Specification: Type: Semi-Finished DIY Solar Panel Material:Monocrystalline Silicon Cell Grade: Grade A Efficiency: 21% Pmax: 5W Vpmax: 1V Ipmax: 5A Lamination (top to bottom): ETFE+PTFE+2xEVA+Cell+2xEVA+PET Flexible: No Foldable: No Panel Size: 170x170x3mm Package Material: EPE Foam Bag Package Size: 200x250mm Gross Weight: 130G Color: Dark Blue Instruction: 1.This DIY panel is designed as 1V, 1.5V and 2V. 2.On the back the positive and negative anodes is mark as "+" & "-". 3.Connect them in series to get the voltage added. 4.Connect them in parallel to get the current added. 5.Example: If you buy some 2V panel and wanna DIY a 18V panel, just connect 9pcs 2V panel in series. Tools Required: 1.Welding Wire: To connect the pole 2.Welding Wire: To melt the wire 3.Waterproof Glue: To fill the gap to prevent water penetration 4.5V Regulator: Necessary for 5V devices charging 5.Diode: Necessary for storage battery charging to prevent reverse charging. Note: 1.Please find out the positive and negative pole before use. 2.This is a DIY panel, if you know nothing about solar panel and electricity, please don`t buy it. Tips on If the "+" & "-" mark is lost: Use a multimeter to find them out: 1.Adjust it to the DC Voltage mode 2.Connected the red and black stylus to the anodes 3.If the multimeter show a positive reading, then the red stylus side is the positive pole and the other is the negative pole.
