We don’t review many solar panels at The Verge, but the tech inside Bluetti’s incredibly portable Sora 500 panel makes it worth a deeper look. The new N-Type panels made by Bluetti and others give you more bang for the buck, pound, and square inch. That’s a big deal for vanlifers like me who depend upon these beefy portable solar panels to extend off-grid stays.
In real-world testing, I saw Bluetti’s 500W panel deliver 509W to my van’s power station, allowing me to generate over 800W when combined with the three sad 140W monocrystalline solar panels I have installed on top of my van. That kind of stationary output is fantastic. I typically consume about 1.6kWh a day, so this array lets me add a full day’s worth of charge in only two hours. I just wish that Bluetti had made the Sora 500 bifacial like Jackery and newcomer Zoupw did with their even lighter, high-wattage, portable, N-Type panels designed to maximize output in less than ideal conditions.
The Sora 500 is priced at €849 in Europe — it isn’t being sold in the US yet. Bluetti spokesperson Ellen Lee tells me that the company wants to bring it to the US market but it’s “currently navigating some shifting regional policies and trade dynamics.” Things that Zoupw and Jackery managed to sort out already.
Bluetti’s single-sided Sora 500 panel uses TOPCon (Tunnel Oxide Passivated Contact) cells, an N-Type technology which is replacing older PERC (Passivated Emitter and Rear Cell) tech. Compared to PERC, TOPCon panels do better in low-light, deal with high temperatures better, and degrade more slowly. TOPCon panels can achieve higher efficiencies (often ~23–25 percent) compared to typical PERC panels (~20–23 percent), depending on implementation.
The Sora 500 does well in shading tests, but partially shading the center four panels creates the most chaos, dropping from over 500W of output to just 50W. The output from the Sora 500, plugged into the LV (low voltage) solar input of a EcoFlow Delta Pro 3 solar generator, dropped to just 50W when shading the four center panels. You can see my roof-top panels producing 302W on the HV input. The Sora 500 did much better when I shaded other panel combinations, including the four just right of center. Blocking the four panels right of center dropped output from over 500W to 276W.
All these advantages mean that you’ll get more for your money, as soon as you unfurl all 12 panels of the Sora 500 and over their extended lifetime. The panel also features an IP67 resistance to dust and water and an ETFE coating that makes it easier to wipe away dirt that interferes with solar intake.
Lightweight portables are no match for gusts of wind, this one was about 10 - 12 knots.
In my mid-March testing in the south of France at an altitude of about 600 meters, I was regularly seeing the Sora 500 delivering above its rated output, measuring as much as 509W on a cool and cloudless day. It also does a good job of handling the sun being partially shaded.
