This Solar Cell/Panel 12V 250mA (3W) provides you high efficient polycrystalline cells mounted onto a fiberglass PCB and covered with epoxy resin which protects the cells without reducing efficiency. The panel is fairly strong and lightweight and is incredibly durable and reliable. You can use this solar panel to power a convenient appliance with free green energy from the sun. How awesome is that, powering your electronics project using renewable energy, reducing carbon emission and save the Earth!

To simplifying your digital making, this solar panel also comes with wire/lead pre-soldered, saving your time to connect/solder wires to it. With a good buck converter, you can use the solar panel to charge your phone or power bank. Of course, it can also power Arduino UNO and Maker UNO (with proper regulator)

Check out this video by LahisTech, it uses 6V panel, but this 12V panel is compatible with the buck converter :)
