has two, rated 11–60V and 15A each, and the RIVER 3 Plus’s solar input is 11–55V, 13A and 220W at most. EcoFlow’s own panels end in a matching plug and go straight in: the 220W Lightweight lists its connector as XT60, the 110W Lightweight as XT60i-F on a built-in cable, and the earlier 110W on our card came with a separate XT60 cable, by EcoFlow’s own comparison table. A panel with MC4 connectors needs EcoFlow’s Solar to XT60i Charging Cable, which the DELTA 3 Plus manual says is sold separately.

BLUETTI’s current stations use an XT60 solar input: 12–60V and 20A on the Elite 100 V2, 12–60V on the Elite 300, Elite 400 and Apex 300, and 12–28V, 8.2A and 100W at most on the small Elite 10. BLUETTI’s panels end in MC4 connectors, and the difference between its two is what is in the box: the 200W PV200D includes a 1.5-metre MC4-to-XT60 cable, so it is plug-and-go; the 100W PV100D comes with a 3-metre MC4 lead and no adapter, and the Elite 100 V2’s manual lists the MC4-to-XT60 cable as an optional extra. BLUETTI says the panels suit most solar generators with MC4 connectors, and not to mix different panel models. The PV120’s Amazon listing says ‘solar connectors’ and names the BLUETTI stations it suits, without saying whether an XT60 adapter is included.

Jackery’s panels end in Jackery’s own plugs, and which one depends on the version. Its connection guide says the current SolarSaga 200 (model JS-200D) has a DC8020 output that goes straight into the Explorer 1000 v2, 1000 Plus, 2000 v2 and 2000 Plus, among others, while the earlier JS-200A and JS-200C end in DC7909 and need a DC7909-to-DC8020 adapter for those stations. The SolarSaga 100 has come with DC7909 (JS-100A and JS-100C), DC8020 (JS-100F) and, on the 100 Prime, Anderson outputs, and Jackery UK’s SolarSaga 100 page describes an Anderson output with an Anderson-to-8mm cable in one place and a different specification table in another, so check the model number on the panel’s label, and with the seller, before you buy. From a DC8020 panel, the Explorer 240 v2 and 300 Plus need a DC8020-to-USB-C adapter cable that Jackery sells separately, and the older Explorer 240, 500 and 1000 a DC8020-to-DC7909 adapter. Jackery UK’s 100W page lists the Explorer 240 v2, 500 v2, 1000 v2, 2000 v2, 1000 Plus and 2000 Plus as compatible. What Jackery UK does not sell is any adapter between its plugs and MC4 or XT60: a SolarSaga into an EcoFlow or BLUETTI, or a Renogy into a Jackery, means a third-party adapter that no maker here endorses. Treat Jackery panels as Jackery-only, and the reverse.

Renogy is the catch. Its UK pages for the Lightweight Portable Solar Suitcase and the E.FLEX 200W say the panels work with most portable power stations and give full electrical figures, but neither names the plug on the end of the cable. Renogy’s accessory list sells MC4 branch connectors, MC4 extension cables and a ‘solar connector to 5.5 × 2.1mm DC’ adapter, which points to MC4-type connectors, but a hint is not a specification. Before you order, ask Renogy which connector the panel ships with, and budget for your station maker’s MC4 adapter cable: EcoFlow’s Solar to XT60i cable or BLUETTI’s MC4-to-XT60 cable. If you would rather not ask, the same-brand panel is the one that plugs in.

Voltage and current: will the station accept it?

