To use a light bulb to find the positive and negative terminals of a solar panel, follow these steps: 1. Connect one wire from the light bulb to one of the wires coming from the solar panel. 2. Connect the other wire from the light bulb to the other wire coming from the solar panel. 3. Observe which wire causes the light bulb to light up.
The positive and negative terminals of the panel are located at either end of this series. One of the easiest ways to identify the positive and negative terminals of a solar panel is to look for the markings on the back of the panel itself. Most panels will have a label or sticker that indicates which end is positive and which end is negative.
Let's look at what the word polarity means. Polarity essentially means that the generator has positive charges on one side and negative charges on the other. The voltage difference allows electric currents to flow from one end of the wire to the other. You need a voltmeter or multimeter if you want to check the polarity of your solar panel.
Typically a solar or photovoltaic cell has negative front contact and positive back contact. A semiconductor p-n junction is in the middle of these two contacts. While sunlight falling on the cell the some photons of the light are absorbed by solar cell.
Even when inside a building, a simple voltage reading will reveal the polarity of a solar panel. Put the red positive meter lead on one side and the black negative lead on the other. This measures across the terminals or wires of the solar panel. You must set the volt meter to read DC Volts.
