TWELSEAVAN vs SOLUPUP Solar Panels Compared
wattage output
The TWELSEAVAN 120W Foldable Solar Panel delivers significantly more power than the SOLUPUP 30W Foldable Solar Charger. With a rated power of 120W, the TWELSEAVAN is designed to charge larger power stations or run higher-draw devices quickly. The SOLUPUP offers 30W, which is suitable for small electronics like phones and tablets but insufficient for bulkier gear. If you need to replenish a portable power station battery or charge multiple high-capacity devices, the TWELSEAVAN provides four times the energy generation. The SOLUPUP is better suited for minimal power needs.
weight and portability
The SOLUPUP is much lighter and more compact, weighing only 2.4 lb compared to the TWELSEAVAN's 7.05 lbs. This makes the SOLUPUP ideal for backpacking or hiking where every ounce matters. The TWELSEAVAN is heavier and folds to 16.6 × 15.7 inches, resembling a standard briefcase. While the TWELSEAVAN includes a magnetic handle and angle guide for easier setup, its bulk limits its use for ultralight travel. The SOLUPUP includes carabiners to clip directly to a pack, enhancing its mobility. For strict portability, the SOLUPUP is the clear choice.
conversion efficiency
The TWELSEAVAN boasts a higher conversion efficiency of up to 25.8% using upgraded HPBC cells. The SOLUPUP uses monocrystalline silicon technology with an efficiency of 23%+. This means the TWELSEAVAN can convert more sunlight into electricity, potentially charging faster under identical conditions. The TWELSEAVAN also features an ETFE layer with 95% light transmittance, which helps maximize energy capture. While both panels are efficient, the TWELSEAVAN's superior efficiency rating suggests better performance in low-light or variable weather conditions.
water resistance
The TWELSEAVAN carries an IP65 waterproof rating, while the SOLUPUP has an IPX5 rating. IP65 offers complete protection against dust and protection against low-pressure water jets from any direction. IPX5 protects against water jets but does not guarantee complete dust tightness. Both panels can withstand rain and splashes during outdoor use. The TWELSEAVAN's higher rating provides slightly better durability against harsh weather and dusty environments. For most camping and RV trips, both are sufficient, but the TWELSEAVAN offers superior protection specs.
charging ports
The TWELSEAVAN offers more versatile charging options with a 60W USB-C port, an 18W QC3.0 USB port, and an MC4 connector for power stations. The SOLUPUP provides only a 5V/3A USB-A port and a 15W max USB-C port. The TWELSEAVAN's MC4 cable allows direct connection to most power stations via various adapters. The SOLUPUP lacks MC4 output, limiting it to direct device charging. If you need to charge a power bank or power station, the TWELSEAVAN is the only viable option.
