How electrical energy is produced – Solar energy is the best example of clean electrical energy

The greatest discovery of man was fire, a helpful form of energy, and then electric power followed next. This energy has been instrumental in developing civilizations. But, how is electricity made? It is produced through the use of fuel sources such as water, nuclear fission, fossil fuels and even the wind.

 

Where does electricity come from?

Different forms of energy can be converted into electricity, but electricity cannot be created out of anywhere. Anywhere we see electricity being produced; we know that it is some different form of energy that is being changed into electric energy – and not electric energy being created. It is about transformation, not about creation. In hydro-electric power plants, it is the kinetic energy inherent in the flowing water that is converted into electric energy. In nuclear power plants, it is the energy produced by nuclear reactions that are converted into electric energy and harnessed for various purposes. At the lowest level, it is the energy produced by chemical reactions in batteries that are subsequently converted into electrical energy and harnessed to power the various appliances. For instance, solar electricity can be discussed as below to get much understanding about it.

 

Solar Electricity

Solar Electricity is energy from the sun’s rays. You experience it on a daily basis anytime the sun shines. That massive star in our solar system delivers warmth to the earth and light. However, what is happening when families choose to go with solar electricity for their homes?

 

Solar Electricity Fundamentals

Everything begins with our sun’s rays. Sunlight bombards our planet with solar radiation. Most of us know it as UVA and UVB radiation. A great deal of those rays are reflected back into space, but there’s an ample amount of that energy that’s soaked up by the earth to fuel houses all over the planet. Regrettably, technological know-how has not caught up with our fantastic ideas to help save our planet however you can do your part with residential solar electricity.

You have witnessed solar panel systems on rooftops as well as in backyards. They’ve become much sleeker since the time that they initially arrived on the scene. Previously, only people with a good amount of money could have enough money for residential solar electricity however the systems are widely used today.

Every solar panel is made up of photovoltaic cells. These cells usually are manufactured from silicon or some other semi-conductive substance. The cells are usually organized uniformly with both a positive and a negative end to produce the solar panel system. Whenever the suns’ rays hit the solar panels, it is soaked up into the solar cells.

The light energy (photons) strikes the solar cells, and electrons will knock free. All these free electrons proceed through the array and generate the electrical energy you must have to power your entire home. At this time, the electrical power which is generated is DC or direct current. Your house utilizes AC or alternating current therefore the energy must be converted.

This is the point where the remaining system takes over. The electrical energy which is generated by the solar PV (photovoltaic) array, is next handed to a DC disconnect apparatus. This apparatus interrupts the stream of electricity from the array.

Following that, you need to use one of two techniques designed for funneling the electrical energy straight into your home. If you are using a residential solar energy system which is directly linked to your electrical system, the electrical power will traverse an inverter to alter the DC to AC. For anyone who is using a system which uses a battery to keep solar electrical energy for future use, solar electrical power is directed to a battery bank in which it is saved until needed. When you are set to use the energy, it then moves through an inverter to be used by AC outlets in your house.
