A blocking diode, which may also be referred to as an isolationdiode, blocks the flow of electricity into a solar panel. By enablingonly an outward flow, the diode prevents batteries from discharginginto the panel. It also serves to keep out the current from otherpanels in the array. A solar array requires blocking diodes whenit features more than one panel arranged in parallel. Installinga blocking diode requires basic understanding of photovoltaicsystems and electrical wiring.
Choose Blocking DiodesPurchase a blockingdiode that fits the wiring and current of your solarpanel. For large solar panels and arrays that get a greatdeal of sun, select heavy-duty diodes. Ensure the diode is compatiblewith the maximum temperature of your system. Remove any packagingfrom the diode, and identify the positive and negative sides.
Disconnect your solar panel from the array. Flip it over, andlocate the electrical box. On most panels, the box is situatedon the bottom of the panel; it should have two wires extendingfrom one side. Remove the cover from the box, but keep in mindthat doing so may void your warranty. Depending on the design,you may need to cut away the top of the cover or use a heatgun to release the adhesive. Pry off the cover with a screwdriver.
Expose the Positive Solar Panel ConnectorLocate the positive and negative connectors inside the box.If the connectors are not marked with a + or - sign, examine theexternal connection wires. The red wire leads to the positiveconnector, and the black wire leads to the negative connector.Insert a screwdriver into the screw that connects the positivelead to the board. Depending on the design, you may need to removea nutwith an adjustablewrench. Remove off the screw or nut, and set it aside. Liftoff the positive connector.
Connect Electrical Leads to the DiodeIf your diode has wires extending from either side, locatethe positive wire. Bend it in a loop that fits around the positiveconnector. If the diode does not have build-in wires, cut positiveand negative lead wires. Soldereach lead to the ends of the diode. Solder standard ringconnectors to the ends of the leads. Cover the leads withheat shrink tubing or electrical tape. Alternatively, purchasepre-covered positive and negative electrical leads and solderthem to the diode.
Connect the Blocking DiodeSlip the positive lead over the positive connector on the solarpanel. Replace the positive panel lead, and insert the screw ornut back in place. Tighten it to secure the lead.Disconnect all wires from the battery.Slip the negative lead over the positivebattery terminal. This alignment allows the current to flowfrom the panel, into the positive end of the diode, and out thenegative end. The negative end of the diode prevents the currentfrom flowing backward into the panel.
