This is a waterproof Mini Solar Panel 1.5W /5.5V suitable for outdoor charging of Li-ion/LiPo batteries. This panel is much more efficient, Quality assured, and Reliable than the commonly available Solar Panels on the market today.

The efficiency of cheap circular solar panels available in the market is in the range of 13-12% whereas my solar panel is assured to give more than 19% as it uses high-efficiency solar Cells (datasheet is attached).

Applications

• You can use this panel for any battery ( single cell Lithium Ion or LiPo ) operated project.
• This solar panel is a perfect fit for the 3D printed enclosure for my DIY Solar Bottle Lamp project.
