How solar energy works
Solar energy is generated through the conversion of sunlight into electricity, a process known as the photovoltaic (PV) effect. At the heart of this process are solar cells, which are typically made of semiconductor materials, such as silicon, that are capable of absorbing sunlight and generating an electric current.
When sunlight strikes the solar cells, the photons in the light excite the electrons within the semiconductor material, causing them to break free from their atoms. These free electrons are then captured and directed through an external circuit, generating an electric current that can be used to power homes, businesses, or the electrical grid.
Solar panels, which are the building blocks of a solar energy system, are composed of numerous interconnected solar cells. These panels are strategically placed on rooftops, in open fields, or on tracking systems that follow the sun's movement to maximize the amount of sunlight they receive and the resulting energy production.
The electricity generated by the solar panels is then converted from direct current (DC) to alternating current (AC) through an inverter, which is a critical component of a solar energy system. The AC electricity can then be used to power homes and businesses or fed back into the electrical grid, allowing solar energy producers to offset their energy costs or even generate additional income through net metering programs.
Types of solar energy systems
Solar energy systems can be broadly categorized into two main types: grid-tied (or grid-connected) systems and off-grid systems. Each type of system has its own unique characteristics and applications, catering to the diverse energy needs of individuals, communities, and businesses.
