What is PV solar energy? You have heard the term, but you are unsure as to its meaning. You are vaguely aware that solar energy has anything to do with making power from sunlight. But what is PV solar power? Is it various from other types of solar power?

PV solar power is distinct from other kinds. Of the two major categories of solar power, active and passive, PV solar power is active. Let's look at it.

Solar Panel

Active solar power relies on solar panels. You might image them as flat, rectangular boxes on rooftops.

There are two major sorts of solar panel. From a distance, both look like rectangular boxes. Both convert sunlight into energy, but in two various approaches. The terms for the two solar panel types are solar thermal collector and photovoltaic module open in a new browser window .

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

two. Photovoltaic module: This second type of solar panel collects solar power and converts it to usable electrical energy.

Meet the PV

To answer the question, what is PV solar energy, we must know what the PV is. The short 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 energy falls on the boundary among dissimilar substances."

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

A PV solar panel is made up of many 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 solar panel installation .

When minimal power is required, such as that required to energy a small appliance, a single PV solar panel is sufficient. When much more energy is required, an "array" of solar panels is produced by connecting panels to a single yet 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 energy is solar energy in the type of sunlight, which has been collected by a photovoltaic module, and converted into usable electrical energy.

Traditional silicon solar panels convert about 14 to 17 percent of sunlight into usable electrical energy. That isn't a lot save on . Late in 2006, nonetheless, a new solar cell was introduced. Solar panels that make use of the new cell can convert into electricity 22 % of the sunlight they collect. Theoretically, the maximum that the cells of a solar panel can convert is mentioned to be around 26 to 27 % of incoming sunlight.

How does it operate? Let's look at a extremely simple explanation.

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

PV solar energy is being utilised increasingly with fantastic achievement, and even though it is accurate that cloud cover can affect it, the cloudy nation of Germany leads the planet in profitable use of solar panels.
