Compact, durable, and efficient — the CL-SM3P solar panel is a perfect power source for your low-power projects. With its 18 V open-circuit voltage and 3 W output, it’s ideal for charging small batteries, powering sensors, IoT nodes, weather stations, or microcontrollers like the Raspberry Pi Pico or ESP32 (with a proper regulator).

Built on monocrystalline cells, it delivers high conversion efficiency even under low-light conditions. The lightweight, epoxy-coated surface provides excellent protection against humidity and scratches, making it suitable for both indoor experiments and outdoor setups.
