crystalsolar SW01519 1.5W 9V Solar Panel 110mm

Compact 1.5 W solar module

This monocrystalline silicon panel delivers 1.5 W at 9 V with a working current of 0.166 A. Its 110 mm square footprint and 3 mm thickness suit tight spaces in DIY builds. The 19 % conversion rate supports usable output even in weak light. Buyers needing higher wattage for larger systems should look elsewhere.

Integration into low-power projects

The panel connects directly to small loads such as solar toys, lights or phone-charging circuits. Series or parallel wiring is supported for voltage or current scaling. No mounting hardware is included, so builders must provide their own frame or adhesive. Projects requiring regulated output will need an external controller.

Sustained output behaviour

Under continuous illumination the panel maintains its rated voltage and current without active cooling. The thin profile limits thermal mass, so performance follows available light rather than temperature saturation. Output drops proportionally in shaded or overcast conditions. Installations demanding guaranteed minimum power regardless of weather are not a fit.
