1. High-efficiency miniature solar cells can be easily arranged for larger charging applications, including higher voltage and current loads.2. Miniature and compact size, with an eye-catching sturdy housing. These solar panels can provide green energy without the for practical equipment3. In order to achieve certain parameters, the arrangement of solar cell silicon wafers may be slightly different, but the specifications are the same as described4. The solar panel will be covered by PE film, there may be bubbles under the film, this will not affect the performance, you can remove it, just like the film on the phone panel5. As a solar panel, the force of the will affect the performance of the solar cell, please use it in the Maximum : 5 (W)Working current: 019 (A)Working voltage: 18 (V)System voltage: 600 (V)Open circuit voltage: 20 (V)Short circuit current: 02 (A)Number of batteries: 32 (pcs, only)Reference weight: 352gsize:23x17cmMaterial:Polysiliconcolour:blackPackage Contents:1 * Solar PanelOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
