5V 1W Mini Solar Panel 89.5×89.5mm for Arduino, IoT & DIY Projects

The 5V 1W Mini Solar Panel is a compact photovoltaic panel designed for low-power electronics, Arduino, IoT and DIY renewable energy projects. With a rated output of 5V and up to about 200mA under good sunlight conditions, this small solar panel is suitable for learners, electronics hobbyists, STEM facilitators and project builders who want to experiment with solar energy.

Its small 89.5mm × 89.5mm size makes it easy to mount on mini projects such as solar-powered sensors, small robots, garden lights, school science projects, battery charging circuits and outdoor IoT prototypes. It can be used with Arduino, ESP8266, ESP32 and other low-power microcontroller projects when combined with the right charging, regulation or power management circuit.

This panel is especially useful for teaching basic solar energy conversion, renewable energy systems, photovoltaic output testing, battery charging principles and off-grid electronics. It is not meant to power high-current devices directly, but it is perfect for learning, prototyping and powering small loads under direct sunlight.

For best performance, place the panel under strong sunlight and connect it through the appropriate diode, charge controller, voltage regulator or battery charging module depending on your project.
