Compact 2.5W 12V solar panel
The crystalsolar SW2512 is a miniature monocrystalline module that delivers 2.5 watts at 12 volts. Its 136 by 110 millimetre footprint and 65 gram weight suit portable DIY projects, remote sensors or trickle-charging small batteries where grid power is unavailable.
Upgrade from smaller cells
Builders currently using lower-wattage or lower-voltage cells can step up to this panel when a single 12V source simplifies wiring or when 208 milliamps of working current meets the load without series strings. The 17 percent conversion rate makes the jump worthwhile for space-constrained installations that need more energy per square centimetre.
Steady output under sun
Under continuous illumination the panel maintains its rated 12 volt working voltage and 0.208 amp current without the voltage sag seen in short bursts. The solid casing protects the monocrystalline cells during prolonged outdoor exposure, so sustained daily charging cycles remain reliable for low-power autonomous systems.

Questions about this item
What are the exact dimensions and weight of the SW2512 panel for mounting?
The panel measures 136 by 110 by 3 mm and weighs 0.065 kg, making it compact for DIY mounting on small surfaces.
How do I connect the panel to a 12V system without damaging it?
Wire the panel directly to a 12V charge controller or battery, observing polarity; the working current is 0.208 A at 12 V.
Will the monocrystalline cells degrade and need replacement over time?
Monocrystalline silicon cells typically maintain output for decades; no scheduled cell replacement is required for the SW2512.
