Which Brands Make Bifacial Portable Solar Panels?
If you search for bifacial portable solar panels, several brands are likely to appear, including Anker, Jackery, EcoFlow, ZOUPW, and GTPOW.
But a brand name alone does not tell you which panel is right for your needs. Two 100W bifacial panels can differ in cell technology, weight, folded size, weather protection, and warranty coverage.
This guide introduces several brands with bifacial folding solar panels and explains what to compare before buying. It is not a ranking or a complete list of every product on the market. Product specifications and availability can change, so always check the manufacturer's current information for the exact model.
Brands That Offer Bifacial Portable Solar Panels
The following brands offer examples of bifacial folding solar panels. Some focus on the 100W class, while others offer higher-output models. Compare products within similar wattage classes whenever possible.
100W-Class Options
Anker SOLIX — PS100
The Anker SOLIX PS100 is a 100W bifacial folding panel featuring N-type solar cells and a stated conversion efficiency of 25%+. It has an IP68 rating and a listed 5-year warranty in the U.S. market. Anker lists the panel at approximately 2.8 kg, or about 3.2 kg including the stand.
Jackery — SolarSaga 100 Air
The SolarSaga 100 Air is a 100W bifacial folding panel using PERC cells, with a stated conversion efficiency of 23%. It weighs approximately 3.2 kg and has an IP68 rating. Jackery lists a 3-year warranty on its U.S. product page; check the terms for your purchase location.
GTPOW — 100W Bifacial Portable Solar Panel
GTPOW offers a 100W bifacial folding panel with monocrystalline cells and a listed conversion efficiency of 25%. Its current product specifications list a weight of approximately 2.2 kg and an IP67 protection rating. It is an option to consider if you want a portable 100W panel with a relatively light carrying weight.
Higher-Output Options
EcoFlow — NextGen 220W Bifacial
The EcoFlow NextGen 220W is a higher-output option, with 220W of front-side rated power and up to 175W from the rear side under suitable conditions. It uses N-type TOPCon cells, has a stated conversion efficiency of 25%, and carries an IP68 rating. Its weight is approximately 7 kg, making it a different category from the 100W panels above. EcoFlow lists a 12-month warranty for the U.S. market.
ZOUPW — Bifacial Folding Panels
ZOUPW offers higher-wattage bifacial folding models, including 180W and 230W options. Its product listings describe N-type 16BB cells, up to 25% conversion efficiency, and IP68 protection. Specifications, weight, and warranty terms vary by model and seller, so check the exact listing before comparing products.
These are examples of brands with bifacial portable panels, not a complete market list. Other manufacturers may offer similar products, and new models may become available over time. Read also: Bifacial vs. Monofacial for Portable Use
What Should You Compare Between Brands?
Once you have a shortlist, look beyond the brand name. These four factors will help you make a more useful comparison.
1. Front-Side Rated Power vs. Rear-Side Gain
Start with the front-side rated power. This is the panel's main output rating under standard test conditions.
The rear side can capture reflected sunlight, but the additional energy depends on the surroundings, ground surface, panel height, and whether the back is shaded.
When a manufacturer advertises an additional 20% or 28% from the rear side, treat it as a potential gain under favorable conditions—not a guaranteed increase in everyday use.
For a fair comparison, look at front-side rated power first. Then consider rear-side performance as an additional benefit. Read also: Do Bifacial Solar Panels Work on the Ground?
2. Cell Technology and Conversion Efficiency
Check whether the manufacturer identifies the cell technology, such as N-type, PERC, or TOPCon, and whether it provides a conversion efficiency figure.
For example, the models listed above use different cell technologies and publish different efficiency figures. However, those numbers are not always directly comparable.
Some manufacturers report cell efficiency, while others may report module efficiency. Cell efficiency describes the performance of the solar cells themselves; module efficiency accounts for the complete panel.
If the manufacturer does not clearly explain what its efficiency figure represents, avoid assuming it is directly comparable with another brand's number.
3. Weight and Folded Dimensions
Weight matters if you plan to carry your panel frequently. A lighter 100W panel may be easier to move between campsites, while a heavier, higher-output model may make more sense for car camping or RV use.
Check whether the listed weight includes the stand, carry bag, and cables. For example, Anker provides separate weight figures for the panel and the panel with its stand.
Folded dimensions are equally important. A long, narrow panel may be harder to pack than a more compact design, even if the two weigh about the same.
Before buying, compare the packed dimensions with the storage space in your backpack, vehicle, or RV.
4. Weather Protection and Warranty
An IP rating gives you an indication of a product's resistance to dust and water, but it does not mean the panel can withstand every outdoor condition.
For example, IP68 does not mean unlimited underwater use. Check the manufacturer's stated testing conditions and whether the rating applies to the complete panel, junction box, and connectors.
Warranty coverage also varies by model and region. Anker, Jackery, EcoFlow, and GTPOW list different warranty periods and coverage structures. Do not compare warranty length alone. Check what is covered, including workmanship, power output, and other components, as well as any exclusions.
How to Choose the Right Bifacial Portable Solar Panel
The best panel depends on how you plan to use it.
For hiking and frequent carrying: Prioritize weight and folded dimensions. A compact 100W-class panel may be more practical than a larger, heavier model.
For car camping and RV use: You may have more room for a higher-wattage panel. Consider your daily energy needs and whether your power station can accept the panel's output.
For reflective environments: If you often camp on snow, sand, or other light-colored surfaces, a bifacial panel may have more opportunity to capture reflected light. On dark soil or grass, the rear-side contribution may be smaller.
For long-term value: Compare the total price, warranty coverage, weather protection, and ease of carrying. A lower purchase price does not automatically mean better value if the product has limitations that matter to your use.
Conclusion
Several brands now offer bifacial portable solar panels, from compact 100W models to higher-output folding designs. But choosing one is about more than brand recognition. Compare front-side power, cell technology, weight, folded size, weather protection, and warranty within the same wattage class. Then check the current specifications for the exact model before making your decision.
