Solar Simplified: Easy-to-Understand Guide to Voltage, Amperage & Wattage
Solar panels generate electricity when sunlight hits the photovoltaic cells, causing electrons to move and create a current. The amperage produced by a solar panel depends on the amount of sunlight it receives and the efficiency of the cells. For instance, on a sunny day, a solar panel might produce a higher current compared to a cloudy day.
