What is PV solar power? You have heard the term, however you are unclear regarding its definition. You are slightly conscious that solar energy has something to do with making power from sunlight.
However what is PV solar power? Is it different from other types of solar power? PV solar power is different from other kinds. Of the two primary groups of solar power, active and passive, PV solar power is active. Let’s take a look at it.
Active solar power depends on solar panels. You might describe them as flat, rectangle-shaped boxes on roofs. There are 2 primary kinds of solar panel. From a distance, both look like rectangle-shaped boxes. Both transform sunlight into power, but in 2 different methods.
The terms for both solar panel types are solar thermal collector and photovoltaic module.
- Solar thermal collector: This solar panel absorbs solar energy from the sunlight and uses it to heat air or water.
- Photovoltaic module: This 2nd sort of solar panel gathers solar energy and transforms it to usable electrical power.
Meet the PV
To answer the question, what is PV solar power, we should understand what the PV is. The short answer is that PV describes a photovoltaic module. “P” is for photo and “V” for voltaic.
The Merriam-Webster Online Dictionary defines “photovoltaic” in this manner.
“of, relating to, or utilizing the generation of a voltage when radiant energy falls on the boundary between dissimilar substances.”
In less complex terms, “photo” refers to sunlight and “voltaic” refers to electrical power. PV panels transform sunlight into electrical power. Sunlight moves into the photovoltaic panel. Electrical energy flows out of the photovoltaic panel.
A PV solar panel is composed of numerous photovoltaic (light to volts) cells. These cells are electrically attached, and then covered with glass. The glass supplies electrical insulation. It is likewise great protection from weather and other destructive forces.
When minimal power is required, such as that necessary to power a small home appliance, a solitary PV solar panel is enough. When more power is required, an “array” of solar panels is developed by attaching panels to one another. If the power will not be provided to the power grid, the solar panel(s) is attached to a charge controller, and battery. If it is meant for on-grid usage, the solar panel array will be linked to an electrical inverter.
What is PV solar power?
PV solar power is solar energy in the form of sunlight, which has been gathered by a photovoltaic module, and converted into usable electrical power.
Conventional silicon solar panels convert about 14 to 17 percent of sunlight into functional electrical power. That isn’t much. Late in 2006, however, a new solar cell was presented. Solar panels that utilize the new cell can convert into electrical power 22 percent of the sunlight they gather. In theory, the maximum that the cells of a solar panel can convert is claimed to be around 26 to 27 percent of incoming sunlight.
How does it work? Let’s take a look at a very basic description below!
Each photovoltaic cell in a PV solar panel is a semiconductor. When sunlight strikes those cells, a particular part of the sunlight is absorbed by those silicon cells. The cells absorb that part of the sunlight’s energy. The cells then move the absorbed sunlight’s energy to the electrons in the silicon.
The electrons start to move, and this produces an electrical current. Metal contacts developed into the top and bottom of the PV cells drain that current and it is sent out to the grid or battery. It is now functional electricity. The power grid sends it on its way, if you have used an on-grid link. If you are utilizing a battery, it is kept in the battery awaiting your requirement.
PV solar power is being utilized significantly with great success, and while it is true that cloud cover can impact it, the cloudy country of Germany leads the world in effective use of solar panels.
