Which photovoltaic installation suits you and why

First of all, the sun's rays hit the solar cells that make up each of the solar panels of the photovoltaic installation. These, in turn, are made of semiconductor materials, some negatively charged and others positively charged. And thanks to this, the photovoltaic effect takes place with which generates electricity.

Operation of a photovoltaic solar installation

At this point, and having understood that the solar panels of all photovoltaic installations generate electricity from the sun, you are probably wondering: But what exactly is the photovoltaic effect? ​​ What happens inside the solar panels to make this possible? Keep reading, and we'll explain it to you!

The solar cells that make up solar panels absorb light rays from the sun because electrons (both negative and positive) interact with each other generating electrical current. And we take advantage of this current thanks to the fact that the inverter transforms it into alternating current, with which we can power the electrical appliances and devices of our home.

Now, from this point the operation of your photovoltaic installation will vary depending on whether it is a solar installation that is connected to the electrical network or if, on the contrary, you have a isolated solar installation. But this is something that we will dwell on a little later.

How much does a photovoltaic solar installation cost?

If you wonder how much it costs to have a photovoltaic installation in your home, you should know that depending on the type of use you are going to give it, you will find one price or another.

However, as a guide, although the price range of a solar installation is quite wide, a basic isolated solar installation is in around €300. But an installation of better quality and with a higher power can reach 50. €000. One price or another depends on the type of photovoltaic installation that we need (isolated, hybrid or connected to the grid), on its characteristics , and of course, the electricity consumption that it has to cover.

How much does a photovoltaic solar installation cost per kW?

When determining how much a photovoltaic installation or solar installation costs per kW, everything will depend on the size of the installation. In this way, the larger the photovoltaic installation is, the price per kWp will be lower.

To give you an idea, a 3 kW photovoltaic installation can be between €4,500 and €6,000 depending on the quality of the components. So, in this case, the price per kWp would be around €2000.

And in the same way, if we go for a larger solar installation, of about 10 kW, the price rises to a range between €10,000 and €15,000 €. Costing each kWp close to €1500.

What does a photovoltaic installation have?

A photovoltaic installation is made up of the solar panels and the inverter, in addition of the wiring and the structure on which it is installed.

What benefits does the photovoltaic system have?

The main motivation for deciding on a photovoltaic installation is, without a doubt, the savings on the electricity bill. But this is not the only benefit derived from a solar installation in your home.

If you have a photovoltaic installation, your house will increase in value if at any time you decide to sell it and you can benefit from subsidies for the promotion of renewable energies. In addition, you will be contributing to the reduction of the carbon footprint and sustainability with the use of clean and renewable energy such as solar energy.

Whether it is to avoid unnecessary consumption or as a backup during power outages, the AC200Max is the perfect solution. Take advantage of this opportunity to save energy and increase the value of your home with Bluetti Power!

Photovoltaic installation connected or not to the electrical grid

If you want to have a photovoltaic or solar installation in your home, the first thing to do is decide what type of installation you want. In this sense, as we have mentioned previously, you can choose between a photovoltaic installation connected to the grid, or an isolated photovoltaic installation (not connected to the network).

With this type of solar installation, your home will have energy from the solar panels as a first resource, and secondly, it will obtain power from the conventional electric grid if necessary.

However, if you have a isolated photovoltaic installation, this will not be connected to the conventional electrical grid. Instead, it will be connected to your self-consumption network, so in this type of solar installation it is essential to have a solar battery that is capable of storing the energy you obtain and you do not get to consume.

This is a type of photovoltaic installation that allows you to be totally self-sufficient and independent from the electricity grid. And in this sense, the better your solar battery is, the better your autonomy will be! So the best thing, without a doubt, is to opt for a BLUETTI home battery, a type of battery modular easy to use and expandable, with which you will never run out of energy!

And now that you know what a photovoltaic installation is and which one you should have in your home, all that remains is for you to enjoy your solar energy!
