Connect the probes to the positive and negative wires from the solar panel and set the multimeter to the direct current voltage setting. If the multimeter shows a reading around 12-20v during peak sunlight times, the solar panel is working and charging the battery. . Solar panels work by converting sunlight into electricity through photovoltaic cells. These cells generate direct current (DC) electricity, which is then converted into alternating current (AC) by an inverter for use in your home. In this. . In order to conduct an effective examination of solar charging systems, several essential factors must be considered: 1. Measure the Voltage of the Solar Panel Itself 2.
