You’ve probably heard of the abbreviation PV recently and wondered what it means. Well, PV stands for “Photovoltaic” (photo stands for light, whereas voltaic is the unit of electrical force), which is electricity from the sun’s energy.
But how does it work, and where is it applied? This article will briefly explain all that!
How Does PV Work?
PV cells are used in solar systems to collect solar energy. These cells use an inverter to transform solar energy from Direct Current (DC) into Alternating Current (AC). The AC is then used for your household power needs.
The photovoltaic process, usually done to create a voltage, occurs when a substance like silicon transforms sunlight into electricity. A thin glass sheet should be available to laminate the PV cells. Photons from the sun’s rays typically hit the silicon of the PV cells, igniting their electrons which extend across the layers. Then electric current forms when the electrons gather through the wiring built into the PV cells.
The amount of electricity produced primarily depends on the sun’s strength. The more the sun’s rays, the more electricity.
Different Types of Solar Panels
Solar rays striking the earth’s surface directly usually produce direct solar power. There are two ways to gather these rays:
- Solar thermal systems
- Solar PV panels (commonly seen on rooftops and solar farms)
Solar PV and solar thermal panels are the two forms of solar energy systems. Despite having a similar appearance, they serve different purposes. Simply put, solar PV technology generates electricity, while solar thermal technology provides heat.
Solar thermal and solar photovoltaic systems can operate independently or together.
A solar panel has various PV cells, depending on the output voltage and current which the solar panel provides. They are available in multiple sizes from approximately 5 to 400 watts maximum output when producing direct current. (1)
What Is a Solar Array?
You can create a solar array by stringing several solar panels. The solar array’s size will depend on the energy you desire for it to produce for you. A typical house installation consumes up to around 10kWp, although this will vary with your usage.
Now that you understand PV and how it works, you can help the planet by reducing your reliance on fossil fuels and switching to solar power! It’s a great way to save money while also being eco-friendly.
