Step 9: Interconnections between the PV panel and the Lamp
Insert 15 ohm resistor in the terminals 1 and 2 of the terminal strip as shown in the figures. Connect good quality red/black twin wire from the PV panel to the LED lamp. Red (+) wire should be connected to terminal no 2 and black (-) wire should be connected to terminal 3. The red/black wire should be long enough to run it from the roof to the place where you intend to install this lamp.
