Technologically, EcoFlow relies on N-Type TOPCon monocrystalline silicon for the solar cells. This technology is considered particularly efficient and exhibits high degradation resistance. An efficiency of 25 percent is a remarkable value in the realm of portable solar panels. This means that a quarter of the incident solar energy is converted into electrical energy. The rated power of 160 watts at an output voltage of 21.3 V (Vmp 18.6 V) and a maximum current of 9.1 A (Imp 8.6 A) promises rapid charging of compatible devices.

The N-Type TOPCon monocrystalline silicon cells used in this panel are a premium technology, contributing to its 25% efficiency and better performance in varying temperatures compared to older, more common solar cell types.

Connection is made via standardized photovoltaic connectors, ensuring broad compatibility with most power stations and solar generators on the market. Particularly noteworthy is the IP68 certification. This highest protection class guarantees complete protection against the ingress of dust and even against prolonged submersion in water. This makes the panel extremely resistant to the elements and predestines it for use in harsh conditions – whether in the desert or during heavy rain.

Context Note: The IP68 rating is the same level of protection found on flagship smartphones, meaning this panel can technically survive being submerged in 1.5 meters of water for 30 minutes, though we don't recommend charging while wet.

N-Type TOPCon technology for solar cells is one of the most advanced on the market. It is characterized by higher efficiencies and better performance at high temperatures compared to conventional P-Type cells.

Performance in Specs in Practiceing

In our tests, we put the EcoFlow EcoFlow NextGen 160W Portable Solar Panel through its paces under various conditions. Handling is incredibly simple thanks to the foldable design and integrated kickstands. The panel can be set up and optimally aligned with the sun within seconds. The kickstands are sturdily constructed and hold the panel in position even with light wind.

Pitfall: Partial shading is a major efficiency killer. Even if a small corner of one cell is covered by a leaf or shadow, the entire panel's output can drop by more than 50% due to the way solar cells are wired in series.

Warning: Avoid placing the panel behind glass windows or windshields. Most modern glass has UV coatings that significantly reduce the solar energy reaching the cells, often cutting your charging speed by half or more.

Charging performance, as with all solar panels, varies significantly with external conditions. With ideal summer sunlight, we recorded power outputs close to the 160-watt peak. A test with an EcoFlow Delta 2 power station showed that the panel could charge the power station with an average of 120-140 watts when the sun was direct and unobstructed. This allowed the power station to charge from 0 to 80 percent in about 5-6 hours. In cloudy skies or with angled sunlight, performance predictably dropped, but still provided enough energy to, for example, fully charge a smartphone within two hours or reliably operate a cooler.

For best results, pair the EcoFlow NextGen 160W with a compatible EcoFlow power station, such as the Delta 2, which allows you to monitor charging performance and optimize energy storage.

Buyer Advice: If you plan to use this panel in windy locations, bring small stakes or sandbags. While the kickstands are sturdy, the large surface area of the 63-inch unfolded panel can act like a sail in strong gusts.

The panel's robustness was also evident. A few raindrops or light dust, as found at a campsite, posed no problem whatsoever for the IP68-certified panel. Even a brief stay in a puddle left no traces or impairment of performance. The compact folded size of 23.6 × 22.5 × 1.3 inches and the weight of 12.3 pounds make it an ideal companion for van life, tent camps, or backyard use. It fits in the trunk of a small car or can be easily stowed in an RV.

A minor criticism in Specs in Practiceing is the panel's tendency to lose efficiency during periods of intense heat. While this is a known physical phenomenon for solar cells, it becomes noticeable with direct sunlight over extended periods on hot summer days. Performance then stabilized slightly below the optimal value, but was still good.

For maximum charging performance, you should re-align the solar panel with the sun throughout the day. Even small changes in angle can noticeably improve efficiency. Use the integrated kickstands for this purpose.

Pro Tip: Use the protective carrying case as a secondary kickstand. It is designed to help you prop the panel at a 40–50° angle, which is often more stable than the built-in legs on uneven terrain.
