Important Information About PV Solar Power

PV solar power is completely different from other types. Of the 2 main types of solar energy, active and passive, PV solar power is active. Let's take a look at it.

Solar Panel

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

You can find two main types of solar panel. From a distance, both look like rectangular boxes. Both transform rays from the sun into energy, but in 2 totally different ways. The terms for the two solar panel kinds are actually solar thermal collector as well as photovoltaic module.

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

2. Photovoltaic module: This next kind of solar panel collects solar energy and converts it to usable electrical power.

Meet the PV

To respond to the question, what's PV solar power, we should know what the PV is. The quick answer is that PV pertains to a photovoltaic module. "P" is actually for photo and "V" for voltaic.

In simple terms, "photo" pertains to sunshine and "voltaic" pertains to electrical energy. PV panels convert rays from the sun into electric energy. Sunshine flows into the solar panel. Electric energy flows out of the solar panel.

A PV solar panel is actually made up of lots of photovoltaic (light to volts) cells. These particular cells are electrically connected, and covered with glass. The glass offers electrical insulation. It is also good safety from weather conditions and other destructive forces.

When minimal power is required, such as that essential to power a smaller appliance, a single PV solar panel is enough. When much more power is required, an "array" of solar panels is built by linking panels to one another. If the power will not be provided to the power grid, the solar panel(s) is linked to a charge controller, and battery. If it is meant for on-grid use, the solar panel array would be connected to an electrical inverter.

What Is PV Solar Energy?

Standard silicon solar panels transform approximately fourteen to seventeen percent of sunshine into usable electricity. That is not much. Late in 2006, though, a new photo voltaic cell was released. Solar panels that make use of the new cell could transform into electricity twenty two percent of the daylight they collect. Theoretically, the most that the cells of a solar panel could convert is alleged to be around 26 to 27 percent of incoming rays from the sun.

How does it really work? Let's look at a really simple explanation.

Every photovoltaic cell in a PV photo voltaic panel is a semiconductor. When sunshine hits these cells, a certain part of the sunshine is absorbed by those silicon cells. The cells absorb that part of the sunlight's power. The cells then transfer the absorbed daylight's energy to the electrons within the silicon. The electrons start to move, and this creates an electric current. Metallic contacts built into the top and bottom of the PV cells draw off that current and it's dispatched to the grid or battery. It is now usable electrical power. The power grid sends it on its way, in case you have used an on-grid connection. If you're using a battery, it is saved within the battery awaiting your need.
