Crystalline 12 V 2.5 W panel

This monocrystalline solar module delivers 2.5 W at a nominal 12 V and 0.208 A. Its 136 mm by 110 mm footprint and 3 mm profile suit compact off-grid builds. Conversion efficiency is rated at 17 %. The panel weighs 0.065 kg and ships as a single unit.

Makers needing a tiny 12 V source

Hobbyists charging 12 V batteries, powering low-draw sensors or topping up portable packs will find the voltage and current a direct match. Installations that require more than 2.5 W, a different nominal voltage or a ruggedised frame for permanent outdoor mounting should look elsewhere.

12 V working voltage decides fit

The 12 V working voltage is the single figure that determines whether this panel integrates without extra conversion. If the load expects 12 V nominal the panel connects directly; otherwise a regulator or converter becomes mandatory.

Questions about this item

What does the 2.5 W rating mean once the panel is connected to a real load?

Under standard test conditions the panel can deliver up to 2.5 W at its working point of 12 V and 0.208 A; actual output will vary with sunlight intensity, angle and temperature.

How does the 17 % conversion rate affect what the panel can supply in practice?

The 17 % figure means roughly one-sixth of the solar energy hitting the 136 mm by 110 mm active area becomes usable electricity, so output scales directly with available irradiance.

What mounting space and weight should I allow for the 136 mm by 110 mm by 3 mm panel?

The panel measures 136 mm long, 110 mm wide and 3 mm thick, weighing 0.065 kg, so it fits in tight enclosures and adds minimal mass.
