What is Photovoltaic (PV)?

Overview

Photovoltaic (PV) technology is a method of generating electricity by converting sunlight into electrical energy. This process occurs in solar panels, which are made up of many small units called photovoltaic cells. When sunlight hits these cells, it excites electrons, creating an electric current that can be used to power homes, businesses, and even feed electricity back into the grid. The way PV systems work is relatively straightforward. When sunlight strikes the photovoltaic cells, it causes a flow of electricity due to the photovoltaic effect. This electricity can either be used immediately or stored in batteries for later use. Many homes are now equipped with solar panels on their rooftops, allowing them to generate their own power and reduce their reliance on traditional energy sources. The importance of photovoltaic technology lies in its role in promoting renewable energy. As a clean source of power, it helps reduce greenhouse gas emissions and combat climate change. For example, large solar farms can produce enough electricity to power thousands of homes, demonstrating how PV can contribute to a more sustainable energy future.
