What is PV solar power? You have heard the term, but you are unsure as to its which means. You are vaguely aware that solar power has one thing to do with generating energy from sunlight. But what is PV solar power? Is it different from other kinds of solar power?

PV solar power is different from other types. Of the two main categories of solar power, active and passive, PV solar power is active. Let's appear at it.

Solar Panel

Active solar power relies on solar panels. You could picture them as flat, rectangular boxes on rooftops.

There are two main varieties of solar panel. From a distance, both look like rectangular boxes. Both convert sunlight into energy, but in two diverse methods. The terms for the two solar panel types are solar thermal collector and photovoltaic module.

1. Solar thermal collector: This solar panel takes in solar power from the sun and utilizes it to heat air or water.

2. Photovoltaic module: This second type of solar panel collects solar power and converts it to usable electricity.

Meet the PV

To answer the question, what is PV solar power, we need to know what the PV is. The brief answer is that PV refers to a photovoltaic module. "P" is for photo and "V" for voltaic.

The Merriam-Webster Online Dictionary defines "photovoltaic" this way.

"of, relating to, or utilizing the generation of a voltage when radiant power falls on the boundary more information amongst dissimilar substances."

In easier terms, "photo" refers to sunlight and "voltaic" refers to electrical power. PV panels convert sunlight into electrical energy. Sunlight flows into the solar panel. Electrical power flows out of the solar panel.

A PV solar panel is made up of several photovoltaic (light to volts) cells. These cells are electrically connected, and then covered with glass. The glass gives electrical insulation. It is also very good protection from weather and other damaging forces.

When minimal energy is needed, such as that essential to power a small appliance, a single PV solar panel is adequate. When more power is necessary, an "array" of solar panels is designed by connecting panels to one particular another. If the power will not be supplied to the power grid, the solar panel(s) is connected to a charge controller, and battery. If it is intended for on-grid use, the solar panel array will be connected to an electrical inverter.

What Is PV Solar Power?

PV solar power is solar power in the form of sunlight, which has been collected by a photovoltaic module, and converted into usable electricity.

Conventional silicon solar panels convert about 14 to 17 percent of sunlight into usable electricity. That isn't a lot. Late in 2006, nevertheless, a new solar cell was introduced. Solar panels that utilize the new cell can convert into electricity 22 percent of the sunlight they collect. Theoretically, the maximum that the cells of a solar panel can convert is stated to be about 26 to 27 percent of incoming sunlight.

How does it function? Let's appear at a extremely easy explanation.

Each photovoltaic cell in a PV solar panel is a semiconductor. When sunlight hits those cells, a particular part of the sunlight is absorbed by those silicon cells. The cells take in that component of the sunlight's energy. The cells then transfer the absorbed sunlight's energy to the electrons in the silicon. The electrons start to flow, and this creates an electrical existing. Metal contacts built into the best and bottom of the PV cells draw off that current and it is sent to the grid or battery. It is now usable electricity. The power grid sends it on its way, if you have utilized an on-grid connection. If you are utilizing a battery, it is stored in the battery awaiting your need.

PV solar power is being utilized increasingly with excellent good results, and even though it is true that cloud cover can have an effect on it, the cloudy country of Germany leads the world in successful use of solar panels.