On every station here but one, a single panel of any of these sits inside the input window. The exception is BLUETTI’s small Elite 10, which BLUETTI caps at 28V, 8.2A and 100W of solar, so pair it with a 100W panel such as the PV100D (24.6V, 5.8A) or the Renogy 100W (21.6V, 5.83A). Open-circuit voltages are 23.6V for the Renogy 220W suitcase, 21.6V for the Renogy 100W and the E.FLEX 200W, 23.2V for the SolarSaga 200, 21.6V for the SolarSaga 100, 21.4V for EcoFlow’s 220W Lightweight, 23.5V for its 110W Lightweight and 24.6V for BLUETTI’s PV200D and PV100D, all makers’ STC figures. Short-circuit currents run from 5.8A (BLUETTI’s PV100D) to 12.2A (EcoFlow’s 220W): the Renogy 220W’s 11.5A and the SolarSaga 200’s 11.76A sit under the DELTA 3 Plus’s 15A per port, the Elite 100 V2’s 20A and the RIVER 3 Plus’s 13A, but every 200W-class panel here, from the PV200D’s 10.8A up, is over the Elite 10’s 8.2A.

Two panels in series double the voltage: two Renogy 220W suitcases would be 47.2V open-circuit and two PV200Ds 49.2V, by our arithmetic from the makers’ figures, inside a 60V window but closer to it than a single panel; on the RIVER 3 Plus’s 220W cap a second panel gains nothing. BLUETTI says not to mix panel models, and Jackery’s Solar Panel Series Connector is for two or three of its own panels on v2 and Plus stations, with the same advice to use one model. If you are sizing a station as well as a panel, start with what size power station do I need.

Weight, weather rating and warranty

In the 200W class, EcoFlow’s 220W Lightweight is the lightest at 5.1kg (±0.3kg) on its spec table (the page text says 4.4kg), then Renogy’s E.FLEX 200W at 6.3kg and Renogy’s 220W suitcase at 6.5kg; Jackery’s SolarSaga 200 is 17.5lb (about 7.9kg) and BLUETTI’s PV200D 8.14kg on its leaflet. Folded, the Renogy suitcase is the bulkiest at 588 × 573 × 83mm, because it is a rigid fibreglass case rather than a fabric fold; the others fold to 36–50mm thick. In the 100W class the Renogy 100W suitcase is 4.02kg, Jackery’s SolarSaga 100 4.69kg on its spec table (the same page’s description says 8lb), BLUETTI’s PV100D 4.9kg and the PV120 about 5kg (11.1lb on its listing).

Weather ratings differ more than the prices suggest. IP68 on the SolarSaga 200 (IP67 in other paragraphs of the same Jackery page) and both EcoFlow Lightweight panels, though EcoFlow’s 110W page says the rating covers the panel and not the junction box, and both EcoFlow pages say lightweight panels are not for hanging outdoors for long periods (the 110W page adds vehicles); IP67 on the Renogy suitcases and BLUETTI’s PV200D and PV100D (the PV100D’s page FAQ says IP65, its leaflet IP67); IP65 against splashes on the PV120 listing; and no rating at all on Renogy’s E.FLEX 200W page. Jackery’s SolarSaga 100 is IP68 on paper, but Jackery’s own page says not to leave it in the rain or soak it, which is the sensible rule for all of them: bring a panel in when the weather turns.

Warranties: five years on EcoFlow’s Lightweight panels; three years as standard on the SolarSaga 200, plus a two-year extension that Jackery says applies automatically to a panel bought from its own website, while one bought from a third-party seller, Amazon included, needs a form to claim it, hence ‘(3+2) years’ in its spec table; three years on materials and workmanship for Renogy’s suitcases; 24 months on the SolarSaga 100; two years, prorated, on the E.FLEX; 12 months on BLUETTI’s PV200D and PV100D; one year on the earlier EcoFlow 110W by EcoFlow’s comparison table; and nothing stated on the PV120’s Amazon listing. The SolarSaga 100 has USB-A and USB-C sockets on the panel, and the SolarSaga 200 on its built-in charging cable, for charging a phone directly; the Renogy and BLUETTI panels here do not. Per watt, Renogy’s 220W suitcase paired the second-lowest price with three years’ cover and IP67 when we checked, which is why it leads the picks below despite the unnamed plug.

