Mini Polycrystalline Solar Panel for DIY Projects, 2–12V Options
Explore a small solar-powered circuit without starting with a large roof panel. This rigid polycrystalline module comes in three voltage and power options for a matched low-power project. It is for electronics hobbyists choosing a panel around their circuit's actual requirements.
- ✅ Try a small circuit in sunlight — The compact panel provides a solar source for a suitably matched low-power project.
- ✅ Choose around the circuit you are building — Separate voltage options let you select the appropriate module rather than one universal output.
- ✅ Keep the project compact — The rigid epoxy-board format fits smaller DIY layouts.
- ✅ Move the panel when testing exposure — The separate module lets you compare output as sunlight and orientation change.
Match the panel option to the project
Choose 5 W / 12 V, 1.2 W / 5 V or 3 W / 2 V from the available options. These are separate labelled variants, not three selectable outputs on one panel. The 12 V gallery shows a lead with red and black clips; that accessory layout is not established for every voltage option.
Use the module as one part of a compatible solar circuit for low-power lighting or other matched experiments. Output varies with sunlight, orientation, temperature and load, so a headline rating is not a constant supply or a guaranteed charging speed.
One selected panel is supplied. A battery, charge controller, voltage regulator, load and mounting hardware are not confirmed as included. Battery charging needs a controller suited to the panel and battery chemistry; this is not a regulated phone charger and cannot charge a mobile directly.
The 12 V option is illustrated with a clipped lead for a matched circuit.
The pictured clipped-lead panel is not a complete regulated charging system.
Select the voltage option for the circuit rather than expecting one panel to provide every rating.
The lighting scenes show possible project contexts, not included lamps or guaranteed load compatibility.
A charge controller and suitable battery are separate components where the project needs storage.
Match a lamp, fan or pump's requirements to the available panel and circuit output.
The red and black clip layout is illustrated for the 12 V model.
A rigid panel provides a small solar source for a matched project.
Panel orientation and sunlight affect the available output.
The front cell board must be matched to the selected option.
The rear view shows the panel connection area.
The rear junction cover protects the lead connection area; no immersion rating is established.
Check the module and polarity before connecting it to the circuit.
The clips are electrical connection points, not a regulated charging controller.
