Wiring panels in series for a 24V system

Since solar panels produce 12 volts, if you have a 24 volt system, you will need to wire two panels in series in order to generate this voltage. To wire panels in series, simply connect the positive terminal of one to the negative terminal of the other. Next, connect the remaining positive and negative terminals to their corresponding terminals in the input of the regulator and away you go!

You do of course have to make sure that your regulator is rated for 24 volts. Smaller regulators such as the Sunguard are generally only available in 12 volt versions. We do however sell a 24 volt version of the Sunsaver regulator, and larger regulators such as the Prostar and Tristar ranges can be configured to run on either 12 or 24 volt systems.
