Understanding the Basics of Solar Panels

Solar panels, also known as photovoltaic (PV) panels, are devices composed of several interconnected solar cells. These cells are responsible for converting sunlight into electricity, a process known as the photovoltaic effect. By absorbing photons from sunlight, the semiconductor material within the solar cells generates a flow of electrons, creating an electrical current. This direct current (DC) is then converted into alternating current (AC) using an inverter, making it suitable for use in residential or commercial buildings.

Photovoltaic cells are the building blocks of solar panels, and they are comprised of layers of semiconductor materials such as silicon. These layers have different electrical charges – the top layer is negatively charged, while the bottom layer is positively charged. When sunlight hits the photovoltaic cells, the photons knock loose the electrons from their atoms, creating an electric voltage. This voltage creates a direct current that can be used to power electrical devices.
