Photovoltaic solar energy operation

Photovoltaic solar energy operation

In this article we will talk about Photovoltaic solar energy operation. Among the   existing clean and  renewable energies, photovoltaic solar energy  is one of the most widely used in Europe. Unlike Spain, where despite being one of the  European countries with the most solar radiation , there are still numerous legal obstacles to photovoltaic self-consumption.

Greenpeace affirms that  renewable energies in Spain  are so powerful that, with good  sustainable actions , in 2050 the country could generate 10 times more energy than it would need.

Solar Photovoltaic installation  allows you to save on the electricity bill and even if it is self-consumption you can even do without it.

Of course, an initial investment will have to be made to  carry out the photovoltaic installation,  which can be between 10,000 and 15,000 euros depending on the needs.

Operation of a Photovoltaic Solar Installation

The  operation of a photovoltaic installation  in both buildings and homes is the same and is easy to explain, but first you must know the elements (basic or not) that make up a  photovoltaic solar installation .

Photovoltaic solar energy operation

 Photovoltaic solar panels.  It is extremely basic if we want to choose to obtain electrical energy through solar energy.

Network inverters.  This device is used to pass direct current into alternating voltage. The  solar energy  comes in DC and for use in certain appliances need to go to AC.

Solar and photovoltaic batteries.  It is a tank that stores the energy obtained from  photovoltaic panels  to be used when it is deemed appropriate.

Well,  solar energy is  not always available so that the  photovoltaic panel  can generate energy at any time.

Charge regulator.  It is a device that is responsible for preserving  photovoltaic batteries by ensuring  that the battery is not overcharged. If there is no battery in the installation, no regulator is needed either.

Electrical wiring.  All elements are connected with electrical wiring.

How Does a Photovoltaic Installation Work?

1.-  Photovoltaic modules  transform solar radiation into  electrical energy , through the photovoltaic phenomenon.

2.- That energy obtained from the  photovoltaic panels  goes to the charge regulator (if it has it) and from there it goes to the batteries (if it has them).

3.- In the event that there is no regulator or batteries, it goes to the inverter where it becomes  direct voltage.

4.- From there it goes to  the protection panel  that every home has, to later be used in any electrical element.

5.- In the case that we have  solar batteries , the alternative energy is stored until it is demanded by a user of the house, going to points 3 and 4.

Photovoltaic Installation Connected Or Not to the Electric Grid 

There are two types of  facilities :

-The ones  isolated from the electrical network , which are used when the electrical network is far from the consumption points and are especially useful for inaccessible areas of the network.

-The  facilities connected to the grid , in which clean energy is generated and connected to the grid.

 

Price of Photovoltaic Panels

How Much is a Photovoltaic Solar Kit Worth?

How Much Does the Installation of Solar Panels Cost in a House?

The price of an installation of solar panels for a home is very varied, it depends a lot on the  type of photovoltaic panels that is chosen , the size of the installation, but above all it depends on the energy self-sufficiency that this photovoltaic panel system must have.

The  price of a photovoltaic solar kit ranges  from € 600 to € 800 per square meter. The larger the installation, the more the price per square meter will be reduced.

Therefore, it is recommended that the  installation  be done with the intention that it be definitive, without thinking about the possibility of expanding it in a few years, unless there is an agreement with the contracted company to reduce the price.

However, the price of a  photovoltaic solar energy installation  can have an average price between € 7,000 and € 14,000.

How Much Does a Photovoltaic Solar Panel Cost?

Before buying a photovoltaic panel or another, it is convenient to find out about all the  aspects to consider about photovoltaic panels  before purchasing them.

The  average price of photovoltaic panels  has been falling in a very few years, now we can find  photovoltaic panels for € 200  or even less.

The  cheapest photovoltaic panels  are  thin-film  and the most expensive are  monocrystalline silicon .

Although the  price of a photovoltaic panel  is the first thing a potential buyer fixes on.

The truth is that you have to do a preliminary study on the home or house before thinking about acquiring the most economical module, because it is possible that with an investment of 2 or 3 photovoltaic panels with better benefits, more energy is obtained than with 6 or 7 cheaper or cheaper photovoltaic panels.

How Many Solar Panels Do You Need To Power A House?

Calculating photovoltaic panels  is a busy but easy task to explain with videos and an example, as was done in the article on  Calculating a solar panel installation in a home .

It is  important  not to skip this step, because a previous study helps to choose the most correct option  .

The following video shows in a simple and visual way how  a photovoltaic energy installation works , how to  save on electricity bills  and increase  energy efficiency  in a home.
