The science behind photovoltaic
Solar panels, also known as photovoltaic (PV) panels, are made up of individual solar cells that contain a semiconductor material, typically silicon. When sunlight hits the solar cells, it dislodges electrons from the semiconductor material, creating a flow of electricity (DC power). This process is known as the photovoltaic effect.
The efficiency of panels, which refers to the proportion of sunlight they can convert into solar electricity – generating electricity, has improved significantly over the years, thanks to advances in materials science and solar cell technology.
Factors such as temperature, shading, and the angle of the panels can also affect the efficiency of panels, so it’s essential to install them in an optimal location and configuration to maximize their performance.
Converting sunlight into electricity
Solar panels convert sunlight into direct current (DC) electricity, which must be converted into alternating current (AC) electricity to be used by most appliances and to be fed back into the grid.
This conversion is achieved through electricity use from a device called an inverter, which is typically installed near the panels. As the efficiency of the inverter can also impact the overall performance of the solar system, it’s essential to select a high-quality inverter that matches the output of the PV installed.
Additionally, some solar systems include microinverters or power optimizers, which are installed on each solar panel to improve the system’s performance by allowing each panel to function independently of the others, reducing the impact of shading or other performance issues on the entire system.
Solar panel efficiency and performance
