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.
Photovoltaic solar energy operation
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.
A 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 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.
