Looking for the best portable solar panels? XTAR SP100, the 100W folding solar panel is perfect, no matter for upgrading your existing solar power system or stepping into solar power in your off-grid adventure.
Portable and Durable
It weighs only 9.7 pounds, lightweight for girl RVers. A size of 24.4x21.1x1.2 inches in fold up, very convenient for small RVs like Class Bs and camper vans.
The large blue handle has built-in magnets that hold it tight, easy to carry around and set up. The two foldable kickstands on the portable panel have three adjustable positions. That keeps the panel working best even in the winter, spring, or fall when the sun is low. A piece of velcro holds them down tight to avoid flapping around when you're not using them. The metal grommet on each corner of the portable panel allows you to hang it to your vehicle or ground to avoid being blown away.
High-Efficient and Versatile
It has a max of 23.7% high efficiency, with an ETFE coating that is almost 100 permeable to UV rays. It is also stain-resistant, scratch-resistant, and non-stick surface. Some tests in the US found that this 100W folding solar panel generated 20% more power than other 120W solar panels.
Compatible with different portable power stations and batteries. With a DC7909 (8mm) connector or MC4 Y-cable, it can charge generators from Jackery, Goal Zero, Bluetti, etc. When connecting the XTAR EU4S charger, it can charge your laptops, phones, and other USB devices directly. To double efficiency, it’s great to use two 100W solar panels in parallel via a Y-cable. Anderson and 8mm connector optional.
XTAR EU4S is a DC to DC USB 45W charger with 4 output ports (sold separately). It has a built-in MPPT controller to provide protection against over-current, over-voltage, over-temperature, over-discharge, and short-circuit. In this way, the SP100 solar panel can protect your devices from over-heat damage when direct charging.