Who should pick which

Best value, with a condition: the Renogy 220W Lightweight Portable Solar Suitcase. It cost about half as much per watt as BLUETTI’s PV200D when we checked, and it is IP67, 6.5kg with built-in kickstands and three years’ cover; its 23.6V and 11.5A suit every station input here except the Elite 10’s. The condition is the plug: confirm the connector with Renogy before ordering and add your station maker’s MC4 adapter cable. The PV200D’s cover is a year.

Cheapest per watt, for fair weather: Renogy’s E.FLEX 200W, about 15 per cent less per watt than the 220W suitcase when we checked, and 6.3kg, but Renogy UK gives it no weather rating and a two-year prorated warranty, and again does not name the plug. Buy it as a panel you set out on dry days and bring in, not one you leave to the weather.

Plug-and-go for a BLUETTI: the PV200D, because the MC4-to-XT60 cable is in the box and BLUETTI’s input figures match its own panel on every BLUETTI station here except the Elite 10. It was the dearest 200W panel here per watt when we checked, so if price matters more than convenience, the Renogy plus BLUETTI’s cable is the alternative. BLUETTI’s PV100D cost about the same per watt and comes without the adapter cable, so for most BLUETTI stations the 200W is the better buy of the two; for an Elite 10, the PV100D plus BLUETTI’s MC4-to-XT60 cable is the BLUETTI pairing that fits its 100W input. See BLUETTI power stations for the units these feed.

For a Jackery: the SolarSaga 200 if your Explorer is a 1000 v2, 2000 v2, 1000 Plus or 2000 Plus, where Jackery’s guide says the current JS-200D version connects directly (check the model number, especially on the Amazon listing), with three years’ cover as standard and two more through Jackery’s extension; the SolarSaga 100 for the smaller Explorers, with 24 months’ cover and USB sockets on the panel, once you have checked which plug it has, since Jackery UK’s page describes an Anderson output. Jackery’s own plugs keep both in Jackery’s ecosystem, which is the point and the limitation; BLUETTI vs Jackery weighs the stations themselves.

For an EcoFlow: not the Amazon 110W on our card, the earlier model with a year’s cover and a separate cable. EcoFlow’s 220W Lightweight has an XT60 plug, 5.1kg, IP68 and five years’ cover, and its 110W Lightweight a built-in XT60i-F cable and five years too; both are sold by EcoFlow UK, and we have not reviewed either yet. Otherwise, the Renogy 220W plus EcoFlow’s Solar to XT60i cable. See EcoFlow power stations.

In the 100W class, on merit: the Renogy 100W suitcase (the cheapest per watt of the 100W-class panels at the makers’ own stores when we checked, 4.02kg, IP67, three years) for any station that takes MC4 through a cable, the Elite 10 included; the SolarSaga 100 for a Jackery; and the PV120 on Amazon (IP65) only if you specifically want BLUETTI’s 120W, since BLUETTI UK did not list it when we checked and sells the PV100D and PV200D instead. If your real need is phones, a torch and a radio, a power bank charged from the mains beats any panel; the kit builder sizes the rest.

How we priced this, and what changes

The order in the first section uses each maker’s own UK store prices on 21 October 2026: Renogy UK, Jackery UK, BLUETTI UK and, for the Lightweight panels, EcoFlow UK. The EcoFlow 110W and PV120 cards are Amazon listings, so they are not in the order; their prices are on the cards. The cards refresh daily and this text does not, so if the cards below put the panels in a different order, the cards are newer: divide a card’s price by the rated watts for the current price per watt. Amazon’s SolarSaga 200 listing still describes the earlier version (24.3 per cent efficiency, a carry bag) while Jackery UK describes the current bifacial one, so check which version a seller is shipping, because the earlier SolarSaga 200 versions end in a DC7909 plug rather than DC8020. This is a researched comparison from the makers’ specifications and PVGIS; none of these panels has been through our hands, and we say so on every card.
