Compact 12 V 3 W solar module

This polysilicon panel delivers 12 V at 3 W in a 145 mm square frame weighing 81 g. The 2.6 mm thin casing makes it easy to mount on curved or flat surfaces for DIY experiments. It is aimed at hobbyists, educators and anyone building a tiny off-grid charger. No controller or battery is included.

Suits low-power portable projects

The module works well for phone top-ups, small water pumps, science kits and home lighting prototypes. Buyers who need more storage or sustained overnight output should look at larger arrays with integrated charge management. It cannot run high-draw appliances or multi-panel installations without extra hardware.

3 W at 12 V output

The single deciding specification is the 3 W rating at 12 V, which sets the current ceiling for every downstream device. Match your load to this figure before purchasing.

Questions about this item

How do I mount the 145 x 145 mm panel and what wiring mistake should I avoid?

Use the compact 2.6 mm thick frame to fix the panel securely, then connect the leads with correct polarity to the 12 V input of your charge controller or device.

What upkeep will the polysilicon cells and casing need over time?

Wipe the black green surface occasionally with a damp cloth to keep the 3 W output steady; the solid casing needs no further servicing.

What limits output first when the 3 W panel runs continuously in sun?

The 3 W rating means current falls once the load exceeds what the 12 V polysilicon module can sustain.
