How Solar Panels Generate Energy
Solar panels generate energy through a series of processes that involve the absorption and conversion of sunlight. Understanding how solar panels work is essential in realizing the full potential of solar power.
Absorption of sunlight
Solar panels are designed to absorb sunlight, which contains photons. When sunlight hits the surface of the solar panels, the photons are absorbed by the photovoltaic cells.
Conversion of sunlight into electricity
Once the photons are absorbed by the photovoltaic cells, they excite the electrons within the cells. This creates a flow of electricity, known as direct current (DC), within the solar panels.
Role of photovoltaic cells
The photovoltaic cells are responsible for converting sunlight into electricity through the photovoltaic effect. This effect causes the excited electrons to move through the cell and generate an electric current.
Role of Inverters in Solar Panels
Inverters play a crucial role in the functioning of solar panels. They are responsible for converting the direct current (DC) electricity generated by the solar panels into alternating current (AC) electricity that can be used to power household appliances.
Conversion from DC to AC power
Inverters convert the DC electricity generated by the solar panels into AC electricity that is compatible with the household power system. This allows the electricity to be used to power appliances and devices in the home.
Types of inverters: centralized, string, and microinverters
There are several types of inverters used in solar panel systems. Centralized inverters are commonly used in large-scale solar installations and convert the electricity generated by multiple solar panels. String inverters are used in medium-sized installations and convert the electricity generated by a string of solar panels. Microinverters are used in small-scale installations and are installed on each individual solar panel.
How Solar Panels Supply Power to Your Home
Solar panels supply power to your home by connecting to the household power system and providing electricity for appliances and devices.
Connection to household power system
The electricity generated by the solar panels is fed into the household power system through the wiring and fuse box connection. This allows the solar-generated electricity to be used to power appliances and devices in the home.
