How Solar Power Generation Works

There are two main methods of solar power generation: photovoltaic (PV) panels and concentrated solar power (CSP).

  1. Photovoltaic (PV) panels: Photovoltaic panels, also called solar cells or modules, are made of semiconductor materials that can absorb sunlight and convert it into electricity through a process known as the photovoltaic effect. When sunlight hits the solar cells, the electrons in the semiconductor material are excited and start to move, creating a flow of electric current. This direct current (DC) is then passed through an inverter, which converts it into alternating current (AC) that can be used to power electrical devices or supplied to the power grid.

  2. Concentrated solar power (CSP): CSP systems use mirrors or lenses to concentrate a large area of sunlight onto a smaller area, usually a pipe filled with a heat transfer fluid (HTF), such as molten salt or synthetic oil. The HTF is then heated to high temperatures, which is used to generate steam and drive a turbine, producing electricity. CSP systems can store the thermal energy for later use, making it a more reliable and stable power source compared to PV systems, which are dependent on sunlight availability.

Types of Solar Panels

There are three main types of solar panels, which are differentiated by the type of material used to create the solar cells:
