Hi! There is two models the one has brown backside and only two connections, plus and minus. The model with black backside has ten connections and there has to be soldered a diode to two of the connections To get a wire instruction for the black one, go down to "Questions and Comments" and click on the first link. "Please provide some instruction on proper connections to solder pads!!" There is an important description on how to connect the wires. The Solar Panel works fine and gives plenty of power by low light conditions. There was a plastic cowering that was crumbled and wrinkled badly, I had to remove it, despite that it should be there for protection. But anyway a good deal. Thanks again to Banggood for good service and good prices.

Amazing features, high current and 6 volts which is compatible with arduino.

Solar panel nice working.I connect to water pump Fast delivery.

I am using it to charge a 18650 battery that is powering an ESP8266 to read and post over MQTT the temperature and pressure every 10 minutes. Without the solar panel the system was working 42 days. After that I am recharging the 18650 battery. Now with the solar panel I hope that will few days of full sun per week to last for years. Basically what is consumed during the night will be gained during the day

J'en ai monté 5 en serie sans diode. Résultat : 19.2V x 0.48A P=9.216W Soit une tension de 3.84V en charge Une tension à vide de 37V soit 7,4v par cellule. Il y avait bien entendu le plein soleil. Je suis satisfait, à voir la durée dans le temps sans protection.
