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

PV solar power is diverse from other varieties. Of the two major 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 may possibly picture them as flat, rectangular boxes on rooftops.

There are two major sorts of solar panel. From a distance, each appear like rectangular boxes. Both convert sunlight into energy, but in two different ways. The terms for the two solar panel sorts are solar thermal collector and photovoltaic module.

1. Solar thermal collector: This solar panel takes in solar energy from the sun and makes use of it to heat air or water.

2. Photovoltaic module: This second kind 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 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 power falls on the boundary between dissimilar substances."

In simpler terms, "photo" refers to sunlight and "voltaic" refers to electrical energy. 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 great protection from climate and other damaging forces.

When minimal energy is needed, such as that necessary to power a tiny appliance, a single PV solar panel is sufficient. When more power is necessary, an "array" of solar panels is designed by connecting panels to 1 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 is not considerably. Late in 2006, nevertheless, a new solar cell was introduced. Solar panels that make use of 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 mentioned to be around 26 to 27 percent of incoming sunlight.

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

Each and every photovoltaic cell in a PV solar panel is a semiconductor. When sunlight hits those cells, a certain element of the sunlight is absorbed by those silicon cells. The cells take in that portion of the sunlight's energy. The cells then transfer the absorbed sunlight's power to the electrons in the silicon. The electrons start to flow, and this creates an electrical present. 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 electricity. The power grid sends it on its way, if you have utilised an on-grid connection. If you are utilizing a battery, it is stored in the battery awaiting your need to have.

PV solar power is becoming used increasingly with great success, and whilst it is accurate that cloud cover can have an effect on it, the cloudy nation of Germany leads the planet in effective use of solar panels. article my solar energy san diego open in a new browser window
