Currently, not only are there different types of solar energy, but we also have different types of renewable energy installation. Specifically, we have connected and isolated photovoltaic installations, and in order to choose and make a decision we must take into account multiple factors such as location, electrical consumption needs and also the legislation of each of the places.
There are numerous differences between the two most common types of installations, which is why at PROT energía we want to explain to you in this article what each of the installations consists of and what their main differences are in this article.
What is the connected photovoltaic installation?
We will start by talking about what a connected photovoltaic installation is, and these types of installations are those that are connected to the grid so the consumer can use it during solar hours and when this ends, use the traditional grid.
It is important to mention that this type of installation, together with the fact that the initial investment is much lower than in previous years, has favoured the expansion of the use of solar energy and increased the possibility of installing renewable energy in homes.
In addition, it is also important to highlight that through the connected photovoltaic installations, it is possible to carry out the surplus compensation system by which the excess energy can be compensated and put back into the network.
What does an isolated photovoltaic installation consist of?
Isolated photovoltaic installations refer to those solar energy systems that generate energy independently, that is, the system itself creates energy in a self-sufficient manner and therefore, without any type of connection to the electrical grid.
It is necessary to mention that in order to carry out an isolated installation it will be necessary to have batteries to be able to store the photovoltaic energy that is generated. In this way, the surplus generated in the periods of highest production can be accumulated and thus have energy available at the time when there is a lack of sun and less energy generated.
It is recommended to carry out this type of installation in those places where the electrical network is inaccessible or there is greater difficulty to get to it. It is for this reason that it is common to find isolated photovoltaic installations in rural areas.
Differences between connected and isolated installation
| Installation | Isolated | Connected |
| Works offiline | Yes | No |
| Works when no power is generated | No | Yes |
| Compensation | No | Yes |
| Battery | Yes | Yes |
| Use for home | Yes | Yes |
Advantages of connected and isolated installation
After having discussed what each of the installations consists of, it is important to comment on the main advantages of both the connected and isolated installations.
As we have mentioned, the main characteristic of a connected installation is that it has a network connection to use if necessary. This characteristic also becomes one of the most important advantages, since in the event of possible moments in which demand is greater than production, energy will always be available thanks to the connection of this type of installation.
Regarding the advantages of isolated photovoltaic installations, it is important to comment that what stands out above all is the fact that it is completely independent of electrical companies and therefore, electricity bills are completely dispensed with. This independence is also reflected in the fact that it is completely OWN-sufficient and therefore, you will generate your own energy and can consume it later without problem.
