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

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

Solar Panel

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

There are two primary types of solar panel. From a distance, both appear like rectangular boxes. Both convert sunlight into power, but in two different techniques. 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 makes use of it to heat air or water.

two. Photovoltaic module: This second sort of solar panel collects solar energy and converts it to usable electricity.

Meet the PV

To answer the query, what is PV solar energy, we have 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 On-line Dictionary defines "photovoltaic" this way.

"of, relating to, or using the generation of a voltage when radiant energy falls on the boundary amongst dissimilar substances."

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

A PV solar panel is made up of a lot of photovoltaic (light to volts) cells. These cells are electrically connected, and then covered with glass. The glass supplies electrical insulation. It is also excellent protection from climate and other damaging forces solar panel installation .

When minimal power is required, such as that needed to energy a tiny appliance, a single PV solar panel is enough. When a lot more energy is required, an "array" of solar panels is designed 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 Energy?

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

Traditional silicon solar panels convert about 14 to 17 % of sunlight into usable electricity. That is not significantly save on . Late in 2006, nevertheless, a new solar cell was introduced. Solar panels that utilize the new cell can convert into electrical energy 22 % 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 work? Let's appear at a really straightforward explanation.

Each photovoltaic cell in a PV solar panel is a semiconductor. When sunlight hits those cells, a particular component of the sunlight is absorbed by those silicon cells. The cells take in that element of the sunlight's energy. The cells then transfer the absorbed sunlight's power to the electrons in the silicon. The electrons commence to flow, and this creates an electrical existing. Metal contacts built into the top and bottom of the PV cells draw off that existing 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 using a battery, it is stored in the battery awaiting your need to have.

PV solar power is being employed increasingly with wonderful success, and whilst it is accurate that cloud cover can influence it, the cloudy nation of Germany leads the planet in successful use of solar panels.
