What is it?
A solar PV (photovoltaic) installation refers to the setup of solar panels or modules to harness sunlight and convert it into electricity using photovoltaic technology.
Photovoltaic cells are semiconductor devices that generate direct current (DC) electricity when exposed to sunlight.
When multiple cells are connected in a structured manner within a solar panel, and several panels are installed together, it forms a solar PV system.
How does it work?
In simple terms, a solar PV (photovoltaic) installation works by converting sunlight into electricity through the use of solar panels. Here’s a step-by-step explanation:
Sunlight Exposure: Solar panels are installed in a location where they can receive sunlight. This is typically on rooftops, open fields, or other surfaces with good exposure to the sun.
Photovoltaic Cells: Each solar panel is made up of photovoltaic cells, which are semiconductor devices. When sunlight hits these cells, it excites electrons within the material, creating an electric current.
Direct Current (DC) Electricity: The electric current generated by the photovoltaic cells is in the form of direct current (DC). However, most of our electrical devices and the power grid operate on alternating current (AC).
Inverter Conversion: The DC electricity is sent to an inverter, a device that converts it from DC to AC. This makes the electricity compatible with the standard electrical systems used in homes, businesses, and the power grid.
Powering Appliances or Grid Connection: The converted AC electricity can then be used to power appliances and devices in the building where the solar panels are installed. If the solar PV system produces more electricity than is immediately needed, the excess can be fed back into the electrical grid, often earning credits or compensation for the system owner.
That’s essentially how a solar PV installation works. It’s a clean and renewable energy source that directly harnesses sunlight to generate electricity, providing a sustainable alternative to traditional fossil fuel-based power generation.
