Compact 2W 12V Solar Panel
This miniature polysilicon panel delivers 2 watts at 12 volts and 166 milliamps, measuring 136 by 110 by 3 millimetres and weighing 0.052 kilograms. It suits hobbyists, students and makers who need a lightweight source for low-power experiments or portable charging.
Practical limits of 2W output
At 17 percent conversion the cell only produces usable current in direct, unobstructed sunlight; cloud cover or shading drops output sharply. The fixed 12 volt working voltage cannot be adjusted, so a charge controller or regulator is required before connecting batteries or sensitive electronics.
Build and everyday mounting
The rigid 3 millimetre thick casing resists flexing and protects the cells during handling. No mounting holes or cables are included, so users must devise their own brackets, adhesive or solder connections for permanent or temporary installation.

Questions about this item
How do I choose between the 2W and higher-wattage panels in this range?
This panel delivers 2W at 12V with a 17% conversion rate, so select it when space is limited to 136 by 110 mm and the load draws roughly 166 mA.
What does the 12V working voltage mean when the panel is connected to a battery?
Under load the panel holds about 12V and pushes up to 166 mA, which will slowly charge a 12V battery or run a small 12V device directly in full sun.
Does the bare-wire output limit what controllers or batteries I can use?
The two flying leads carry 12V at 166 mA max, so any charge controller or 12V load rated for at least 2W can be connected without an adapter.
